I was gong to post on this point - in RCEG both the RC Ragtop Air-Raft and the Sensor Drone use Heplar Coupled with an MHD Generator. In the main rulebook the Air-Raft, G-Carrier and Enclosed Air-Raft have the same set-up.

It’s funny but I always thought that HePlar vented well plasma not fusion by products. Is there a bit missing in FF&S regarding HePlar in relation to what types of power plant it can be used with, as written you could attach a HePlar drive to any power plant (mental image of a steam engine powering a ships maneuver drive – Space 1889 variant)

The primary coolant that goes through the core passes heat to the
secondary coolant that goes into the turbines. That's the same premise
with HEPlaR. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
I don’t agree with this premise.
HEPlaR or High Efficiency Plasma Recombustion requires a heat exchanger recombustion chamber. Hydrogen is injected into the recombustion chamber and the power generated by the engine (fusion power plant) heats the hydrogen to a plasma state. The plasma is then released as a high velocity stream of reaction mass (FF&S Pg 70)
Plasma is made and sent outside the ship to provide reaction mass and therefore thrust for the ship. SO how can you say that fusion products are not vented? The fusion product of plasma is vented and yes it is radioactive, though only for a short time.
Enjoy!
