LightShip Systems Review - Aerodynamic Enhancement System

[Holdmybeer]

Hi Josh -

Come visit us sometime in Colorado and test it yourself?

Here are my rough rules of thumb, using an R1T as an example at 65-70 mph.
R1T alone: 2.5 mi/kWh
R1T with Lightship with trekdrive 2.4 mi/kWh (4% loss)
R1T with Lightship without trekdrive 1.4 mi/kWh (44% loss)
R1T with slab sided trailer (square box) - 0.9 mi/kWh (64% loss)

At lower speeds we of course do better, and while the shape of the truck matters too, I find these loss percentages to be fairly indicative.

We have offered other trailer manufacturers the chance to tow side by side with us and none have taken us up on it. We find it very hard to believe that a trailer could do better than our 44% loss without an actuated system like ours to reduce frontal area. But if you could get your hands on a Bowlus, we'd be happy to test it!

I'd be interested in seeing a Bowlus v. L1 apples to apples comparison. I'd suspect the L1 would have quite the advantage at flat hwy spds, it might lose much of that advantage in mountains where profile takes a backseat to mass, the L1 is ~twice the weight of the Bowlus. A 180 lb rider might do okay on the flat stages of a bike race, not so much in the mountains ( unless you're Jan Ullrich).

I think it is interesting to compare the aerodynamics of different towable RV's. But when you compare the actual specifications of the LightShip Atmos and the Bowles Endless Highway models the only category where the Bowles beats LightShip is the price. There is certainly a place in the market for a Bowles (at maybe half the list price) and I applaud the nostalgic nod to enhanced aerodynamics, but I just don't think it is going to make it at that price.

great point that would be an interesting experiment! being a serious cyclist myself but a pretty light guy, the mountains are where I thrive
