Think it thru

Yes. As a good example almost any ceiling fan is reversible by moving the position of the forward/reverse switch.

I don't know if you need a certain shape of magnet for your applications but there are strong magnets in computer hard drives which can be gained for free much of the time. They'll certainly bite you if you get skin between two of them.

Thanks. I appreciate the explanation so that I may learn.

While far from perfected but of interest is the work of Dr. David Faiman in Israel. I want to clearly state that he is not using silicon photovoltaic cells, but another kind. Dr. Faiman is focusing his work (pun intended) on using mirrors to focus light onto a 4 inch solar cell which is putting out 1500 watts instead of the standard 1 watt per normal sized cell. Quite impressive numbers in the video. http://www.israel-times.com/business/2007/08/israel-new-solar-energy-breakthrough-magnifies-the-sun-x1000-2865/ Further, on the average number of KWH used per person in the US---as far as HOME energy consumption goes I generally use less than 250 KWH PER MONTH with consumption sometimes falling below 180 KWH per month. That means my monthly home use is less than the average use per day. Typical electric bill is less than $25. I hope to eventually switch to off grid solar, perhaps supplemented with wind electrical generation. I'm with T. Boone Pickens, there is a lot of untapped and under utilized wind energy for the taking.

I'll buy that because, like I said, I simply don't know. I do know that in some of the oil fields they run wires beside the pipelines to the tank batteries and they are ultimately hooked up to electricity, i.e. meter and equipment. ??

Will this site help? http://www.robotoys.com/st_sresults.html Lots of robot toys, for the ones on the page I linked to I searched for programable robots. You might search Ebay and other sites too.

Could a form of electrolysis cause an ionization of the water to prevent scale? I'm asking, I don't know. Oil field piping, city water mains, etc. use electrolysis to prevent rust/corrosion but does it prevent scale?

Most of the ideas seem like overkill to me. Wouldn't it be simpler to get an automobile coil and a coil wire from a parts house and collapse the field in it with a momentary switch, telegraph key, or old auto distributor? Maybe parts houses aren't as readily available to you as they are to me. A late 1940s to mid 1950s 6 cylinder Chevrolet engine coil would be ideal. Ask for a 12 volt replacement one instead of the 6 volt one however. If you use a distributor you could even rig sparkplug wires to sparkplugs set in a show board of plexiglas and then use a crank or a crank/pulley system to turn the distributor which opens and closes the point set causing the electrical field in the coil to collapse causing the higher voltage spark. Guess I should rig up such a deal for my grandsons or the local kids museum.

You may wish to read about this electric tractor, a gas tractor conversion. http://www.flyingbeet.com/electricg/ Along the lawn tractor size-- http://www.elec-trak.org/ Off topic about an electric tractor, but one can eliminate the energy need to produce the no-till chemicals by growing organically as per respected Rodale Institute and their New Farm Web site. http://rodaleinstitute.org/new_farm Instead of spraying to prevent weeds a cover crop is flattened to form a mulch mat which is then planted into. The green manure crop that is used as the mulch is killed with a chevron shaped easy pulling roller rather than with chemicals. http://www.newfarm.org/depts/notill/features/2006/0506/drawings.shtml For large scale agriculture here in the United States no-till tractors would be between 100 and 200 horsepower and be pulling 16 row no-till planters. Those planters use a lot of down force to cut through old reside so are heavy which makes them pull hard, hence the horsepower need. I don't know a single farmer that wouldn't welcome a tractor capable of replacing an 8 gallon, $40 per hour fuel burning tractor with one of practicality and reliability. The problem with an electric tractor comes with the hours operated. Many are the days I have operated a tractor 12-14 hours and some operators farm longer hours. How will you store 12-14 hours of 100 horsepower energy?

It reminds me of the Carrot2 search engine which clusters---like bunches of carrots? http://demo.carrot2.org/demo-stable/main

What kind of glass are you speaking of, safety glass, common window pane glass, or ???? I have never seen common window pane glass turn opaque when shattered, the shards always stay transparent.

This site should let you gather knowledge of aerogels. http://p25ext.lanl.gov/~hubert/aerogel/ This one as well via NASA. http://stardust.jpl.nasa.gov/tech/aerogel.html and from that site-- It is 99.8% Air Provides 39 times more insulating than the best fiberglass insulation Is 1,000 times less dense than glass Was used on the Mars Pathfinder rover --------- I can't wait to build a new home using it for windows.

The first thing that would happen upon entering a hole into the interior of the earth is that we would quickly learn what has never been known before. One must assume that you are not familiar with the theories of John Cleves Symmes, Jr. who in 1818suggested that the Earth consisted of a hollow shell about 800 miles thick with openings at each pole, nor subscribe to his beliefs. http://en.wikipedia.org/wiki/Hollow_Earth For your entertainment: http://www.ourhollowearth.com/SmokyGod.htm'>http://www.ourhollowearth.com/SmokyGod.htm http://books.google.com/books?id=ZG0mAAAAMAAJ&pg=PA170&vq=%22A+strange+manuscript+found+in+a+copper+cylinder%22 May I also suggest the Jules Verne classic "Journey to the Center of the Earth". http://www.online-literature.com/verne/journey_center_earth/ There have been a number of movies on the topic as center earth exploration. For further reading: http://www.ourhollowearth.com/ Perhaps you would like to take an exploration trip yourself in 2009. http://www.phoenixsciencefoundation.org/APEX_apply.htm As to what I personally believe---does it matter? What you believe is all that really matters.

Oh boy, another new guy. Dare to dream. Dare to be different. Dare to toss out off the wall ideas for others to build upon. For these very reasons we have automobiles, airplanes, computers, and have had men on the moon. Brain power, use it.
