Is that real weightlessness or the same as you can get in one of those Russian transport planes for $5k ?

Don't shout this too loud or we'll have Prescott's mob doing part

[Mike]

Is there a prize for real orbit then ?

[Mike]

sure someone would be

practical. Current LN2 generators

need a lot of air.

of the air comes out

expensive if all they are

rotational speeds of the air

That's alright then, just up the voltage on one of those new Dysons ;-)

[Mike]

That's probably how much NASA spend delivering a kilo of lunch to a meeting room :-) Good luck !!!

I think there may be. Not sure.

Yep, last one I bought only went up 10 miles before burning out. I was gutted, it cost 25 quid. :((

Not really, any water in LN2 freezes so cold it sublimates away. CO2 freezes solid and in some situations can by seen as a frost on the walls of the Dewar or rolling around on the bottom as nodules.

I don't know if you saw my post. I'm fairly sure you'll need 200bar for the air. The heat given off compressing air to that amount is huge. And needs to be removed before the compressed air enter the low temp part.

I'm fairly sure the fridge kit is only good for a few bar output.
