The Green Optimistic

It is said that BMW has plans for making full electric vehicles, as new Californian laws force the cars manufacturers to have a significant electric vehicles offer for the market beginning with 2012. They plan to make Li-Ion powered car, with two seats (90% of the time only one is used in practice). The car [...]

A simple redesign of the petrol engine could greatly increase its efficiency when idling or driving at low speeds, as well as reduce the harmful emissions it produces. UK researchers say the new design could even make petrol engines as efficient as diesel ones.
In most petrol engines, fuel is ignited by spark plugs inside cylinders [...]

Here’s an invention that should capture more of the world’s attention, because it can capture more of the world’s winds. Flodesign’s “jet engine”-shaped wind turbine has a slightly different way of seeing the wind flow, and by this it is three to four times more efficient.

This is the Wrightspeed X1, built by Ian Wright (51), the first employee from Tesla Motors. It is a full electric car that can do 0-60mph in about 3 seconds. You wish it could go further than that? Yes, it can go. Future plans are to adopt changes that boost it to about 2seconds for [...]

A group of researchers at the Technical University of Denmark’s project laboratory in Risø have discovered a cooling method that uses magnetic materials instead of electricity, reported daily free newspaper Nyhedsavisen.
The invention will allow for refrigerators to replace existing electric refrigerators in homes and businesses with a fully environmentally friendly power source. Although the first [...]

The ACCESS, as you can see in the title, was developed by Global Research Technologies in Tucson, Arizona. They made a sponge-based system that filters out CO2 from the air and releases clean oxygen.
The system has been made in a smaller-scale unit, that can momentarily capture only less than 100kg of CO2 per day, but [...]

“Enfucell”, a Finland-based company, has developed a flexible thin battery named “SoftBattery”. This 0.3 – 1.0 millimeter battery (1.5 or 3.0 V) can produce a peak electric current of 4mA/cm². Enfucell was founded in 2002, after nearly ten years of research on power sources for low-power application conducted at the Automation Laboratory of the Helsinki [...]

Before going into the details of this invention it would be worthwhile to have an idea of how any generator, even in theory, could be capable of producing a self-sustaining current. This has been clearly explained by Walter M. Elsasser in a Scientific American article (May 1958) titled “The Earth as a Dynamo.”
Elsasser models [...]
