People's ingenuity never ceases to amaze me.

Nothing new about it.This type of engine was described in Knight's Mechanical Dictionary in 1877,although powered by steam the principle was the same.

Never,ever accustom yourself to be deluded by claims of originality,chances are it's been thought of before.

I saw the piston arrangement in something called "Massive Yet Tiny." That used a different means to synchronize the pistons.

I wonder what part of that Rotoblock is patented.

It appears to be basically a two cycle. I imagine along with that comes the difficulty with emissions and economy.

Very ingenious though.
