The supposed EV that would be charged by their device and would undergo a test run for 12 hours without recharging externally doesn't work:
They've cancelled the demonstration without a future attempt date, and without explaining what went wrong or what they're doing to resolve the issue.
The pre-order is laughable - they want 1 million people to pre-order a device they have never proven in public, nor given out to an independent third party to evaluate. Quite frankly if their device worked they would be able to seal it into a box to protect their "intellectual property" and it would simply provide 100W of electricity continuously. All the third party would have to do is provide a 100W load, measure the output, and weigh and measure the physical characteristics of the box. As long as it put out more power than the most efficient battery available at that weight and volume over the measured time period the claims would be verified.
Since they cannot do that without exposing the scam, then it should be plainly obvious to any sane individual that their product doesn't do what they say it does.
As far as the 'free' pre-order, they set the volume of orders required before selling them to prevent them from having to produce anything.
Eventually, as these types of scams typically go, they will contact their victims and claim that they are close, and ready to accept a "small" pre-delivery fee.
You can tell when a large scale public scam like this is nearing its end, though, because they've run out of government and business organizations willing to give them money without proof, and they are now trying to scam the general public to continue living their lifestyle and persisting the scam.
It's quite amazingly, actually, that they've held on this long and still have people willing to promote and defend them with absolutely no proof.
