The dummy load my group (Greater Cincinnati Builders Group) built used mineral oil, which is non-toxic. We tested the DL with a 200W signal for 5 minutes without failure of any components, although the mineral oil could probably do French fries. A construction article on the DL has been accepted by QST, but no projection on the date of publication yet. This shows the top of the DL. The cost is under $20.
