Well I have just passed legislation that will enable students to receive funds directly from these companies that hopefully will increase interest in projects around the country.

Hope this helps,

You can survey your house and determine the volt-amps (watts) of all the stuff then convert that to kilowatts. Then estimate the time cycles of the frig, the tv computer lights convert that to hours and add it all up. Ex: A 120VAC fridge has a name plate that indicated it pulls 3.7 A. That means 120*3.7 = 444W = .444 kw. If it cycles on and off on average every 15 min (.25 hr) it used .444 kW * .25 hr =111kw-hr. Do that for the TV compoyer lights everything. That will put you in the ball park.

Or You can buy these nice devices that you plug into and that plugs into the wall and measures the amps and totals the kilowatt-hours for any device. Just plug it in and come back later and see what it reads. Go through that for everything and add it all up.

But realistically, the best way is to go to your electrical meter every night at the same time and record the kilowatt hours. The meter totals so subtract today’s reading from yesterdays to get what you consumed the past day. Do this for some time and get an average. Your electrical bill will also have all this information as they read the meter too. So read it and check out how it varies with the season.

What agent?

These kind of deals are done directly between the manufacturer and the purchaser. ANy “agent” is probably an employee of the manufacturer, and makes a salary with the probability of a year-end bonus based on company profits.

The shut off speed depends on the design of the turbine. They vary.

If you can get the model number, the manufacturer may give you more information.

Sun heats the surface of the earth unevenly.

Uneven heating give rise to large scale winds.

Wind turbines are strategically placed to capture as much wind power as they can.

The wind blows on propellers that are attached to the shafts of electric generators.

So the heat of the sun is converted into wind energy, then that wind energy is converted into the rotational motion of the shaft which is ultimately converted into electricity (and heat).

You can use a bicycle wheel, with blades mounted, to drive a bicycle generator. Fashion blades by cutting large diameter PVC tubing lengthwise (splitting it) on a taper so the blade is thinner at the tip. You can make two blades from one piece of tubing if you cut it properly. You can mount them to the spokes, between the hub and rim.

I haven’t seen these bicycle generators around for a while, but I assume they’re still available, with a small knurled wheel that drives from the rim of the wheel. The generators have very good output at low rpm, so they are ideal.
