Energy positive rollercoaters?

I had a thought, is it possible for rollercoasters to charge up energy when its not using power? If it uses power moving upward then couldnt it collect kinetic energy to store when it goes down? It could be a possibilty just food for thought... By Dagwood Perry

ANOTHER New Hydrogen Car: Chevrolet Sequel

Now, GM is developing a new hydrogen fuel celled car, like many others are. What makes it special though is that in spite of the fact that they are HHO powered, they still drive like a normal gas engine car, making it be a better experience. General Motors has been working on hydrogen powered cars for a full decade,, but with the last push, they have designed a new clean slate 21st century car that didn't depend pn the old technologies. These hydrogen cars make no emissions, but they do take a lot of emissions to create the actual hydrogen. Although this is still a problem, the blame is switched from the car companies to the manufacturers creating the hydrogen.

British Petroleum

British Petroleum is a British global energy company that is the third global energy company and the fourth largest company in the world. BP is a multinational oil company that is the UK's largest company. The company is alternative energy, oil exploration, natural gas, and petroleum.



BP has been around since the early 20th century. As you may have heard there is a great disaster in the Gulf of Mexico. There is a oil spill that pours more than 200,000 gallons per day. Eleven people died in the explosion of the oil.

Shoe Power Generator

By Deputy Johnson

Dr. Ville Kaajakari, assistant professor of electrical engineering at Lousisana Tech University has developed a technology that harvests power from a small generator embedded in the sole of a shoe. The shoe efficiently converts a piezoelectric charge used to charge useable batteries or directly power electronics. They could be used to power portable devices without the use of wasteful batteries. The breakthrough uses low cost polymer transducers that has metalized surfaces for electrical contact. Unlike conventional ceramic transducers the polymer based generator is soft and robust matching properties of regular shoe fillings. Therefore the transducer can replace the heel shock absorber with no loss in user experience. The new shoe will be on sale in 1-2 years for about 11$ per heel insert.

Burj Khalifa

by Tito the Flying Asian

Dubai, city known for its engineering marvels, has recently unveiled a new masterpiece: the Burj Khalifa. The Burj Khalifa is the tallest man-made structure ever with a total height of 2,727 feet. The cost for this building was 1.5 billion US dollars, not particularly helpful for Dubais large debt. The building is based on a symetrical Y-shape and has 27 terraces. The building uses 250,000 gallons of water and, during hot weather, 22,000,000 pounds of melting ice to cool it.

Dry Cell Kits

There is a company that can be found online that is making a new way to turn your regular gas vehicle into an efficient hydogen car. These kits can be found for 4, 6, 8, and 10 cylinder vehicles, ranging from small sedand to pick-up trucks. This company, found at http://www.dry-cells.com/, provides high quality HHO ( Hydrogen, Hydrogen, Oxygen) systems. The 8 and 10 cylinder units cost $639.00 dollars with a shipping weight of 15 pounds. The 4 and 6 cylinder units cost $499.00 and has a shipping weight of 11 pounds. According to this site, everything you will need to install the hydrogen system into your car. After this installation, you will be able to save your gas mileage and your emissions, both of which are major things in this world at the present.

Biodegradable Plastic

by Hezikia

Remember the article about the great ocean garbage patch? I have some good news for you if you were concerned. There is a new form of plastic that is biodegradable. The plastics that are normally used are petrolium based but this new plastic is manufactured from biomaterial.

But it is not that easy. For instance you cannot just bury it in any landfill. You must put it in compost areas or they will not decompose properly.

Secondly, they release a small amount of Co2 when they biodegrade, I guess that this is a small price to pay for all the good that it will bring .

The Sun Chip bags and the new PaperMate pens have this ability along with some plastic dinnerware.
