Cheap New Electrochemical Flue Gas Purificaton for Diesel Engines
In Europe half of the cars sold are using diesel engines. The pollution from these cars (carbon particles, nitrogen oxides NOX and unburned hydrocarbons) is to be more strictly restricted by the EU regulations.
Risø Danish Technical University has started a new project to develop an effective method for making diesel engines cleaner.
World's Cheapest "Eco" Bulb That Lasts For 60 Years
The researchers at Cambridge University have invented a new type of "eco" bulb that lasts for 60 years and is three times more efficient than current energy light bulbs. It can reduce the lighting bills by up to 75%.
Plastic Solar Cells: Your Next Gadget’s Cheap Power Source
Portable electronic devices have from now on a new technology invented for making the battery life longer or making them to work completely on solar energy.
The plastic solar cells with eight square inches in size...
Ian`s Solar-Heated Air Balloons Could Harness 500kW Each
How would you like an engine producing your dear electricity? How would you like that engine to have pistons as high as heat-powered balloons? Well, an environmental consultant from Solartran in Brisbane, Australia, by his name Ian Edmonds, has designed such an energy producing "engine" from the classic and romantic air balloon.
Freshwater and Electricity Through Osmosis
Robert McGinnis, Yale doctoral student and Menachem Elimelech, Chair of Chemical and Environmental Engineering, have developed systems that can harness the power of osmosis to transform non-potable water sources like seawater to freshwater and generate in the same time electricity.
New MOSFET-based Device Makes Ultra Low Power Green Sources Usable
A company called Advanced Linead Devices, from Sunnyvale, CA, has designed a MOSFET (a power transistor, you may have one your stereo at home - it basically looks like the picture above) that can open itself to very tiny, small, voltages, and it's called "zero-threshold MOSFET".
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.
DIY: How to Build the Simplest Electric Motor in Your Kitchen (video)
Electric motors have simple designs, are easy to operate and have a great resistance to various environments. That's why they are to be chosen as alternative to internal combustion engines. This is a trivial experiment showing how you can feel you made a real electric motor yourself. Just for fun.
Wastewater Mixed With Petroleum Could Reduce Emissions by 84%
Taiwanese scientists discovered that a new fuel can be made by combining industrial wastewater and petroleum oil. The new fuel's efficiency is increased by 14% and is a friendly way to treat industrial wastewater as well. The new fuel could eliminate the expensive treatment of industrial air emissions from boilers.
New 13kg Oxford Electric Motor Delivering 3 Times More Power and 97% Efficiency
Following the development of batteries and, generally, electricity storage, the UK-based firm, Isis Innovation Ltd has developed a new revolutionary electric motor that outperforms the old ones by having the materials and a little of the working principles modified inside them.
