Cliff Allen with his invention of a solar-powered barbecue.  The lens is a Fresnel lens which at the focus can create temperatures of 1500 deg.C from the sun's rays.

 

 

 

 

 

 

Ronald Elliott and Cliff Allen hosted a barbecue and demonstrated that charcoal is not needed to burn the sausages.  This prototype is a little bit big to carry down to the beach!
