Re: Old oil for the turbo

Turbopumps are so fragile and expensive that I would not dare use an uncertain oil (except oil that's positively identified, but moderately expired).

Re: Coronavirus pandemic

I got my sputtering system set up for sputtering titanium (in a manner of speaking).

Re: Update on experiment

I am honestly a bit skeptical of that pump -- not that its a bad pump, but that there are probably better ones for a lower price.

Yes, LDS specifically is oddly expensive for shipping charges.

Re: 2 papers about 3d printed vacuum parts

Sadly, laser-sintered metal prints are insanely expensive.

What about printed ULTEM or PEKK? Both of these are available and (somewhat) economic from Stratasys Direct.

Re: Australian Breakthrough Fusion (Duh, Chirp Lasers)

I think there are much better things to do with IC pulsed fusion than generate electricity.

Re: Loads on roads

All I know is that it's incredibly fluffy. A litre of water has more hydrogen than a litre of LH2.

Re: McMaster Carr's oddly inexpensive turbopump

I'm saying it's oddly inexpensive for a brand-new complete turbo, gauge, and roughing pump set.

None of us have brand new turbos, but I still found this quoted price a bit surprising compared to others.
