Sewage Could Be a New Way For Cheap Hydrogen

In the field of hydrogen fuel cell production, Oregon State University researchers have discovered that sewage can produce cheap hydrogen. In comparison with traditional electrolysis technology, sewage can produce hydrogen at a lower cost.

New Electric Field Device Reduces Car Fuel Consumption by 20%

Professor Rongija Tao, from Temple University, invented a device that, applied to the vehicle's fuel line, near the injectors, creates an electric field that reduces the fuel's viscosity, so that smaller droplets are injected into the engine, leading to better combustion and increased fuel efficiency as much as 20%.

How a Well Insulated House Saves Hundreds of Dollars a Year

Heating and cooling costs account for between 50% and 70% of all energy costs in the average home, so maximizing the value of the...

Solvatten: Solar Powered Water Purifier for the Poor

While most new inventions are for wealthy people, with some social status, once in a while there are inventions aimed to help the poor and provide the minimal sanitary conditions through simple and inexpensive methods.To get one liter of boiling water you need one kilo of firewood. People living in areas with no safe water usually spend 3-10% of total income/year on water.

Nissan Develops Acceleration Pedal That Pushes Your Foot Back

According to Reuters, Nissan said on Monday that it has invented an accelerator pedal for their future cars that is somehow slapping your foot off it. It can push back on the driver's foot when it detects too much pressure and bad fuel efficiency while accelerating.

New Electron Cooling Discovery to Extract More Energy from Solar Cells

Do you know that electrons can be "cooled"? The cooling of an electron, in lay language, is the transitory state in which the electron passes from a high-oscillation state to a low-oscillation, normal state. The high oscillation state is given by an external stimulus, i.e. electric voltage.

SEADOG Uses Waves' Own Power to Desalinate Sea Water

A company called Renew Blue, Inc. will use wave power to run a desalination plant in Freeport, Texas. The resulted water will be finally put into corn-based biodegradable plastic bottles. The SEADOG power system is made from a buoy which puts in motion a piston mechanism that rotates a water wheel to generate electricity.
