A Stylish Solar Charger for Your Gadgets

charger

A few years ago, the company Rawlemon designed a spherical lens solar generator, which works better to capture solar energy than a regular solar panel array, and looks much better. The original Rawlemon spherical lens solar generator was created by a Barcelona designer and architect André Broessel of Beta Torics. The system basically uses a large glass ball that is filled with water to concentrate the sun’s energy onto a PV panel. In this way the suns energy is concentrated by up to 10,000 times. The ball can also be rotated and includes a tracking system, meaning that energy collection is maximized throughout the day. However, the design has some serious drawbacks, such as weight of the water-filled ball, which can’t really be supported by most roofs. Another drawback is the problem of producing the glass balls of sufficient quality and size.

Solar Bridge in London Completed and Operational

Solar photovoltaic (PV) panels on new Blackfriars bridge

Blackfriar’s Bridge, which is the largest solar bridge in the world and part of London’s Blackfriar’s railway station, is finally finished. Work on the structure started in 2009 as part of the worldwide energy conservation efforts. The bridge crosses the river Thames and the solar panels that now cover it were installed by the firm Solarcentury.

A New Type of Washing Machine Cuts Water Use by 70%

pt.5.5008figure2

One of the biggest drains on freshwater resources is the household washing machine. As reported by the EPA, a washing machine uses about 41 gallons of water per load on average, while a typical US family uses the washing machine once per day. The UK-based company Xeros has come up with a washing technology that uses 70% less water per washing cycle. This technology also uses a special “bead cleaning” method that is environmentally friendly and apparently cleans dirty clothes even better than regular soap.

A Glow In The Dark Plant to Replace Lights?

The company Bioglow has successfully developed a plant that produces light in a completely natural process that requires no chemicals or electricity. These kinds of glowing plants were invented by molecular biologist, Dr. Alex Krichevsky and they are the result of his research into bioluminescent marine bacteria and the molecular biology of plants. Bioglow’s Starlight Avatar, as it is called, is the first light producing plant in the world, and it could become a sustainable replacement for traditional, electric lighting.

Plastic Bags Can be Recycled Into Diesel Fuel

title

Researchers at the University of Illinois, or more precisely the Illinois Sustainable Technology Center, have discovered a process that can turn used plastic shopping bags into a compatible drop-in diesel fuel and a number of petroleum products. The recycling process also works to recover most of the initial manufacturing inputs that go into producing plastic shopping bags. Given that each year an estimated 100 billion shopping bags are thrown away in the US alone, this is great news indeed.
