The Backpack Power Plant

Soldiers could one day carry 600-W power plants on their backs, or set up arrays of up to 20 kW in streams deeper than 4 feet, if a prototype being developed by California-based Bourne Energy comes to fruition.

CERAWeek 2010: "Energy: Building a New Future"

For the past 26 years, Cambridge Energy Research Associates (CERA) has hosted an annual CERAWeek conference in Houston that is renowned for high-profile attendees from around the world. During the week of March 8, security was tight as oil ministers from the Middle East and CEOs from the largest oil and gas companies and electric utilities rolled into Houston to exchange ideas and forecasts. More than 1,200 delegates from 55 countries attended to hear more than 100 distinguished speakers discuss a business that seems to have renewed optimism about the future.

From GHG to Useful Materials

Could the transformation of carbon dioxide (CO2) into carbonates and oxides solve the problem of greenhouse gas emissions (GHG) from fossil-fired power plants? Some companies are betting that such processes could make everyone happy and even create new profits. Buzz has been growing about this approach, though the concept has been around for many years.

Marines Get Power from Waves

Ocean Power Technologies Inc. (OPT) announced on Feb. 1 that it had successfully deployed one of its PowerBuoy wave energy devices about a mile offshore from a U.S. Marine Corps Base on the island of Oahu in Hawaii. The device generates up to 40 kW of power from the rise and fall of waves, and since its deployment in December 2009, it has been generating power within specifications.

Permeable UK Granite Is Good News for Geothermal Energy

In mid-February, the Geological Society of London raised the hopes of those promoting geothermal energy when results of exploratory drilling in Weardale, County Durham, revealed record levels of permeability in granite. Although the results are promising for the development of geothermal energy, they may have less welcome implications for the safe disposal of radioactive waste in deep repositories.

U.S. Spins Nuclear Wheels as Other Nations Roll Out New Plants

President Barack Obama’s January State of the Union speech called for incentives to make clean energy profitable — mainly through the construction of a new generation of nuclear power plants. That comment, an apparent effort to reach out to Republican members of Congress, drew furious applause. Within three weeks, the president’s backing of nuclear power had already made a significant impact on the U.S. nuclear sector.

Dish Stirling Solar Plant Debuts

In late January, a 1.5-MW concentrating solar power (CSP) plant began providing power to Salt River Project customers in Greater Phoenix, Ariz. Though small, the plant, developed by Tessera Solar and Stirling Energy Systems (SES), is seen as a prelude to 1,500-MW projects that are due to break ground in California and Texas later this year.

Initial Experiments Meet Requirements for Fusion Ignition

Scientists at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) in California speculate that a prototype nuclear fusion power plant could be operational within a decade, thanks to a test of the world’s largest laser array that confirmed a technique called inertial fusion ignition is feasible. Their first experiments have demonstrated a unique physics effect that bodes well for NIF’s success in generating a self-sustaining nuclear fusion reaction. Fusion energy is what powers the sun and stars.
