    The ultimate solar power system:
    A solar panel made of a sheet of mini Fresnel lenses that direct light into a fiber optics fiber. Small lenses an inch or so in diameter would allow a focal length that would fit into a thin panel like conventiinal solar panels. There are lenses that can gather the light from all directions and an additional lense could gather the light into the optical fiber. These fibers would feed into a main cable. The main cable would direct the light at a small array of the new high temperature high efficiency solar cells. The waste heat would drive a heat engine and the waste heat from that would be blown through the hot water heater and house for heat and hot water. An additional bonus would be using this concentrated solar to make methanol from air as is being accomplished in research projects with about one gallon of methanol produced per day from ten square meters of concentrated solar. These concentrated solar panels might cost as little as ten or twenty dollars a square meter and supply all of the world's electricity and fuel at a small fraction of the cost of fossil fuels. With thirty to forty percent efficiency from the solar cells and another twenty to thirty percent from the heat engine, ten percent from the methanol and some percentage from the heat and hot water, such a system miggt aporoach 90 percent efficiency.

    I've been a fan nearly as long as you've had a channel. I admire your initiative and methods. Please continue. One question, if I may. What would happen if you mirror coated the flat side of a Fresnel Lens and used it as a reflective style lens, somewhat along the lines of a parabolic dish? Would it work? I have no idea. I can see a lot of advantages in having a flat, reflective surface that could produce that much heat. Think of the large telescope mirrors that could possibly come from this...etc, etc, etc. I may be (probably am) blowing hot air, but if it works, there would be countless usefull applications. Thank you for reading this and sharing through the last decade.

     2 years ago you still use your 12v Grid-Tie Inverter .
    I have 2 x 100 watt panels which are doing nothing now
    and i would like to get a 12v Grid-Tie Inverter
    but i have no idear what i should be looking for can
    you help me out please gene .....and yes i am from the uk.

    I have a challenge for GreenPowerScience. I have a ram pump circulating water through an evaporative cooling system that gets the temp down to 40 degrees F. I need to make Ice. How can I do that? I Only need to get the temp down another 8 to 10 degrees. I'm thinking possibly using salt somehow. Any ideas? Remember, i'm only using a ram pump with water for a power source and a refrigerant. The system is enclosed in a box for a simple refrigerator. I aim to make the ice inside the box somehow.

    My favorite videos involve solar cooking. I've yet to get the courage up to try it out. =D

    you should put a cap on the bottle with a pinhole and a tiny tesla turbine on top

    Could you take a metal pot, aim it at the side of the pot and have it boil the water (in case of emergency)?
    Any idea on the power output of the focused beam?

    I watched that video when it was first uploaded. I had a different account back then, but used to talk with you via the horrible comment system.

    GREENPOWERSCIENCE: The channel with the highest abuse of capital letters and over-tagging the title. Yet the channel is still just above 250k.
