Le vélomobile : 80 fois plus efficace que la voiture électrique. Le Raht Racer peut atteindre les 110 km/h avec son moteur électrique Rouler à vélo plutôt qu'en voiture : tout le monde est pour, mais qui le fait ?

Le vélomobile : 80 fois plus efficace que la voiture électrique

En pratique, le vent, la pluie et la proximité des autres véhicules ont souvent raison de nos convictions écologistes. Surtout quand il s'agit d'aller loin. Même aux Pays-Bas, paradis de la bicyclette, 77 % des trajets à vélo s'effectuent sur moins de 5 km et seulement 1 % sur plus de 15 km. Alors qu'en France, 26 km séparent en moyenne notre domicile de notre travail, nos Titine seraient-elles donc irremplaçables ? Intérieur d'un vélomobile. Un vélo-mobiliste sans entrainement peut ainsi atteindre facilement les 40 km/h sur du plat. Kris De Decker, auteur du blog Lowtech magazine, affirme détenir la solution : l’assistance électrique. Le seul mode de transport réellement durable Côté autonomie, le vélomobile est encore gagnant. Fondation Keshe : Lancement des Energies Libres !

Vertical-Axis Wind-Turbines Might Increase Wind Power Output. The remote Alaskan village of Igiugig—home to about 50 people—will be the first to demonstrate a new approach to wind power that could boost power output and, its inventors say, just might make it more affordable.

Vertical-Axis Wind-Turbines Might Increase Wind Power Output

For decades, the trend across the wind industry has been to make wind turbines larger and larger—because it has improved efficiency and helped lower costs. John Dabiri, a professor of aeronautical and bioengineering at Caltech, has a heretical idea. He thinks the way to lower the cost of wind power is to use small vertical-axis wind turbines, while using computer models to optimize their arrangement in a wind farm so that each turbine boosts the power output of its neighbors. Dabiri has demonstrated the basic idea at a 24-turbine test plot in southern California.

Grants totaling $6 million from the Gordon and Betty Moore Foundation and the U.S. Dabiri says small, vertical wind turbines have other advantages. The approach, however, faces some challenges. 'Multifab' 3D-prints a record 10 materials at once, no assembly required (w/ Video) 3D printing is great, assuming that all you need to do is print one material for one purpose, and that you're okay with it taking a few tries.

'Multifab' 3D-prints a record 10 materials at once, no assembly required (w/ Video)

But the technology is still far behind where it could be in reliably producing a variety of useful objects, with no assembly required, at a cost that doesn't make you want to poke your eyes out with a 3D-printed fork. In recent years companies have been working to tackle some of these challenges with "multi-material" 3D printers that can fabricate many different functional items. Such printers, however, have traditionally been limited to three materials at a time, cost as much as $250,000 each, and still require a fair amount of human intervention. But this week researchers at MIT's Computer Science and Artificial Intelligence Lab (CSAIL) say that they've found a way to make a better, cheaper, more user-friendly printer.

Bug-killing book pages clean murky drinking water. A book with pages that can be torn out to filter drinking water has proved effective in its first field trials.

Bug-killing book pages clean murky drinking water

The "drinkable book" combines treated paper with printed information on how and why water should be filtered. Its pages contain nanoparticles of silver or copper, which kill bacteria in the water as it passes through. In trials at 25 contaminated water sources in South Africa, Ghana and Bangladesh, the paper successfully removed more than 99% of bacteria.

The resulting levels of contamination are similar to US tap water, the researchers say. Leaving Facebook... Pod-like Survival Capsule protects those who can't flee a tsunami.

U.S. Army develops new solar cells that are 1,000 times thinner than current technology. Military research leads to a lot of cool technological advancements that can benefit the public as much as the troops.

United States Army researchers have been working on improved solar technology, and they have developed a tiny photovoltaic solar cell that is substantially smaller and more cost effective than any other solar cell on the market. The new design has won the Army a patent, and the inventors are calling it a “breakthrough” in clean energy. At the heart of advancements in solar power technology is the drive to make solar cells smaller, lighter, and more efficient. It’s already possible to print paper-thin solar cells, but the Army’s latest patent is for solar cells just a fraction of that thickness, which is tough to imagine. Transparent Aluminum is On Its Way - Thanks, Star Trek! » Krypton Radio.

No fewer than two separate companies are now working on manufacturing techniques for high grade transparent aluminum. For a while, they were dancing around using the term “transparent aluminum”, because the various means of producing a transparent metal so far all use aluminum but not as the primary element. The idea of using the already popularized term “transparent aluminum” was too seductive to be ignored; transparent aluminum it is. According to Star Trek canon, transparent aluminum is used on everything on a starship that has to be exposed to space and still pass light. Portals and windows would all be made of it. Plastic cloud pods naturally cool the landscape with the power of evaporation.

An immensely powerful yet invisible force pulls water from Earth to the top of the tallest redwood and delivers snow to the tops of the Himalayas.

Yet despite the power of evaporating water, its potential to propel self-sufficient devices or produce electricity has remained largely untapped -- until now. In the June 16 online issue of Nature Communications, Columbia University scientists report the development of two novel devices that derive power directly from evaporation -- a floating, piston-driven engine that generates electricity causing a light to flash, and a rotary engine that drives a miniature car. When evaporation energy is scaled up, the researchers predict, it could one day produce electricity from giant floating power generators that sit on bays or reservoirs, or from huge rotating machines akin to wind turbines that sit above water, said Ozgur Sahin, Ph.D., an associate professor of biological sciences and physics at Columbia University and the paper's lead author.

These new devices generate renewable energy from evaporation. Evaporation is a key component of the Earth’s water cycle, and one of the world’s most dominant forms of energy transfer—and it’s believed that as the climate warms, evaporation rates will increase and result in more moisture in the lower atmosphere. Yet the power of evaporation has rarely, if ever, been utilized for energy generation. L'Ampoule au Graphène: Durée de vie 25 ans, encore moins d'énergie que la L.E.D ! - (re)Vivre à la Campagne ...
