Alternative energy sources

Sustainable Satellite Internetwork at the Big Green Gathering
At an environmental festival near Cheddar in Somerset, UK, Psand.net, a consultancy and skills oriented organisation, ran a mobile, sustainably powered satellite wireless internetwork, to investigate the feasibility of alternative sources of power generation.

Connection to the Internet was made using a bi-directional microwave satellite link, while public access terminals were provided at the festival giving visitors a choice of operating systems with which to feel at home and a chance to compare them. Power for the network and laptops for the whole event was provided by solar power and a pedal generator.

Supplying power to remote ICT network sites
When network reach rural and remote areas ahead of the main electricity supply, alternative power sources are necessary. Diesel power generation is common, but technological developments have made it increasingly possible to consider renewable power sources that do not increase net greenhouse gas emissions. These energy technologies are becoming progressively less expensive and more practical.

Solar, wind and water (micro hydro plants) generation is feasible in many places as are   combinations of alternative energy sources (e.g., joint solar and window power generation in Namibia). For individual terminals, human power generation is sometimes used as in pedalling, where a human can generate 20 W or even 40 W fairly easily.

CambodiaSchools.com
Suffering from the legacy of the Khmer Rouge destruction of the education system, some 3,000 villages in Cambodia have no schools, most children either having no chance to learn or studying in the open fields. American Assistance for Cambodia is helping these children in remote regions of Cambodia to catch up with their overseas peers, by providing access to ICTs for education. Through an adopt-a-school programme at CambodiaSchools.com, donations are solicited online to build the schools. Over 200 have been completed so far. With energy provided by solar panels, several of the schools are now connected to the Internet, with future plans to connect the rest.
