It has a drag area of about 2.5 sq metres. Its 3 1/2 tons results in a fair bit of rolling
resistance too.
I just calculated the power required to propel it @ 70 mph (the UK national speed limit) as
52kW. That means that 100 miles (at 70 mph) would require 52 x 3600 x 100/70 kJ = 267 MJ
Regular gasoline (per Wikipedia) contains 34.8MJ/litre. A US gallon therefore contains 132 MJ.
So it would only need a 200% efficient engine *** LOL *** to propel this Hummer at 100 mpg (at
70 mph).
Brad Guth doesn't seem to understand the problems about ICE efficiency.

Thanks for those honest enough numbers. However, add quality silicon
enhanced tires, give that brick of a Hummer a high energy density
battery/fuel-cell, feed it and that little one-cycle efficient engine
with h2o2 plus whatever fossil derived fuel (such as common diesel
road fuel) for accommodating the little 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, 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 200 empg per fossil gallon of fuel, and that's
no lie.
The likes of Warren Buffett, William Mook and myself will 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 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 50+ years ago perhaps not, but we could and should have been
into accomplishing all of this as of a couple of decades ago, because
it's all old physics and of the kind of proven science that's
replicated to death as of before then.
