Vimana lights TM c Ross Kelly September 2016.
The burning wick is floating on Rapeseed oil fuel, they also burn Olive oil Coconut oil and Hemp oil.
The registered letter contains one of the Vimanalight disks.
They have more than one use.
My kitchen table at the end of a typical day's experimentation!
