THIS IS GENIUS. Why haven't we figured this out before? Whenever I go to Africa and South America I always make sure to pack a ridiculous amount of batteries. People always ask me for them because batteries which you purchase in country are horrible. This blending of an ancient technology with a new technology is a game changer, and as a mechanical engineer, I find it to be super exciting.

For those wondering, the units are just under $10, so the payback for a family in a developing nation should end up being about 3 months. This effectively eliminates the kerosene lighting poverty trap that millions of people fall into. I absolutely love it when engineering innovation solves an economic and environmental issue.
