I'd be interested in details of such a bus being used in Chicago. The longest range that any manufacturer today can get out of an "inertia" bus is under 10 miles. They basically have to wind up at every stop. >

No car can work without a flywheel and clutch.except an electric car or train where its heavy rotor becomes its flywheel. TreBert

At least two thirds of the energy used to power Cable/Sat/DVR set-tops (200mil+) is WASTED. On.. but nobody is watching/listening/recording.. Another large chunk of electrical usage is being consumed by Energy hog(400 to 600watt) Plasma TV's. Large Flouresent bakclight HI-def TV's aren't much better(180 to 340 watt). Fixing those two issues (simple solutions actually) would save enough energy to propel most of the US's passenger/personal transportation via EV's..

Yes, but the performances are very different than current US vehicles fleet (not I live there nor I'm interested in it), if you don't want to do an orange and apples comparison these are the right numbers indeed, it' s very difficult to go down to less than 15 kWh per 100 kWh and even something near 20 kWh per 100 km is a more reasonable figure >>personal transportation is more than 3 billions miles per year, > > Electric bikes are even better.. Less than 0.7 kWh per 100km. > Wayyy cheaper too.. That's right, but it's an other orange and apples comparison, the performaces of the two kinds of transportation are quite different. By the way that' s why I included the very efficient electrification of collective transportation >>http://www.fhwa.dot.gov/ohim/tvtw/10febtvt/figure1.cfm >>they will need more than 900 TWh/year of electricity, or the total nuclear >>electricity US production.

Perfectly agree here > At least two thirds of the energy used to power Cable/Sat/DVR set-tops > (200mil+) is WASTED. On.. but nobody is > watching/listening/recording.. It's irrelevant, the total amount is very tiny in any industrial economy. Rather, there are huge potential of energy savings in the industrial sector, particurally in high efficiency electric motors plus inverters |
