Perhaps ... I'll wait and see to see how it pans out over time ... it is still a bit early I think to call it one way or the other.
Remember ... this HH is not really in competition against other non-hybrids ... it is in competition against other types of hybrids ... including PHEVs ... which themselves also see many of the same benefits the HH has ... the HH is starting the race with the other hybrid tech options already having a significant head start on it.

I think I have their final report on this cpu if you are interested. Its about 82 pages of information.

Yes I would be interested... thanks
As I've said:
"I don't think there will be an 'Achilles heel' , kind of major flaw ... I suspect if designed and built right , it will perform mostly as anticipated ... including all the benefits you've listed."
Meaning ... it is not about it being unreliable in an abstract ... but how reliable will it be compared to some other alternative ... for example an electric motor ... which a group of PHDs would look at and also tell you that the principle of the electric motor is very reliable , durable , has fewer moving parts than a ICE , etc ... both would be stamped as 'reliable' by the academic looking at them ... but that doesn't tell you how reliable they are compared to each other.
Also ... reliability is important ... but like most things ... it to eventually reaches a point of diminishing returns ... once it is reliable enough it might not be worth investing in a more reliable option ... is a MTBF of 1 million hours good enough? ... ie ~114 years of constant use ... is a MTBF of 1 billion hours ( ~114,000 years ) worth even 0.1% more cost/weight/volume/etc? ... probably not... even though it would be more reliable.
