Cleantech`s Water Purifier Using Basic Physics Principle
Water purification is not a myth anymore. It can become the reality we've always dreamed of and this with low costs.
Liquid Battery from Molten Salts Invented at MIT
As always, MIT is coming with lots of interesting ideas that often represent really viable ways of improving our energy sources. This time, MIT has come up with a special type of battery never seen before.
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.
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.
Sugar Cube-Sized Solid Oxide Fuel Cell
The world's smallest solid-oxide fuel cell(SOFC), as small as sugar cube, was recently developed by the National Institute of Advanced Industrial Science and Technology (AIST). The sugar cube-sized SOFC is is operable at 550°C.
Scientist Develops Way to Transform CO2 into Methane
Pennsylvania State University researchers found out a way to transform the messy CO2 from the atmosphere into burnable gas, with the help of the Sun. They made use of nanotechnology for this matter, and their results showed a 20 times yield, compared to other findings.
How to Make a $5 Solar Water Heater From Junk Fridge
One simple way of making hot water has been perfected by a blogger on thesietch.org, and it relies on a simple and easy to find piece of junk: an old refrigerator!
Save Fuel With the New Electricity-Producing Shock Absorbers
While some study ways of electronically controlling the shock absorbers and giving you a smooth and steady ride, and others are seeking ways to convert the heat generated by the engine into electricity, a team of undergraduate MIT students invented a shock absorber that harnesses the energy from the very bumps it hits. Several truck manufacturers and the U.S. military have given them attention, and planned to use their technology in their cars.
Butterfly Wings Have Solar Cells Inside: Inspiration for Scientists
The researchers studied the butterfly wings, using them as molds or templates. They made copies of the butterflies' solar collectors, and transferred the light-harvesting structures to classic Grätzel (or dye-sensitized) cells.
