The problem with battery technology is no one wants to pay for it. We have the resources over hear to build, not necessarily better batteries, but hold them to tighter tolerances which in turn make them better. China pumps out thousands and could care less. Look at this forum and see how battery life differs

It''s pretty neat as I am able to hear it and watch the tachometer drop from about 2,250 RPMs to about 1,900 RPMs and settle into a cruising speed. Mine has a "towing" button on the shift lever that turns off the Multi-Displacement - essentially bypassing it and keeping it running on all 8 cylinders, so the additional load while towing doesn't cause it to toggle repeatedly between 4 and 8 cylinders.
The added benefit from a "multi-displacement" processor is that unlike an engine which still has all the additional friction and overhead to move all that additional steel, valves and pistons even when the cylinders are shut down, the processor's deactivated cores will consume nearly NO power during their standby periods. Also unlike an engine which has to take time to rev up, the additional cores on the processor can jump in at "full throttle" in micro-seconds, provide just the boost needed and then shut down again in less time than the human mind can detect.
Divide and conquer!!
As long as we are throwing analogies around, a Brayton cycle motor with reheat would fit in well.
Smart alec!! :D

Would be nice not to have to lug around a laptop, but maybe a tablet and keyboard that I could take advantage of a larger screen and extended battery life.
And then as far as being a laptop replacement, if you really have to use all the horses you probably would be plugged into a power source, anyway. That kind of power in a padphone-type configuration could dominate.
