    Solar energy is just so danged dependent on so many variable though. If its either, cloudy, rainy, AT NIGHT or anything else to hinder solar radiation, solar technology fails with flying colors. I do agree, solar is a viable energy source, but its near impossible to use now, because current solar tech is only like 30% efficient if you're lucky.

    WHat if you live in Sweden or something, where you only get 5 hours of daylight in the winter. Ugh.

    Or in the arctic circle? For six months it would be great. The other six, bleh.

    Stirling engines would definitely be the future, if cheap energy was at all a priority. They just need a heat differential, whether solar, water, or whatever. They can even be run in colder conditions, so long as the gaseous properties are in balance. There is a lot of work that needs to be done on them, but at present they can even be used to convert otherwise "lost" energy (heat) into useful energy.

    Anyway, this will probably never happen in a world where money dominates. However ineffective coal, fossil fuel, or any other source of non-renewable energy is, it is still highly profitable.

    I don't think clouds will be an issue for solar power once panels become highly efficient. The problem we will have is storing the power, we need better batteries. Solar power should be able to give a surplus given a good day of sunlight. If we can store it efficiently, a few days of cloud cover shouldn't hinder power supplies. Maybe the answer is to use solar power to make hydrogen fuel from water and then somehow store that.

    There is lots of free energy for the taking. Turning off the AC and sweating yields free electricity, while turning down the heat and wearing a sweater yields free electricity/gas/oil every winter. We can get more free energy by building smaller houses and driving less. No new laws of physics are necessary.

    Uhhh wouldn't that just be less energy used?

    too funny.... I was playing with my Stirling engine earlier today, all you need is a 5f temp differential on some of the more efficient models..

    it amazes my new students when they see an engine running with no obvious form of internal combustion or electric motors... I tell them its "FM" (freakin magic)

    but IMHO it will be at the Quantum level, prob Quantum Chromodynamics where we will find our energy in the future

    just don't ask me to explain it LOL, but there is no "creating" energy, all that will ever be is already out there... all we can hope to do is to efficiently convert it into useful forms without destroying ourselves in the process...

    now my brain hurtz
