I used my PC to wake up my android phone; there a Google thing that will make it don’t for five minutes even if it’s on silent. The two times that wasn’t easily accessible, I asked someone nearby to call my phone. Once I found it immediately; the other time, I found it later from the “missed call” beep.
I like the idea of this match, but I’m cautious about the article. All they say about the gas-powered boat is that it’s a similar size; they don’t mention the actual type of boat the chase boat was, and I didn’t see it in a brief skim of the video. I suspect that a notable percentage of the electric boat’s efficiency is due to its being a hydrofoil. If the gas boat is the standard hull-in-the-water, it would naturally be less efficient.
