I just love these things that people make at home. Heaters, ovens igloos and what not! It just means that we who pretend to know more really don’t rack our brains enough to come up with things that could just begin to change the world and that too in our own backyards. I mean look at this, a man in a village in china invented a solar powered water heater made of beer bottles. This heater provides enough water for the three family members, so that they can bathe conveniently everyday. It features 66 beer bottles that have been attached to a board. The bottles have been connected to each other, so that the water flows through them. Sunlight then heats the water, as it passes through the bottle, before flowing into the bathroom as hot water.
