I don't seem to recall rotary engines being particularly fuel efficient although I guess small gas engines might edge out electric due to better energy density of gas for drones

Rotaries are absolutely terrible for fuel consumption and emissions but they excel in situations where you need max torque at steady RPMs which is basically exactly the use case for aircraft, generators, and range extenders.

um excuse me posted:Rotaries are absolutely terrible for fuel consumption and emissions but they excel in situations where you need max torque at steady RPMs which is basically exactly the use case for aircraft, generators, and range extenders. When you are designing the inlet and exhaust ports for a steady RPM application, you do that design so that the problems of the port timing overlap are negated and the fuel efficency rises considerably - having the scavaging intake arrive at the edge of the rotor just as it closes means it's not spitting raw fuel out the exhaust and the effiency is higher. Also this allows for a more complete burn so emissions of various oxides and carbon monooxide drops considerably as well. A rotary for it's power output will be considerably smaller and lighter than an ICE equivalent as well as being less complex. A steady high rpm means the engine is not subject to carbon buildup which will also lead to a better burning fuel mixture. Also rotarys run well on a variety of alternate fuels or lovely fuels

There is more to this than meets the eye I think. At first I saw the vertical rails and thought this person replaced the entire back half of the truck with a Jon boat + trailer, and used the unwanted half of the boat as a convenient topper. I now wonder though if the middle of the boat is hinged and they've turned the bed of their truck into a foldable Jon boat transport + launching platform.

Yeah, I think they're using the whole thing as a launcher, and avoiding a trailer. Meanwhile it can still be used as a light-duty pickup by just putting stuff in the boat!

Exactly my thought. If it was high enough to get into the average driveway or over a speed bump at more than 2 mph, it'd be perfect.

Front end is higher than the rear, I doubt that would be the case if this was static on coilovers so I'm going with airbags.

Speaking of, Smyth Kits made a new charger conversion kit    I don't know if I dig it as much as the first generation, I think the blocky lines of that generation lent themselves better to being a truck, but this one will have the better interior (and engine options depending on how wacky you want to get). Wonder how it would look with the challenger front clip
