Just wondering about the power requirements for an eFoil. Considering Kai Lenny can paddle his foil surfboard sufficiently to get riding, perhaps the power requirements are much less (when there is a following swell perhaps). Robert Forstermann the german track cyclist "only" puts out about 700-800W as a sustained effort - I'm referring to the video when he powers a toaster enough to toast a piece of bread. A human paddler would be outputting much less. The Wavejet surfboard produces 20 lbs of thrust (2kw i believe) and is sufficient to propel a surfer along at 10mph apparently.Starsky wrote:Will work for real surfers first, Those who can paddle into a swell to help the motor out and hop up to standing.
Inlanders you'll will need a winch, bungee or tow.
It seems that both power and battery voltage escalade are very likely to occur.Jzh_perth wrote: The Wavejet surfboard produces 20 lbs of thrust (2kw i believe) and is sufficient to propel a surfer along at 10mph apparently.
55 lbs weight and 15 Kn /maximum speed for less than half an hour is boring and $10K is expensive.Europ2 wrote: http://www.waterwolf.de they have the type of water thruster we're after !!

I don't think you could really minimize the weight and 5 kW power expenses of an HF with our "Techno-Logic",
especially when you'd like get a dissent 25 - 30 Kn speed, where the fun starts.
