It doesn't use batteries - check out the website. It filters the sunlight through a mask which allows through light for that particular time of day, as far as I can tell, which would be a pretty cool engineering trick. Only works in one geographic place though and would have to be aligned properly.
A neat solution to a problem I never knew I had.
