AIE has nice work and ties back to the Norton motorcycle and their Wankel type engine bike.

Now for reality. If they had something of a threat nature to Coates I would probably be on it long ago. It is a good idea but a big NOPE for me.

I am a major 'founding' investor in this company, over 15 years.
Duryea Technologies is still not a public company. I will be sure to let you know when it happens.

They have modified the Wankel extensively as described here.....

This is not competition to Coates. Therefore I am invested in both.
Their electric motor/generators would be superb for small to medium Coates engine-generators.

Together, these two would mop up the entire market. Period.
Time will tell.
