- Intermernet 7y agoNot really, as it didn't use any energy not present in the 9v battery. This is about using solar energy in a more efficient arrangement, through reflection of waste solar energy to heat a medium and create a higher efficiency thermo-voltaic cell based on a photo-voltaic cell (I'm probably very wrong with my terminology in the last sentence, but, either way, it ain't no burning graphite connected to a battery.)
