uBeam is one of tech's most intriguing startups, promising to someday charge your wireless devices through the air (or, to be more technical, ultrasonic waves). It's also controversial, with some having publicly suggested that uBeam's technology defies the laws of physics.

So there was a lot of anticipation yesterday when company founder and CEO Meredith Perry appeared at the Upfront Summit in Los Angeles, for the first-ever demo of uBeam's technology.

The demo: Perry first stood a couple of yards from a large white box emitting ultrasound waves, and used a device that glowed red when it was in the waves' path. She then grabbed an Android smartphone in a large and bulky black case, and held it up in that path. When she did so, a large battery charge counter on the screen showed that it was indeed charging.

The product: Perry says that the ultimate phone case will be much sleeker than what she showed, while a mock-up of the transmitter kind of looks like a very small satellite dish designed by Apple or Nest. There was no timeline for commercialization.

There are videos of the demo floating around Twitter for those interested (it was supposed to be off the record, but social media ultimately made that untenable). Axios was unable to visit uBeam's Santa Monica headquarters following the conference due to the company's schedule.

Next: While it appears the basic science of uBeam's plan does check out, there still remain questions. For one, the company has yet to squeeze its technology into the beautiful disc-shaped device that it plans to sell consumers. Nor the quasi-ceiling panels it would sell to commercial customers like coffee shops. Perry said that the company has recently shrunken its tech into coin-sized chips, a first step in the process.

We also don't know the ultimate distance at which consumers would be able to charge devices, the strength of charge or if there are limitations on type of device (we're told Perry picked that particular Android for the demo because of its highly-visible charging icon).

In short: This is a science project that is clearly progressing, but not nearly finished yet.

Deadly Hurricane Zeta slams U.S. Gulf Coast

Hurricane Zeta has killed at least one person after a 55-year-old man was "electrocuted by a downed power line" in Louisiana as the storm caused widespread power outages Wednesday night, per AP.

What's happening: Zeta made landfall south of New Orleans as a Category 2 hurricane earlier Wednesday before weakening to Category 1. But it was still "battering southeastern Louisiana and southern Mississippi with life-threatening storm surge, high winds, and heavy rain" late Wednesday, per the National Hurricane Center.

Fauci says U.S. may not return to normal until 2022

NIAID director Anthony Fauci told the Journal of the American Medical Association on Wednesday he doesn't expect a COVID-19 vaccine to be ready until January 2021 or later.

What he's saying: Fauci said during the interview that the U.S. was in a "bad position" after failing to keep case numbers down post-summer. "We should have been way down in baseline and daily cases and we’re not," he said.
