Bwahahahahahaha! Thanks, Win! I needed that laugh. But I have to ask... where did you get that cockamamie idea about donors? Righties are floating in money and lefties are trying to take it. If you're drawing all your conclusions from the McCain campaign... he deserves to lose. ...Jim Thompson -- | James E.Thompson, P.E. | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona Voice:(480)460-2350 | | | E-mail Address at Website Fax:(480)460-2142 | Brass Rat | | http://www.analog-innovations.com | 1962 | America: Land of the Free, Because of the Brave

The sad, but talented, Jim. Blinkered, He Be, like that Carlin bloke said "Everyone who drives faster than you do is a maniac, and everyone who drives slower than you do is an idiot." That is Jim :( Martin

How about we all go nuclear and run about on electric trains. I heard fusion power is getting there as well. Sooner or later there will be no oil. It's nothing to do with being green, just finding what to do when we run out. Of course the US will go on invading countries that have oil reserves but even that has to end at some point.

Much of the energy required for acceleration is recoverable upon deceleration via regenerative braking. It's just a question of efficiency. The inevitable losses are friction and air resistance, primarily the latter, especially at high speeds. For stop-start urban driving, failure to recover kinetic energy upon deceleration (i.e. lack of regenerative braking) is a significant efficiency loss. Realistically, we aren't going to see electric vehicles becoming widespread until battery (or equivalent energy storage) technology improves. Taxis and buses are a different matter. For heavy use in an urban environment, the efficiency gain from regenerative braking could make it worthwhile developing the necessary infrastructure (i.e. places where you can swap flat batteries for fully charged ones every couple of hours). |
