Light shining on a properly created solar cell. A solar cell can consist of an impure (doped) silicon (usually with phosphorus) with metal wire laid on top of it and then covered in glass (for protection, perhaps it might help build up the heat, but I'm not sure). When the light's energy hits the silicon, it knocks free electrons (from the phosphorus mostly) and then the wires will pick it up. Howstuffworks is a great site for this sort of question.

If the element is bad it will take forever to heat hot water back up. I would check that first before you put alot of money into it. Hope this helps.

radiation? do you hear yourself?\n\nit looses heat b/c it doesn't get enough energy to keep it warm!  a solar cover is a good way to create that needed energy as it uses the suns rays and not weighing down your electricity bill.

The cheapest PRACTICAL way of using solar energy at home is to make a solar cooker. \n\nThis is not a solar 'oven' with a big lens or mirror that broils things, it is a box painted black that gets hot as it sits out in the sun the same way your car does. They only cost a few bucks to make and they WORK! I made one and it works!\n\nYou will need two cardboard boxes that fit inside each other, some black paint, aluminum foil, glue or tape and a plastic oven- roasting bag like for a Thanksgiving turkey.\n\nIt is a slow cooker. You can't burn anything in it, because it only gets up to about 320 degrees F. in it. The beauty of it is that it saves you energy (and money) two ways: first, you don't need to run your stove on a sunny day to cook. Second, you don't need to run your air conditioning extra because you didn't heat up the house with the stove on!\n\nSearch on solar cookers. You will find sites with plans and step by step directions. Have fun!\n\nPS. Beckee, I have to admit, your idea is the cheapest and the easiest. I forgot!

try painting the cup black and setting it in the sun, perhaps setting it on a mirror

You aren't going to get much sun light at night for your solar panel. There are MANY CHEAP nicad battery powered yard lights on the market that use a small solar panel to charge the battery in the day time. They have IR sensors that turn the light on at dusk and off when the sun comes back up. I doubt if you can build one cheaper than you can buy one, if only as a hobby, Edmond's Scientific and Radio Shack sell kits for that use.

Does the "promotional litearture" keep you warm?  Try burning it, that might produce some heat.\n\n$300 is too much, you need that money to pay your heating bill.  Anyway, I seriously doubt quartz is any more efficient than a cheap space-heater.  They're both 100% efficient at converting electricity into heat.  To improve on that you need a "heat pump".  \n\nThose are just an air-conditioners that are turned around, so that instead of pumping heat out in the summer, they pump heat inward in the winter.  To use one you need a source of heat that is above 40-50 deg.F, such as well water.\n\nYou can als:\ndress more warmly\nturn up the thermostat\nget another space heater\nadd insulation to your house

If you want some info look at this magazine call mother earth news it has alot of info on solar energy, solar heating and other stuff. Try it, i'll give the webs site of were to get it. I am always look at solar earth and cheap heating. i hope this helps http://www.motherearthnews.com/

If u want something easy u can make a rpleca of the solar system. U can by those foam balls and spray paint them. Or u could do an experiment on two plants giving one sunlight and no light to the other. But still feed and water them.

Solar electric panels are made up of something called silicon, the same thing that makes up sand. There is more silicon on the planet than almost anything else. Even though you can find silicon almost everywhere, making a solar panel is difficult and expensive. The silicon has to be heated to super high temperatures in a big factory, and then formed into very thin wafers. \n\nWhen sunlight hits a solar panel, it makes electrons in the silicon move around. (Electrons are teeny tiny specks--they?re way too small for us to see, even under a microscope.) The electrons flow through wires that were built into the solar panel. And presto! We have electricity! We can do whatever we want with this electricity, run a calculator, a CD player, or, if we have big enough solar panels, a satellite! [Solar panels are also called photovoltaic panels. "Photo" means light and "voltaic" means electricity.]

blink a ton. just start blinking repeatidly while cutting the onion. the faster you blink the better,  \n\n\nto make solar oven you should get a carboard box and paint it all black. then cover it with aluminum foil. exact details should be online. just type in solar cooker in google to get exact details.

This website may help, not only does it have a picture, but it has step by step:)\nhttp://www.enchantedlearning.com/crafts/astronomy/solarsystemmodel/\nI would use the foam balls instead of the tag paper. If you need to make it to scale this website might also help:\nhttp://www.exploratorium.edu/ronh/solar_system/index.html

Do a search on this site..  \nregarding solar energy.

Cut a hole and mount a small enclosure cooler (alcohol vapor)\n\nIf cutting a hole is not an option then fabricate a heat sink and have the cooler blow on the heat sink.\n\nuse a simple house type thermostat for temperature control.

Unfortunately you've got an old fashion landlord who does not appreciate you as he should. Keep the pressure on the landlord to replace the heating equipment and buy yourself one or two room heaters. You could report this habitability violation to your local buidling code inspection department. And let them "persuade" your landlord into providing proper heat to your home.
