Carbon nanotube-based photodiode

Cornell researchers fabricated, tested and measured a simple solar cell called a photodiode, formed from an individual carbon nanotube.  Using a carbon nanotube instead of traditional silicon, Cornell researchers have created the basic elements of a solar cell that hopefully will lead to much more efficient ways of converting light to electricity than now used in calculators and on rooftops.

‘Flash-Frying’ Coal Underground To Provide A Green Source Of Energy

coal2_1455603c

A project is taking shape that could offer an affordable means of reaching billions of tons of deep-lying coal deposits without causing irreparable harm to the environment.

Coal has become the ugly sister of power sources, condemned as old-fashioned, ultra-polluting and excessively costly to mine, given that we have exhausted the most easily accessible supplies.

New Oyster Machine To Harvest Wave Power

oyster

The Oyster concept for transforming wave power to onshore electricity.

A giant new machine called’ Oyster’ designed to harness the power of ocean waves and turn it into ‘green’ electricity is being installed on the seabed off the Atlantic shores of the Orkney Islands. In autumn 2009 it will undergo demonstration trials to prove whether its innovative technology could lead to a commercial source of renewable energy for use in seashores around the world.

Air-Fueled Battery Lasts 10 Times Longer

Air-Fueled Battery Lasts 10 Times Longer

Oxygen drawn from the air reacts within the porous carbon to release the electrical charge in this lithium-air battery. 

A new type of air-fueled battery could give up to ten times the energy storage of designs currently available.  This step-change in capacity could pave the way for a new generation of electric cars, mobile phones and laptops.

Amazing Vertical Farm For Vancouver

Amazing Vertical Farm For Vancouver

Vertical farm for Vancouver’s 2030 Challenge 

Vertical farms are one of our favorite future-forward concepts for creating sustainable cities. Providing locally-grown produce and food will not only help us reduce our carbon emissions significantly, but also help us become healthier. Romses Architects recently came up with an amazing concept for a vertical farm in Vancouver as part of the City’s 2030 Challenge. Complete with a tower for growing fruits and vegetables, a livestock grazing plane, a boutique dairy farm, commercial space, transit lines, renewable energy and more, the Harvest Green Tower has the potential to be a food growing, energy producing, living, breathing sustainable transit hub.

Harnessing Direct Solar Power To Propel Tiny Nanomaterial Machines

Harnessing Direct Solar Power

A four-finned rotor (center) floating on a pool of water spins when exposed to sunlight.

The sun is the most abundant source of renewable energy. But all the technologies that capitalize on sunlight, including photovoltaics and biofuels, require intermediate steps and infrastructure to turn the sun’s rays into something that can be used to perform work in a machine. Researchers at the University of California, Berkeley, are using carbon nanotubes to build small, simple waterborne machines propelled directly by sunlight. In theory, they say, these machines could be scaled up to make energy-generating pumps directly powered by the sun.
