Photovoltaic Retinal Implants Powered by Onboard Solar Cells
Scientists at Stanford University have developed photovoltaic retinal implants for people that suffer from degradation in their photoreceptor cells, causing partial vision.
Yarga YoYo: Concept Fuel Cell Vehicle Inspired by Dean Kamen's Segway
There are some ideas that could evolve no matter what technology is used to apply them. For example, James Yarger, an industrial designer, thought of a concept vehicle made from recyclable materials, inspired by Dean Kamen's Segway.
Panasonic Plans Ultra-Compact Home Battery System for Solar/Wind
Panasonic Corp, who recently took over more than 50% of Sanyo Electric's shares, has a plan of marketing lithium-ion batteries for home use, and they want to finish that plan around 2011.
Aegir: Scotland's Largest Wave Power Project
Just recently, Scotland-based energy developer Pelamis has signed a joint-venture with the European energy giant Vattenfall, for the huge energy project off Scotland's Shetland Islands. The costs of the project rise to almost $100 million.
New Hope for EVs: Bolivia Holding World's Richest Lithium Field
As the automotive industry has oriented itself towards green energy usage, the need of a "supreme" alternative resource is obvious. And what is more obvious is the demand of Electric Vehicles. EVs need to store their energy in batteries: mainly Lithium-Ion batteries. As of this particular reason, Lithium seems to be one of the most searched resource.
Asia's Largest High-Concentration PV Plant Capable of Producing 100MW in Taiwan
Yesterday ( 23 December 2009) has been inaugurated in southern Taiwan the largest High-Concentration Photovoltaic (HCPV) in Asia. According to the officials this HCPV power plant is expected to save up to 700 tons of carbon emission annually.
Glitter-Sized Photovoltaic Cells Expected to Produce More Power at Less Cost
â€Ã…“Eventually units could be mass-produced and wrapped around unusual shapes for building-integrated solar, tents and maybe even clothing. This would make it possible for hunters, hikers or military personnel in the field to recharge batteries for phones, cameras and other electronic devices as they walk or rest.†said Greg Nielson, Sandia lead investigator.
New Discovery: Generating Electricity With Ground Bacteria Shewanella
Bio-chemist David Richardson of the University of East Anglia in the United Kingdom said that Shewanella is the ideal candidate for environmental-cleanup tasks as it lives in the underground: "Understanding their biochemistry could help to develop strategies to stimulate their activities [at the cleanup sites]."
Solar Tree – An Artificial Tree to Produce Clean Electricity from Wind and Sun
The leaves of the tree are connected to a vertical-axis wind turbine. Every leaf has a grouping of high-efficiency photovoltaic solar cells that transmit electricity down the tree's core. The solar cells are connected from the upper turbine to the trunk through wireless energy transfer by induction.
Hot Electrons Could Increase the Solar Cell's Power Output
Researchers at Boston College have developed new solar cells that successfully use hot electrons to increase the cells' power output. According to the scientists, the concept could lead to solar cells that break conventional efficiency limits.
