Resources for Alternative Energy
By Dave Kettner

There are many different forms in which alternative is available.

One of these is solar power. Solar power is driven by photovoltaic cells, and these are progressively getting less expensive and more advanced. Solar power can be used for electricity, heating, and making hot water. Solar produces no pollution, as its input comes completely from the sun's rays. However, much more work still needs to be done in order for us to economically harness the sun's energy. For the time being, the resource is a little too conditional—storage batteries are needed to be used as backups in the evenings and on inclement days.

Wind has become the most-invested-in (by private investors and governments together) alternative source for the time being. The great arrays of triple-bladed windmills are being placed all over as “wind farms”, to capture the motion of the wind and use its kinetic for conversion to mechanical or electrical energy. Of course, there is nothing new about the concept of a windmill for harnessing energy. Modern wind turbines are simply are more advanced variations on the old theme. Of course, the drawback to wind is...what do you do when there is a calm, still day? Needless to say, during these times the electric company kicks in for powering your home or office. Wind is not altogether independent.

Hydroelectric is available as a source of alternative energy, and it can generate a substantial amount of power. Simply put, hydroelectric uses the motion of water—its flow in response to

Commercial Digital Hydroxy Controller Revolutionizes the 'Meyers Symmetrical Pulse Mode' Concept
Square1 in Kentucky, USA, will soon be releasing their Hydro-Maxx controller that will help HHO researchers get the most from their hydroxy units, possibly even unleashing Meyer's Mode -- the holy grail of water fuel. (PESN; Aug. 29, 2010)
Report on 2010 Colloquium on Lattice-Assisted Nuclear Reactions at MIT
Now in its 19th year, this annual cold fusion colloquium focused on work and effects that are related to new materials and devices, including nanomaterials. The math apparently says that the energy in 3/4 of a gallon of heavy water could power Boston for a day. (PESN; Aug. 28, 2010)
The Marko Rodin Coil

gravity, which means downhill—to turn turbines which then generate electrical energy. Needless to say, water is ubiquitous; finding sources for driving hydroelectric turbines is, therefore, not much of a problem. However, hydroelectricity as a source of alternative can be complicated and expensive to produce. Dams are often built in order to be able to control the flow of the water sufficiently to generate the needed power. Building a dam to store and control water's potential and kinetic takes quite a lot of work, and operating one is complex as well,and conservationists grow concerned that it. Of course, a dam is not always needed if one is not trying to supply the electrical needs of a city or other very densely populated area. There are small run-of-river hydroelectric converters which are good for supplying neighborhoods or an individual office or home.

Probably the most underrated and under-appreciated form of alternative is geothermal energy, which is simply the naturally-occurring produced by the heating of artesian waters that are just below the earth's crust. This heat is transferred into the water from the earth's inner molten core. The water is drawn up by various different methods—there are “dry steam” power plants, “flash” power plants, and “binary” power plants for harnessing geothermal energy. The purpose of drawing up the hot water is for the gathering of the steam. The Geysers, approximately 100 miles north of San Francisco, is probably the best-known of all geothermal power fields; it's an example of a dry stream plant.
