SOL is a unique solar-powered laptop with ingeniously integrated solar panels which enable it to function for 8 – 10 hours after 2 hours charging.

The solar panels can also be removed from the laptop and placed in the sun so that they still recharge your laptop while you work with it inside the house.

It is perfect for people who travel in areas where power supply is unavailable or who want to conserve energy.

The SOL runs presently on Ubuntu but other operating systems could be used. It is powered by an Intel Atom D2500 1.86 GHz Duo Core processor with an Intel 945GSE chipset and an integrated Intel GMA3600 graphics card.

It has a 13.3 in LCD HD screen, 320 GB of HDD storage and 2 – 4 GB of DDRIII SDRAM, a 3 MP webcam and  Wi-Fi and 3G/4G/LTE, plus connections for GPS and Bluetooth.

The SOL comes loaded with all the productivity and creativity software you need. Since it runs on Ubuntu, there are thousands of apps. you can download for free.

And with a rugged design built for durability, the SOL will probably last for a long time under all kinds of hardship. There is no information about its weight.

And the cost is only $350. For a waterproof one, add $50 more.

The SOL laptop is produced by WeWi Telecommunications in Waterloo, Canada.

Cheap Non Silicon Solar Cells

We may be on the verge of developing a new organic dye molecule, which could make solar power more affordable.

Dye-sensitized solar cells are cheaper to make than conventional silicon solar cells and can easily be printed on flexible surfaces. However the dyes require the precious metal ruthenium and volatile electrolytes.

Chemistry professor Peng Wang and his colleagues at the Chinese Academy of Sciences have replaced both of them with organic dyes and ionic liquid.

Organic dyes are more abundant and cheaper to manufacture. The ionic liquid, contrary to electrolytes, does not evaporate or leak out at high temperatures, which makes it more convenient to be used in flexible solar cells.

“We demonstrated for the first time that an all-organic dye can be employed to make stable, solvent-free cells exhibiting a high efficiency comparable to ruthenium dyes,” Wang says.

To compete with conventional solar cells, dye-sensitized ones need to be at least 10 percent efficient at converting light into electricity.

Wang and his colleagues achieved 9.8 percent efficiency with the new organic dyes.

Michael Grätzel, a chemistry professor at the École Polytechnique Fédérale de Lausanne, in Switzerland, who invented dye-sensitized solar cells says that it’s exciting to see researchers “getting so close to 10 percent with organic dyes, which is a magic number.”

This conversion may be lower than for commercially available silicon-based solar cells, at 20-25 per cent efficiency but dye-sensitised solar cells are still desirable as they are more robust and intrinsically more stable than silicon-based solar cells.

Samsung Solar ‘Blue Earth Dream’ Mobile Phone

Samsung launched its solar-powered touch screen phone, made from recycled plastic water bottles, which is charged with a solar panel on the back.

This apparently provides enough electricity to make a call ‘anytime, anywhere’.

‘The Blue Earth Dream’ demonstrates our small but meaningful commitments for the future and our environment,’ Samsung mobile chief Mr JK Shin said.

It had been designed to symbolize a flat and well rounded shiny pebble.

The phone has an ‘eco walk’ function that counts the user’s steps with an in-built pedometer.

It calculates how much CO2 emissions have been reduced and how many trees have been saved by walking rather than driving.

The screen brightness, backlight duration and Bluetooth can be set to an energy-efficient mode with one click.

The phone is free from harmful substances such as Brominated Flame Retardants, Beryllium and Phthalate.

Considering that most people keep their phone in their pocket or purse, it is not clear how the phone will be able to recharge itself.
