The Bottled Water Industry: Selling Tap Water 2000 Times More Expensive

A team of researchers from the Lawrence Berkeley National Laboratory and the University of California, Berkeley, has discovered a catalyst metal 70 times cheaper than platinum for use in electrolysis systems, to generate hydrogen from water.

More and more research studies show the fact that biofuels, ethanol, and other zero-carbon burning fuels do more damage than they do good in the long run. According to a recent study, it looks like ethanol, the petrol companies’ saving field, consumes up to three times more water than it was previously thought, as MIT’s Technology Review states.

Using cheaper materials and latest technology scientists have managed to create a new type of concentrating array, three times cheaper and four times more efficient than any other solar cells. Researchers at the Royal Melbourne Institute of Technology have explained why this technology is so efficient by listing some key components and explaining how they work.

A company called Renew Blue, Inc. will use wave power to run a desalination plant in Freeport, Texas. The resulted water will be finally put into corn-based biodegradable plastic bottles. The SEADOG power system is made from a buoy which puts in motion a piston mechanism that rotates a water wheel to generate electricity.

While giant auto manufacturers spend millions to build electric vehicles, a Japanese family decided to open a family-run business in their garage-workshop and to build eco-friendly electric cars by hand.
