Besides technologies that work, and other that doesn't, and others thar are only believed in by anti-thermodynamics illiterates as the "water motor", it's true nearly all of them are sold to the people by mass media and most of the times by their own press releases as the sacred fountain of hidden energy, able to provide enough energy to the whole world for centuries with only a pair of grams/ounces of matter or a brief exposition to sun.
Ok, we are aware that anti-matter generators achieve that, but are still centuries from actual use for a extended power grid. But thing is cientifics, universities and companies which release these press releases are more focused on attract attention than provide a true cientific paper to discuss, often forgetting things as the building and manteinance cost, the actual efficiency (nearly all needs some form of energy input, directly or to its input matter), etc.
Don't blame nuclear facilities for their hide disadventage, the centuries-actived waste, and then ask for solar panels which only last for ten years in the best case, or electric cars with batteries to build which you have to use more energy than they can storage for their whole life-cycle.
Dogbert is right, we must focus on find new ways of generate electricity, especially you oil-hungry americans, but to believe in every insane or lier with a white coat asking for the whole country's GDP to release his "invention".
@Sluggeaux Take your own words and do some research. Your data seems to be massively outdated, and if applies only to the first generation solar panels. Industry standard is ~10% in 25 years. Quality manufactures cover that in their guarantee.
you talk of degradation of photovoltaic cells. my comments are primarily directed to mirrors focusing the sun on a collection tower to generate heat. capitalism is not up to dropping one technology (nuclear) while the holders of capital believe that there are few more golden pennies to be drained from it. corporations have devolved to machines utterly indifferent to the welfare of people or their nations. short term profit is the religion. this religion offers no salvation.
