That reminds me of a friend who used to have a little Mazda 121.
She thought servicing and and oil changes were a total con and
didn't need doing.

I don't know how but she wasn't wrong. She ran that car from
new until it had done 120,000 miles without ever once changing
the oil. Or the spark plugs. Or any belts and such things.

I take it the AA just changed things for her each time it broke down?

Or it didn't break down and so nothing needed to be changed.

My Golf did even more miles than that and didn't need any of those
changed.

How can you possibly drive 100,000 miles when you spend 24/7 on your
computer?

I don't. And in those days I drove to and from work at least
once most days and did lots of long distance driving too.

Saw an article on Facebook saying you could power your house all day with

Of course if that power consisted of a few dim LEDs for a few hours, you
maybe could. Otherwise, sounds like one of harry's posts.

Are we back to your 'DIY computer psu chair' thread?

In any system you have input energy, losses and output energy. If you
try to human-power something that is capable of producing loads more
in the way of output power than the human could ever provide then the
chances are the background losses will also be quite high.

A good example of this would be Cedric Lynches electric / solar
outboard motor design.

http://www.eboat.org.uk/images/members/DSCF0540.JPG

http://saiettagroup.com/team/ (Scroll down to Cedric)

He found that if you used a conventional sealed underwater metal
gearbox, with it's oil lubrication and oil retaining seals, the
background losses (drag) would be considerable, compared with the
typical energy available associated with such things.

So, he designed an underwater gearbox that could be lubricated by
(river) water and therefore there was no need for the oil and hence
the 'lossy' seals. ;-)

So, if you want to (human) power something that requires 200 W then
you would probably be better off with a generator good for that and a
bit, rather than something good for 10 kW etc.

A good example of overloading a (human powered) generator is trying to
run 10W lamps on your bicycle dynamo.

This relaively unfit sedentary human only wants to rock gently to and fro but utilising the entire (14 stone) body mass gently.

Is it because you have the low wattage thought capacity of a tabbyatgmail or are you on Tiny 95?

Come to think of it with a maximum of 2GB=ram capacity and frequent defrags you'd do alright on a PIII or even better on an Athlon with relatively low power consumption.

Well done especially if you are on a Tiny version

You can sneer but the richest south American country or rather the one with the largest oil reserves on the planet can't make the budget balance. I believe this is due to the CIA trying to get its hands on the oil. Or at least I would Alex Jones that explanation over anything more simple.

It's not the case that the more body mass you have, the more you can
"utilise it" unless you plan to roll down a hill, or jump off a cliff;
the higher the mass, the more energy you'll need to provide to rock back
and forth.

That's because they have set their budget based on high oil prices. And

Amazing what you can find on Youtube;}.

Not the part that i was referring to but in this clip 78 pedalling to
run an electric shower so assume thats 10 kW

So a 2.5 watt electric kettle a quarter of that so 78 dived by 4 is 19.5
so say 20 persons?....

ITYM 200Whr = 0.2kWhr which is a measure of energy.

200W is also about the energy consumption of a human at rest. You can do
about that much work but anything beyond about 100W work output is hard
to sustain for an extended period unless you are an athelete.

We had a static bike connected to a dynamo with a choice of no load, 60W
incandescent or CFL 60W equivalent as a demo. Most people were horrified
at how hard it was to drive the mere 60W lightbulb load. It spent a lot
of time glowing rather dimly when in circuit. A couple of keen cyclists
used to working out on spinners could do it OK but mere mortals were out
of breath before the 2 minutes was up.

It was very instructive to switch to the low energy light bulb. Most
people could power that reasonably well without getting out of breath.

Everyone could do it with no load at all.

Quite. ;-)

The thing is, only people who have no real clue will confuse someone
offering real-world-facts with anything else.

When I was regularly driving my electric Moke about you would get the
odd person who came up with the 'unique' idea of 'having a dynamo
running off one of the tyres, charging it up as you drove along' ...
or a paddle wheel connected to a dynamo charging up the battery in
your electric outboard boat. I mean it's nice they tried to think
about such things but a shame that the didn't understand the basics
(including 'perpetual motion'). ;-)

I was in Dads workshop yesterday and came across the hand driven
version of a 'heavy drill'. I think it had a shoulder rest on the end
like a stock on an assault rifle and was much bigger than yer typical
'hand drill'.

others who have never used a decent sharp handsaw don't realise
how quick they can be.

Absolutely, including hacksaws cutting stuff like stainless steel
bolts.

I salvaged a load of battens from a shed the other day and cut them
all up into shorter lengths for another project for my Mums garden. A
pair of saw horses and a nice sharp fine toothed panel saw had each
cut done in just a few strokes (in fact I had to 'ease off' or I'd
have cut them through too fast). ;-)

A dustpan and brush can still be very useful.
