Fill her up!

Three men discussing how to fill the generator of unit EC 20 with hydrogen; Eddy, Wytze and Eric.
We have a lot of systems running quite good now and today we prepare the generator for start-up.
That means: displace the ambient air with Carbondioxide and after that we displace the carbondioxide by hydrogen.

It's a long time ago since we did this so we have to be sure... Hydrogen is quite dangerous stuff (in combination with air)
At the left: the so-called Lunar Explorer; the storage tank of the shaftseal system of the generator.
