With the rise of household electricity in the early 1920s, people were making all kinds of predictions about the way that it would affect our lives. But it looks like one comic artist from 1923 thought that one day even humans might need volts to stay alive.
If we take a rather liberal interpretation of this idea (ever feel anxious and out of touch when your phone battery's dead?) we could argue he wasn't half wrong. And ice cream pops delivered via radio signal? Doesn't sound like such a bad future to me.
