Company claims to have created zero point energy device called E-Cat

This company is claiming to have created a energy generating device that requires no fuel and has no emissions. They claim to have attached this to a small EV, which allows the EV to run continuously without a charge.

They did a 6 hour test comparing two evs, 1 with the e-cat and the other without. After two hours, the normal EVs battery died, but the other vehicle kept going for the full 6 hours before the concluded the test.

At the end, they claim the e-cat vehicle actually had a hire battery percentage compared to beforehand.

This should obviously be taken with a grain of salt as these are wild claims, and from what I've seen so far they haven't explained how it works.

I'm interested to see others test this to verify reproducibility.
