My friends, we are witnessing an industry revolution in the making. Most likely, oil prices will not retreat to the level of sub-$2 gallon. As a result, the evolution in automotive technology will keep progressing. And it is a welcome change considering that the internal combustion engine has been around for over 150 years (with relatively minor modifications

Hydrogen is a distraction. It is a storage form for energy, and not a particularly good one (takes up too much volume and needs to be highly pressurized). To produce hydrogen in large quantities, one could run an electric current through water to produce hydrogen and oxygen gas. If so, why not just store the electricity directly in a battery, which

Definitely agree there. Ultimately, all energy on Earth is derived from the sun (well, actually some geothermal sources as well). Why not convert solar/geothermal energy to electricity directly and bypass having to grow corn and such nonsense (which take up additional energy). From a thermodynamics perspective, Sunlight -> Electricity is more efficient

From Wikipedia: It is disputed whether corn ethanol as an automotive fuel results in a net energy gain or loss. As reported in "The Energy Balance of Corn Ethanol: an Update," the energy returned on energy invested (EROEI) for ethanol made from corn in the U.S. is 1.34 (it yields 34% more energy than it takes to produce it). Input energy includes
