Cheap Hydrogen from Sunlight and Water

Cheap Hydrogen from Sunlight and Water | TechWatch | Scoop.it

Stanford researchers say new materials could help lower the cost of producing fuel with solar energy.

 

By making a solar photovoltaic material more resilient, researchers may have found a way to make artificial photosynthesis—that is, using sunlight to make fuel—cheap enough to compete with fossil fuels.

Power Amplifier Breakthrough Promises To Double Smartphone Battery Life

Power Amplifier Breakthrough Promises To Double Smartphone Battery Life | TechWatch | Scoop.it

MIT spinoff company, Eta Devices has achieved a breakthrough in the power amplifiers and promises that it would almost double your smartphone battery life. What this means is that your iPhone will actually last longer than 10 hours and your Android will live for more than a day even for the power users. The company says that they’ll begin the commercial production in 2013 and will demo it at the Mobile World Congress in Spain. The company wants to aim the developing world first but the technology would definitely be adapted my all the mobile hardware makers.

India plans 'safer' nuclear plant powered by thorium

India plans 'safer' nuclear plant powered by thorium | TechWatch | Scoop.it

The development of workable and large-scale thorium reactors has for decades been a dream for nuclear engineers, while for environmentalists it has become a major hope as an alternative to fossil fuels. Proponents say the fuel has considerable advantages over uranium. Thorium is more abundant and exploiting it does not involve release of large quantities of carbon dioxide, making it less dangerous for the climate than fossil fuels like coal and oil.

While scientists race to develop a technology, probably nuclear-based, that can slake our energy thirst without a huge environmental cost, it would be folly to wait that long to tackle carbon emissions.

Nanoparticles Make Steam without Bringing Water to a Boil

Nanoparticles Make Steam without Bringing Water to a Boil | TechWatch | Scoop.it

A new trick could reduce the energy needed for many industrial processes and make solar thermal energy much cheaper.

 

Steam is a key ingredient in a wide range of industrial and commercial processes—including electricity generation, water purification, alcohol distillation, and medical equipment sterilization.

 

Generating that steam, however, typically requires vast amounts of energy to heat and eventually boil water or another fluid. Now researchers at Rice University have found a shortcut. Using light-absorbing nanoparticles suspended in water, the group was able to turn the water molecules surrounding the nanoparticles into steam while scarcely raising the temperature of the remaining water. The trick could dramatically reduce the cost of many steam-reliant processes.

Pioneering scientists turn fresh air into petrol in massive boost in fight against energy crisis

Pioneering scientists turn fresh air into petrol in massive boost in fight against energy crisis | TechWatch | Scoop.it

Is scientific breakthrough a milestone on the road to clean energy?

 

A small British company has produced the first "petrol from air" using a revolutionary technology that promises to solve the energy crisis as well as helping to curb global warming by removing carbon dioxide from the atmosphere.
