Building a Safer Lithium-Ion Battery

Lithium-ion batteries continue to be the technology of choice for small electronics but, as illustrated here, their continued evolution and the introduction of new large format applications require a closer look at the technology inside the battery.

Direct Methanol Fuel Cells

The direct methanol fuel cell or DMFC is emerging as a future winner in many of the applications that fuel cells can satisfy. DMFC is an important subset of the proton exchange membrane (PEM) fuel cell technology.

Editorial Comments

Imagine if the next Bill Gates is this minute working on a new solar panel design in his garage with a few friends. Let's hope so ... the Alternative Energy Industry needs it's Microsoft.

Energy Security Code of Conduct

All over the world, buildings energy consumption is increasing at a high rate due to the improvement in living standards in developing countries.

It's Not About Being Green

Before you decide to hop onto the green building bandwagon, look towards the final destination. Sustainable, integrated, whole-building design is where to head.

Novel Renewable Energy Products

Virtually, every aspect of our lives in this digitized world needs energy. Alternative energy solutions are now available and more are on their way.

People Planet Profit

The best solutions come from within the community, working on the ground with dedicated entrepreneurs and local groups, who best understand the needs of their community.

Sustainable Patriotism

Do something Sustainable (and thus Patriotic) every day. Take a simple walk instead of taking "a ride," invest in renewable by installing solar or wind, or buying green from your utility, use a compact fluorescent bulb, buy local vegetables, switch to a bio-fuel, trade in that gas hog for something clean and efficient.

The Importance of Watersheds to Your Community

Thinking on the scale of a watershed is useful for environmental work as we can scale things down for planning purposes, and therefore have a greater impact on the environment.

The World Needs Gigawatts not Megawatts

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.

Ultracapacitors Double Life of Wave Measurement Buoys

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?

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

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

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.

RBI Solar - Dahlia Has You Covered

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
