...simple teknologi,inspired by some students from the Massachusetts Institute of Technology (MIT), dikenali sebagai 'solar light bulb", guna peluntur+air+klorin ... botol ini akan bertindak menyerakkan cahaya matahari ,the bleach and chlorine prevent mold and other bacteria from growing in the water, making sure that the "bulb" remains clear and its light bright for up to 5years. The light produced by the solar bottle bulb is equivalent to a 55-watt electric bulb — making it a great way to illuminate a small home, minus the electric costs.:D

for info:
Maximum solar flux on Earth is about 1 kw/m^2, and there are about 1500 square inches per square meter.So the rule of thumb would be .67 watts per square inch of bottle cross section facing the sun on a sunny mid-day. Last edited by dauswq on 30-3-2013 01:42 AM
