I've been following since day 1, along with the Airwave.

It's now become a full scale prototype.

It's already proved the smaller test waves in the tiny tanks and other larger models can be scaled to full size, thanks to some smart engineers and scientists/surfers/investors. The potential is amazing.

It they can get this reliable, then commercial models pumping out 8ft waves over 5 breaks, left and right, 6 sets every minute, It destroys everything we thought about wave pools.

Instead of flogging a sled underwater consuming HUGE amounts of energy, you can just bounce a 900T plunger on the water, only needing a burst of compressed air to keep it's momentum going once underway.

They have a long way to go. But early results show its possible. Stab have an excellent 5 part (so far) story on it. Beach Grit are trying.
