Electronic Waste Shipped Overseas

We've got big problems with disposal of electronic waste. Francesca Lyman shines some light on the issue in her article in Popular Mechanics, republished on Solaripedia with a few additional links and videos. 
Consider this:
- There are 500 million obsolete computers in the U.S. alone.
- 130 million cell phones are disposed of annually.
- 20 - 24 million TV’s and computers are stored annually in homes and offices.
- Only 10% of unwanted and obsolete computers are recycled.
The Silicon Valley Toxics Coalition points out that one computer monitor can contain four to eight pounds of lead, which if released can hurt an entire community. The problem has reached crisis proportions because of the sheer volume of global electronic waste.

Tethered Sails Power Cargo Ships with Wind


It’s an idea that has been tested: a giant sail is attached to a heavy cargo ship, or smaller boat, to capture wind power, thereby reducing fossil fuel consumption, costs and pollution. One company, SkySails, reports that its kite sail will help reduce annual fuel costs by ten to 35 percent, with fewer harmful carbon emissions. The large towing kite resembles a paraglider and is shaped like an aircraft wing to enable it to take advantage of different wind directions. It operates at 100-300m above surface level - much higher than a normal sailing craft - where winds are stronger and more stable. The kite can be used in winds of 12-74km/h (7-40 knots) and not just when the wind is blowing directly from behind the ship. At SOLARIPEDIA.com, we look at two different kite systems from two companies, SkySails and KiteShip. Read more and see pix
