Green, leafy spinach may soon power cellphones and laptops

For the first time, MIT researchers have incorporated a plant’s ability to convert sunlight to energy into a solid-state electronic “spinach sandwich” device that may one day power laptops and cell phones.

At the heart of the device is a protein complex dubbed Photosystem I (PSI). Derived from spinach chloroplasts, PSI is 10 to 20 nanometers wide. Around 100,000 of them would fit on the head of a pin. “They are the smallest electronic circuits I know of,” said researcher Marc A. Bal

Wastewater could treat itself, power city

U of T research offers hope for environment

The energy stored in Toronto’s municipal wastewater could be harnessed to run water treatment facilities and contribute power to the city grid, says new U of T research. The study, published in the August issue of the Journal of Energy Engineering, is the first to measure the energy content of the raw municipal wastewater in the Ashbridges Bay, North Toronto, Highland Creek and Humber plants. The research revealed that the wastewater conta

Have you run out of energy?

Imagine having your own annual greenhouse gas allowance which you ’spend’ each time you fill up with petrol or pay an electric or gas bill. It sounds like a scene from a futuristic movie, but this scenario could really happen in the next few years according to researchers at the UK’s Tyndall Centre for Climate Change Prediction.

Dr Kevin Anderson and Richard Starkey are investigating a system of personal trading for carbon emissions. Instead of people being forced to pay a carbo

Carbon nanotube oscillator might weigh a single atom

Using a carbon nanotube, Cornell University researchers have produced a tiny electromechanical oscillator that might be capable of weighing a single atom. The device, perhaps the smallest of its kind ever produced, can be tuned across a wide range of radio frequencies, and one day might replace bulky power-hungry elements in electronic circuits.

Recent research in nanoelectromechanical systems (NEMS) has focused on vibrating silicon rods so small that they oscillate at radio frequenc

Methane in deep earth: A possible new source of energy

Untapped reserves of methane, the main component in natural gas, may be found deep in Earth’s crust, according to a recently released report* in the Proceedings of the National Academy of Sciences of the United States of America (PNAS). These reserves could be a virtually inexhaustible source of energy for future generations.

Major grant drives forward cost efficient solar power

Whether the search for alternative energy sources is driven by our concern about global fossil fuel supplies or over the atmospheric effects of burning of fossil fuels, the government has laid out its aim to cut carbon dioxide emissions by 60% of 1990 levels by 2050, and aims to over- achieve its goal of sourcing 10% of energy from renewables by 2010.

In a significant step to achieve these targets, an enormous £4.5 million award has been made under the UK SuperGen programme to drive
