Notice on NDB's website the big words "INVEST NOW".
https://ndb.technology/This reminds me of a very dodgy character named Rick Mayne who "invented" a revolutionary car engine under the company name Split Cycle Technology. Split Cycle Technology claimed the spilt cycle engine was "tested by NASA"
. When the split cycle engines went nowhere, Split Cycle Technology worked on a new invention and went about raising more investment funds: air powered bicycles. Pump in compressed air into the bicycle frame and use that as a source of motorised transport
. No surprise Split Cycle Technology came out of Queensland. And the whole lot went bust as Mayne walked away with a fortune.
