BBC reported that Mosers idea is expected to help light one million homes by next year.
It is to me and the million poor whom his idea will help illuminate the homes of. There are really, really poor people in this world. Sounds like something that they can do for themselves. Might even save a few million KWHs daily in electrical usage as well, for those who do have electricity.
I can provide you with FREE lighting that doesn't require water or a plastic bottle. Are you interested? Do you think poor folks might be interested? OK, here's how you do it: go outside during the day.
Bam! Free lighting!
