Thanks for the Link to the MSU prototype. I still think you will see MHYR in the market before this invention.
Although MHYR website has been a bit quiet of late.
I did a search and found that on January 25, 2012, Manthey Redmond filed "Opposed Piston Multi-Fire Engine" Provisional Patent Number: 2012900277.
I'm hoping that the MHYR site has been quiet while they waited to get their latest patent filing completed. Maybe Feb will see some action on their website?
