Green Wifi

green wifi logoGreen Wifi is a non-profit organization that wants to bring free wifi access to the internet using solar power. They are using off the shelf products installed with linux to keep costs as low as possible. The reasoning behind providing internet access is that development require easy access to information, and what better way to disseminate mass amounts of information than the internet?

This is the essential question though:
Why Green WiFi? A number of non profit entities focus on addressing the digital divide by providing internet access to developing areas. Green WiFi addresses one of the biggest barriers to success: the lack of reliable electricity in developing areas required to power the network.”

Solar Powered Trash

trash binBoston has got some new trash receptacles on their sidewalks that are solar powered trash compactors. It means that more trash can fit in a box without costing the city, the city might even be able to save money because the bins don’t need to be collected as much. This is a yet one more neat use of solar power.

“Developed by a Jamaica Plain inventor, they are powered by photoelectric panels, which supply power to motor-driven compactors inside. Workers extract neat, 40-pound trash bricks instead of trying to manhandle the messy contents of an overflowing can.”

Boston is not the first city to use this technology though. There are bins located in Vancouver; Cincinnati; Queens, N.Y.; Needham; Newton; and Worcester. What city is next?

A novel use of the sun, however, they still need some work as “some people downtown mistook them for mail drops or traffic-light switch boxes.”

Soaring Solar

Solar boat It seems that every year solar power efficiency improves and that this increased energy production allows for more and more uses. People also figure out other ways to use the sun’s heat. And what’s technological innovation without a competition? Well, we all know there are solar-powered competitions around the world like the classic World Solar Challenge that travels across Australia.

Did you know that there are solar powered boat competitions? I didn’t. The Frisian Nuon Solar Challenge is all about raising boats that gather power from the sun’s rays. Recently, Technical University of Delft won the competition.

Tempted to get your own solar boat, check out all of these crazy looking solar boats.

Zepplins for Communication

Large airships, like a Zeppelin, will be floating overhead and beaming cell phone calls to planet’s surface if a Swiss inventor has his way. The airship will use a new way to broadcast that produces less radiation, which is nice considering the ongoing debate about the dangers of cellphones.

Additionally, the airships will be solar powered and be robot controlled, which means that the cost will be low and nice on the environment.

“Thanks to a GPS steering system developed by the Swiss Federal Institute of Technology, the 60-meter long helium-filled balloon will remain stationary at 21 kilometres above the earth.

A small-unmanned aircraft outfitted with a mobile phone antenna and other devices for transmitting digital data will be attached to the zeppelin. The X station has been equipped with giant propellers to help counter the almost constant buffeting from the wind. “

Renewable Energy Gaining Capital

The renewable energy sector is attracting a lot of investment recently, which is great to hear. This is good news because the forces of capitalism are working in favour of our environment. Here’s some great examples of all this renewed interest in renewable energy.

Great new technological development in solar power:

“CA-based Nanosolar had raised $100 million to finance a new solar-cell factory based on an inexpensive process, similar to that used to print newspapers, and that it will make enough cells to produce 430 megawatts of power annually, is just one sign that new types of solar power are emerging as a viable alternative energy source.”

Wind power is generating interest:

“The report says wind power is the world’s fastest-growing energy source with an average annual growth rate of 29 percent over the last ten years. In contrast, over the same time period, coal use has grown by 2.5 percent per year, nuclear power by 1.8 percent, natural gas by 2.5 percent, and oil by 1.7 percent. ”

There is more evidence that switching from non-renwable energy to renewable energy will help create jobs:

2006 is looking to be a great year for improved energy technologies.
