The author of the phenomenally successful 'Life, the Universe and Everything' was, said his agent, decidedly incapable of capitalising on the success without being goaded and forever in search of 'displacement activities' in an effort to avoid writing... or in my case wiring.
Accordingly I try out much the same framework in support of a mono ski instead of a catamaran. The two-metre chassis weighs 6.50 pounds, or around half, whilst suited to a single motor so long as a rudder is added to compensate for the torque effect. I could of course add a contra-rotating propeller, but that is altogether the heavier and more expensive of the alternatives.
Interestingly the outline dates back to a patent I originally filed back in 2011, and goes to show how technology often catches up with ideas. Thus as the internal combustion engine caught up with our ongoing efforts to fly, the electrification of transport opens up opportunities that at one time looked rather less practical.
All things come to he who waits... though that's true of death too.
