![]() "Dave" wrote in message oups.com... The recent discussion of the merits of various electric cars. I'd summarize the current state of the art as one of interesting technologial developments, but an unsolved basic problem: How to store an adequate amount of the source of motive power in a manageable package. Batteries aren't there yet - and may never be. NEVs are a joke, and the 3-wheel "motorcycle" types are marginal at best. Now it appears that someone has come up with the idea of running a vehicle on compressed air. Check this out: http://www.theaircar.com/ There is nothing novel about the technology - air motors have been around for years. They are often used where sources of ignition are a hazard. The only thing new is the idea of combining an air motor and a source of supply in a compact vehicle. The advantages would appear to be adequate power and range for urban/suburban use - and zero pollution (not counting the pollution generated in the process of compressing the air in the first place). Such vehicles could be "recharged" by compressors overnight - when surplus electric power is available. Downsides? High pressure compressors are expensive, and require lots of power to operate. Not to mention the fact that any high pressure tank is a potential bomb. OTOH such tanks are in common use, such as SCUBA tanks and paintball tanks - found everywhere. Comments? David Johnson Maybe supply the pressure from a chemical reaction (alka-seltzer and water; vinegar and soda, mentos and coke, etc.) You won't need the high pressure if you can renew the pressure while you are driving. -- *H. Allen Smith* WACO - We are all here, because we are not all there. |

I was thinking about some substance that could be used that a small amount of matter when reacted would produce a large amount of "controllable" gas. Forget about plugging it in each night, just drop in a cartridge or something. (Hey I'm just an idea man - you work out the details) -- *H.

Carbide produced Acetylene. I wouldn;'t care to try and run a IC engine on acetylene! I have used it in lamps however and the light they produce is brilliant! Bertie |

Vernors works better than Coke with Mentos - more carbonation. Diet is better than "regular" - not as sticky. Besides, Mentos and Coke is not a chemical reaction. It is a physical one. It so happens that Mentos have a large surface area that is exactly the right texture to allow CO2 bubbles to form on it. You could make a ceramic Mento that would have exactly the same effect as long as the surface was the same texture as the real Mento. A ceramic Mento could be used over and over. -- Waddling Eagle World Famous Flight Instructor |
