Actually, prior to 1965 both the USA and the Russians used pencils - NASA utilised a propelling pencil, the Russians used a grease pencil - which has no commensurate breakage risk.Bluebottle wrote:Don't know what space has to do do with it but both Russia and the US used exactly the same pen.
Both planned to take pencils until somebody pointed out that graphite dust + electronics - gravity = fookin huge explosion.
Not so sure the airflow is so frequently mis-managed either.
Please don't tell me it should be a foil (wing shape) again because it really shouldn't, that isn't what they are trying to do
Getting back on topic there are some problems with trying to duct heated air to high/low pressure areas.
You can also get into trouble with higher performance stuff - a broken hose could get interesting, a broken hose where you have reduced the pressure around it can boil the coolant well below 100 deg .....and send through your ducting with explosive force.
Not trying to piss on your chips, just some extra stuff to think about
I look over my screen like most have said
After 1968 the Fisher Space Pen was introduced and sold to both the Russians and the Americans.This was a prinvate venture but between the times some 12 Nilliion US dolars was excpended on the pen solution, among several hundred million technological solutions including experimentation with early versions of tablets.
As a pedant I admire such pedanticism - but it only does you proud when it is correct: The purpose of the analogy being to highlight the needless aspiration to high technology to solve what is a low-technology problem - In simple terms, stop riding like a pussy, go faster, and the wind clears the screen.
