Disagree.
For certain applications, including having “fun”, 10 mins is a significant amount of time. It is also orders of magnitude better than anything before it. A light person could also carry more fuel, so it isn’t a fixed 10 mins.
I could see this being useful in rescue/emergency situations where you need to quickly get to a difficult spot. Somebody might be able to help in a situation where a helicopter isn’t an option. These could be made inexpensively in bulk.
There’s probably other applications too, doesn’t have to be for a typical users commute.
Why, with enough fuel, it could probably lift Michael Moore for almost 2 seconds!
