Be sure and schedule your open heart surgery only on a sunny day... no clouds permitted... Heaven help you if a bird lands on the collector...

This strikes me as inappropriate technology. Laser scalpels are already available and are not weather dependent.

Laser scalpels are already available and are not weather dependent.

I imagine it is very expensive to operate a laser scalpel (I'm not a doctor). Perhaps they could make a laser scalpel using this technology cheap enough so that it could be used instead of the old-fashioned scalpel. It could be used for relatively minor surgery -- if this helps the patient to bleed less -- even in minor surgery, that is a big advantage, yes? This could also be used in field hospitals and poor countries where the electricity supply is not dependable or conventional lasers are too expensive. I hope this will develop into affordable technology that will help many people.
