Got really nice team this time. Been planning for about 12 years.

And (surpriise) the processor will end up in the lithium battery packs, and
so will an EOMA68 Card

Correct! Bill Ross is the inventor of exactly that. He uses Potassium
Hydroxide as a catalyst, and nickel plates with 0.004 in clearance, 2.5v @
50 A and you get enough hydrogen to add to a family sized car.

No, because the voltage varies with current, naking it extremely difficult,
electronically, to deliver the power back.

What the supercapacitors *are* good for is fronting on the batteey packs,
directly at the controller.

The decreased resistance results in power being first delivered *from the
capacitor* which protects the battery from high load.

Funny you should mention that. Google 6 stroke engine wikipedia


Patents from 1880 and 1921 show that water flashing to steam when injected
at TDC will not only cool the cylinder but will actually do "work".

As efficiency is a direct product of temperature differentials, the 2 extra
strokes can result in a whopping FORTY PERCENT efficiency improvement.

The processor and EOMA68 have been part of a long term strategy that is

Of course.

Yeh we need extra (motivated) people.

Funnily enough, the Intel building in Costa Rica happens to be empty at the
moment... :)
