Joe Holden – Revolutionary Mini Hydro Power

Joe Holden, Inventor of the first afterburner for Jet Engines at Rolls Royce, applies his knowledge to Sustainable Energy. He shows us a Min Hydro Plant that uses his proprietary “Compression Tube” technology that can make a meter squared hydro plant…

Small hydropower to reach 140 GW in 2015

Well, GlobalData points out that small and mini hydropower generation plants have shorter gestation period (2-5 years) compared to large hydropower plants (7 years). Additionally, small and mini hydro gives a higher return on investment …

Even if you are very careful about turning off lights when not in use and otherwise not wasting energy, your electricity bill is probably still fairly high. If you’d like to slash that bill – and help save the planet at the same time – then you definitely need to consider solar energy. The prime benefits of solar energy are outlined for your convenience below.

Do Your Part, Go Solar.

Around 90% of the electricity that is used in Australia is produced from fossil fuels. Unfortunately, greenhouse emissions are the natural byproducts of this form of energy. These emissions pollute the atmosphere and compromise the health of the planet. Every time you flip on a switch in your home, you’re indirectly helping to pollute the planet.

Instead of being a part of the problem, you can use solar energy to be a part of the solution. Solar energy is very clean and exceptionally efficient; by using it, you can reduce your reliance on fossil fuels. As more and more people turn to solar energy, less and less greenhouse emissions will be produced. By taking advantage of the power provided by our sun, you can make a difference yourself toward saving our planet without the need to spend a huge amount of time or money for it. Truly, solar power is one of the simplest ways to “clean up your act.”

Save Money on Energy Bills.

Every month, you probably cringe when your gas bill arrives in the mail. Energy costs have soared in recent years, and gas is extremely expensive. You can reduce your bill by a significant degree – or, in some cases, eliminate it altogether – by making the switch to solar power. Since solar panels get their energy from the sun, you don’t owe a bill to anybody. The more power you can collect and conserve from solar energy, the less you are going to spend on “purchased” electricity. Within a few months, your investment in solar energy will have paid off.

In these tough economic times, it is essential to find ways to save money. Solar energy is one of the best ways of doing so. Based on how high your personal monthly invoice is, you could be saving more than a couple of hundred dollars each month on what you spend. You can use the money you save for anything you’d like. At the same time, you can feel great about the fact that you are doing more to reduce the amount of pollution to our planet than you have before. Who knows – you might even inspire friends, family members or co-workers to follow suit!

 


Considering how much greenhouse emission is produced by regular energy consumption, it’s easy to see why Solar Power Brisbane is experiencing an upsurge in popularity lately. After all, Solar Panels Brisbane from companies such as Eco-Kinetics allow you to reduce your reliance on fossil fuels.

Can an air leak let turbines capture more energy?

Filed under Turbine Blades, Wind Power Projects

The airfoil is of a NASA/GTRI 2D CFD validation model, not necessarily the cross section of a turbine blade. Slots could be at the leading or trailing edges, depending on a required effect. A few slot dimensions are shown. Source: NASA.

An idea originally developed to increase the lift of slow moving aircraft wings and simplify helicopter rotors may soon improve the efficiency of wind turbine rotors and possibly reduce their manufacture costs. The aerodynamic idea of “circulation control” releases compressed air from narrow slots on the trailing edges of wings or hollow blades to change their aerodynamic properties. In aircraft, circulation-control wings increase lift, letting Navy aircraft fly at the slow speeds necessary for landing on an aircraft carrier, as well as take-off and land in shorter distances. In helicopter blades, the technique might simplify the rotor and its controls, and produce more lift.

The idea could also let wind turbines produce significantly more power than current blades at the same wind speed, 30 to 40% more by some calculations. [click to continue…]

Europe’s Carbon Mafia, And Ours

Posted 05/06/2010 07:18 PM ET

Corruption: The carbon trading system being pushed here has spawned crime and fraud across the pond. Cap-and-trade is not about saving the planet. It’s about money and power, and absolute power corrupting absolutely.

All across Europe authorities have been conducting raids, rounding up individuals involved in a new version of Climate-gate. This time the data aren’t corrupted. Europe’s Emissions Trading System is. The system is so sick, it’s turned out to be a scam built upon a scam.

Twenty-five people have been arrested in raids by British and German authorities as part of a pan-European crackdown on carbon credit VAT tax fraud.

U.K. officials announced raids on 81 offices and homes, nabbing 13 people in England and eight in Scotland. The operation involved 450 investigators from Her Majesty’s Revenue and Customs office.

German authorities raided 230 locations, including the headquarters of Deutsche Bank in Frankfurt and [click to continue…]

Google has invested in two wind projects including this 120MW project, Ashtabula II, in Barnes County, ND

Search engine Google has made its first direct investment in utility-scale renewable energy, at two wind farms in North Dakota.

The company announced on Friday that it has invested $38.8 million in the 120MW Ashtabula II wind project in Barnes County and the 49.5MW Wilton Wind 2 wind farm in Burleigh County.

The two wind farms in North Dakota were developed by Florida-based wind energy company NextEra Energy Resources, which sold $190 million in membership interests in its projects last week.

Using existing transmission capacity to deliver their power, the Google-backed wind farms generate 169.5 megawatts of energy – enough to provide electricity for more than 55,000 homes. [click to continue…]
