Interested in electrical engineering? Here are five universities that offer free electrical engineering courses online.

Data Center University™ (DCU) offers industry-leading education for IT professional‚ facilities managers‚ engineers‚ designers‚ consultants‚ and anyone involved in the critical decisions and infrastructure planning of data centers worldwide. The changing nature of data centers‚ and the technology that impacts the‚ makes it even more critical that employees remain up to date on the current theories and best practices for issues around topics of: power‚ cooling‚ management‚ security‚ and planning.

You’ve always been able to burn energy at the gym. Now, you can create it too.The Green Microgym, in the Alberta arts district of northeast Portland, opens this week and aims to turn human energy into electricity.Adam Boesel, a personal trainer and the owner of the gym, rigged up spin bikes with weedwacker motors and truck alternators in hopes of creating the first human-powered gym in the United States.

A company called M2E Power has announced plans today to release a charger that will powered by kinetic motion. The released date is expected to be next summer. The charger derives power from the motion of walking, jogging, cycling, or driving. Six hours of motion provides 30 to 60 minutes of charging power. It will be priced between $25 and $40.

And that's not all. We reported recently on this site on the solar powered car making its way around the world. We also covered the concept of solar roads to capture usable energy. We even reported on a sail boat powered with a solar sail. Now the BBC reports   that the U.S. military has held a test run in Arizona of a UK-made solar plane, the Zephyr-6. The plane flew for more than three days, running at night on solar charged batteries. The more than 83 hour non-stop flight was the longest of any unmanned aircraft.

The most efficient form of renewable energy may be right underneath us. Researchers at Worchester Polytechnic Institute (WPI) in Massachusetts announced today that they have discovered a method to use road surfaces for solar collection.

Given its limited reserves of natural uranium and its abundant supply of thorium, India has chalked out a unique three-stage nuclear program. In the first stage, pressurized heavy water reactors (PHWRs)—similar to those used in advanced industrial countries—burn natural uranium. In the second stage, fast-breeder reactors, which other countries have tried to commercialize without success, will burn plutonium derived from standard power reactors to stretch fuel efficiency. In the key third stage, on which India's long-term nuclear energy supply depends, power reactors will run on thorium and uranium-233 (an isotope that does not occur naturally).

Small-scale wind energy (wind turbines <50kW rated capacity) is receiving increasing interest as one of a number of microgeneration technologies with potential to reduce carbon emissions. Recent years have seen new products being made available on the UK market, which a survey by the British Wind Energy Association (BWEA) suggests is growing quickly.

FACT: There aren't enough resources on this planet to sustain continued human growth and increasing quality of life.FACT: If we want to avoid catastrophic war, suffering, and global shortages of energy, we need to start looking to space seriously for solutions.Space Based Solar Power is the first step.

PASADENA, CALIFORNIA:  The world's most promising regions for offshore wind power have been revealed in satellite images from NASA.  The northern U.S, Canada, UK, Japan and Eastern Russia have the most potential in the Northern Winter, while southern Australia, South Africa, New Zealand and Argentina benefit from the most consistent and powerful winds in the Northern Summer.

REpower Systems AG has successfully installed the first of six wind energy turbines for the Belgian offshore wind farm Thornton Bank. The project, located about 30 kilometers off the coast, is the first Belgian offshore wind farm. For the first of three construction phases, REpower is providing six 5-megawatt (MW) offshore turbines, adding up to a total capacity of 30 MW.
