Maybe you could use this in light winds with a kite and generate more apparent wind??

It's the future for sure. but at $12K USD !! Think about how many kites and hydrofoils you'd get for that money :)

This would be awesome for getting to work in the city - just park on some rich guy's lawn on Burke drive and fang across to Betty's Jetty.

Yeah incredible invention , there is a video of the efoil towing in another foiler onto a wave it has tons of grunt (sorry can't find video) One hour run time at 15mph (max speed 25 mph) with 2.5 hour recharge. 12k US plus another 1K US for a spare battery (1.5 hour) they are Tesla batteries . Add to that freight , duty , GST. That's almost 20k Aus landed. Price of a JetSki . Limited market but Nick is sold out on first run. 6 month wait for second run.
