I've noticed that ALL the devices I plug into my UPSes have external power bricks. Most of them are either 5V, 12V, or 19V
So, I replaced all my UPSes with LiFePO4 batteries supplied by Victron AC->12V chargers. Routed the battery contacts directly to all devices that consume 12V (WiFi AP, network hubs, SLA 3d printers). Used 12V -> 5V adapters to supply 5V / USB2 devices (R-Pi servers). For 19V, Drok DC-DC boost converters work great.
Result: threw away 3 UPSes (different APC models). Overall power consumption with AC present dropped by about 40%. Time on batteries (same Wh battery capacity) increased by a factor of about 20 (yes, 20 times: that's not a typo). Evidently, AC waveform generation is extremely power-hungry
This concept raises more questions than the site answers:
* what's the point of landing in tow? The safety aspects and the failure modes are enormous
* it's unclear where the 65% fuel saving comes from. Riding the wingtip vortex on the inside produces downward momentum. In order to generate positive lift from the wingtip vortex, the follower has to be outside of it (e.g., gaggles of geese in wedge formation)
* taking advantage of wake flows, while possible (although 65% is highly improbable), would always be less efficient than optimizing a single airframe so that it minimizes the wake generation in the first place
* the site is missing footage of real flights. The 3 clips 10-seconds long are not showing what they claim to be showing. Also, does the "see flight tests" link work for anybody?
Well, if all the interesting signals are on the mezzanine, what's the point of the Arduino form factor and pinout? Just to claim that they're supporting a widely used platform? Engineers can see through it.
The more I look at it, the more it sounds like a platform designed by M&A team
This is desperation and I think it will go nowhere good.
Arduino has neither technical (standards, form-factor, pinouts), nor mindshare among developers that can be useful for high-speed, modern and upcoming AI-on-the-edge applications.
It sounds like Qualcomm is making a belated move towards robotics, but acquiring these assets is only going to distract them from becoming a successful player.
