Sounds like they had some success, I wasn't encouraged by the start of the video though. We'll see.
Keep in mind that the XChallenge is a specific test to extract oil off the surface of water. The Voraxial can do that, but it can also do many more things. It can be submerged at depth and could probably be used on the floor of a factory or next to an oil well on land. As far as I know, none of the equipment in the contest is as versatile as the Voraxial. A Win, 2nd or 3rd place would be nice, but either way, long term, I like EVTN!
This is truly innovative and the company is just lifting off the ground!
