Baluncore replied to the thread Ferris Eugene Alger.During wartime, patents were selectively classified as secret, and not published, to prevent the enemy from gaining the information.
-
Baluncore replied to the thread I How feasible is home radio astronomy?.Given the RA, Dec of a source, a fixed EW array of two or more elements could be constructed with that declination. That array would...
-
Baluncore replied to the thread I How feasible is home radio astronomy?.It is good that you are now recognising that the receiver front-end needs to be at the focus. I agree that if you pull back your...

Baluncore replied to the thread Cooling a processor chip.If the fluid is pure water, then the capillaries that wick the liquid water back to the hot end, will need to survive ice wedging when...

Baluncore replied to the thread I How feasible is home radio astronomy?.It does not have to use cryogenic cooling, a stack of Peltier refrigeration modules will do the job at the focus of an amateur RA...
-
Baluncore replied to the thread I How feasible is home radio astronomy?.I warn the neophytes of how steep the learning curve really is. It may seem easy to engineer an amateur RA observatory, for some...

Baluncore replied to the thread I How feasible is home radio astronomy?.I maintained and operated a radio astronomy observatory before I retired.
-
Baluncore replied to the thread I How feasible is home radio astronomy?.By virtue of the cosmic noise it receives, every receiver that is connected to an antenna, is doing some radio astronomy. The band...

Baluncore replied to the thread A practical way to vaporize fuel for high MPG?.There were one or more tricks involved in the 100 mpg demonstration with that big V8. Maybe the wind direction changed midday, so there...

Baluncore replied to the thread A practical way to vaporize fuel for high MPG?.My guess is that the engine employed a gas mixer, like on an LPG fuelled vehicle, but produced the gas by boiling high octane gasoline...

Baluncore replied to the thread The usage of dipole-dipole array in Lumpur Sidoarjo (Lusi).I think the mud is probably marine, originally volcanic ash, washed into the sea. That mud will probably be more conductive than the...
