I said that the system is chaotic and that the models are based on probability-density functions.

And neither can anyone here on this NG, although a few pretend to themselves that they can. You see, they read a book... -- Ed Huntress --jsw |

The timer will come on for one hour, if necessary, each day before I get up. I'm not going to feed the grid because that means I'd have to get a net meter. I simply disconnected the lower heater element so the bottom water warms from ground to basement temperature by wood heat. The top element operates normally from the grid, and the sink spray hose in my shower reduces water use enough by shutting off when released for the heater to keep up. The wood stove heats laundry or dish water as hot as needed. One of the thermocouple channels displayed upstairs is dedicated to water or food temperature, with a new Inconel probe because I don't know the previous use of the second-hand probes. Doesn't Oregon have some regulation on how hot the water should be? Mine runs 115~120F as the thermostat cycles. The lower heater's thermostat is maxed out. I switch it back on when an ice storm threatens to provide for several hot showers after the hard work of storm cleanup. This also sterilizes the tank at least once a year although I'm on treated town water. --jsw |

The timer will come on for one hour, if necessary, each day before I get up. I'm not going to feed the grid because that means I'd have to get a net meter. That's a case where I think the economics favor grid power, because of the high cost and limited cycle life of vented deep-cycle batteries. I'm still experimenting with how to best use them. I think the answer is to recharge them to the solar controller's lower VRLA/AGM voltage cutoff setting so they don't release gas indoors, and then schlepp them outdoors after the blackout ends to top off and equalize them per the maker's instructions at the higher voltage that mixes the stratified electrolyte by bubbling. That's one of those inconvenient solutions only the inventer would tolerate, and impractical for batteries heavier than Group 31. When recharging quickly from a generator I feed my unregulated, Powerstat-controlled homebrew 35V 15A power supply through the solar controller's panel input to make use of its automatic charge cutoff. My filler-cap batteries don't bubble noticeably at the 13.6V AGM cutoff. The "book" calls 14.3V the threshold of significant gas generation. I can't judge the rate by just looking but 14.0 to 14.3 is where the bubbling becomes continuous, and also where fine acid mist comes out. I couldn't see well enough through the spattered food wrap to describe bubbling as more than "substantial" at 14.8V. I've run a gas generation test in ?? company's lab on their lead-acid batteries. While I can't reveal details the results were similar. The Interstate battery I put in the truck in 2002 receives a top-off charge every month or two and is still in good condition, judging by the electrolyte gravity and the time it will run the headlights without dropping too far. --jsw |

Snicker.... http://www.urbanheatislands.com/\ http://wattsupwiththat.com/2015/11/1...-temperatures/ If you can follow it, this article explains how CO2 dominates the heat radiation lost to space from the upper atmosphere at certain wavelengths, allowing us to measure its contribution to Earth's energy flow without the confusion from other sources that the maps show. http://clivebest.com/blog/?p=1169 "At these levels there is little water vapour and CO2 dominates the energy loss." "Therefore the main physics arguement supporting enhanced global warming caused by increasing levels of CO2 is the in height and thereby lower temperature of the effective radiating level of the atmosphere to space." "As we rise up in the atmosphere so the density falls exponentially and only at heights of 8-9 kms does the atmosphere then become transparent in the main CO2 bands allowing energy loss direct to space." "Feedback Effects" exposes the main weakness of AGW theory, the unproven assumption that water will amplify the admittedly tiny contribution of CO2 to global warming. This is analogous to measuring rainfall by observing the water flowing over a dam. There are too many ways that water can enter the lake, but only one way for it to leave, and the output has to balance the input; the lake can't store much extra water because a small rise in its level greatly increases the flow over the dam. Similarly measuring CO2's radiative emission into space with satellites bypasses the complication of all the ways CO2 receives and -briefly- stores heat from the Earth. CO2 can't permanently trap heat, only modulate its release. --jsw Be that as it may, ice core studies virtually prove that increases in temperature and increases in CO2 in the atmosphere have been occurring at the same time for something like 400,000 years. While this may not "prove" cause and effect they would certainly make one think that there might be a relationship. -- cheers, John B. It certainly doesn't prove there was an industrial society filling the air with CO2 400,000 years ago.

"Therefore the main physics arguement supporting enhanced global warming caused by increasing levels of CO2 is the in height and thereby lower temperature of the effective radiating level of the atmosphere to space." "As we rise up in the atmosphere so the density falls exponentially and only at heights of 8-9 kms does the atmosphere then become transparent in the main CO2 bands allowing energy loss direct to space." "Feedback Effects" exposes the main weakness of AGW theory, the unproven assumption that water will amplify the admittedly tiny contribution of CO2 to global warming. This is analogous to measuring rainfall by observing the water flowing over a dam. There are too many ways that water can enter the lake, but only one way for it to leave, and the output has to balance the input; the lake can't store much extra water because a small rise in its level greatly increases the flow over the dam. Similarly measuring CO2's radiative emission into space with satellites bypasses the complication of all the ways CO2 receives and -briefly- stores heat from the Earth. CO2 can't permanently trap heat, only modulate its release. --jsw Be that as it may, ice core studies virtually prove that increases in temperature and increases in CO2 in the atmosphere have been occurring at the same time for something like 400,000 years. While this may not "prove" cause and effect they would certainly make one think that there might be a relationship. -- cheers, John B. It certainly doesn't prove there was an industrial society filling the air with CO2 400,000 years ago.

That's a case where I think the economics favor grid power, because of the high cost and limited cycle life of vented deep-cycle batteries. That it does, but what happens when (not if) the grid goes tits-up? I'm still experimenting with how to best use them. I think the answer is to recharge them to the solar controller's lower VRLA/AGM voltage cutoff setting so they don't release gas indoors, and then schlepp them outdoors after the blackout ends to top off and equalize them per the maker's instructions at the higher voltage that mixes the How often are you equalizing? The last article I read said that it drops battery life considerably if you do it very often. I think the article was in HomePower mag. No equalization can drop the life, too, so there's a balance. stratified electrolyte by bubbling. That's one of those inconvenient solutions only the inventer would tolerate, and impractical for batteries heavier than Group 31. Why not vent them well rather than schlepping? MUCH less work. Enclosed battery space, right? Fan on the inside, window to the outside? For a more exciting removal of the hydrogen, just burn it off. (Disclaimer: Kids, don't try this at home.) I need to do something better with my solar battery set. The original is outside in a box, which means it chills in the winter and boils in the summer. Maybe I'll build a foam-insulated cover for it, with vents, then figure out a better solution for the larger battery set on the new panels when I do get them. Battery watering sets aren't too expensive, and auto-fill beats frequent checking. Cheap insurance. When recharging quickly from a generator I feed my unregulated, Powerstat-controlled homebrew 35V 15A power supply through the solar controller's panel input to make use of its automatic charge cutoff. Good idea. Generators are also more costly than grid power. My filler-cap batteries don't bubble noticeably at the 13.6V AGM cutoff. The "book" calls 14.3V the threshold of significant gas generation. I can't judge the rate by just looking but 14.0 to 14.3 is where the bubbling becomes continuous, and also where fine acid mist comes out. I couldn't see well enough through the spattered food wrap to describe bubbling as more than "substantial" at 14.8V. Um, "food wrap"? Makeshift battery enclosure, Mickey? Whatever works, wot? I've run a gas generation test in ?? company's lab on their lead-acid batteries. While I can't reveal details the results were similar. Good knowledge to have. The Interstate battery I put in the truck in 2002 receives a top-off charge every month or two and is still in good condition, judging by the electrolyte gravity and the time it will run the headlights without dropping too far. 13+ years? Not bad. I just replaced my Tundra battery last year, so I got 9 on the original. Other battery tech: Ickterstate- I bought one rebuilt nicad tool battery from the local Interstate and won't ever buy anything from them again. It was less powerful than the original with the bad cell, and they said "It tests to spec. No warranty necessary." I wish I'd checked specs on the original cells, but I'd bet the replacements had a significantly lower capacity. The NiMHs in the Bosch Impactor lasted 5 years and were good when I sold the kit. Lithiums in the new Makita are still going strong 5+ years later. Lithiums in the $500 Milwaukee set I won at a fair are still going strong at about a year old. g I wish LiFePO batteries were 10x cheaper now. I'd get a few KW of those instead of LA. Tesla keeps making strong drops in pricing on their battery tech. A couple 10kw modules would be nice, eh? Or maybe solar electrolysis to power fuel cells? -- Our main business is not to see what lies dimly at a distance but to do what lies clearly at hand. --Thomas Carlyle |

That it does, but what happens when (not if) the grid goes tits-up? We return to the 1800's and DIY steam power, the Good Old Days. But I suspect that a deteriorating, unreliable electricity supply as in India would switch the helplessly codependent Greenies from blocking construction to screaming about their NEEDS!! before it did more than annoy the more technically competent of us. This neighborhood bands together and shares resources, one generator serves three houses. I contribute 100' extension cords and repairs to carbs and electrical systems, and one of my Coleman gennys has spent almost its entire operating life powering the house across the street. https://en.wikipedia.org/wiki/2012_India_blackouts "The nation suffers from frequent power outages that last as long as 10 hours." How often are you equalizing? The last article I read said that it drops battery life considerably if you do it very often. I think the article was in HomePower mag. No equalization can drop the life, too, so there's a balance. Every manufacturer's advice is slightly different, and a battery's behavor changes as it ages. I think the least damaging method that's still adequate is to charge at 1% to 2% of the 20-hour-rate capacity until the voltage rises to 14.8V for flooded or whatever the maker says for AGMs. I charge unmarked ones to 14.4V at less than half an amp. Usually I use an unregulated rectifier + capacitor charger adjusted to the individual battery with a Variac. The cap I added to the charger stabilizes the voltage and current meter readings. "Dumb" rectifier chargers automatically taper down the current as the voltage rises. The next time I walk by I check the meters and turn up the Variac. One is a 1970's Schauer charger with a small 3 Amp Variac added in, the other a homebrew that puts out 0 - 35V at up to 15A, with a 1/10 Farad filter cap. Since they don't have an output regulator they aren't susceptible to damage from battery voltage being fed back into the unpowered circuit if the AC is interrupted. You can protect a lab supply from that with a series diode but then the voltmeter will be useless. I don't equalize vehicle batteries very hard unless the hydrometer or charging behavior reveals a weak cell. The smaller colored-bead type is enough to show significant differences and works better on small riding mower batteries with small caps and little free liquid.. If they are sulfated / corroded / whatever and won't accept current at 14.4V I apply 15V to 16V and keep an eye on the current, which is typically under 100mA until they start to recover, then it rises and may need to be limited due to the otherwise excessive charging voltage. This is the case where a Smart Charger gives up, but a smart user can salvage the battery. These numbers are all from makers' data sheets. I just pick the more conservative ones and procedures that can safely be left unattended. My 5-year-old HF '45W' kit supplies 0.6A per panel, making it good current-limited source for gently conditioning batteries. I made an LM350 variable regulator to fine-tune the charging voltage and current. An LM338 will pass more current, I chose the LM350 to protect some nice 3A meters I found. http://www.eleccircuit.com/adjustabl...a-using-lm338/ D1 protects IC1 from higher voltage on the output than input, as I mentioned above. Active, adjustable current limiting is conspicuously absent from commercial battery chargers. I've read that "Pulse" desulfating is really only a cheap substitute for building in a current limiter. At Segway I learned how to use a lab-type adjustable power supply to meet almost any battery charging requirement except fast-charging NiCd and NiMH. The problem is that it requires a careful, attentive and well informed user such as an electronic lab technician, NOT the average mechanical engineer. stratified electrolyte by bubbling. That's one of those inconvenient solutions only the inventer would tolerate, and impractical for batteries heavier than Group 31. Why not vent them well rather than schlepping? MUCH less work. Enclosed battery space, right? Fan on the inside, window to the outside? For a more exciting removal of the hydrogen, just burn it off. (Disclaimer: Kids, don't try this at home.) I need to do something better with my solar battery set. The original is outside in a box, which means it chills in the winter and boils in the summer. Maybe I'll build a foam-insulated cover for it, with vents, then figure out a better solution for the larger battery set on the new panels when I do get them. Battery watering sets aren't too expensive, and auto-fill beats frequent checking. Cheap insurance. When I rebuild the tool shed I plan to leave space for battery shelves in a separate cabinet on an outside wall. I've had too much trouble containing liquids like hydraulic fluid to assume I could safely control invisible hydrogen. I don't have or plan to acquire nearly enough batteries to fill it so the remaining space will probably be for lawn and garden chemicals. .. How much of an actual problem has the temperature swing been for you? Batteries work well enough outdoors in cars here, where the temps run from +100F to -10F. When I lived an hour further north it sometimes dropped to -30F. Being able to watch and limit the charging current spares me from the uncertainties of voltage-controlled charging. I use the voltage-vs-temperature table only to determine state of charge and know when they are fully topped off.. Good idea. Generators are also more costly than grid power. I once figured about half a buck per KWH. My system is for standy use only, but I need to test it and exercise the generators. The Interstate battery I put in the truck in 2002 receives a top-off charge every month or two and is still in good condition, judging by the electrolyte gravity and the time it will run the headlights without dropping too far. 13+ years? Not bad. I just replaced my Tundra battery last year, so I got 9 on the original. Did you do anything to maintain it? I caught one cell on my truck battery dropping out a few years ago and began charging it and checking the level more often. It seems to have recovered. ... I wish LiFePO batteries were 10x cheaper now. I'd get a few KW of those instead of LA. Tesla keeps making strong drops in pricing on their battery tech. A couple 10kw modules would be nice, eh? A friend is getting a quote from Solar City, which is connected to Tesla. When the engineers come by I'm going to find out as much as I can about the technical possibilities. Their site is useless. Segway stores large pallets of Lithium batteries at the factory. The fire department's practice response for a large Class D fire next to a river was awesome. http://www.fire-extinguisher101.com/class-d-fires.html I needed to use a very reactive Lithium compound for an organic synthesis and a helpful grad student came over to break off a chunk from the rock-like mass in the can. As soon as he tapped the chisel it burst into brilliant crimson flame and all we could do was pull down the fume hood door and watch it all go up, then go request another can. --jsw |

This is what the experts know you should be doing to reduce your personal carbon footprint: http://cotap.org/reduce-carbon-footprint/ They forgot about hanging laundry outdoors, the heater in an electric dryer is a huge unnecessary waste. Since you have a lathe you can convert round trash barrels ($12 at HD) into inexpensive rain barrels ($100 at HD) and avoid watering your lawn with treated drinking water by threading the barbed end of a hose coupler and mounting it in the lower side wall, with an O ring on the outside and the appropriate stainless nut and washer on the inside. Landscaping fabric over hardware cloth across the top will keep out gutter debris and mosquitos. During the winter I store chainsaw chips and chopped-up tree branches from the yard in the barrels, to use as kindling. Pressing on and clamping a short piece of hose onto the barbs inside might be enough to make the watertight seal, but the inside bottom of the barrel is a difficult place to apply much force. My carbon footprint went down in 1971, when I grokked Earth Day for the first time. I replaced my front lawn with chips and plantings of shrubs and flowers with a single drip irrigation system for the entire 1/3 acre of my land. All but one of my light bulbs (75w pump house warmth) is either CFL or LED. My electric bill is $40/mo, and I have a new timer for the electric water heater. Once I get the new solar panels installed, I'll also have a 24v 900w element going into that water heater, replacing one of the two 240vac energy suckers. The timer will come on for one hour, if necessary, each day before I get up. I'm not going to feed the grid because that means I'd have to get a net meter. My sister has a rain barrel diverter for me to pick up. So far, it's legal to catch my rain in Oregon, unlike Colorado. That just floors me, that you're fined for NOT allowing runoff in CO! I fill 1/3 of a 13gal tall kitchen trash bag each week and recycle the rest. All paper, cardboard, plastic, cans, and bottles are recycled.

"Therefore the main physics arguement supporting enhanced global warming caused by increasing levels of CO2 is the in height and thereby lower temperature of the effective radiating level of the atmosphere to space." "As we rise up in the atmosphere so the density falls exponentially and only at heights of 8-9 kms does the atmosphere then become transparent in the main CO2 bands allowing energy loss direct to space." "Feedback Effects" exposes the main weakness of AGW theory, the unproven assumption that water will amplify the admittedly tiny contribution of CO2 to global warming. This is analogous to measuring rainfall by observing the water flowing over a dam. There are too many ways that water can enter the lake, but only one way for it to leave, and the output has to balance the input; the lake can't store much extra water because a small rise in its level greatly increases the flow over the dam. Similarly measuring CO2's radiative emission into space with satellites bypasses the complication of all the ways CO2 receives and -briefly- stores heat from the Earth. CO2 can't permanently trap heat, only modulate its release. --jsw Be that as it may, ice core studies virtually prove that increases in temperature and increases in CO2 in the atmosphere have been occurring at the same time for something like 400,000 years. While this may not "prove" cause and effect they would certainly make one think that there might be a relationship. -- cheers, John B. It certainly doesn't prove there was an industrial society filling the air with CO2 400,000 years ago. We can safely assume that the temperature and CO2 variations were natural. http://www.livescience.com/44330-jur...n-dioxide.html I want to see the questions researched honestly and openly, instead of suppressing data that doesn't support prejudices. The point was that the CO2 and higher temperatures did coincide. I don't think that the ice core studies claimed any cause and effect... as I believe I said. Quite obviously temperature and, or, CO2 changes some 400,000 years ago were not the results of human endeavor :-) -- cheers, John B. This shows one reason why the higher temperature could be a cause rather than an effect. http://www.engineeringtoolbox.com/ga...er-d_1148.html Cold water can hold more gas than hot water. Also it can hold many times as much CO2 as oxygen or nitrogen. I suspect that the truth of the matter is that the temperature is getting warmer and no one actually knows why nor whether this is simply an anomaly or indicative of the beginning of a major temperature cycle. -- cheers, John B. |

Get better suspicions. The effect was predictable, has a known cause. No knowledge, however, predicts any natural recovery to the initial state, as a "cycle" would suggest. The "simply an anomaly" label suggests we should not try to understand it. Related language: "ideopathic", "unknown and unknowable", "great mystery", "will of God". People aren't capable of not trying to understand, though. That's why we put the 'sapiens' in 'homo sapiens'. |

No, irrelevant. You don't ignore the heat capacity of oceans, soil, and dismiss the temperature of lower atmosphere that's in contact with the oceans and soil, if you want a temperature measurement. That upper-atmosphere data is of such a tiny bit of matter, by comparison, that it can be safely ignored. The temperature of the vacuum of space is measurable; it can't tell you anything about global warming, either. Yet the global temperature has remained unchanged for 58 yrs.. In the last 58 years I recall, it has been cold every winter and warm every summer. What planet are you from? Were you dropped on your head recently, or did you have a stroke? Off your meds?

But I suspect that a deteriorating, unreliable electricity supply as in India would switch the helplessly codependent Greenies from blocking construction to screaming about their NEEDS!! before it did more than annoy the more technically competent of us. This neighborhood bands together and shares resources, one generator serves three houses. I contribute 100' extension cords and repairs to carbs and electrical systems, and one of my Coleman gennys has spent almost its entire operating life powering the house across the street. Perhaps Gunner's Cull will "reduce" the Green needs. wink https://en.wikipedia.org/wiki/2012_India_blackouts "The nation suffers from frequent power outages that last as long as 10 hours." How often are you equalizing? The last article I read said that it drops battery life considerably if you do it very often. I think the article was in HomePower mag. No equalization can drop the life, too, so there's a balance. Every manufacturer's advice is slightly different, and a battery's behavor changes as it ages. I think the least damaging method that's still adequate is to charge at 1% to 2% of the 20-hour-rate capacity until the voltage rises to 14.8V for flooded or whatever the maker says for AGMs. I charge unmarked ones to 14.4V at less than half an amp. OK. Usually I use an unregulated rectifier + capacitor charger adjusted to the individual battery with a Variac. The cap I added to the charger stabilizes the voltage and current meter readings. "Dumb" rectifier chargers automatically taper down the current as the voltage rises. The next time I walk by I check the meters and turn up the Variac. More automation, I see. One is a 1970's Schauer charger with a small 3 Amp Variac added in, the other a homebrew that puts out 0 - 35V at up to 15A, with a 1/10 Farad filter cap. Since they don't have an output regulator they aren't susceptible to damage from battery voltage being fed back into the unpowered circuit if the AC is interrupted. You can protect a lab supply from that with a series diode but then the voltmeter will be useless. Useless or merely off by .3v? I don't equalize vehicle batteries very hard unless the hydrometer or charging behavior reveals a weak cell. The smaller colored-bead type is enough to show significant differences and works better on small riding mower batteries with small caps and little free liquid.. I've forgotten to ask about your battery stack. Whatcha got? If they are sulfated / corroded / whatever and won't accept current at 14.4V I apply 15V to 16V and keep an eye on the current, which is typically under 100mA until they start to recover, then it rises and may need to be limited due to the otherwise excessive charging voltage. This is the case where a Smart Charger gives up, but a smart user can salvage the battery. These numbers are all from makers' data sheets. I just pick the more conservative ones and procedures that can safely be left unattended. What kind of new life do you get from the salvaged batts? My 5-year-old HF '45W' kit supplies 0.6A per panel, making it good current-limited source for gently conditioning batteries. I made an LM350 variable regulator to fine-tune the charging voltage and current. An LM338 will pass more current, I chose the LM350 to protect some nice 3A meters I found. http://www.eleccircuit.com/adjustabl...a-using-lm338/ D1 protects IC1 from higher voltage on the output than input, as I mentioned above. I picked up some LM317s + heatsinks cheap, and was thinking about the same use. Active, adjustable current limiting is conspicuously absent from commercial battery chargers. I've read that "Pulse" desulfating is really only a cheap substitute for building in a current limiter. At Segway I learned how to use a lab-type adjustable power supply to meet almost any battery charging requirement except fast-charging NiCd and NiMH. The problem is that it requires a careful, attentive and well informed user such as an electronic lab technician, NOT the average mechanical engineer. g stratified electrolyte by bubbling. That's one of those inconvenient solutions only the inventer would tolerate, and impractical for batteries heavier than Group 31. Why not vent them well rather than schlepping? MUCH less work. Enclosed battery space, right? Fan on the inside, window to the outside? For a more exciting removal of the hydrogen, just burn it off. (Disclaimer: Kids, don't try this at home.) When I rebuild the tool shed I plan to leave space for battery shelves in a separate cabinet on an outside wall. I've had too much trouble containing liquids like hydraulic fluid to assume I could safely control invisible hydrogen. I don't have or plan to acquire nearly enough batteries to fill it so the remaining space will probably be for lawn and garden chemicals. I have an old fridge for chemicals. How much of an actual problem has the temperature swing been for you? Batteries work well enough outdoors in cars here, where the temps run from +100F to -10F. When I lived an hour further north it sometimes dropped to -30F. No problems, but I'm not heavily using the batteries, nor am I carefully monitoring their capacities. Not a prob, I don't think. Temps (most years) run 20-109F, with (every few years) a few days down to 5F. I've had one burst pipe (outside plumbing, valved!) and one freezeup (4 hours of portable 1.5KW heater under house fixed that) in the 14 years I've been here. The first damage I get in plumbing in the future, I'll replace all the old galv pipe with PEX and put foam insulation around all of it, for good measure. It won't burst again. I'd likely get a better flow, too. Pipes are ca 1967. Being able to watch and limit the charging current spares me from the uncertainties of voltage-controlled charging. I use the voltage-vs-temperature table only to determine state of charge and know when they are fully topped off.. OK. Do you do full-lot, batches, or individual battery charging? Good idea. Generators are also more costly than grid power. I once figured about half a buck per KWH. My system is for standy use only, but I need to test it and exercise the generators. Solar used to be 25-cents/kWh, but is less now. I'm figuring a cost of about a buck a watt for purchase of the system, so I'll need to get $3k together for the systems I want. One quote for south-facing flat panel setup: Here in GP, 1.8KW of panels will produce 2,277KWH annually, about $0.05/KW over a 25 year lifetime. Hmm, forgot replacement batteries ($2k): $0.10 per. No gas purchase/storage/fumes/refills, no rebuilds, no tuneups, just pure energy. I love the simplicity of solar. The Interstate battery I put in the truck in 2002 receives a top-off charge every month or two and is still in good condition, judging by the electrolyte gravity and the time it will run the headlights without dropping too far. 13+ years? Not bad. I just replaced my Tundra battery last year, so I got 9 on the original. Did you do anything to maintain it? I caught one cell on my truck battery dropping out a few years ago and began charging it and checking the level more often. It seems to have recovered. No. It never seemed to use water, and after 4 years, I don't even look at batteries, I just replace them (in vehicles.) ONE stranding per lifetime is all you need to move to that route. I love canned terminal protectant. I clean the terms, spray them down, and seldom have to approach them again during the life of the battery. I heart purple goo. I wish LiFePO batteries were 10x cheaper now. I'd get a few KW of those instead of LA. Tesla keeps making strong drops in pricing on their battery tech. A couple 10kw modules would be nice, eh? A friend is getting a quote from Solar City, which is connected to Tesla. When the engineers come by I'm going to find out as much as I can about the technical possibilities. Their site is useless. It's a fact-filled site...if you're a clueless sheeple consumer. Please let me know what you find out, although I'll never be able to afford one, let alone two. Segway stores large pallets of Lithium batteries at the factory. The fire department's practice response for a large Class D fire next to a river was awesome. http://www.fire-extinguisher101.com/class-d-fires.html I'll keep a pound or two of baking soda handy for my metal fires. I needed to use a very reactive Lithium compound for an organic synthesis and a helpful grad student came over to break off a chunk from the rock-like mass in the can. As soon as he tapped the chisel it burst into brilliant crimson flame and all we could do was pull down the fume hood door and watch it all go up, then go request another can. Ouch! But pretty, huh? -- Our main business is not to see what lies dimly at a distance but to do what lies clearly at hand. --Thomas Carlyle |

But I suspect that a deteriorating, unreliable electricity supply as in India would switch the helplessly codependent Greenies from blocking construction to screaming about their NEEDS!! before it did more than annoy the more technically competent of us. This neighborhood bands together and shares resources, one generator serves three houses. I contribute 100' extension cords and repairs to carbs and electrical systems, and one of my Coleman gennys has spent almost its entire operating life powering the house across the street. Perhaps Gunner's Cull will "reduce" the Green needs. wink Historically the Left has begun the revolutions, violently, and the Right has ended them, even more violently. https://en.wikipedia.org/wiki/Paris_Commune https://en.wikipedia.org/wiki/Bavarian_Soviet_Republic https://en.wikipedia.org/wiki/Dirty_War "Trade unionists were targeted for assassination by the Peronist and Marxist guerrillas as early as 1969." Usually I use an unregulated rectifier + capacitor charger adjusted to the individual battery with a Variac. The cap I added to the charger stabilizes the voltage and current meter readings. "Dumb" rectifier chargers automatically taper down the current as the voltage rises. The next time I walk by I check the meters and turn up the Variac. More automation, I see. I built automated test equipment for a living back in the relay logic days. One is a 1970's Schauer charger with a small 3 Amp Variac added in, the other a homebrew that puts out 0 - 35V at up to 15A, with a 1/10 Farad filter cap. Since they don't have an output regulator they aren't susceptible to damage from battery voltage being fed back into the unpowered circuit if the AC is interrupted. You can protect a lab supply from that with a series diode but then the voltmeter will be useless. Useless or merely off by .3v? The drop varies with the current. The Schottkys I bought from China for my leaky second-hand roof panels have forward drops clustered at or above the top end of the data sheet value, around 0.4V, and barely meet the reverse breakdown spec. The MDQ-100A, 100A 1600V bridge rectifier I just bought to add to a welder looks good so far, the megger reads over 500 megohms at 500V reverse and Vf is 0.49V on my DMM. I haven't set up to measure Vf at 20A DC yet. I've forgotten to ask about your battery stack. Whatcha got? I gotta pair of 105A marine batteries and a small assortment of used gel and AGMs, some given to me as dead, some that had been swapped on a maintenance schedule. I trade in a hopeless ones when I buy a new battery, so they don't just pile up. I'd rather turn them in and use Lithiums if those become economically practical. The engineers at Segway didn't let anything that couldn't be sold to customers but still functioned go to waste. The scrap bins were conveniently beside the exit, and anything good they came up with could be demonstrated on Frog Days. As new guy I was too far down in the queue to get anything valuable. The in-house machines we rode around on had batteries with perhaps half or less of their original capacity left. The still-good original car battery and the U1R pulled from my tractor for the winter are in marine battery boxes with fused charging leads brought out to 45A Andersons. This way there's no spark within the box when I top them off, they are easy to handle and the terminals are covered. I turned my unused stock of nice flexible silicone-insulated wire into extension cables for battery charging. What kind of new life do you get from the salvaged batts? I've had no luck restoring AGMs, and can get perhaps three more years from U1 lawn tractor batteries with filler caps after an automatic charger stopped charging them, IOW four times their normal life. I haven't tried salvaging deep discharge batteries from golf carts or forklifts yet. That will depend on how easy they are to obtain, and to dispose of. Once batteries start to go they need frequent attention to keep them alive, which can become an onerous chore for little return. I've lost two brand new AGMs that I put in the jump starter and forgot to keep charged for a couple of years. My 5-year-old HF '45W' kit supplies 0.6A per panel, making it good current-limited source for gently conditioning batteries. I made an LM350 variable regulator to fine-tune the charging voltage and current. An LM338 will pass more current, I chose the LM350 to protect some nice 3A meters I found. http://www.eleccircuit.com/adjustabl...a-using-lm338/ D1 protects IC1 from higher voltage on the output than input, as I mentioned above. I picked up some LM317s + heatsinks cheap, and was thinking about the same use. I replaced an LM317 with the LM350 because it can handle the HF kit's full output without the risk of frying my pretty 3 Amp Triplett 321 ammeter. The LM317 was enough to top off the vehicle batteries, though, as the current soon dropped to around half an Amp. . OK. Do you do full-lot, batches, or individual battery charging? The roof array charges the 24V pair for the APC in series, and a DPDT switch on the voltmeter panel lets the smaller 12V HF kit top off each individually, since they don't quite match in capacity. They are both the same model from Batteries Plus, one bought a few years after the other when I acquired the 24V APC UPS. The wires to the switch are fused at the battery boxes because they create a possible shorting hazard if the switch malfunctions. I also made the voltage and current sense lead connections to the Bayite shunt with wired in-line fuse holders. Solar used to be 25-cents/kWh, but is less now. I'm figuring a cost of about a buck a watt for purchase of the system, so I'll need to get $3k together for the systems I want. One quote for south-facing flat panel setup: Here in GP, 1.8KW of panels will produce 2,277KWH annually, about $0.05/KW over a 25 year lifetime. Hmm, forgot replacement batteries ($2k): $0.10 per. No gas purchase/storage/fumes/refills, no rebuilds, no tuneups, just pure energy. I love the simplicity of solar. The big unknown in the cost estimate is how many cycles the batteries will give you, expecially if they aren't fully recharged each time. My system won't fully recharge them automatically because it's set to 13.6V each to avoid hydrogen. I have them for power outages instead of continuous use and plan to fully recharge them afterwards, quickly outdoors or slowly over several days from the HF kit which is barely enough to make them bubble very lightly just before it shuts off. Segway stores large pallets of Lithium batteries at the factory. The fire department's practice response for a large Class D fire next to a river was awesome. http://www.fire-extinguisher101.com/class-d-fires.html I'll keep a pound or two of baking soda handy for my metal fires. It's good to have around lead batteries too, for the acid. Don't buy a Hoverboard. I shim up the back of my Dell laptops to allow airflow under the battery and to finger-check for heat. Probably the batteries that didn't catch fire in 2006 are OK now. --jsw |
