Indoor use only due to limited tolerance for heat and light. No info on the longevity of the cells. No info on the cost of the cells. No details given on the actual power output we can expect.

Not saying this is all bullshit. If they can make most household devices charge from ambient light without significantly increasing the cost or causing other issues, I'm all for it. But as with so many other "world changing" technologies being promoted in tech media, I will remain skeptical until it becomes a real product that can show real results.
