The new technology can be used to make guns, or reproduce a set of keys spotted on a table. San Francisco techie Aza Raskin can photograph a key left sitting on a bar, feed the image into his 3D printer and produce a working copy.

IEA - World Energy Outlook

IEA - World Energy Outlook | Energy and Smartcities | Scoop.it

Bringing together the latest data and policy developments, the World Energy Outlook 2013 presents up to date, projections of energy trends through to 2035, fuel by fuel, sector by sector, region by region and scenario by scenario. Oil is analysed in-depth: resources, production, demand, refining and international trade. Energy efficiency is treated in much the same way as conventional fuels: Its prospects and contribution are presented in a dedicated chapter. The report examines the outlook for Brazil's energy sector and provides updates on three key areas of critical importance to energy and climate trends: (i) achieving universal energy access; (ii) developments in subsidies to fossil fuels and renewables; and (iii) the impact of energy use on climate change.

New thermocell technique could harvest power from waste heat at power plants | GigaOM Tech News

New thermocell technique could harvest power from waste heat at power plants | GigaOM Tech News | Energy and Smartcities | Scoop.it

When you drive past a power plant, you may see steam billowing out of its tall stacks. The steam comes from heat generated during the power production process.

 

Lost heat can be thought of as lost energy, and researchers are always looking for ways to instead recycle it into more electricity production. One setup, known as a thermocell, keeps one side of a device cold while the other side is exposed to the heat source. The electricity that begins to flow from the hot to cold sides can then be harvested.

 

Researchers at Monash University in Australia have created a new type of thermocell that is the most efficient yet. It has no carbon emissions and is particularly good at operating from 212 to 392 degrees Fahrenheit — key temperatures for waste heat at facilities like power plants. Their thermocell uses steam to create electricity by exposing one side to the hot steam and the other to cool air or water.

 

“The major benefit of a thermocell is that it harnesses energy that is already readily out there; you’re just harnessing energy that is otherwise lost to surroundings,” PhD student Theodore Abraham said.

 

More traditional thermocells contain water, which boils off at those temperatures. The Monash researchers used a liquid packed with electrolytes, which give it a higher boiling point than water.

 

Thermocells can be used anywhere there is heat, which means they could run off of a car’s tail pipe or even a volcano. They can also run off the human body; one of the finalists at the Google Science Fair this year developed a hand-heat-powered flashlight.

DNA constructs antenna for solar energy

DNA constructs antenna for solar energy | Energy and Smartcities | Scoop.it

Artificial photosynthesis is one of the hot trends in energy research. A large number of the worlds' energy problems could be resolved if it were possible to recreate the ability plants have to transform solar energy into fuel. The Earth receives enough solar energy every hour to satisfy our energy needs for an entire year.

A research team at Chalmers University of Technology has made a nanotechnological breakthrough in the first step required for artificial photosynthesis. The team has demonstrated that it is possible to use self-assembling DNA molecules as scaffolding to create artificial systems that collect light.
