   Sow a seed in a pot. When you need energy pull out the sow, dry it, and burn it. That’s renewable resource Enviro-whinerism! Also works with algae. Area (square miles) necessary to generate 1 GW electrical, theoretical minimum

   You can do a minmum pretty for $300. $300 buys 2500 kW-hrs of energy out of the socket.

   HI… REALLY A VERY GOOD QUESTION…..
   Using parts easily unfilled from your local stores, you can make a small solar power generator for $250 to $300. Fantastic for power failures and life outside the power grid. Power your computer, modem, vcr, tv, cameras, lights, or DC appliances anywhere you go. Use in cabins, boats, tents, archaeological digs, or while travelling throughout the third world. Have one in the office store room in case of power failures in your highrise. I keep mine in my bedroom where it powers my cd player, turntable, lights, modem, laptop, and (ahem) a back massager. I run a line out the window to an 8″ x 24″ panel on the roof.
   1. Buy yourself a small solar panel. For about $100 you should be able to get one rated at 12 volts or surpass (look for 16 volts) at an RV or marine supplies store.
   2. Buy yourself a battery. Get any size deep cycle 12 volt lead/acid or gel battery. You need the deep cycle battery for unremitting use. The kind in your car is a cranking battery–just for starting an engine. Look for bargains, it should cost about $50-60.
   3. Get a battery box to place it in for $10. (This is excellent for covering up the exposed terminals in case there are family about If you going to install the system in a pump shed, cabin, or boat, skip this.)
   3. Buy a 12 volt DC meter. Radio Shack has them for about $25.
   4. Buy a DC input. I like the triple inlet model which you can find at a car parts store in the cigarette lighter parts part for about $10. This is enough to power DC appliances, and there are many commercially unfilled, like fans, one-pint water boilers, lights, hair dryers, baby bottle warmers, and vacuum cleaners. Many cassette players, answering machines, and other electrical appliances are DC already and with the right cable will run straight off the box.
   5. But if you want to run AC appliances, you will have to invest in an inverter. This will convert the stored DC power in the battery into AC power for most of your household appliances. I bought a 115 volt 140 watt inverter made by Power-to-Go at Pep Boys for $50. More powerful inverters are unfilled by mail. Count up the number of watts you’ll be using (e.g., a small color box(=60 watts) with a VCR(=22 watts), you’ll need 82 watts).
   6. Use a drill to attach the meter and DC input to the top of the box.
   7. Use insulated wire to attach the meter to the wingnut terminals on the battery. Connect the negative (-) pole first. Only handle one wire at a time. Connect the DC inlet to the battery in the same way. Connect the solar panel to the battery in the same way
   8. Close the lid (I use a bungee cord to keep it tight). Place the solar panel in the sun. It takes 5-8 hours to charge a dead battery; 1-3 hours to top off a weak one. It will run radios, fans, and small wattage lights all night, or give you about 5 hours of unremitting use at 115 volt AC, or about an hour boiling water. This system may be added on to with larger panels, inverters, and batteries.
   Options: A pop-up circuit breaker may be added between the positive treminal and the volt meter. Some of you will want an ampmeter as well. The panels I recommend have built-in bypass diodes, but I recommend charge controllers for people who have panels without diodes. Another option is a voltage valve, which is not necessary for a system this small, but a larger system would require one.http://www.rain.org/~philfear/how2solar.…

   Very simple
   Depending on your budget, buy a solar panel
   If you want more power, add more panels
   If you want to store electricity buy rechargeable batteries
