I've posted such numbers dozens of times, and your PC or MAC can
otherwise search for and thus uncover all the fancy numbers you'd care
to review. However, from time to time I'll edit and thereby revise
upon a given application.

OK, refresh my memory: if we convert aluminum oxide to metallic
aluminum by electrolytic smelting, and convert the aluminum back to
electricity in a Al-H2O2 battery, what's the net efficiency?

And for each KWH of delivered energy, how much H2O2 do we need, how
much did it cost, and how much energy did it take to make it?



What is it about the clean and renewable 40 kw/m2 of a given tower
footprint of solar and wind derived energy do you not understand?

Tower footprints can be arbitrarily small; it's what's hung on the top
of the tower that costs.


If not for the makings of h2o2 and aluminum, what else would you smart
folks do with a spare teraWatt of energy?

Energy is not measured in terawatts. And I'm not aware of any "spare"
power of terawatt magnitude. If we had terawatts of clean, cheap
"spare" power, why wouldn't we use it to power the electric grid,
saving a lot of coal and natural gas?


How else would you go about burning coal at it's peak efficiency
without water, at minimal CO2 and without causing NOx?

BTW, here's a wild idea breakthrough:
A piston engine of 4 cycles is about as mechanically inefficient of an
IC enigne as it gets, and the burning of a mostly N2 atmosphere is
every bit as dumbfounded physics on steroids as it gets, and the last
time I'd checked that's no conspiracy theory.

Piston engines haven't changes fundamentally in 100 years, despite
lots of challenges from turbines, Sterling monstrosities, various
weird rotary engines, steam, fuel cells, whatever. That's pretty
impressive. Still pistons, rings, cranks, cams, poppet valves, spark
plugs.
