Israeli scientists have developed a method to generate electricity by using the cars passing. In addition, they announced that next month will inaugurate two such highways that will generate energy.
Experts say that the cars which are moving on a distance of one kilometer can generate over 640 kilowatts, enough energy to power 12 small [...]

Tokyo’s subway stations are using the  people steps to light up electronic signboards and ticket machines.
The experiments have started this week at two of the most crowded subway stations from the Japanese capital. Thus, in front of the subway stations, were mounted special plates that trigger light vibrations that can be stored as energy.

A professor at Texas A&M University, Tahir Cagin and his partners have discovered that the sound waves produced by the user could power cell phones.
They found a new material that could convert energy at a 100 percent increase when manufactured at approximately 21 nanometers in thickness.

The motion can be a valuable source of energy, with the help of a small generators, even the legs movement can produce electricity. The procedure is called “harvest energy” and is tested at this moment on discos floors.
According to researchers, the technology will soon allow us to charge through movement, the iPods and [...]

A futuristic mountain hideaway, the alpine capsule, was designed by Ross Lovegrove to be one with nature. The capsule generates energy by means of solar panels and of a wind turbine, which is set on the vertical axle.
The capsule has a diameter of 8 meters and a double wrapped glass which reflects the environment elements. [...]

An environment-friendly robot, and multifunctional, which is powered by solar energy, was created by a group of scientists from the Louisiana University. The robot, named “Agbot“, has been developed with selectable software options and with two modules for the execution of various tasks.
For recharge, the robot does not need an electricity [...]

In the near future tidal power will become a viable source of renewable energy, but a engineer from University of Michigan discovered a new method to turn river and ocean currents into energy.
This device is called VIVACE ((Vortex Induced Vibrations for Aquatic Clean Energy). In comparison with other water mills and turbines which need [...]

This could be the greatest household device and the best solution to combat water crisis. Based on the same technology of a humidity reduction level installation in a house, the water machine can quickly produce a quantity of water, capturing it from a unlimited source namely the air.
The producer of this machine, the Element [...]

Omron Corp. has created a small prototype generator that can generate electricity from vibrations. The price for this device is nearly $10.36, it is cheap in comparison with what it can do.
The electric current is produce by changing the capacitance depending on the relative position of opposing electrodes. The power that Omron’s generator can produce [...]

In our days every gadget is powered by batteries which are cheap but not very efficient to power electronics. It seems that this problem will be solved because a team of researchers at the Institute of Electronics, Mircorelectronics and Nanotechnology, have discovered micro fuel cells that maintain a good power density at room temperature [...]
