Are you assuming that the hot air is still the same temperature at the top, when the bucket turns over to let the exhaust air escape?
Which would mean that you are creating power without extracting any heat energy.
Yes, thanks for the right thinking on the project ... Alone in the beginning, I described these balloons as the largest heat engine ... ..
But you can not say that it is a heat engine, because it just does not lose heat, and gives energy ..
This escaping heat can be reused by building a roof at the top that will collect it and bring it back to the bottom of the device for refilling.
By creating good thermal insulation, the heat lost will be minimal, and only theoretically we will have to supplement the heat lost as a result of putting it into the atmosphere, and not as a result of its loss for the work.
So it's not a classic heat engine, despite the fact that it uses heat ..
