Why can't we use solar energy or a large rechargable battery to power certain household items?
I've been thinking about the huge cost of electricty just for our appliances. Is it possible (and cost effective) to use some solar (or other alternative power) to run just some items like our clothes drawer, water heater, oven, dishwasher, refridgerator, and AC unit?
I don't need something that will power my whole house . . . rather just run some of these items so I can get off the grid.
Let me know your thoughts.
Most appliances are available on the market which run off DC electricity, everything from TV's, washing machines and refrigerators. They are generally used by campers/caravaners, but can also be used in the house. In my last house, I lived totally off the grid, supplying all of my own power by a combination of 2 small wind turbines and 10 solar PV panels. Check out caravan supply stores as all the products they have can run off batteries (12 volt). Also anything that you can charge in your car, such as a mobile phone or laptop, can also be powered from 12V electric. Alternatively, you could disconnect your lighting from the grid and wire it up to a solar or wind set up, though you would need to change the bulbs to a 12V type. Special energy saver bulbs and my favorite, LED's can both run off a battery. It also helps if you are prepared to sacrifice a little bit, such as a laptop uses less power than a PC and there is no need to own a TV if you have a laptop, as you can watch TV programs on your laptop. It also saves the need for a DVD and CD player, so more money is saved not just by not buying new goods, but in having multiple uses for the goods that you have. Besides, using a laptop to it's full potential, also saves repair costs as it's easier to guarantee and repair one item than it is to do the same for a multitude of them. The sacrifice is that your screen is probably smaller than what you may be used to - not much to save money and the environment is it? Going green is in part about smart thinking...
solar energy activity for kids?
I need a project to do with this kit that I got. It comes with a little solar panel, and a battery thingy. What can I do to make something work with the energy I harness? Or what else can I buy ( that's not a million bucks!!!) to make something work?
try to buy a small motor and make a boat using recycled materials. we have an activity in our class about boat with solar power. we even made it a race to be more exciting. that is just my opinion, you can find more.
