Almost-Overunity Motor Generator Recovers Back EMF
Every electric motor has a force that opposes the propelling electromagnetic field inside it, called "Back EMF". Thane Heins succeeded to recover this back-EMF and, instead of letting it cause resistance, he transformed it into useful power. This claim has brought him opposition for many years from the scientific community, because it seems to violate Lenz's law.
Oceanlinx Harvesting Australian Wave Power Very Efficiently
Oceanlinx has started since few years ago a renewable energy project based on wave energy. The device is a Oscillating Water Column which was first deployed in 2005 but this had undergone planned refurbishment and modifications this year. Today the device is again up and running and can generate from 100 Kw up to 1.5 MW, depending on the waves and requirements from consumers.
Scientist Mimicking Green Plants to Create Efficient Solar Cells
Although no specific details are given, from an article published in Science Daily it seems that prof. Pavlos Lagoudakis at the University of Southampton has developed a new method of converting light into electricity using a process found in green plants' photosynthesis.
ZTE Coral 200: The $40 Eco-Friendly Solar Powered Phone
Until now many of us know about Samsung's environment friendly phone, Blue Earth. It is made of recycled plastic, and the difference between it and other devices is that it can recharge itself, as it is equipped with solar panels.

First American GM Hybrid Sold in the US Cheaper than Prius
Saturn Aura is going to be the first hybrid GM is launching on the US market, as a direct competitor for Toyota Prius. Only in 2006, Toyota sold 107,000 Prius units, creating a big popularity of the hybrid.
DIY: Easily Convert Any Bicycle Into Electric With GreenWheel
MIT engineers have been developing and are now testing an upgrade to the old bicycle that can be easily installed and that can transform your foot-powered 2-wheeler into a full-electric vehicle (or hybrid, if you use your own force).
Tazzari Zero EV: The Electric City Sports Car Beast
Tazzari Group developed a simple but in the same time elegant electric vehicle Tazzari Zero EV. The vehicle wants to qualify as a sports-car for the city, being very light, with high torques and fully recyclable.
Do Africans Plan to Produce Energy by Pulling a Roll After Them?
An african inventor, by his name Cedrick Ngalande, has invented a device called the Green Erg, that could harness the pulling force of a person or moving vehicle, and convert some of it into electricity. Though I don't see his invention any soon on any European or US market, it seems some say that it will have a great success in Africa, there where you have to make electricity out of anything.
