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. - Brad Guth -

Terrific 'energy density' doesn't affect the total amount of energy required to move a Hummer you ignorant fathead. The energy needed to propel a Hummer will never be in the '100 mpg' region because of fundamental laws of physics, notably those relating to drag. Graham

However, add quality silicon > enhanced tires, Bollocks. No such thing. You're just making stuff up. Besides, the rolling resistance is a small proportion of the total drag. You could of course fit SOLID wheels but the ride would be a bit harsh ! > 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. That will not affect the energy required. So your 100 mpg claim is quite simply barking mad. Graham
