LOHAN gets hands on mighty thruster

Quick point on REHAB

If the engine doesn't fire, you'll need a valve to let air in - or "Let the vacuum out" as we always used to describe it at university.

Am I missing something?

Shouldn't the pressure (vacuum?) guage be on the other side of the valve?

Otherwise the valve might remain closed but the vessel will be in an unknown (but probably air-filled) state?

otherwise good luck getting Lohan through re-hab - it's been tried several times before, which speaks of it's success :-)

Have a question on the REHAB

I take it the plan is to seal the motor inside.

Then add the dry ice

then once workign tempreture is reached evacuate the air inside to create the pow preasure environment .

If you evacuate first would it not cause issues with the time it takes to cool the assembly ?

the otehr option is to pre cool the motor but that would make assembly difficult.

Hmm, will the vac tube have to be a special material at those low temps to avoid problem with contraction or degradation? Also, you might be able to run it up the gap between the two chambers and out the open top, rather breach the outer casing. Alternatively, I wonder if you could evacuate the chamber without the need for making holes at all by using the schoolboy experiment of boiling water (or something else?) to drive out the air, pop the lid on and allow to cool...
