The Shiken Company of Japan is making a prototype solar-powered toothbrush, which causes a chemical reaction in your mouth, with the hopes of improving the elimination of harmful plaque and bacteria.
Dr. Komiyama designed the first model of this type of toothbrush more than 15 years ago: It contained a titanium dioxide rod in the neck of the brush, just below the nylon bristles. Any light falling on the wet rod would release electrons, which would react to the acid typically found in the mouth, helping break down plaque.
The latest model, the Soladey-J3X, works in much in the same way, except that it’s twice as powerful.
The brush also has a solar panel at the base, which transmits electrons to the top of the toothbrush through a wire.
Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory. The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years.Although betavoltaic batteries sound Nuclear they’re not, they’re neither use fission/fusion or chemical processes to produce energy and so (do not produce any radioactive or hazardous waste). Betavoltaics generate power when an electron strikes a particular interface between two layers of material.
The reaction is non-thermal which means laptops and other small devices like mobile phones will run much cooler than with traditional lithium-ion power batteries.
The best part about these cells are when they eventually run out of power they are totally inert and non-toxic, so environmentalists need not fear these high tech scientific wonder batteries. If all goes well plans are for these cells to reach store shelves in about 2 to 3 years.
Update: this turned out to be a hoax.

The way fresh water is supplied to disaster-hit regions could be revolutionised after an Ipswich-based businessman invented a £190 bottle that makes foul-smelling water drinkable in seconds.Michael Pritchard hopes that the bottle could be a life-saver for refugees in disaster regions where access to clean drinking water is vital.
However, the military are already latching on to his idea. Four hours after Mr Pritchard launched his new “Life Saver” bottle at the DESI defence show in London yesterday, he sold out his entire 1,000 stock. “I am bowled over,” he said.
Military chiefs are excited because the bottles, which can distill either 4,000 litres or 6,000 litres without changing the filter, will have huge benefits for soldiers who hate drinking iodine-flavoured water.
Conventional filters can cut out bacteria measuring more than 200 nanometres but not viruses, which typically are 25 nanometres long.
Mr Pritchard’s bottle can clean up any water – including faecal matter – using a filter that cuts out anything longer than 15 nanometres, which means that viruses can be filtered out without the use of chemicals.
