Iron Pyrite Used for Cheaper Solar Panels
Many of today's solar panels use silicon for transforming solar energy into electrical energy. But this is not only quite expensive, but also can be in shortage.
The study the Lawrence Berkeley National Laboratory has performed and recently published tells us that there are many cheaper and abundant alternatives to silicon. One of them is iron pyrite, a quite common resource.
New BiFeO3 Crystal Can Improve Solar Cells Efficiency & Price
Physicists at Rutgers University discovered a crystal made of bismuth, iron and oxygen(BiFeO3) which can revolution electronics industry and highly improve solar cell efficiency.
How to use solar energy at night or during rainy days
In Granada- Spain, German scientists of Solar Millennium AG, have developed a solar-thermal power plant called Andasol 1. The most interesting thing about this power plant is that it can produce energy even when the sun is not shining: at night, on clouding or even rainy days.
Sugar Cube-Sized Solid Oxide Fuel Cell
The world's smallest solid-oxide fuel cell(SOFC), as small as sugar cube, was recently developed by the National Institute of Advanced Industrial Science and Technology (AIST). The sugar cube-sized SOFC is is operable at 550°C.
Geothermal Energy Source in Paris Will Power up New Residential Area
Paris wants to invest in geothermal energy and already started to dig and drill to reach for underground hot water.
How to Make a $5 Solar Water Heater From Junk Fridge
One simple way of making hot water has been perfected by a blogger on thesietch.org, and it relies on a simple and easy to find piece of junk: an old refrigerator!
Gain Up to 30% More Solar Power With Automatic Cleaning System
Heliotex has released the first pending patent of automatic cleaning systems for business and home solar panels. Heliotex Automatic Solar Panel Cleaning Systems automatically washes and rinses the solar panels as often as you find necessary. The system helps you to maximize your investment by allowing your solar panels to achieve their full potential (dirty solar panels lose up to 30% efficiency).
Wave Treader: Joining Wind and Wave Power
By combining wind and wave power, the energy output can be drastically increased. The Wave Treader that enables the mix-up will probably be available on the market by 2011.
World's Most Efficient Solar Water Heater Made by Surface Power
Surface Power received an independent certification from TUV Rhineland that their solar water heaters are at least 131% more efficient in the morning and evening, and 76% more at midday than other solar heaters.
New Nano-Materials Mix Boosts Li-Ion Battery Capacity
Carbon nanotubes have been in the focus of many scientists and universities studying battery technologies recently. Now, a group of Rice University researchers found out the novel properties of carbon nanotubes surrounded by metal-oxide arrays for use in lithium ion batteries.
