  1. Yes it is called passive solar, it is the principle basis for earth-ships, solar hot water, solar cookers, etc.

  2. The inefficiency in solar cells is because they convert from one energy form to another, there are always “losses” when you convert from one form of energy to another. Using energy in its original form is always more efficient.

    Solar cell designs are becoming more efficient but will always have limitations.

  3. The cheapest way to make electricity is hydroelectric. Falling water turning turbines. Way WAAAAYYY cheaper than solar cells.

  4. Yes there is. Thermonuclear energy, but the consequences might be catastrophic.

  5. Fossil fuels. Which is why they’re our main energy source.

    But burning them has one extremely nasty side effect (global warming). Which is why we need to drastically reduce our use.

    Efficiency and direct cost isn’t everything. You need to consider the big picture.

    Considering that, we need to develop nuclear, solar, and wind energy; much more of all of them. We have a very big problem to solve.

  6. stirling engines. howstuffworks.com explains what they are and other sites I’ve found tell how to build them cheaply.

    gas, oil or coal fired generating plants all produce cheaper kWh’s than solar cells.

  8. NO there really is not YET.

    Something that will help would be for our Government to support hydrogen powered power plants and cars. Making hydrogen is way easy to do but requires a engine that will not rust because burning home made hydrogen in a engine makes nothing but water.

    So it will never be supported because if you can hook a solar panel to a gallon of watter with a little salt in it (3/4 of the world is free salt water) and make electric. This has been around for over one hundred years but has always been stomped out by the big oil money. They have allowed solar to get to where it is because it was not a hazard to big oil when it started. And really still is not because it can’t be used on a car.
