A Hawaiian company’s plan to raise millions of pounds of sashimi-grade tuna in giant “environmentally friendly Oceanspheres” two miles off Hawaii’s Big Island has been approved by state regulators, the company confirmed today. The state Board of Land and Natural Resources voted last week 4-to-1 to give  Hawaii Oceanic Technology  permission to install three large underwater cages for the tuna, the Associated Press reported. “But the board is requiring the company to return for permission to

Space Weather News for Oct. 28, 2009 http://spaceweather.com INDONESIAN ASTEROID: Earlier this month, with no warning, a 10-meter wide asteroid hit Earth’s atmosphere above Indonesia and exploded. The break-up was so powerful, it triggered nuclear test ban sensors thousands of kilometers away. A just-released analysis of infrasound data shows that the asteroid detonated with an energy equivalent of about 50 kton of TNT, similar to a small atomic bomb. This significant impact has received r

Countries that provide robust incentives for the renewable energy industry create a more attractive environment for investors, a new study suggests. Countries that adopt policies obliging utilities to purchase a percentage of their power from renewable sources at above-market prices — also known as a “feed-in tariff” — represent the safest harbors for investors looking to finance clean-energy ventures, according to a broad-ranging risk analysis released Monday by Deutsche Bank’s global asset man

With many contraptions and inventions popping up in all four corners of the earth, the best thus far is the home wind energy . How Do These Home Energy Turbines Work? A home wind energy turbine is installed on top of a tall tower or prop at your home which collects kinetic energy (which is energy possessed by an object resulting from motion of that object) from the wind and converts it to electricity that is compatible with a home’s electrical system. For normal home use, the home wind

Global warming will leave the Arctic Ocean ice-free during the summer within 20 years, raising sea levels and harming wildlife such as seals and polar bears, a leading British polar scientist Professor Peter Wadhams of the University of Cambridge said on Thursday.  Much of the melting will take place within a decade, although the winter ice will stay for hundreds of years. The changes will mean the top of the Earth will appear blue rather than white when photographed from space and ships will

Solar cooling is provided by the same solar energy that gives us warmth in the cooler months of the year. There are a few ways solar cooling can be achieved. Solar cooling can be made by using a passive solar cooling system. The passive solar cooling system has a storage medium that gathers heat from the sun during the daylight hours. During the daytime the solar collector stays shaded and at night the solar collector is taken off of the solar cooling system. Once the solar collector is taken

Are you looking for a way to reduce your impact on the environment? Look for a way to relieve strain on the Earth’s energy sources with Energy 4 Earth. What is Energy 4 Earth and how can it solve the problem of costly renewable energy sources? First, what is Energy 4 Earth? It is an ebook download that contains invaluable information to guide, inform and how to use wind or solar energy made at home. This brings us to how it can solve the cost part of wind and solar power. Planning and b

The United States produces 6 billion metric tons of CO2 annually. Yes that is Billion! Forty percent of carbondioxide (CO2) generated in the US comes from the generation of electricity. We are certainly not the only offender, but we are one of, if not the largest, contributor to the greenhouse gas problem. The accumulation of greenhouse gasses is causing the earth to warm, reducing the size of ice deposits in the Arctic, Antartica, and Greenland. this has aready caused severe problems for sm

by Evans D. Smith There are numerous reasons that you should be making an attempt to do well for the environment. There’s a lot of pollution nowadays, and the earth has suffered due to stuff like greenhouse gasses and global warming. There are plenty of things you can do , for example recycling and not driving when possible, but there are larger things that you can do to take part. Using solar energy energy is one of these things. How It Works It is simple to find out how solar electricity

With technology similar to that used by physicians to perform magnetic resonance imaging (MRI) scans, researchers from six institutions — including the National Institute of Standards and Technology (NIST) — working at the Hollings Marine Laboratory (HML) in Charleston, S.C., are studying the metabolic activity of a pathogen shown to cause coral bleaching, a serious threat to undersea reef ecosystems worldwide. Coral bleaching is the whitening of living coral due to a disruption of the symbiosis
