Photovoltaic Quality & Safety Testing: DOE Presentation Reveals 13 Years of Successes & Failures

Figures from 13 years of solar technology testing - including the top three quality failures and strongest influences of new manufacturers on module design - show some photovoltaic (PV) modules required a tune-up to pass international qualification standards.

First U.S. wave-power farm

Construction has begun off Oregon's coast on the first commercial U.S. wave-energy farm, planned to supply power to about 400 homes, according to a USA TODAY report. Wave power draws from the energy of ocean surface waves. A float on a buoy rises and falls with the waves, driving a plunger connected to a hydraulic pump that converts the vertical movement into electricity. The first buoy will measure 150 feet tall by 40 feet wide, weigh 200 tons and cost $4 million, according to Phil Pellegrino, spokesman for New Jersey-based developer Ocean Power Technologies, which is developing the project.

Significant Legal Issues For Landowners And Operators Of Wind Projects

Significant issues for the operator may include the operator's right to enter onto the land and monitor the land for wind potential before an agreement is executed with the landowner. This right is typically set forth in an option granted to the operator for a period lasting anywhere from two to ten years, in exchange for a fee paid to the landowner, allowing the operator adequate time to carry out a wind study to ascertain whether the land is a good candidate for a wind project.

Porsche 911 GT3 R Hybrid

The innovative hybrid technology featured in the car has been developed especially for racing, standing out significantly in its configuration and components from conventional hybrid systems. In this case, electrical front axle drive with two electric motors developing 60 kW each supplements the 480-bhp four-litre flat-six at the rear of the 911 GT3 R Hybrid. A further significant point is that instead of the usual batteries in a hybrid road car, an electrical flywheel power generator fitted in the interior next to the driver delivers energy to the electric motors. The flywheel generator itself is an electric motor with its rotor spinning at speeds of up to 40,000 rpm, storing energy mechanically as rotation energy.

PV Certification Improving the Quality of Renewable Technology

Poor-quality solar energy equipment could flood the U.S. market without the safeguard of third-party testing and certification. Newly announced testing and certification recommendations by Solar America Board for Codes and Standards (Solar ABCs) aim to protect consumers and businesses alike.
