I like the potential of this (lake wave machine for use in water sports)

It's still early days, no idea what mess it kicks up, nor how it's powered.

But bringing sport outdoors into nature has always been good in my book
Ka'ana wave co launched it at a whistler area lake beach party Britannia beach),

The model, CM7-series can produce 4 foot wave shapes.

Might be a good move for reservoirs who have bunged up seasonal inflatable water parks, wouldn't say no to a solar array powering this.

When I was a lad & used to barefoot water-ski this is the sort of kit I dreamed of, barefoot was pretty much a no no in the uk for a variety of reasons, least of all an expensive mastercraft flat bottom boat or similar, surf wave pools have become a cruise ship novelty so I hope this gives better access to the many where outdoors is concerned (& usually a desire to keep the natural surroundings intact)
