Concentrated Solar For Hawaii

The collector being enclosed or open faced would require surface care and significant weekly cleaning. Sopogy's panels would park at night, meaning the collector surfaces are protected so as not to be exposed.

Electric Bikes and Large E-scooters

E-machines have no more maintenance than a bicycle. They are simple, efficient, safe and fun to ride

Environmental Policy May Contain Traces of Nuts

Should we choose to have 20% of our power production ideologically clean, or 80% of our electricity needs atmospherically clean? The answer is: we should do both.

From the Earth to the Moon: Cash or Charge

If successful, the SS2 and the WK2 could pave the way for a much larger craft that could ferry several hundred passengers into low orbital space and the land in another country or continent without the need for expensive jet fuel.

GREEN ENERGY OPTIONS IN THE CARIBBEAN

In the Caribbean, the options are essentially the same, but practically wind and solar energy are the most promising short term solutions.

Greenroofs benefits outweigh costs, even in desert environment.

The only severe downsides of having greenroofs in a desert climate are cost of installing it, and then the water use for irrigation. But as we'll see, the water needed for irrigation is more than covered by available greywater.

Hydrogen stations are springing up everywhere!

Spring has been a busy period for hydrogen fueling stations, with five stations recently opening worldwide.

INTERVIEW WITH RICHARD J. KASPER OF GEM

Today, over 40 of the 50 United States have enacted laws that allow for NEVs to be driven on city streets. As the awareness of NEVs becomes more widespread, and the benefits of owning them and driving them realized, we see significant market potential in the future.

KiteBoating in Hawaii

The potential kite power vessels will have many applications for fishing, powering ferryboats, and barges, to providing emergency power to motorboats. The sky is the limit for the future of kiteboating; the ocean is waiting.

Plant Jatropha - Go Green - Reduce Poverty

A hectare of jatropha yields more than four times as much fuel per hectare as soybean, and more than ten times that of corn.

Putting Down Roots

Only an in-depth, integrated approach to energy access ensures a sustained income rise.

Random Thoughts from this Year's Renewable Energy Fair

Reducing one's energy overhead costs relatively little and produces a revenue stream that appreciates over time. Replacing one's energy infrastructure with on-site renewable systems, in contrast, will require a sizable up-front financial commitment relative to what it will produce over time.

Renewable Energy Markets Worldwide 2015 Driven by Climate Change

Nanotechnology is undoubtedly one of the key technologies which will influence energy efficiency

SMALL ELECTRIC VEHICLES IMPROVE LIVABILITY

A second generation of Personal Vehicles is being created with performance and range similar to its ancestors, while meeting the priorities of a society re-defining the meaning of community.
