The SOLO engine is quite interesting.

The output performance can be adjusted by the working gas pressure between
40 and 130 bar in the range of 3 to 9 kW (mec

(Note the 3.25 fold pressure increase generating a 3 fold power increase)

It is diminishing returns. For each extra bar of pressure a lesser gain in power is achieved.

The first bar increment achieves the biggest power increase.

My suggestion is that, for our boating needs, we should have a few bar, use helium and
maybe have two cylinders. The cylinder swept volume is then another option to “marry”
power vs size, effort and complexity.

A sufficiency of variety.

BUT!............. Make, MEASURE and modify.

The swept volume is 160 cc
