The Bladon turbine does not actually exist yet.SoCalGuy said:
The Capstone C30 and C65 do (exist). They are not that small (more like a beer keg) but otherwise do what Bladon claim they will eventually do. The C30 puts out 30 kW (about 40 horsepower) and the C65 puts out 65 kW (about 87 hp).
The downside is that they cost $1000/kW (hence $30k and $65k) and run similar efficiencies to ICEs. You get the same efficiency in an ICE for about $5/kW. The ICE does of course require frequent servicing, oil changes, etc., that the turbine does not, but for the GIGANTIC price difference, the fact that you have to do a major maintenance every few hundred hours of operation is no big deal, as
"a few hundred hours of operation" is months of real-time and thousands of miles of travel. Sure, the turbine will go 200,000 miles of travel before needing any maintenance ... but that means you pay for every oil change and one engine rebuild "up front".
