Top 10 Solar Technologies to Watch Out For


Solar power technology is moving forward by leaps and bounds, with some new advancements being built out into usable installations virtually every day. Design concepts once thought to be ‘pie in the sky’ ideas are being implemented, and making a simple solar panel array look like old-school technology .While it may be some time before you see some of these solar technologies in use, chances are it will be sooner rather than later, so keep your eyes on these:

Mencairnya Methane Hydrates=Kiamat? - SejutaBlog


Satu lagi berita buruk, Pemanasan Global juga membawa satu potensi bencana besar bagi planet kita, yaitu mencairnya Methane Hydrates: Metana beku yang tersimpan dalam bentuk es. Jumlahnya cukup mencengangkan 3.000 kali dari metana yang saat ini ada di atmosfer.

Making Solar Power at the Office? : CleanTechnica


"New Energy’s solar cells in their transparent SolarWindow™ generate electricity by using the visible light in artificial fluorescent lighting typically installed in offices and commercial buildings."

A Thin-Film Solar Panel Installation : CleanTechnica


Many people envision solar power as rigid silicon panels mounted on a roof. With thin film solar cells, you’re more likely to not see them, or even know they’re there. This article is about a real-life thin film solar project.

Not many bloggers are able to witness the technologies we research and write about. It’s one thing to be able to buy afford a cool “green” gadget (usually not very green), but another to see the many forms of solar, wind, geothermal, etc., which are always changing and developing around the world. So when my employer decided to go solar, you might imagine my excitement.

GreenSun Develops Colorful Solar Panels that don’t need Direct Sunlight : CleanTechnica


Solar power comes in many forms, from rigid to thin film. The panels are shiny, gleaming and ready to harness the power of the sun.

They’re also usually silver. Yet they also come in colors, not just for looks, but for efficiency.
A Jerusalem company called GreenSun has developed bright-colored panels. Officials say the hues capture different parts of sun’s spectrum, and don’t need direct sunlight to work, according to National Geographic News.

The colored collectors are still in development, but the company says its panels will cost less than a buck per watt to manufacture, compared to more than $4 a watt for conventional solar.

The technology is based on concentrating visible and ultraviolet light without concentrating heat, which reduces the performance of conventional cells. GreenSun also says its panels only require 20 percent silicon, with a conversion rate of up to 20 percent, or up to twice as much as commercial panels now on the market.

UW Engineers Invent First Tree-Powered Circuit : CleanTechnica


UW Engineers Invent First Tree-Powered Circuit : CleanTechnica
In a first, researchers at the University of Washington in Seattle have developed a completely tree-powered electrical circuit.

The nano-scale device—approximately 130 nanometers [a nanometer is one billionth of a meter] in size—consumes just 10 billionths of a watt (10 nanowatts).

Unlike the legendary science fair experiment in which a potato-based electric circuit is created using two electrodes (each electrode being a different metal, which react with the starch, causing a potential difference and thus a current), the UW device utilizes electrodes comprised of the same metal, and is able to generate (output) 1.1 volts. “As far as we know, this is the first peer-reviewed paper of someone powering something entirely by sticking electrodes into a tree,” according to paper co-author Babak Parviz, associate professor of electrical engineering at the UW.

Teenager invents £23 solar panel that could be solution to developing world's energy needs..made from human hair | Mail Online
new type of solar panel using human hair could provide the world with cheap, green electricity, believes its teenage inventor.
Milan Karki, 18, who comes from a village in rural Nepal, believes he has found the solution to the developing world's energy needs.
The young inventor says hair is easy to use as a conductor in solar panels and could revolutionise renewable energy.
