Energy Tower: Power for 15 Earths?

Energy Tower: Power for 15 Earths?
Researchers have designed a product that its inventors claim could easily produce between 15 and 20 times the total electricity the world uses today. Not only that, it could also be used as a desalination device and may be able to reverse the effects of global warming. Those are pretty big claims, but the researchers from the Technion - Israel Institute of Science seem confident that the "Energy Tower" could be a major solution to the world's problems. They've been working on the concept since 1983, and together have spent more than 150 man-years researching, designing, testing, and analyzing. As project founder Professor Dan Zaslavsky explains, the Energy Tower works on the basic principle of convection: hot air rises and cold air falls. The 3,000-foot tall tower, with a diameter of 1200 feet, would take advantage of the heavy falling weight of cold air. Any kind of water - from a sea or drainage ditch - would be added to the top of the tower. Via: Israel21c Related:  Green initiatives

Think Big! Arizona Solar Tower 2X Taller Than the Empire State Building Will Produce 200 Megawatts Image: Enviromission 2625 Feet Tall! Solar towers, which are kind of big funnels that generate electricity by using the fact that hot air rises, are too often forgotten when we discuss solar energy. How a Solar Tower Works There are 3 main components. -The Tower The Tower is the thermal engine of the Solar Tower technology. -The Canopy The canopy converts a large percentage of the insulation into heat, which in turn, heats the air trapped under the canopy roof or is stored in the ground soil thermal storage system. -The Turbines The Turbines transform the energy from the heat and pressure of the air into mechanical energy and the generator converts it into electricity. The beauty is that there are very few moving parts, so it doesn't cost much to operate, and because the area under the canopy heats up so much and there's still going to be a significant temperature differential between the bottom and the top of the tower, it can continue to produce power at night.

The Copenhagen Diagnosis World's First Building-Integrated Wind Turbines Three wind turbine blades have been successfully installed on the Bahrain World Trade Center, a twin skyscraper complex. This is the first time that a commercial development has integrated large-scale wind turbines within its design to harness the power of the wind. The three massive turbines, measuring 29 meters in diameter, are supported by bridges spanning between the complex's two towers. Through its positioning and the unique aerodynamic design of the towers, the prevailing on-shore Gulf breeze is funneled into the path of the turbines, helping to create power generation efficiency. Once operational, the wind turbines will deliver approximately 11-15% of the energy needs of the building, or 1100 to 1300 megawatt-hours per year -- enough to provide light in 300 homes for over a year.

Advertisement Super Cheap Solar Cells Just Got Cheaper, Switch Gold For Nickel One of the major drawbacks of most renewable energy sources is high cost. In order to see a huge rise in the use of renewable energy sources, prices must come down. In the world of solar there have recently been some major breakthroughs in cost advantages and efficiency increases. Scientists at the University of Toronto in Canada have come up with a way to reduce colloidal quantum dot solar cell prices by up to 80%, by swapping out costly conductive gold for cheap nickel. Quantum dot solar cells consist of a silicon substrate that has a thin film coating of nanocrystals — or quantum dots. Gold was previously used as the conductive material in the cells and when scientists tried to switch the gold out for nickel the nickel formed new particles with the quantum dots that weren’t able to capture energy.

EcoGeek - Brains for the Earth Windbelt Micro-wind, 10 Times Cheaper Wind Energy!! [Run time: 2:05 min] I hope you enjoy this short video of Shawn Frayne, a young inventor that has created this device to generate, on the micro-scale, energy for LED lights and radios in developing countries. This is the first approach that uses aeroelastic flutter to create super cheap electricity. We’re talking about changing the way wind energy is harvested and captured. Frayne won a 2007 Breakthrough Award from Popular Mechanics, and he deserves it. UPDATE: EcoGeek reports that Shawn Frayne has launched the website for Humdinger Wind Energy. Here’s a different video of Shawn Frayne talking about the Windbelt technology. Article tags: alternative energy, video

Ending Ageing — An update from Aubrey de Grey's co-author (Includes interview) Ageing - or aging as they say in the US, is something we all have to do, but only if we're lucky. And here to talk about it is... MR: My name is Michael Rae; I'm one of Dr de Grey's research assistants, and coauthor of his book, Ending Aging . Gerontologist and Othello player extraordinaire Aubrey de Grey and two members of his team at SENS, including co-author Michael Rae. The same trick has been used to generate a functional (although so far short-lived) set of lungs and a liver.

Turn Steel Into Solar Panels With Photovoltaic Spray Paint No, it's not a joke or a crazy awesome futuristic concept . It's real. Tata Steel Europe (formerly Corus) and Swansea University in Wales, UK are collaborating to develop a spray-on technology that would transform steel sheets into solar panels. Earth and Industry says , The technology has significant applications since it is highly efficient even in diffused sunlight. If extended, the technology can find its way to the automobile industry where photo-sensitive dyes can be applied to cars to generate electricity to split water into hydrogen and oxygen for fuel cells. Imagine the applications of such a product. The power options could be limitless. And if you think the spray-on solar technology is years away from reality, think again. The technology gains significance because the process of 'printing' these dyes on the steel sheets has already been mastered by Tata's European subsidiary Corus which is working on a new plant for the production of these steel sheets.
