With the fuel cell, it was very pleasant to see the glow of Vavilov-Cherenkov, but it is still a pity that the activity does not increase with close contact of fuel cells.
In the observatory, you can put a generator with RTG as fuel, you can use a fuel cell in it, as a minus of RTG, you can add an increasing radiation background as a result of long operation and overheating.
ADD A TROLLEY for an ATV, tired of riding with a box on balloons.
