There are most definaely small hydro power generators for the home. There are a great device for saving energy and making electric power. They are becoming more mainstream.
Hydro generators are used to power cities, towns and many homes and businesses. They generate electricity that is used both residentially and commercially.

Hydro plants range in size from arbitrarily small to the largest power plant in the world. On the small side, there are hydro power generators that literally can fit onto a person's hand, with very small output. Some people use very small generators to produce power for their homes or for other off-grid use of power. There is no reason why a much smaller model could be produced, though it would probably not have a practical application. The Three Gorges Dam in China is the largest electric plant in the world, in terms of output. It currently has an output of 18,200, but will not achieve full power until 2011, when its output will be 22,500 MW. This is several times the output of a large nuclear facility.
it comes from turbines and generators.
typical power plant generators produce from 50KVAC to 150KVAC regardless if they are hydro, coal, natural gas, etc.
electrisity comes from big electricity generators .
By using water pressure to power generators.
You can get informatino on small generators by visiting a heating and cooling store which sells generators and furnaces and speak with a representative.
Hydro-power is electricity created when water is forced by gravity from a dam and through turbines. The spinning turbines turn generators, and electricity is produced.
Hydro generators generate electricity from flowing water. THey can range from several hundred dollars to several thousand, depending on the brand and how much it can process.
Thomas Edison invented the incandescent light bulb and with JP Morgan they brought electricity to customers with small generators.
there are currenty no generators for home that are realistic available. There are some being tested in scotland and japan
