Ken & Neil - mega-educational replies. Thank you. Ken - best of luck with the e-car co.

A flaw in my initial, hypothetical argument of centralizing oil-2-energy production in order to provide electricity for EV travel @ 95% thermal efficiency vs. 300 million or so mobile power plants (in varying states of disrepair), converting O-2-E @ 25% efficiency, is this:

There would still be an ICE step in the process.

Otherwise, how would you convert gas to amps? Granted, central power production might make solving the efficiency problem less of a challenge than streamlining energy production for 300 million little ICE power plants, but...?

I'm no engineer, but steam is the future:

The thing about electricity is that it *can* be made in many ways that are renewable -- and that are decentralized and local. A renewable source nearby is virtually carbon free; and as time goes on when we make the next generation of renewable energy system *with* renewable power from the first generation -- then it will have a minuscule carbon footprint.

By the way, I have a efficient electric car design, called CarBEN EV that is open source -- it seats 5 people (3 of them can be 6'-4"+) and it can fit up to a 54kWh lithium pack in the floor. If it is as aerodynamic as I think it is, it may well get below 125Wh/mile, for a very nice range up to~ 400 miles:

If you want me to email you the SkethUp 3D computer model and / or the CAD drawings, I'd be happy to! I'm hoping to start a 1/5th scale model later this week with craft plywood, wire, and fiberglass.

Sincerely, Neil

I thought I had already posted this a while back, but...

For anyone working on a body-from-scratch project, (like yours Neil) please
feel free to contact me about using the stitch-and-glue process (which is
more commonly used to build boats, another of my passions). My boatbuilding
site is www.hoochboats.com. (It sounds like that's the process you have in
mind, Neil.)

I offer a boatbuilding class in which we build the Bon Temps (a modified
Pirogue) and the finished boat is about half the weight of a production
kayak (25 lb. vs over 50 lb.). I recently finished a custom-designed 12'
kayoo (half way between a kayak and canoe) which came out at 19.9 lb. The
structure was slightly more sophisticated that the pirogue structure. Wood
is a great material for stong, light, structures -- you need to get pretty
sohisticated in the composites hierarchy before you can beat it -- and it is
pleasent to work with.

The Hispana Suiza Tulipwood car made an impression on me when I was a kid.
