I feel like nobody watched the video (although I do wish the article text had been clearer).

The video specifically shows (at 1:34) that the machine operates at 15Wh/L (for the larger version, the smaller version is 20Wh/L).

This is 15Wh/33 oz (since we seem so set on using customary units), or 2200 oz per kWh.

I didn't; I don't generally follow video links, unless I deliberately went looking for a video. Specifically, I don't follow many video links from HN; I treat HN as a text/plain site.

So my remarks were only about the article text.
