$300 Solarstar Uses the Sun's Heat to Cool Your Home
For all those of you living in a house, with roof and fence, the problem of cooling your residence in the summer is pretty pressing. SolarStar has thought at this niche and built a standalone cooling system, based on the Universe-aged principle of cooling by evaporation of water, getting the hot air out, and putting the colder one in.
Oceanlinx Harvesting Australian Wave Power Very Efficiently
Oceanlinx has started since few years ago a renewable energy project based on wave energy. The device is a Oscillating Water Column which was first deployed in 2005 but this had undergone planned refurbishment and modifications this year. Today the device is again up and running and can generate from 100 Kw up to 1.5 MW, depending on the waves and requirements from consumers.
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.
Small Methanol Fuel Cells Powering Soldiers’ Equipment
Germans have introduced this week a wearable fuel cell which is based on the award-winning unipolar stack technology design. Called Jenny 600S, the fuel cell delivers 25W for up to 20h. Jenny 600S uses replaceable liquid methanol fuel cartridges and can be worn in a vest.
Flat Solar Concentrator: Cheap, Durable, 30% Efficient
Nicolas Morgan, the director of a Toronto-based firm, named "Morgan Solar", helped by his brother, John Paul Morgan, has invented a solar concentrator that gives a different approach to solar concentrators, by making them more appealing both as price and as durability/efficiency.
New Metal-Organic Substance Giving Better Hydrogen Tanks
UK researchers from the University of Nottingham and General Motors from Warren, Michigan, have invented a hydrogen tank material that could replace the current heavy and inefficient pressurized tubes used in today's hydrogen-powered cars.
Cheaper Hydrogen Obtained with Stainless-Steel Brush Cathode
Scientists seem to have found a way to obtain hydrogen from organic matter without the us of the expensive platinum metal. They developed a stainless-steel brush that can help in the microbial electrolysis process reducing the costs in this way up to 80 %.
Genepax (Japanese Water Car Company) Shut to Silence
In June last year, everyone may have heard the buzz about a japanese water car. The buzz was about Genepax, a company from Japan who had claimed that they invented a revolutionary system that splits water into hydrogen and oxygen and then uses a fuel cell to recombine it and generate electricity. That electricity would have driven a car, fact that they demonstrated in front of the press at that time.
Knut Karlsen`s Self-Rechargeable Solar Batteries
I have always liked the idea of rechargeable batteries, because they only cost a fraction of what they're worth as normal batteries, but now I see a different innovation that I had never thought of, even it was obvious: putting solar cells onto the rechargeable battery, and having it charged for free, and most importantly, anywhere!
