Transmitting Power Over the Air

 Korean Scientists have demonstrated the transmission of power via lasers over a distance of 30m. A laser is pointed at a receiver which converts it to about 85mw of electrical power.

Growing soil erosion around the world a problem

Soil Erosion what is it why does it effect me? Soil erosion is the loss of top soil from the ground and is a natural occurence. Step in the human race!                Land is being cleared for farming through deforestation and plouging,this cause the soil to be washed away by the rain and blown by the wind. Leave a field with no plants and it will erode quickly. Every minute we loss 30 football fields worth of top soil to the seas and rivers, It take 1,000 years to generate three centimeters of top soil.           Some crops can not  hold the soil in place thus increasing erosion on normal arable land these include coffee,  cotton,   wheat, palm oil,  soybean  With an incresing global population this is a problem that we could well do without and is not given enough attention by the goverments of the world.

Wamer Seas drive melting Ice in the Antartic

Photograph by Corbis Rapidly melting Antarctic Ice caps are dropping mount everest blocks of ice into the sea every two years a study reports. The western ice sheet itself holds enough ice to raise the sea level by 5 meters. Use the sea level map at  Flood Maps    to see how this would effect you .

Carbon Lift

Image Kone A new elevator made from carbon fibre has been developed to take you even higher in one go. Conventional lifts where limited to 500 meters due to the weight of the lift gear. Now new lift gear made from carbon  fibre will take you up to 1 Kilometre without stopping. The lift developed by  Kone’s is also more energy efficient due to being lighter.
