Solar Gadgets

There has been quite a crop of solar powered gadgets and equipment in the news lately and here is the best to the silliest.

To my mind the best of these is the solar powered air conditioning unit cover by Ecofriend ( Its a great idea that will be best suited to certain areas of the planet, but it is certainly a start!

Excerpt: “The systems will carry PV and solar thermal technology to harvest sunlight and waste heat to cool down the interiors. While conventional solar cells convert 23% light energy into electricity, this new system will boast an efficiency of over 75%. Measuring 3m X 1.3m, the system will carry mirrors, receivers, a concentrator and silicon-based solar cells. The solar cells used in the AC will use 95% less silicon than a conventional solar panel with the same power rating.

Also pretty amazing is the story of the solar powered car that has broken the distance record and traveled over 12,000 miles. The story is via Treehugger (

Excerpt: “The Power of One journey symbolically began 12 June 2008 in Toronto, Ontario, Canada at Seneca College—one of the project’s greatest supporters. The actual drive began in Buffalo, NY. The original plan was to drive the solar car from Buffalo, NY to Inuvik, NT and back to Buffalo, NY. However, according to the project website, communities in Alaska and Washington invited the solar car to visit them and so it did.

In its journey to Los Angeles, it crossed the continental divide 8 times, traveled more than 1,200 miles on gravel roads, took on snow, ice, and the low angle of the Northern hemisphere during the wettest summer of the past 30 years.

Next we have a review and comparison of solar charging flashlights via Treehugger ( Good useful information!

It is certainly a good week for reviews as Treehugger also looked at solar charging or crank charging radios (

Lastly we have a just silly solar power adaptation with the landing peg of a birdhouse being lit up. I would think that the birds living might complain! The story and images are on Inhabitat (

As always I thank you for your time and interest. Please take the time to Digg, Stumble Upon or add to the other social network of your choice to help me spread the word about these issues. Please forward any questions or suggestions to:
