"Steve B" wrote in message ... http://www.youtube.com/watch?v=8Dv-gl6RCGc They had a special on a while back on Jay Leno's vehicles. One was a motorcycle with a helicopter turbine engine. They were discussing it, and Jay said the big drawback was there was a 1-2 second throttle lag. You turned the throttle on, and it was 1-2 seconds before it kicked in. You shut off the throttle, and there was a 1-2 second delay until deceleration. He said he rode it, but it was scary. When asked top speed, he quoted the top RPM of the turbine, but said that no one who had ever ridden it anywhere would take it anywhere near that high speed. This car would have the same problems, and would have to be driven on wide open straight areas with little turning, stopping, or starting. But it is unusual, and very interesting that some metal worker geek put it all together with state of the art elements from his era. Quite a car. Steve |

We use them to scare New York beach tourists away. We call the crane flies "Jersey skeeters." We know they don't bite. We just don't want the people from Long Island and Westchester to know. We even tell them that if they get bitten, they'll need to get to the hospital for an emergency transfusion. d8-) And the real mosquitos here are high-quality birds, capable of raising havoc at any outdoors event. But this is the thing we're proudest of. We have, not 61, not 62, but 63 different species of mosquitos in New Jersey!

I think that Rutgers Agricultural Extension Service cross-breeds them for toughness and resistance to toxic waste. d8-) thank god and knock on wood we don't have blackflies here in s.e. new york state, or at least like they have in NH. many years ago i went on a fishing trip with my brothers to NH. never experienced this before. i opened the car door, stepped out and within 2 or 3 seconds was swarmed with blackflies. they were in my eyes, up my nose, in my ears and down my throat. was gagging on swallowed blackflies. in my entire life up to that point i never had to use one of those hat-net things, they were an absolute necessity there, was fumbling with it trying to put it on as fast as possible. if the net got a fold in it and touched your skin they'd find it and be biting you there, was incredible. they were biting me all over. i was in a mild state of panic thinking "jeez, if you were stranded in the wilderness with these bugs they could KILL you!" i mean, either directly or indirectly, like you'd starve to death or die of dehydration constantly swatting them off of yourself. maybe we just happened to step into some localized concentration of 'em, but if it's like that all over in NH i'd want to shoot myself if i lived there. can't imagine what it would be like to enter a cloud of 'em like they have in alaska (saw it in a movie). b.w. Yes, blackflies are God's reminder that we're not really necessary to the continuance of the planet, and that he might decide to dispense with us at any time. They are the Harpies from Hell. The soul of Satan resides inside of each one. They are vile, ugly, and mean...but don't get me started. g My dad went fishing in upper Quebec province once upon a time, without headgear, and when he got home his head looked like a pumpkin that had been shot with a few loads of birdshot. And he was born in NH and should have known better. I'll never forget it, and I was four years old at the time. -- Ed Huntress |

So the problems attendant on internal combustion (high pressure and temperature chemistry) aren't there.

They had the suspension of a horse-drawn wagon. Stanley Steamers were a neat car! I had a ride in one once. I got to drive a friend's several years ago. What a hoot! You needed three hands to work all the controls to signal, slow down & make a turn. No "vroom", just "chuf chuf chuf" as you accelerated. Doug White |

: snip The burner and stoker (for solid fuels) and the control systems are the big bugaboo that will take some serious work. Triple expansion motors and Condensers are easy, but getting the cylinder oil out of the water before you feed it back to the boiler it is always a challenge. Modernizing the controls and sensors so it can run automatically and unattended isn't bad, they have continued building steam boilers - you just have to miniaturize control gear built for a 100MW power plant down to the proper size to work on a car. To modernize the handling of solid fuel, you'll need a little robot with a shovel, who sings "16 Tons" while he's stoking the boiler. Why not base it on pellet stove technology? A friend of mine uses a pellet stove for heat. He has a big hopper in the garage labeled "Purina Stove Chow". Doug White |

Eh, it's possible, but you'd need a big hopper -- maybe you'd want to tow a tender. g Its energy density is roughly 1/3 that of gasoline, per unit weight; energy density per unit volume is slightly better. So a 55-gallon hopper would be equal to a 20-gallon gas tank, not including the screw or other feed mechanism. A friend of mine uses a pellet stove for heat. He has a big hopper in the garage labeled "Purina Stove Chow". Can he put wheels on it? He might get across the state line with that. g Steam engines without recuperators and other complexities aren't very efficient to begin with. And starting up in the morning would be a bit...er, slow. However, they're fun to think about. -- Ed Huntress |

Capture and loose 10 of each (or 1000) and loose them in
the capitol buildings there - might shake them up! Martin snip wow, 63 species. i figured there were maybe 3 species. Impressive, huh? We don't fool around here. I think that Rutgers Agricultural Extension Service cross-breeds them for toughness and resistance to toxic waste. d8-) |

A Lycoming or Continental where I don't have to worry about an "Oh, ****..." moment. And the instrrument panel is past sparse, and bordering on "guess" - No compass, no electrical at all, no nav lights, no transponder, no radio... A Piper Cub, a Grumman Goose, maybe a Huey. But that's as far back as I'm going to hop in - while conscious. You'll have to A-Team me. And NO Ospreys, them things are death-traps. -- Bruce -- |

More people have been killed in Teddy Kennedy's car than have been killed by civilian nuclear power accidents in the USA. Amen! There have been a few recorded deaths (though they were hushed up for many years) in the 'Military and Experimental" category of nuclear power generation, but none in the civilian realm. Chernobyl had no containment building, just a 'warehouse'. Three Mile Island stayed contained - Barely. But "almost" only counts in Horseshoes and Chicago Pineapples. -- Bruce -- |

Let the Record show that Lewis Hartswick on
