Hey! What time is it in Isreal? No body else seems to be here but you and me. It is 4:48 AM in the East coast of the United States, here.
Yikes! No external links or references on that page. I'm not so much into the EPA either.Yonoz said:Indulge yourself: http://www.epa.gov/ttn/atw/allabout.html" .

Kenneth Mann said:I was careful to say "a" solution, because the applicability of the electric car is obviously quantity limited --- but it will relieve us of a tiny portion of our petroleum dependence and the attendant pollution
They have been replaced by hydrolic hybrids.Chi Meson said:Whatever happened to flywheel systems? Seems that ten years ago we were just about to have these great flywheel enenrgy recovery systems for busses and delivery vans etc. They seemed to have disappeared. WHere are they now?
chroot said:You know what would be a real solution? One that could be implemented today, for essentially no investment? I do. People need to stop driving their cars altogether, or reduce the use of their automobiles to sensible levels, reserved for tasks that really require such a machine. Americans use cars for ridiculous purposes -- driving a mile down the road to pick up a movie, for example. Or sitting in traffic to drive a whopping six miles from home to work. If people simply drove their conventional cars half as often and rode a bike or went rollerblading instead, it would cause an instantaneous, dramatic decrease in petroleum dependency, pollution, consumer debt, and even average waistline -- all of which are enormous, inter-related problems faced by our modern societies.
chroot said:Honestly, if you think buying a $100,000 electric car and sitting in the same six miles of gridlocked traffic every morning somehow makes you "part of the solution," in my opinion at least, you're an idiot.

Kenneth Mann said:What is wrong with this idea, is the fact that like communal living it will simply never happen (unless we go into a depression, and I don't think most people will find that preferable)!
The best solution must always derive from among those that are realizable --- not those that are merely idealizable. People will resist taking two hours each to get to and from work, when it can be done in thirty minutes or less.
Human nature will always get in the way of implementing anyone's "perfect solution" ideas, including those advocated above --- so why not just once try compromising with reality.
The actual target price for the car is $40,000 --- not too different from that of today's guzzlebuggies.
Finally, there is no honor or intelligence in resorting to name-calling. By the way --- that would make all those who get caught in traffic Today idiots.
Are you that much superior to the rest of the world's mere mortals?
The results are in . . .
Although fuel savings may vary by vehicle and speed
range, a national trucking association estimates that
a combination truck driving 55 miles per hour uses up
to 20 percent less fuel than a similar truck driving 65
miles per hour.
http://www.eia.doe.gov/bookshelf/brochures/diesel/dieselprices2006.htmlNearly all semi-trucks, delivery vehicles, buses, trains, ships, boats and barges, farm, construction, and military vehicles and equipment have diesel engines. In 2005, diesel fuel accounted for about 15 percent of total refined petroleum products and 75 percent of the total distillate consumed in the United States. On-highway motor vehicles use about 80 percent of total diesel fuel, with off-highway vehicles, construction and farming equipment and diesel-electric generators consuming the rest.1
