Thanks for those honest enough numbers, even though a sustained 70 mph
wasn't exactly within my agenda. However, add quality silicon
enhanced tires, give that nasty aerobraking brick of a Hummer a high
energy density battery/fuel-cell, feed that fuel-cell h2o2 and give
that little one-cycle efficient engine its fluids of h2o2 plus
whatever fossil derived fuel (such as common diesel road fuel or low
sulphur heating oil) for accommodating our little but powerful ICE,
and say it again, KT.

Obviously a relatively small but powerful fuel-cell like battery of
h2o2/aluminum is offering terrific energy density, as being currently
doable as is.

The use of h2o2 along with whatever fossil fuel that's in liquid form
(including most biofuels), on behalf of feeding a given one-cycle IC
engine, is also doable as is.

The combination of feeding h2o2 into the compact fuel-cell/battery or
stored electron providing unit, along with feeding the dual injected
little ceramic radial turbine engine that's offering a one-cycle
internal combustion efficient alternative to the otherwise pathetic
four-cycle IC engine that's so mechanically and thermaldynamically
inefficient, whereas instead my hybrid alternative with its nifty one-
cycle and mostly ceramic little IC engine that's rather powerful for
its size will create the absolute minimal CO2 and zero NOx, with more
than sufficient energy to spare, which is also perfectly doable as is.

The GM Volt for example could achieve a relatively good deal of
driving performance and provide that safe 4X passenger car as capable
of offering a sustained city driving or semi-local commute worthy of
200 empg per fossil gallon of fuel, and that's no lie.

The likes of Warren Buffett, William Mook and myself will gladly take
care of supplying all the spare/surplus capacity of clean renewable
energy for creating such nifty products of stored energy, as well as
for boosting our nations's outdated and badly overloaded power grid,
or on behalf whatever local applications you'd see fit to invest or
waste such energy upon, and trust that this too is no lie, as being
currently doable as is.

Of course as of 50+ years ago perhaps not, but we could and should
have been deep into the R&D and consumer applications of accomplishing
all of this as of a couple of decades ago, because it's all old
physics and of the kind of proven science (much of which derived from
smart Yids) that's replicated to death as of before then.
