Solar Can See Clearly Now: New Solar Concentrators Could Dramatically Reduce the Cost of PV

A new technology developed at MIT, solar concentrators, could dramatically reduce the cost of photovoltaic (PV) power.

Video Contest for Alternative Fuels

T. Boone Pickens is calling Americans to submit videos about the importance of independence from foreign oil. The contest ends Oct. 25, and the winning video will be sent to national political leaders.

Solar Panels Get a Make-Over

A new company has redesigned the typical shape of solar panels to be more three-dimensional.

The Last Presidential Debate and Energy Talk

The Presidential candidates had one last chance to address energy policy.

How Renewable Energy Can Help Combat Poverty

Here's another reason to love solar panels and wind turbines: They're great tools for providing power to people who wouldn't otherwise have electricity at home.

Best States for Energy Efficiency

California ranks No. 1 on the ACEEE's scorecard of energy efficient states. See how your state ranked here!

World Geothermal Power Generation Nearing Eruption

With the search for an alternative type of energy in high demand, geothermal energy ? energy from the Earth's core ? could be a viable solution. Thirty-nine countries have the geothermal energy resources they need to give power to all 750 million of their residents; and after the passage of the Earth Policy Act of 2005, seven thousand jobs are expected to be created by this industry in the United States alone.

What's Your Solar Potential?

This handy online tool helps calculate your solar energy potential based on your location.

Freezer Pleaser: Launching an Eco-Friendly Way to Keep Ice Cream Cold

Ben& Jerry's teams up with Greenpeace to bring the U.S. a cleaner way of freezing food, especially ice cream.

A New Way of Looking At the Bailout

Everyone's talking about the economic bailout, but few seem to focus on the bigger issue: we need more jobs, and we need a viable economic stimulus. One study shows those needs could come from green investment.

It's Time to Act on Climate Change

The news on climate change isn't good, but renewable energy could lead us to a brighter future.

Interview with Raser About Their Cost-Effective Geothermal Power

Company has a rapid-deployment capability for low-heat geothermal energy. The geothermal pipes are in a closed loop, tied to a heat exchanger that heats a refrigerant which runs a turbine, in a reverse-refrigeration system, generating electricity in a cost-effective manner. (PESN; Sept. 4, 2008)

Levon Light

Leif Levon's environmentally friendly inductive light. No batteries. It operates on ambient superfluous light during the day and induction technology when the light is too dim. (PESWiki; Sept 13, 2008)

George Soukup's V-Track Rotary Magnet Motor

German inventor presents what appears to embody the V-track magnet accelleration model into rotating motion -- something that many have unsuccessfully attempted. What is not clear is whether his model achieves acceleration, or even constant speed. Can it handle a load? (PESWiki; Sept 15, 2008)

Lee-Tseung Lead Out Theory

Theory predicts that both gravitational and electron motion energy can be lead out via pulse force at resonance on oscillating, vibrating, rotating or flux change systems. The ideal pulse force for a simple pendulum can be thought of as the pull applied perpendicular to the arc of motion when the pendulum bob is at the maximum displaced position.

Groundbreaking Energy Ball Wind Turbine for Home Power

The Energy Ball designed and built by Home Energy in the Netherlands, breaks from most wind turbine design by using a spherical structure. They say that by using such a design, significantly higher aerodynamic efficiency can be achieved (40 percent better efficiency), as compared to traditional designs. (PESWiki; Sept. 17, 2008)

XR-3 build-it-yourself hybrid car by Robert Q. Riley Enterprises, LLC

The XR3 Hybrid is a super-fuel-efficient, two-passenger, plug-in hybrid that achieves 125 mpg on diesel power alone, 225 mpg on combined diesel and electric power, with performance like a conventional automobile, focusing on existing technologies that make conserving energy a fun driving experience. (PESWiki; Sept. 20, 2008)

Micro-Inverters make solar modular

Enphase Micro-Inverters turn solar panels into modular systems, increasing the energy harvest by 13 to 15 percent. The system includes the micro-inverter, embedded powerline communications and Enlighten -- a web-based performance monitoring and analysis tool. (PESWiki; Sept. 22, 2008)

Keppean Scalar Motor Demonstration Under Way

The Keppe Motor allegedly requires a quarter as much electricity to generate power as a normal motor -- by capturing scalar energy from the 'vacuum' of space. It is named for Brazilian scientist, Norberto Keppe, Ph.D., whose book The New Physics Derived from A Disinverted Metaphysics proposes a spiritual-based direction for our planet's technological philosophy. (PESWIki; Sept. 23, 2008)

Why Wind Power Works for Schools

More than 100 schools in 30 states have installed wind generators, and many more are doing the research to see if wind will work for them. The systems not only provide greater energy security and lower bills, but they also teach the students and the community about the benefits of renewable energy.
