Wow, thanks for all the kind words and suggestions! I didnt expect this many replies. KSP sure does have a damn nice community. I'll try to get you a working prototype soon then. I experimented with adding an IVA to the hab today but no success yet, so I thought I'd start something easier for now and started making the Vasimr model. (I hope making an engine is easier... should be ) That looks pretty cool! I might try and make that some time.
