Light: Put bleach 50% and water 50% in a plastic bottle and start helping poor community by fixing it on roof. Simple powerful light giving innovation.
Why did our ancestors used to study under candle light?? Think again! I think they never thought about using Bleach
How about Pepsi Co, corporate "Spring Out Of Poverty" co-sponsor of Isang Litrong Liwanag, just donate all the bottles themselves, especially since they bought out and wholly own their bottling facilities as of 2010, raising their quarterly revenues to 14.8 BILLION dollars!
