Ken Hall originally designed his Cobb oven as an alternative to the paraffin stoves found in South Africa’s informal settlements. These makeshift stoves are the major cause of deadly settlement fires. The Cobb concept has been very well received and today has been updated and redesigned. The Cobb oven is the small, portable barbeque that lets you fire up the coals anywhere, any time. He was named in Time Magazine in 2001 for his internationally acclaimed table top Cobb oven
He later invented a solar candle which, spurred again by the devastating fires in townships caused by candles or paraffin lamps. The Solar Candle was shortlisted for distribution throughout Africa for its durability and unique performance.
