What was the point of the technodrome?

[Jelly Bean]

The stupid thing never worked most of the time and most of the episodes where about finding fuel or getting it unstuck. For a massive war fortress the thing was pretty useless. Krang and Shredder never had enough power to keep it running and it was falling apart most of the time. Why did the creators even bother having the technodrome in the story if they couldn't even have it work half the time?
