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. > You may want to check out using supercapacitors instead, as a temporary > energy storage mechanism, 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. > since they have a very high power rating (in the > range of 1000x batteries) due to not being based on a chemical reaction. > additionally, supercapacitors don't need additional plumbing and don't need > water refills. they also can skip the big energy loss of > internal-combustion engines which are usually less than 50% efficient. Funny you should mention that. Google 6 stroke engine wikipedia https://www.youtube.com/watch?v=IovhYvKpFRQ 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.

Funnily enough, the Intel building in Costa Rica happens to be empty at the moment... :) L. -- --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68 _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
