Although it doesn't specify, I would suspect that this is a turbine design, not a piston design. I've seen a 30kW steam turbine that wasn't much larger than an AC compressor for a car. Add a heat exhanger in the exhaust manifold, and it could be quite compact. Of course it was also noisy enough to hear from a good 200 feet away, and would require a geared stepdown drive to provide useful torque -- I think it ran at 20,000 rpm or something?
