Create motivating demos of CoT streams

[matthias-samwald]

Create non-trivial, motivating demos of CoT streams for outreach and tool testing.

This should also include 1-3 examples of biomedical CoT streams with a few re-starts for each input to serve as a basis for the work of @Llewi

A general-domain example I recently came up with for a presentation:

Question:
Could Austria cut thermal power production in half if it doubled renewable energy production?

Chain-of-thought:
If energy demand is constant, any loss of energy production needs to be balanced by a gain in energy production.
In the year 2020, 21% of energy in Austria was produced through thermal power. 18% was produced through renewable sources.
Cutting thermal power production in half would result in a loss of 21% / 2 = 10,5% of total energy.
Doubling renewable energy production would result in a gain of 18% of total energy.
The loss could therefore be balanced by the gain.

Answer:
Yes.
