Go to Home Page ............................... Water Falls Two large ducts carry some of the
water from this river to a generating plant near base of fall. When the
river is near flood stage most of the water goes over the fall and the energy is
dissipated. Some estimate that the United States is only exploiting a
fraction of its potential hydro-electric Elimination of the burning of Diesel and Propane for heating could result as part expanded Natural Gas Network. Mr. Pickens and some natural gas suppliers have suggested that utilities stop burning natural gas and substitute green solar and wind power for electricity production. The gas could then be compressed and used to fuel trucks and cars. Thank God someone with capital is developing a serious green energy policy. Natural gas vehicles will require an expanded nationwide gas distribution system. The US already has an extensive natural gas pipeline. One of my first memories from my childhood in New York City was that we got gas for our refrigerator and stove from a Texas pipeline. We used coal for hot water and heat. My point is that the technology to ship gas long distances existed over sixty years ago. So expanding the current pipeline grid to reach every corner of the country, so that their are no dead zones where natural gas powered vehicles will find themselves without gas, is possible. However, the expansion of gas pipelines will be a major national project. I feel that the this expansion should should include service to those who are presently using diesel or propane to heat their homes. This would free up diesel and propane for use by vehicles that already exist. Many gas stations already provide propane service.
Cheap Oil, Oct.19,2008 Bad news for clean alternative
energy, Oil drops to about $70 a barrel. If your trying to sell or develop alternative energy, cheap oil is bad news, because it undercuts
alternative products.
Cogeneration growing. Central heating systems date back to the days
of DC power generation in lower Manhattan during the Edison/Telsa Era. High
Pressure Steam Plants provided steam
Heat Storage Heat storage are an important element of solar
power systems. Power plants that use concentrated solar heat to generate
steam to drive turbine driven electric generators, require heat storage to
maintain steady power output. See
reference article, Click here . Heat stored in super heated water can provide
steam to meet sudden changes in load.

Waterfalls resources. Here the scenic value of the waterfall exceeds the value of the lost electricity. Physics of Waterfall: At top, water has high potential energy due to its height. At bottom, potential energy is zero, and kinetic energy and momentum of water is high due to velocity of the water. In theory turbines placed inline with water stream could absorb the water's momentum and drive a generator. Of course it be difficult to build and suspend these turbine in water falls. Consider old fashioned water wheels ( see Water Wheels, Click Here) Water wheels about ten foot in diameter could be placed at base of waterfall without destroying scenic quality of waterfall. AS a matter of fact a waterwheel of less than 5 meters diameter, would be totally obscured by the mist generated by falling water. Of course an old fashioned waterwheel would be smashed to pieces if it tried to capture the kinetic energy of this waterfall. Capturing the energy from a rivers vertical velocity might not be practical today (Who knows what type of turbine will be invented 20 years from now?). It might be better to turn waterfalls off late at night until late morning and divert all water through turbines when no one is looking. I haven't seen any waterfalls shut down for power generation. I have seen cases where all but a trickle of a waterfall was diverted for agriculture. (See shut off waterfall, Snake River, Idaho )
Capturing the kinetic energy of horizontals flows of rivers or tides is coming of age. See East River Strong Tides Power Submerged Turbines.
Looking at above picture of Cedar river on its
way to Seattle's Elliot Bay, one might consider it a candidate for
small turbines. However, in the summer time the turbines would be standing in
the air. See picture below of same river. Turbines could be re- Click Here! To go to next page. Note: I selected this river a candidate for turbines, because I had some pictures handy. Science-ebooks.com is a one man operation not AOL. See all my eBooks and Webs, Click Here!
