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.

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.

Waste to Energy - Generating electricity from garbage and pollution


The consumption habits of modern consumer lifesyles are causing a huge worldwide waste problem. Having overfilled local landfill capacities, many first world nations are now exporting their refuse to third world countries. This is having a devastating impact on ecosystems and cultures throughout the world. Some alternative energy companies are developing new ways to recycle waste by generating electricity from landfill waste and pollution. The articles on this page explore waste to energy technology and potential.

A Step Closer to Solar Power in Space


Mitsubishi Electric Corporation and IHI Corporation are undertaking an ambitious project of $ 21bn. They are aspiring to design and develop a Space-based solar farm that would generate 1GW of power. This will require an area of four square kilometer consisting of rows of solar panels. This space solar farm will be housed 36,000km above the surface of the earth

Car the future will run on its own waste energy

Electricity is the ultimate portable fuel, so running a car on electricity opens a world of possibilities in terms of harvesting and using sustainable energy while on the go. Thermoelectric innovator Amerigon Incorporated has one especially interesting approach: capture the waste energy from the car’s engine exhaust and recycle it into electric power. Through its BSST subsidiary and with $1.1 million in backing from the U.S Department of Energy, Amerigon is entering the fifth phase of the project. Completion is targeted for March 31, 2010, and then look out, world.

Amerigon, BSST and Thermoelectric Energy

Amerigon’s BSST subsidiary has already applied thermoelectric recovery principles to heating and cooling systems. It’s a logical choice for the project, having developed the highest-efficiency thermoelectric technology achieved so far. The program kicked off in 2005 with a team including Visteon Corporation, BMW, UC Santa Cruz, the National Renewable Energy Laboratory, and the California Institute of Technology’s Jet propulsion Laboratory. Ford joined the project after analysis and concept phases established a fuel savings of up to 12% in simulations, and the thermoelectric system was bench-tested in the lab using hot gas instead of actual exhaust. Phase 4, which is drawing to a close, involves testing the system on a BMW six-cylinder engine.

Cars as Energy Harvesters, and Energy Generators

The new technology promises a sea change in the way we conceive of cars as energy users - and producers. For example, an electric car that harvests solar energy could also incorporate BSST’s thermoelectric system, while generating kinetic energy as it passes over a roadway - and using available wind as an additional power source. In the not too distant future, cars that run only on fossil fuels will be just that - fossils.
