In many disaster scenarios electricity is a badly needed resource that can be very hard to come by. Power lines are knocked down and generators can be in short supply. A logical (and obvious) solution to this is to use sustainable grid-free electricity generation. One company has done this by making the solar tent.
The idea of using renewable energy sources in such conditions could be viable options for rescue work and to satisfy the energy needs. Unconventional power sources are available at a minimum cost and certainly very safely. Both wind power and solar power will become more portable energy sources used in the future.
One of the solutions which use solar power is PowerMod. It is a portable solar tent, ready to help in relief work the victims of disasters. PowerMod is a simply kind of shelter with a 20 x 20 foot roof of flexible solar panel made by Ascent Solarâ€™s thin film solar cells. Being assembled in only 15 minutes by two persons it has a weight of 165 pounds totally and gives a power output of 4.5 KWh/day.
