Knut Karlsen`s Self-Rechargeable Solar Batteries
I have always liked the idea of rechargeable batteries, because they only cost a fraction of what they're worth as normal batteries, but now I see a different innovation that I had never thought of, even it was obvious: putting solar cells onto the rechargeable battery, and having it charged for free, and most importantly, anywhere!
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.
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).
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.
Butterfly Wings Have Solar Cells Inside: Inspiration for Scientists
The researchers studied the butterfly wings, using them as molds or templates. They made copies of the butterflies' solar collectors, and transferred the light-harvesting structures to classic Grätzel (or dye-sensitized) cells.
Jim Duke`s Free Electric Car Solar Charging Station
A great man on a great mission: Jim Duke, a known environmentalist of the tiny Aspen community El Jebel , Colorado, gives free of charge electricity to electric car owners.
Stephen White's Solar Powered Air Conditioning System
During those hot summer days when you don't know what to do anymore (suppose you don't use the air conditioner), you're all sweat and packed with ice, didn't it ever come to your mind to use the outside heat, which is essentially energy, to cool down the room you're in?
