Israel Electric Road: Scientists Turn Traffic Into Power At Haifa's Technion Institute ... - 0 views

  •  
    Scientists in Israel say they have invented a way of turning traffic into electricity. Where does the 'energy' really come from?

Forget Solar Power, Human Power is the Future - 4 views

  •  
    That may be a little aggressive, but Princeton University engineers have developed a device that may change the way that we power many of our smaller gadgets and devices. By using out natural body movement, they have created a small chip that will actually capture and harness that natural energy to create enough energy to power up things such as a cell phone, pacemaker and many other small devices that are electronic.

    Does the paper fully take the quality of various energy carriers into account? Does it merit an article on units & exergy?

BBC News - Harvesting energy: body heat to warm buildings - 2 views

  •  
    "Jernhusen, a real estate company in Stockholm, has found a way to channel the body heat from the hoards of commuters passing through Stockholm's Central Station to warm another building that is just across the road."

10 Best Apocalyptic Vehicles - 0 views

  • Global warming. Faltering economies. Dwindling resources. Mankind has finally set in motion environmental, political and social policies that will surely destroy the world as we know it. Not everyone will fall. Those who survive will roam the scorched wasteland to fend for themselves against the predatory undead while scavenging what they can to survive. The end of days is at hand, and the only question is this: What will you drive when it all comes tumbling down?

How to Make Electricity From Wasted Energy - 0 views

  •  
    Energy efficiency is low hanging fruit in the clean energy movement. Low-grade waste heat may not have the allure of shiny solar panels or a row of wind turbines, but it presents an opportunity that is too good for Michael Newell, CEO of Ener-G-Rotors to pass up. The company is developing a product that generates electricity from low-grade waste heat.

Scaling small energy harvesters for the grid - 2 views

  • there are now other forms of energy harvesters developed initially at the micro level which are now being scaled to produce enough energy to replace or supplement grid power. For example, take the humble bicycle dynamo - based on an electrodynamic energy harvester. The same technology is also used in large scale wind power, but now it has been redesigned to work beyond a rotary means. EnOcean, Germany, offer more than 500 products based on this technology from light switches powered by pressing the switch to wirelessly monitored mouse traps powered by the mouse entering the trap. Re designing the decades old technology is now making other, larger scale applications possible.

Sony Ericsson Says Solar Powered Cell Phones Not So Green - 0 views

  •  
    Solar panels are evolving every day - we know that. As long as people invent ways of being independent to the grid, it's ok, but after a while, they have to be efficient, too. So, for the moment, solar cells in cell phones are like electric cars: they're nice, the concept is beautifully presented, but figures say they're not efficient and practical.

IEEE Spectrum: Silicon Nanowires Turn Heat to Electricity - 0 views

  • Two separate teams, one at Caltech and the other at the University of California, Berkeley, reported that they could increase silicon's ability to convert heat into electric current by as much as 100 times. If they can use what they've learned to improve silicon even further, or translate their findings to other materials, the discovery could lead to new ways to cool computer chips, build refrigerators, or get more power out of car engines.

Capturing the Power of Trillions of Footfalls | EcoGeek | Elizabeth, Power, She, Electr... - 0 views

  • Elizabeth developed the POWERleap as her senior thesis project at the University of Michigan's School of Art and Design. She wanted to design a project that would educate people about their relationship and dependence on energy. Human bodies generate electricity, about 100 watts at rest, which (according to www.elizabethredmond.net) is enough to power the computer I am writing on.
  •  
    A fraction of a small fraction will be small, but as an education project, it serves a similar role as CFL's for example. 100 Watt is heat produced at rest. Producing 100 W of electricity is quite a different thing and is not 'at rest' at all, although it is not a huge physical effort either.
