Portable Solar Power For Portable Hardware?

Tjeerd writes "Because the 'green revolution' is accelerating, I felt it was time to get involved. Last week I started with buying a portable solar energy charger for my mobile phone. But soon I was thinking of also recharging my Asus Eee netbook with a portable solar energy recharger. I found things like the Portable Power Pack, Foldable Solar Chargers, and the Solar Gorilla. The Solar Gorilla looks quite interesting and might be able to recharge my netbook and fits nicely in a rucksack. But I would like some real-life feedback. If you have experience with these or other portable solar devices, what has worked for you?"

335,000 Cellular Base Stations to Include Solar Power by 2013, According to ABI Research

As mobile network expansion moves ostensibly to emerging markets where solar energy levels are more favorable, solar power appears ready to play an important role in reducing the costs of cellular service delivery and ensuring a more reliable power supply. The OEMs’ drive toward reducing base station power consumption, along with improvements in photovoltaic cells, have meant that solar energy is now a very viable solution for powering cellular base stations.

A technical and sentiment look at Evergreen Solar's (ESLR) price action and investor sentiment

As you might deduce from the company's name, Evergreen Solar (ESLR: View sentiment for ESLRsentiment, chart, options) develops, manufactures, and markets solar power products including solar cells and the ever-popular solar panels. Shares of the alternative energy specialist seem quite inexpensive, closing yesterday's session below $3 per share. Many investors are taking advantage of this perceived discount by betting on a return to warmer climates for the equity. But the recent decline in crude oil and energy prices has brought with it a heavy degree of scrutiny for the once blazing hot solar sector, and there are a few indicators that might temper your enthusiasm for this discount-bin stock.

7th-Grader Designs Three Dimensional Solar Cell

Hugh Pickens writes "12-year-old William Yuan's invention of a highly-efficient, three-dimensional nanotube solar cell for visible and ultraviolet light has won him an award and a $25,000 scholarship from the Davidson Institute for Talent Development. 'Current solar cells are flat and can only absorb visible light'" Yuan said. 'I came up with an innovative solar cell that absorbs both visible and UV light. My project focused on finding the optimum solar cell to further increase the light absorption and efficiency and design a nanotube for light-electricity conversion efficiency.' Solar panels with his 3D cells would provide 500 times more light absorption than commercially-available solar cells and nine times more than cutting-edge 3D solar cells.

Solar Power Game-Changer: "Near Perfect" Absorption of Sunlight, From All Angles

Researchers at Rensselaer Polytechnic Institute have discovered and demonstrated a new method for overcoming two major hurdles facing solar energy. By developing a new antireflective coating that boosts the amount of sunlight captured by solar panels and allows those panels to absorb the entire solar spectrum from nearly any angle, the research team has moved academia and industry closer to realizing high-efficiency, cost-effective solar power.

Solar Thermal Power May Make Sun-Powered Grid a Reality

It's solar's new dawn. For five decades solar technologies have delivered more promises than power. Now, new Breakthrough Award–winning innovations are exiting the lab and plugging into the grid—turning sunlight into serious energy.

Solar Energy to Power Up Aircraft

The future of aviation looks bright, aircraft constructors say, in the light of the fact that, next year, a new 1.5 ton aircraft, powered entirely by the sun, will complete a first-of-its-kind test flight. The plane is being built in order to prove that using solar energy to power up airplanes is a sustainable process. To further prove this, the new aircraft will attempt a trip around the world by 2011. If the try succeeds, then most likely the patent will be commercially available shortly after.

Organic dyes bring increased solar power

Particle physicists have long been familiar with the idea of shifting the wavelength of light to make detection easier – now the same idea could prove a boon for solar power. Michael Currie and colleagues from the Massachusetts Institute of Technology have shown that planar waveguides with a thin film of organic coating on one side and solar cells on the edges can produce significantly more power than the solar cells on their own.

Sun Presenter Console extension is useful but undocumented

Currently in late beta, the Sun Presenter Console (SPC) is Sun Microsystems' latest extension for OpenOffice.org and StarOffice. Other extensions from Sun in the last year, such as the Sun PDF Import Extension, Sun Presentation Minimizer, and Sun Weblog Publisher, have sometimes been lacking in design and sometimes buggy, but all of them are so invaluable that you might wonder why they are extensions instead of new features. SPC is no exception. It gives slide show presenters a separate view of their presentation and some tools to help them organize and deliver their talks, but includes no indication of how to set it up or use it.

Energy Star Setting Consumption Guidelines For Game Consoles

It's no secret that your game console is not going to do much to save you money on your next power bill. However, Energy Star is finally prepared to set guidelines on energy consumption for these devices. In order earn an Energy Star seal of approval, manufacturers will have to use less than one watt during 'off' mode, and less than 5 watts in standby. The devices must also automatically power down after sitting idle for an hour. Furthermore, any set-top box and DVD/Blu Ray/Movie playback functions have to come within 10% of current Energy Star requirements.

Energy Saving for Star Automation Robots

In today’s market, where costs are constantly increasing, reducing the total cost of the finished product is vital in order to cut energy consumption. A recent study on energy saving, which was based on the consumption of the Star Automation robots, showed that by using two functions available in the Star robots it is possible to reduce the energy needed. The “SERVO SLEEP” function, which shorts the power to the servo motors, is activated when the robot is not being used or it is working in auto mode. In both cases Star measured the power consumption of the robot and compared the resulting energy values. With the servo sleep function OFF and ON respectively at a set time of 1.0 seconds, the results are a saving of 8.53% when using the Auto Mode and of 44.

Tiny solar cells built to power microscopic machines: New technology described in inaugural issue of Journal of Renewable and Sustainable Energy

Some of the tiniest solar cells ever built have been successfully tested as a power source for even tinier microscopic machines. An article in the inaugural issue of the Journal of Renewable and Sustainable Energy (JRSE), published by the American Institute of Physics (AIP), describes an inch-long array of 20 of these cells -- each one about a quarter the size of a lowercase "o" in a standard 12-point font.

10 IT Power-Saving Myths Debunked

New Eye on the Outer Solar System Launches Successfully

There's a new spacecraft in Earth orbit, with a really "far out" mission: to map the outer solar system. NASA's Interstellar Boundary Explorer mission, or IBEX launched successfully from the Kwajalein Atoll in the Pacific Ocean at 1:47 p.m. EDT, Sunday, from an Orbital Sciences Pegasus XL launch vehicle. IBEX will be the first spacecraft to image and map dynamic interactions taking place in the outer solar system. The two Voyager probes sent back a limited amount of information about the region of space where our solar system ends and interstellar space begins. But beyond that, not much is known about this area. The region is about three times further from the sun than the orbit of planet Pluto. "No one has seen an image of the interaction at the edge of our solar system where the solar wind collides with interstellar space," said IBEX Pr
