Charles It's a great show

But there are globally unpublished solutions also, unfortunately video is not in English language. Still it's worth going through.

Styling vs. Drive method

I am always interested in the paradigm between the actual drive system, and the external style of the body.  Of course the two things do not necessarily have any interrelation, although smart design would attempt to integrate external styling features and lines to somehow augment the basic functional drive system.  For example, why are future concept cars always covering the rear wheels?

That being said though, this isn't really for us. It's for our grandkids....the future. It needs to be done and I am glad it is.

Right on Charles, not only can you not afford them, but why would you want them at this piont anyway. I could count the ways why not, but I won't. I think they speak for them selves.

I'm with you on that, Cadman-LT. Can't afford any of these.

CNG / Gas is out there...

Naperlou,William K,

There are numerous fleets in US running with CNG/Gas. Nearly all are conversions (I think City of Phoenix is doing this with some of their cars and trucks still) . In years past, I have been involved in some conversions. And we have to send sample cars to National testing sites (only two remaining in US) generally used by the auto manufacturers for EPA approval. Biggest issue with GNG is the size of the tanks vs range. GNG is not that great on storage volume vs energy stored. I don't think California's requirements in this area are significantly harder for us to meet.

Often overlooked, nice feature of CNG.. If you have natural gas at home, you can have a filling station at home.

I am also involved in Liquid Propane conversions (taxis in Las Vegas). Constantly having to come up with new conversion designs (Nevada law requires retirement of a chassis used for taxi service after five years - regardless of mileage). In this case, that means there are about 150 taxis in Vegas being retired (1/5th of one fleet from the one company) each year. This also means they are buying 150 new replacements (often from different car companies) requiring LP conversion - and EPA approval - each year.

Only because:

-They buy LP in large quantities ( 6+ milliion gallons/ year?)

- with large variations in quality (octane rating) aka "the cheap stuff"

- shipped in via railroad cars from Texas,

- to get it priced for about 1/2 the price of gas..

Does it make sense to reinvent/re-engineer a solution each year for 150 cars.

And it is not a simple engineering solution (variations in fuel quality vs EPA requirements vs driveability vs maintenance costs).. with cars ranging from Ford Crown Victorias (V8s), Ford Escapes and Toyota Scions (4 cylinder).

Just one of many projects (in numerous industries) I do each year.

I am replying here because, unfortunately, the system wouldn't let me post a new item. Please forgive this indiscretion.

I am glad to see fuel cells finally being included in the mix of electric vehicles. I was involved in the 1977/78 alternative fuel initiative while in college. We didn't go that route, though we went with hydrides to provide the hydrogen for a smaller engine that could be used for an alternative, and more efficient solution.

We learned a lot. Both from the what not to do, and from what makes the best sense.

We went with hydraulic motors on a Horizon chassis. The power came from a properly optimized IC engine operating almost, but not continuously, to the charging system for the motor. Braking was done by extracting pressure from the wheel motors. When stopped, when pressure was established again, the motor went into a halt condition.

It worked very well using an 8080 processor for the entire system.

I was the computer guy and I learned a lot from the mechanical guys about what was going on. I still think that idea is possible. Nobody is actually attempting it and I wonder why.

Nice article Charles. They still have a long way to go before I get one though.

I believe you're right, Battar. Compression ignition is efficient, and diesel fuel inherently offers more energy. So, yes, diesel use will definitely grow in this country. Every barrel of crude will always have a certain percentage of short-chain hydocarbons in it, though, so gasoline won't go away any time soon.
