I found this just a while ago... http://amasci.com/freenrg/magputt.txt The whole idea is to take a magnetron froma microwave oven and install it in a combustion engine. The problem is this guy says it is to be used as a steam turbine, not a combustion engine (and that it is the most effecient steam turbine ever!). He does not state which magnetron to use. Further he gives no math to his claims or any of his 'research'. And lastly the instructions are rudimentary, he does not even explain how to uninstall a magnetron and install it, just where to install it. There are many other occuring errors. This here really debunks the idea: Anything further to add?
