The World Needs Gigawatts not Megawatts

10/01/06, 12:00 AM | Solar & Wind | Analysis and Trends, Photovoltaic Systems

If the Photovoltaics industry is going to play a significant role in worldwide electricity production in the future it all comes down to one word - scalability, the ability of a technology to expand its production capacity to very large sizes, thereby enabling significant cost decreases.

Transportation for a Clean Planet

10/01/06, 12:00 AM | Energy Storage & Grids, Other Energy Topics | Systems, Vehicles | Maxwell Technologies, Inc.

Since successful testing in 2003, ISE has incorporated ultracapacitors into its gasoline, diesel and fuel-cell hybrid electric vehicles with extraordinary results.

Ultracapacitors Double Life of Wave Measurement Buoys

10/01/06, 12:00 AM | Energy Storage & Grids | Technology Discussions, ultracapacitors | Maxwell Technologies, Inc.

By working together with a primary battery, the ultracapacitors have helped to at least double the lifetime, which means that battery life no longer determines the service interval for the buoy.

What's ahead for neighborhood electric vehicles?

10/01/06, 12:00 AM | Solar & Wind | Vehicles

The cost of ownership is one-third and the fuel efficiency is eight times greater when compared to their gasoline-powered counterparts.

Benefits of 24/7 Battery Equalization

08/01/06, 12:00 AM | Solar & Wind | Photovoltaic Systems, Technology Discussions

The equalizer captures energy from batteries with "above average voltage" and dumps that energy into the ones with "below average voltage". When the overachievers try to excel in voltage, their excess energy is used to bring the underachievers up to par.

Can Electricity Save Energy

08/01/06, 12:00 AM | Solar & Wind | Technology Discussions

With the increasing conversion efficiency of electricity in generation, the increasing share of renewable electricity, the high efficiency at the point of use and the potential for system level efficiencies, there is a lot of supporting evidence for a claim that electricity can save energy.

China's Attempt to Balance the Environment and a Rapidly Growing Economy

08/01/06, 12:00 AM | Solar & Wind | Analysis and Trends, Technology Discussions

China may be positioning to change its global image from environmental disasters to an environmental leader, as it was recently recognized as the world leading investor in renewable energy.

E85 - An American Alternative

08/01/06, 12:00 AM | Solar & Wind | Fuels

FFVs can be fueled with 100 percent gasoline up to 85 percent ethanol. Fueling between the two products is driver transparent; no switches need to be flipped or buttons turned.

Editorial Comments

08/01/06, 12:00 AM | Solar & Wind | Vehicles

The H2 Truck is a small vehicle used in many different operation fields including luggage hauling, small commercial vehicles, hospitals and ports.

How Many Energy Slaves Do We Employ?

08/01/06, 12:00 AM | Solar & Wind | Commentary, Opinions and Advice

We use about 128,640 horsepower-hours, or the equivalent of 147 energy slaves working for each of us 24/7, all year long.

Is America ready for Wind Hydrogen?

08/01/06, 12:00 AM | Solar & Wind | Analysis and Trends, Technology Discussions

While flow batteries and other devices can be used to compensate for wind's intermittent output, it's difficult to match the investor and political enthusiasm for hydrogen.

LED Buyer Beware

08/01/06, 12:00 AM | Solar & Wind | Products

If you buy a set of 5 lights for 20 bucks do not expect it to last very long or hold up in extreme conditions. Research what you are going to buy, ask others and make an informed decision.

Micro Thermoelectric Generator Targets ZigBee

08/01/06, 12:00 AM | Solar & Wind | Products, Technology Discussions

The main purpose for developing the Thermo Life is to provide energy harvesting for low-power applications where other technologies would prove inadequate or not possible.

OMG Roofing Products - PowerGrip Universal

Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGrip™ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
