Their website is https://wi-gl.com/
They presumably only use wiglinc.com for email, but the least they could do is set up a redirect to wi-gl.com

And it looks like they're looking to raise another $20M again.

Isn't that continuation of the video I did a while back?

It is. And they raised another ~$900k from the date of your latest video, unbelievable. The funniest comments in their Startengine page are from the scammers with $30M in a bank looking for someone to help them transfer the money  :-DD

If I may, one thing that you didn't cover enough, is that for energy harvesting, the big receiver antenna *and* the big capacitors must be in the device being wirelessly powered. Want to charge your smartphone? Either buy a smartphone 5 times bigger than today's, or carry with you a WiGL gizmo that harvests power and every now and then you connect it to your phone to dump the energy in the capacitors. Or, you know, you could buy either a smartphone with a bigger battery or one of those "newfangled" power banks, which will be much smaller than any WiGL receiver (and work much better). They can talk about future development all they want, but the antenna size can't be reduced without directly impacting the power receiving ability. So any wirelessly powered WiGL device must be big

Also, a smartphone with 10mW will not charge. Will just discharge a tiny bit slower. So the 5x bigger smartphone idea won't work either, because even assuming you can continuously stay in the sweet spot at 3' from the charger, you still get less energy than the phone uses in standby
