IBM Solar Collector Harnesses the Power of 2,000 Suns | Inhabitat - Sustainable Design Innovation, Eco Architecture, Green Building

A team of IBM researchers is working on a solar concentrating dish that will be able to collect 80% of incoming sunlight and convert it to useful energy. The High Concentration Photovoltaic Thermal system will be able to concentrate the power of 2,000 suns while delivering fresh water and cool air wherever it is built. As an added bonus, IBM states that the system would be just one third the cost third of current comparable technologies.

 Based on information by Greenpeace International and the European Electricity Association, IBM claims that it would require only two percent of the Sahara’s total area to supply the world’s energy needs. The HCPVT system is designed around a huge parabolic dish covered in mirror facets. The dish is supported and controlled by a tracking system that moves along with the sun. Sun rays reflect off of the mirror into receivers containing triple junction photovoltaic chips, each able to convert 200-250 watts over eight hours. Combined hundred of the chips provide 25 kilowatts of electricity.

The entire dish is cooled with liquids that are 10 times more effective than passive air methods, keeping the HCPVT safe to operate at a concentration of 2,000 times on average, and up to 5,000 times the power of the sun. The direct cooling technique is inspired by the branched blood supply system of the human body and has already been used to cool high performance computers like the Aquasar. The system will also be able to create fresh water by passing 90 degree Celsius liquid through a distillation system that vaporizes and desalinates up to 40 liters each day while still generating electricity. It will also be able to amazingly offer air conditioning by a thermal drive absorption chiller that converts heat through silica gel.

Replacing expensive steel and glass with concrete and pressurized foils, the HCPVT is less costly than many other similar installations. Its high tech coolers and molds can be manufactured in Switzerland, and construction provided by individual companies on-site. Through their design, IBM believes they can maintain a cost of less than 10cents per kilowatt hour.

 

 

Heck yeaa! Hs is what we need

Energy harvesting pavement powers its own streetlights.

London-based startup Pavegen has developed tiling that can harvest kinetic energy from people’s footsteps, turning it into up to 8 watts of electricity per footstep.

The tiles are made of 95 percent recycled tyres, and use a proprietary wireless communications technology to transmit data about the number of footfalls and the energy generated via the Internet. A wireless network of the tiles could provide valuable information to city planners and nearby business owners about the number of pedestrians in the area at different times of the day.

At the last Summer Olympics in London, the tiles were installed outside a tube station where they generated enough energy to power lights in the area for five hours a night.

Mysterious Disease Discovered Locally, Strikes Mainly Young Women

It’s a mysterious, newly discovered disease that strikes mainly young women, and it’s often misdiagnosed. Doctors who discovered it, here in Philadelphia, say it’s like your brain is on fire. 3 On Your Side Health Reporter Stephanie Stahl says it starts with personality changes.

Young women dazed, restrained in hospital beds, acting possessed and then becoming catatonic. They’d been so normal, when suddenly their lives went haywire.

“One minute I’d be sobbing, crying hysterically, and the next minute I’d be laughing, said Susannah Cahalan, of New Jersey.

“I was very paranoid and manic. There was something wrong. I thought trucks were following me,” said Emily Gavigan, of Pennsylvania.

And it got worse for Emily Gavigan, who was a sophomore at the University of Scranton. Hospitalized, and out of it, she couldn’t control her arm movements. Then there were seizures, and she needed a ventilator. Her parents were watching their only child slip away.

“It was life and death for weeks,” said Grace Gavigan, Emily’s mom.

“We were losing her. This is something that I couldn’t control,” said Bill Gavigan, Emily’s dad.

Doctors also couldn’t figure out what was wrong with Susannah.

“I had bizarre abnormal movements, would leave my arms out extended, you know, in front of me. I was a relatively normal person, then the next minute I’m hallucinating and insisting that my father had kidnapped me,” said Susannah.

Turns out, Susannah and Emily weren’t mentally ill. They both had an auto immune disease called Anti-NMDA Receptor Encephalitis, when antibodies attack the brain, causing swelling.

Susannah says this is how doctors explained it to her parents, “He told them her brain is on fire. He used those words: ‘Her brain is on fire.’”
