Alternate ways to harness energy from sunlight?
I’m about to build a home energy source and was considering solar cells and fans (air), anyway. Solar cells are expensive and do not really generate much power. The area is about 30 cm2. I have seen that it is possible to construct cells lots, they generate very little electricity. So what I can use instead of solar cells (from sunlight or UV rays)? Is there any way to create cells most powerful solar at home instead of buying? How? Ps this is for a school project, so I need cheap and effective solutions. Thanks!
Probably you can easily build a solar heater yourself. A solar heater is simply a panel with water channels, or tubes that pass through solar concentrators (Parabolic mirrors or lenses) that capture and concentrate solar energy to heat water. Remember kill ants with a magnifying glass? This is the same concept. Solar heaters can generate electricity very efficiently if the water can become steam. You could use a steam turbine, if they have a (probably not). Or, you could build a small fan connected to a DC motor and a little cheap to run the fan for the steam and water vapor that comes at the end of the tube. This should easily generate enough electricity to power a small LED bulb or a few. To do this experiment needed at least a dozen plastic magnifying glasses and probably about 6 feet 1 / 8 “diameter copper tubing. copper tubing usually costs a few dollars per foot, and you can take advantage of inexpensive lenses for increase in most dollar or thrift stores. simplest way I can think about building this thing would be to take two flat plates and create an L-shaped platform long. Straighten the copper tubing and necessities to one of the boards. Here is a cross sectional view of what I mean Copper tube Then screw the stems of the glasses increase for the right side of the bottom board, ensuring that the distance between the copper tube and the objective party of lens focal length of the maximum heat output. Increase Then attach Lens water tank at the side of tube, point the device in the sun and see how hot it gets. Anyway, sounds like a fun project. Have fun and good luck.
