It is possible - I know that my bank had threatened me during my study times to take actions because my bank balance was constantly oscillating between + and - 400 at the end.

Yes, banks are wonderful when you have money. Don't want to know when you need money for a new roof...

Exactly... They love giving out loans to people who actually don't need one. But if you need a loan.....

Hardly surprising that the economy is going down the drain now, because many companies started to learn from the harsh treatment by the banks in the past and use their own money in first place.

I hadn't thought much about banks till I did need a loan. The group of flats I live in has a service charge, as usual, for ongoing maintenance. Obviously, major repairs are needed occasionally, and the freeholder decided we needed a new roof a few years ago. It came to 7000 each.
I didn't have that sort of money lying around, and thought it would be easy to get a loan. I've paid my mortgage off, never been in debt, had a good job, got a good pension. Asset rich, cash average.
I won't bore you any longer, but no-one would lend me the money. Wouldn't lend me half! Seems I don't have a credit rating, as my credit card isn't used much.
Taught me a lesson, and I now have several gold bars under my mattress...

Sadly, such a 3D printer is a tiny bit on the expensive side. Especially in terms of electricity... I would know quite a few problems I could solve by simply using a laser sintering device here. Especially problems regarding old motorcycles. But a SLS printer currently starts at 9000€ .... for a professional system, I would need to sell my car and potentially also a kidney.

I have been looking at 3d printer kits, lot out there, but too expensive at the moment. Worth keeping an eye on, good fun to play with I think.

On another note, can anyone see anything happening in the rocket test video in #51 above? I see a flare-stack thing in the background, but nothing around the engine.

Not much to see there, because it is a turbopump test, but you can hear it. Also it looks like the methane is pumped into the flue stack, with a reasonable delay it really gets hot there.

Now I want to do a BBQ.

Shame, I like to see a bit of hot gas! Wonder where they are putting the gas-generator exhaust?

I would say into the long tube running out - Methane and 2xO2 burn into 2xH2O and CO2, at proper temperatures. Both should be invisible.
