<div><br></div>While I agree that it might be based on bad driving habits, and that it would be more efficient for people to drive better- it doesn't subtract from that fact that many people do have bad driving habits. Thus the technology may be appropriate for retail to the general public. <div>

</div>It has some potential. Solar cars in the North American rayces use<br>
regenerative braking in their systems since there are enough starts,<br>
stops, hills and speed limits that make it worthwhile. The Australian<br>
rayce doesn't need it since there is one traffic light in the 3000 km<br>
course route between Darwin and Adelaide, in Alice Springs, and there<br>
are very few hills of any note, so the regenerative braking parts are<br>
extra weight and complexity that work against the efficiency of a solar<br>
car.<br>

</div>Danish transplant to Australia adventurer Hans Tholstrup did many tests<br>
of this theory including circumnavigation of the continent of Australia<br>
and managed to demonstrate that driver behaviour had a very significant<br>
effect on energy economy and pollution.<br>

<br>
</div>I mostly agree with you, but I do see some use.<br>
<br>
I recall an article in IEEE Spectrum about 20 years ago about an<br>
electro-mechanical battery consisting of a carbon-fibre flywheel running<br>
on magnetic bearings in a vacuum at a speed of several hundred thousand<br>
RPM. There were two clamped together to avoid gyroscopic effects. The<br>
reason for the carbon fibre and high rotational speed is to get the<br>
energy density up with total mass down. I probably still have the<br>
article here somewhere...<br>
