For millions of homeless people around the world, finding shelter from the elements can be a challenge. Extreme winter cold and summer heat can be fatal to people who aren't sufficiently protected. Tough tents called WeatherHYDE, produced by billionBricks a small non-profit in Singapore, are pitched at alleviating the problem. Priced at about $100 per WeatherHyde tent, the triple-layer weatherproof fabric is draped over a basic structure assembled from common PVC pipes. The idea is for people to find or purchase the inexpensive pipes on their own, so the tent fabric and joint parts can be shipped to them more easily, explained Prasoon Kumar, founder and CEO of billionBricks. The next step is to try and install solar panels into the tents, which, in the long-run (6-8 years, possibly), could be used by the families to be sold back into the electric grid.
