Plug your mobile phone into your sweater to re charge it? Sounds bizarre but it could well happen in the not too distant future, as scientists have invented a plastic solar cell that can be woven into a sweater that can turn the sunīs power into electrical energy, even on a cloudy day.
Today we all expect, as a matter of course, to use a telephone that is not plugged into a cable, but we are resigned to the fact that we have to charge the battery every couple of days and always remember to take our battery charger with us when on the move. If this plastic material is woven into a shirt or a sweater it could absorb the invisible infra red from the sun to charge your mobile phone and simultaneously keep you warm using the visible spectrum. The plastic material uses nanotechnology and contains the first solar cells able to harness the sunīs invisible, infrared rays. Plastic solar cells are not new but being able to harness the power in the invisible part of the spectrum is new. This new material is the first plastic composite able to harness the infrared portion. Just imagine how the world we currently live in would be transformed by being able to use the sun for power more efficiently using this technology.
The sun delivers 10,000 times more energy to the Earthīs surface than we consume. If we could cover 0.1 percent of the Earthīs surface with, very efficient, large-area solar cells, we could, in principle, replace all of our energy habits with a source of power which is clean and renewable. The Virtual Keyboard Smart phones and PDAs offer an impressive amount of computing power. But in practical terms, they are not always easy to use. Writing long emails or other documents can, frankly, be a pain.
This revolutionary Virtual Keyboard (VKB) uses the latest infrared & laser technology to project a full-size keyboard onto any flat surface. The user can type as normal on this virtual keyboard (VKB), enabling them to work quickly and effectively, taking the pain and frustration out of minuscule keyboards and handwriting recognition software. The virtual keyboard even behaves exactly like a real one complete with realistic tapping sounds. You can use the VKB (Virtual PC Keyboard) with both your laptop and PC and with a compatible mobile device, compatible Smartphone and PDA. The device is no larger than a disposable lighter thus easily fits in your pocket. For further information go to our website www.e3s.com for brochures and links.
