Hukum Henry (Fisika)

Step 2010, green technology is applied though apparently intensified industry. This can be seen at the Consumer Electronics Show in Las Vegas, 7-10 January. In the largest international electronics exhibition, many device exhibited green technology with new innovations. Consumer Electronics Association, organizer, and even opened a special exhibition space for "green technology". Here are some devices "green" is on display there.

Regen Solar Charger
Regen released Renu solar recharging system designed for the home. Each charger is equipped six-watt solar panel and can be integrated into the battery with the USB plug. Charger is also integrated with a terminal for the speaker, an LED desk lamp, and re-charger for iPod.

Hukum Faraday

Rubbish indeed proved to be converted into energy sources. Whether it's as biomass or with landfield powerplant technology that uses waste as fuel to heat water and drive turbines.

If using biomass, the efficiency is still low, because the energy produced is not proportional to the energy required. Technology landfield powerplant or garbage-fueled power plants, considered to be more efficient, because all the garbage that is used as fuel and energy it generates is also greater. It's just a question arises, how is the smoke and pollution resulting from burning them?

The technology is now considered to be more efficient is to use plasma gasification. Although this technology has found more than 40 years ago by NASA, the United States space agency, to regulate the temperature in the spacecraft, but applications for waste-fueled power plants still not much in the world, only a few countries, namely Japan and the U.S. use States.

Always Caring PC

Like a machine, your computer needs to be treated regularly. Although the new computers do not need too much handling, when the PC is increasingly being used and installed many programs, all kinds of trouble began to appear and quite cumbersome.

Problems often encountered is the stacked temporary files, which seriously hamper the speed and performance PCs. These unwanted files will take up quite a lot of space on your hard drive. If you try to get rid of unwanted files, but did not follow procedures bendar, you will see the fact that the actual file is not missing and the PC hard drive is still dirty and chaotic. Such actions will make a new file storage is slower and less reliable.

If your windows xp user, this OS can answer this challenge by providing a way of maintenance and care are beneficial. This can be found in System Tools.

Third Parties Utilities
If you are a user of Windows xp, maybe you can use tools to perform system maintenance and PC maintenance. But if you are not satisfied with the performance of system tools, there are many programs available to assist and care for your computer, and keeping the equipment running smoothly.

Best Pure Water, Where?

University of South Florida researchers found the best pure water on the prickly pear cactus. Inhabitants of this desert is very effective in transporting sediment and bacteria from dirty water and the good news of this plant can live in the world.

This is not the first research found that the ability of cactus plants. Mexican community in the 19th century using a cactus as a device for purifying water. Thick layer of resin on the cactus that save water, is a part which is responsible for purifying water.

Researchers then extract the sap and added into the dirty water because of sediment and bacteria.

Sediment and bacteria cause the sap to join, then settles on the bottom and separates 98% of bacteria in the water.

Researchers looked at communities in developing countries using a cactus in their daily lives. They used to boil the sap of a cactus to get the sap is then added to the water, just as did the investigators.

But there are still hurdles to be overcome. Resources need to be prepared to develop the spread of cactus and how to convince the public that the water is filtered completely free of bacteria.

If some of these problems can be solved, it is cheap and clean water that can reach millions of people who lack these resources.
