On energy density and nuclear power
Two words: Energy density. Nuclear power is currently the only technology which has the energy density to replace oil, gas, coal and so forth. We could put solar panels on every patch of barren ground, windmills in every windy pass in America, biofuel rapeseed on every piece of marginal ground not needed to raise timber or food, and still fall woefully short even of the energy requirements of modern agriculture, which is a very energy-intensive process that requires hauling enormous amounts of food long distances over a transportation infrastructure that requires enormous sums of energy to operate even if we transition it all to electrical or hydrogen operation. And without modern agriculture, we have a great die-off, because we now have far more people on this planet than can be supported by primitive agriculture.
Frankly, I prefer being alive to being dead. I've looked at some of the modern nuclear reactor designs, and they're far safer than Three Mile Island (which itself was far safer than Chernobyl, a weapons reactor converted to civilian use which would have never been permitted to operate in the United States). Note that the so-called "hydrogen economy" is basically a mechanism for storing nuclear power in an energy-dense manner for individual transportation, rather than a method of generating energy... the only method for generating energy is nuclear power, whether it is the nuclear power of the sun (which also powers the wind as well as solar cells and plants), or nuclear power from man-made reactors. Even oil, gas, or coal is just nuclear power in the end, since it is just stored nuclear energy from the sun, energy stored in hydrocarbon bonds rather than in batteries...

Day before yesterday, gas was $3.01 per gallon here. Last night, it was $3.05 per gallon. I hate to see what it'll be tonight.
I wouldn't mind so much if all these billions were going into some fund to create an alternative to oil. But they aren't. The oilmen are raking it in and piling it up. Which goes to show that oil and the open market don't work once we're past peak oil, which we probably are.
If there was someone making, say, widgets, and piling in billions in profits, someone else would start making widgets too. But ain't nobody makin' no more oil. What we've got, is what we've got. And the alternative energy guys still aren't getting enough money to come up with some viable alternative to oil. It'd be easy enough to do -- just whack an oil windfall profits tax on the oil companies. But it ain't happenin'.
Gotta go, gotta get dressed in all my motorcycle duds to get 50+mpg on my morning commute...
