[Stoves] radient heat capture, total heat measurement

[Crispin Pemberton-Pigott]

Dear Friends

 

> Ticks can also sence the body warmth of warm blooded animals.  

>Presumably there was no evolutionary advantage in having an organ that
can sense infra red in the same way eyes interpret light but many
animals do have increased sense of warmth, snakes can hunt by it.

I have not heard of an eye that can see IR but birds can see magnetic fields
- something we low-fliers cannot. 

Regards

Crispin
