  Trees Shading Solar Panels Ordered Cut Down 2008-03-01 04:07 Makarand

Submitted by Makarand on Saturday March 01, @04:07AM
Makarand writes "A landmark case pitting trees against solar panels was fought in the courts of sunny California recently. A judge ordered some towering redwoods cut down so that sunlight could shine on solar panels installed by a neighbor even though the redwoods were planted before the solar panels were installed. A three decade old Solar Shade Control Act passed in California when solar systems were rare now requires homeowners to keep their trees from shading more than 10 percent of their neighbor's solar panels between 10 a.m. and 2 p.m. The solar system owner is happy with the outcome of this judgment because he thinks that it would take around three acres of similar trees to reduce carbon dioxide emissions as much as the solar panels he has installed."

Makarand writes "India and China have educational systems that are more rigorous and one-track than anything we have in the United States. A new documentary highlights this by following two students from India, China and the United States while they spend time in high school. The documentary, aptly called "2 Million Minutes", assumes that students roughly have 2 million minutes in high school to prepare a solid foundation for their college studies and careers. The documentary makes the observation that students in India and China are years ahead of their peers in the United States in terms of preparing to play in the global economy."

  Heating Your Home With A Geothermal Pump 2007-05-01 15:55 Makarand

Submitted by Makarand on Tuesday May 01 2007, @03:55PM
Makarand writes "This article in the Chronicle describes how geothermal pumps could be used to heat our homes instead of natural gas or electricity. These pumps rely on the fact that regardless of what the surface temperature of the earth is, it is always 60 degrees a few hundred feet below. You have to drill a few holes 200 feet deep and insert U-shaped tubes in them and connect these to a heat exchanger. The tubes are filled with a solution of water and alcohol to prevent corrosion. Circulation pumps drive the water solution through the tubes in the ground and when the solution comes up from underground it is warm because it has passed through an environment of about 60 degrees.The heated liquid then is passed through the heat exchanger which takes care of the business of heating your home."
