Use of magma as a source of geothermal energy, toward the volcanic power supply?
Use of magma to generate electricity is a much more ambitious (and dangerous) that the concept that underlying existing geothermal plants. After a recent preliminary study, now reached conclusions focused on practical use of artificially dug wells that reach a mass of magma located deep underground.
250 million for vehicle projects decarbonation
France – Luc Chatel, Secretary of State for Industry, announced Monday a call for projects with a budget of 250 million euros to finance the development of vehicles decarbonation.The call for projects concerning electric and hybrid cars rechargeable like their equipment.250 million euros will be allocated in the form of soft loans limited to 50% of the investment and the total by the end of 2010.”These loans, at a time when it is very difficult to obtain finance on the market, can have a real impact and a real effective,” said Secretary of State for Industry.
Lyon: students present the first solar airship
Lyon, France – At the 48th Salon du Bourget aerospace, students from INSA Lyon prepare to unveil the first airship powered by solar energy.
This summer he will conduct its first manned flight, over the Channel.
A collaboration of about thirty students from large schools such as technical schools, the solar airship named Nephelios show will be presented to the Air Show to be held from 15 to 21 June.
Manufacture of Gasoline with Yeast and Bacteria
According to Christopher Voigt, a synthetic biologist at the University of California, San Francisco, where we combine a bit of brewer’s yeast with a gene from a salt marsh plant and grow a little-known bacterium found in a French site, so we have a cheap and to drive our cars rolling.
In theory, biofuels derived from plants can be a neutral source of energy, but many of them moving to food crops.Manufactured from cellulose-a structural material in abundant crop residues and grass, can solve this problem,but there is little effective processes for doing so.
Solar Clothing
During a long walk listening to you music on your mp3 player and then the battery runs out.Now, according to the article published in The Guardian, a team of scientists is working on a solution that would continue to operate, making the battery user through clothing with solar energy.
It’s flexible solar cells that can be incorporated into jackets, trousers and any other item of clothing and, according to Fujitsu Siemens, will be ready in barely a year.The cells work like solar panels, converting light into energy.The user could plug in devices like mobile phones or mp3 players in a special pocket of the garment, which in turn is connected to solar cells.
Fuel From Algae
Solazyme, a start-up in South San Francisco, California, has developed a new process that can convert biomass into fuel using different varieties of seaweed.This new method, which allows the manufacture of a fuel as cheaply as oil from algae, biofuels could lead to more affordable.
Late last year, Solazyme received a grant of $ 2 million from the National Institute of Standards and Technology to develop a substitute for crude oil based on algae.The company, which in January announced a development and testing agreement with Chevron, recently demonstrated the operation of its fuel from algae in a diesel car.
Portable Solar Power
A molchila with solar panels that can recharge all types of small appliances is now available in the market.Voltaic It costs $ 229 .
The molchila is a small size, ideal for wear during an outing.The solar panels are in a zippered pocket, a kit with batteries, a terminal, a few pockets for appliances that need to be recharged, and plugs.The cables are within the molchila to facilitate recharging of different devices at once. According Voltaic Systems, molchila can recharge a mobile phone or cell phone in 4 to 6 hours on a sunny day.You can also recharge digital cameras, MP3, GPS, PDAs, iPods etc.
Mobile phones with Solar Energy
Recent advances in nanotechnology have made possible the manufacture of flexible solar cells and low cost.So much so that soon mobile phones or mobile phones may be recharged with solar energy.
According to MIT Technology Review, Scientific Konark Technologies in Lowell, MA, have invented a new form of solar cell which is composed of thin strips of plastic about 10 cm. by 5cm (similar to the videotape) that can convert light into electricity.Joining a few of these strips, you can generate power capable of running a small fan.
Solar Cells
StarSolar, a breakthrough technology company established in Cambridge, Massachusetts, seeks to capture and use photons that usually pass through the solar cells without generating electricity. According to the company, their designs will halve the cost of solar cells, while retaining its effectiveness, something that equipararía solar energy to electricity price.
Bacteria that Generate Energy with Light
According to an article published on March 26, 2007 in Technology Review, MIT’s new research has found that a set of genes found in marine micro-organisms could provide a common bacteria the ability to generate energy from light.
With a simple modification, the bacterium E.coli, often used in laboratories, could pass for your cellular energy in sugar to a diet of light, a breakthrough that could be used in improving the production of biofuels, pharmaceuticals and other chemicals.
