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.
In the Caribbean, the options are essentially the same, but practically wind and solar energy are the most promising short term solutions.
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.
Spring has been a busy period for hydrogen fueling stations, with five stations recently opening worldwide.
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.
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.
A hectare of jatropha yields more than four times as much fuel per hectare as soybean, and more than ten times that of corn.
Only an in-depth, integrated approach to energy access ensures a sustained income rise.
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.
Nanotechnology is undoubtedly one of the key technologies which will influence energy efficiency
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.
The research showed that these panels will work in northern climates. The system was operated over a one month period in February and March when temperatures were at times lower than -20ş C.
This article does not pretend to be an exhaustive dissertation on solar ponds, but it should be enough to wet the appetite of anyone who is searching for a relatively simple almost passive way of collecting the sun's heat and energy.
At the moment, four models have been made: a car, a taxi (5 passengers), a Pick-Up truck and a van. The final selling price will be approximately 5.500 pounds.
The Half Program has proven to be a very good investment - we spent a total of $7,525 for all the energy reduction projects, and we are saving $4,007 per year in energy costs!

Parker Wind Power Solutions - Core technologies to help you harness the windâ€¦ onshore and offshore
Visit Booth #2886 at AWEA Windpower, May 22-25 in Anaheim, CA to see how Parker products, systems and services help you raise performance while reducing risk in wind energy environments. Parker has been on the forefront of windpower for over two decades, with solutions that touch virtually every critical function in the turbine. From integrated lube oil filtration systems and sealing technologies that make drive trains more reliable and bearings operate like new to compact blade pitch actuation systems that maximize rotor efficiency and minimize vibrations in the turbine. Parker has the solutions that make today's advanced and sophisticated wind power plants better and smarter. Case in point? Our high efficiency power conversion systems that deliver optimum power to the grid. While our scalable evaporative cooling system lowers overall system cost with up to 40% higher power throughput.
