E-machines have no more maintenance than a bicycle. They are simple, efficient, safe and fun to ride
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.
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.
Records 1621 to 1635 of 2027
Soiling of the panel glass is one of the major problems in the rapidly expanding solar energy market, with the attendant loss of efficiency and reduction in performance ratios. Now, there's a new, simple and very cost-effective alternative. Based on Kipp & Zonen's unique Optical Soiling Measurement (OSM) technology, DustIQ can be easily added to new or existing solar arrays and integrated into plant management systems. The unit is mounted to the frame of a PV panel and does not need sunlight to operate. It continuously measures the transmission loss through glass caused by soiling, so that the reduction in light reaching the solar cells can be calculated.
