For a long time I have ben following the development of a camp stove, by biolite.
This is a wonderful stove, it is powered by pinecones, and has a steak cooking attachment which directs the heat of the flames, (which are intensified with a fan) under the steak, thus cooking and smoking it at the same time.
Another bonus is that it converts some of the heat energy to electricity to charge any USB powered device, as quickly as mains power.
Here it is in action, on an evening, when I was not booked to do any talks to garden clubs.
Well, here it is assembled and ready to light.
The pine cones are burning brightly
Now we are talking – flame grilled!
Maybe just one more pine cone will finish it off?
