Re: Ethanol

ALL major industrial high thermal heat, beat and treat processes ALREADY use electrical furnaces because those are the most efficient for processing and manufacturing metals and their alloys. So ALL of heavy industry, except for back up generators than can run on ethanol, can be powered by ELECTRICITY.
I think that is a real "killer app" for kickstarting demand, making ethanol-powered ICE electrical generators.  It's something that can be done today by someone with good engineering skills (or enough money they can hire someone with such skills).  Alas, I have neither the skills nor the money.  But one thing that makes ethanol ideal for back-up generators is that the fuel can be stored indefinitely without special processing; even with additives gasoline can only last a couple years in storage.  (Propane itself does not degrade with storage, but the seals do, so you can find your tanks empty even though you never used them.)

I suspect that Brazil my have some generator models that run exclusively on ethanol. They already require their filling stations to have at  last one E100 (100% ethanol - illegal in the USA - LOL!) pump. So if they have a large percentage of cars running on it, it's not a big step to rig up a car engine to run on ethanol.


I'll check around when I get some time. To me, the ultimate poison pill  ;D or the fossil fuel industry in the USA would be a legal internal combustion engine made with alloys that cannot handle high temperatures (i.e. VERY cheap to manufacture due to less tempering required and also because it requires 30% LESS metal -  weighing at least 30% less). Any gasoline use would warp the block and/or the heads. So, they would have to be placarded with the "ETHANOL (E!00) ONLY" warning stating that any use of gasoline voids the warrantee.

The same thing applies to natural gas or LPG. LPG and Methane burn cleaner than gasoline but the waste heat problem, while not being as bad, still requires high heat handling alloys and over engineering we have in ALL our fossil fuel powered internal combustion engines today.

Of course the USA will be the last to allow such an ethanol only engine  across the border. The feds will arrest you for carrying "non-fuel grade" fuel (i.e. if you can drink your fuel, Lord Lucifer and the Fossil Fuel Government will frown on you with extreme prejudice :evil4:).

The fossil fuelers will never admit that the waste heat of fossil fuels, so necessary for them to claim they have a "higher energy density" than ethanol, is useless for obtaining mechanical WORK from an engine AND SUBTRACTS from engine power BECAUSE some of the engine energy must be used to COOL the engine.

Hess's Law of enthalpy of formation, the one Charles Hall adores and the one used for just about ALL of the assumptions on laws of thermodynamics in science today, classifies ALL heat, whether waste heat or not, as ENERGY. This is true. But if you can't use some of that energy to do work, and if that energy you can't use actually INTERFERES with you doing work (i.e. SUCKS ENERGY from the energy that is useful in order to keep the engine from over heating), then basing ERoEI on Hess's Law is thoroughly misleading.

Finally, Hess's Law is not used as it should be to subtract the energy required to bio-remediate the damage that pollution products from fossil fuels cause. Externalizing those costs as if they did not require an energy input to assure a viable biosphere is an insult to the laws of thermodynamics. It's fossil fuel industry cherry picking, not science.
