This is a most excellent place for technology news and articles.
It's trivial to get a 240v circuit installed, even an electrician apprentice can do it with their eyes closed. Alternatively, you can install a battery bank that discharges at >120v while being plugged into a 120v circuit.
And it's not trivial when you don't live in a place that allows for you to do that, which is what this article is alluding to.
