Might be fuel efficient (which I kind of doubt - thermal losses), but
seems pretty heavy..

"Fuel is compressed in a compression cylinder and transferred
to a power cylinder through a gas passage."

I don't think so :)

The 60 % efficiency seems 'definitely' unrealistic to me. Where would
that come from?

Anytime I see investor information on a web site claiming
unreasonable results runs up a red flag on my flag pole :)

They talk about 100:1 compression ratios without talking
about the structural weight implications. Also no mention is
made of the size, volume and weight of the compressed air tank
required for storing braking energy in the hybrid configuration.

The volume of the cross over pipe must be in the compression
ratio calculations and it is never mentioned. When the valve is
opened this pipe must be pressurized lowering the air pressure
in the pumping cylinder and consequently that pressure
transfered to the combustion cylinder.

Disk valves are nothing new. They still have the same problem
the slide throttle has. Under high pressure they tend to stick
as the high normal forces on the disk are hard to seal and deal with
particularly on the hot combustion cylinder side. Felix Wankel
designed a disk valve V8 torpedo engine in WW II.

The 60% claims stems from the hybrid nature of the device
in the automotive driving cycle.
Braking energy is stored in the form of compressed air to
be used later to accelerate the vehicle. On a steady cross
country run on the freeway it is no more efficient than
any other four cycle piston engine.

Off set cylinders from the crankshaft have been used
before to cut piston skirt friction.

What is significant here is no hardware has been built
let alone tested. The devil is always in the details.

Another stock scam pure and simple. There is no law
against declaring bankruptcy after you have squirreled
away the money from selling stock.

BTW I noticed Inodyne was missing from Sun n Fun this year.
