Kinesis has developed very good product for charging mobile devices that can charge many portable devices like ipod, mobile, camera, etc, it uses both wind and solar energy. leaving the device all day in wind can charge 20 hours of internal battery and in direct sunlight could charge upto 8 hours. Internal battery power could be transferred to music player, phone,etc via USB port.

Under water tidal power generation is not a new technology but it is improving day by day recently a group of engineers of oxford developed new design called Transverse Horizontal Axis Water Turbine which they think is more powerful and efficient than resent technology, according to them THAWT's ( Transverse Horizontal Axis Water Turbine ) manufacturing cost is 60% lower and has 40% lower maintenance cost.THAWT uses different technique than recent technology which has works as wind mill underwater, THAWT uses cylindrical rotors that rolls around its long axis with the flow of water. According to the engineer THAWT could produce 12 megawatts of energy which is enough for 12000 homes that recent one.
But even though with their achievement they are concerned of underwater ecology,Steph Merry, head of Renewable energy has told that in there design they have taken full consideration of climate change and the requirement of safeguarding the ecology of tidal areas.[Guardian.co.uk]
Future of our energy needs could be satisfied by the hot magma in our earth Australian study says that 1% of Australia's geothermal power potential could provide the nation with a whopping 26,000 years of energy.
It could relay works it could solve our big need of energy. Australian Geothermal Energy Association says that this could work my drilling 2.8 miles into the surface of the earth into the hot magma. This project could cost $10.45 billion but this is only one them cost after this is done we could get green energy for atleast 26,000 years.[DVICE]
Cool Earth has developed new solar power technology which could be the lightest solar concentrator it weight just 20 pound. This power plant is inflatable with transparent plastic on the top and reflective plastic on the bottom which concentrate sunlight on PV cell placed at the focal point.
The company is trying to reduce its cost and clamming that one balloon can generate 500 watts which enough for chilling our bear. let us see when this technology is comes in the market in future we cold see our house or office electricity is produce by this type of balloon flying in garden on terace.

Australian researchers has developed a cathode built fuel cells which are cheaper than traditional fuel cells.
Researchers of Australian Center of Excellence for Electromaterials Science has developed this cell with help of materials engineer professor Maria Forsythe.
Traditional fuel cells which convert hydrogen and oxygen to electricity which runs the car are made of cathode which has expensive platinum nanoparticles which can lose effectiveness by clumping togeather or becoming poisoned by carbon monoxide and they cost $3500 to $4000 for a single passenger car it covers almost cost of fuel cell.
New cathode which are developed from conducting polymer is a special plastic that can conduct electricity called poly or PEDOT.
This cathode materials easy to made are even cheaper almost several hundred dollars it is also stable than platinum which is affected by carbon monoxide.
This cathode material can also be used in zinc air batteries but it is a testing procedure which could be used in storing electricity in cars.[abc.net]
