It’s a game-changer for them. No walking long distances or paying to recharge mobile phones. Kerosene lamps and their attendant fire hazards have been eliminated. Rural dwellers spend much less now on fuel, and have figured out how to power tiny TVs with the lamps too.
There are probably hundreds of millions of people now who have mobile phones but no electricity in their homes. Plus, of course, solar-powered light at night makes food preparation and life in general way easier.
The lamps cost $30 and can be purchased on installment plans for $2 a month. The company making them just received an order for 1.5 million lamps.
