Latest Invention: Tea Bag that Uses Nanotechnology to Clean Drinking Water
One of the latest inventions developed by researchers from Stellenbosch University in South Africa is a one of a kind "tea bag" that makes use of nanotechnology to clean drinking water, making it free from contaminants and bacteria.
It would be interesting to note that the "tea bag" is made of the same material that is used to make the actual tea bags. The only difference is that in the Stellenbosch researchers' invention the ingredients are nanoscale fibers and grains of carbon, reports io9.
Both fibers and grains of carbon filter water from all hazardous contaminants. In order to purify the water, the user needs to place the tea bag in the neck of a water bottle. The tea bag filters the water when the person drinks from the bottle.
One bag can be used to filter up to 1 liter of water and it costs less than a half of an American cent.
Loopwing Korea Unveils Solar-Powered Streetlights, Wind Power Generators
Having the goal of reducing the demand for grid electricity, a South Korean company decided to create a new type of streetlights and renewable energy generators.
Looping Korea presented its latest inventions at the Renewable Energy World 2010.
Its loopwing-type wind power generators boast a one-of-a-kind loop-shaped wing structure that allows generating electricity from winds that have speed as low as 2m/s.
In addition, the design also makes it possible for the device to produce power without much noise.
One of the models of loopwing type wind power generator is called the TRONC. It features a hybrid solar and wind energy generator and it doesn't need extra source of energy. Besides, the streetlight can be even connected to such external devices as LED display systems, informs Aving.
TRONC represents a complex that includes a small windmill and sunlight panel mounted on top. It also features a loop wing style blade of that is 1.5 meters in diameter.
