Ham Radio will save us all. Not. Well, at least, I have a full boat anchor station (all vacuum state - tubes) which should survive an event. The problem is that the station hardly survives a single use, when I have to go and find out what broke again. But that is me. What about everyone else? And what about food and water? Oh well.

a "Hamstick" antenna for 20 meters is only 10 feet long. Also, you can get a decent SSB tranceiver for about $250 if you are willing to use an aptly named "boat anchor". ON a boat. Get it? hihi.

Could we have some more details on this???? I would like to know too. SSB? dont you mean cw?

No wonder why it was impossible to remove. My Windows 2000 machine is most probably infected and will probably stay infected until I just reload windows from scratch. Maybe even that won't get rid of the adware.

Easy. Just get a small black hole. Shoot the photons around the gravity well. They'll last almost forever.

A very late comment....

When the state of the art robotics is advanced enough for robots to automaously go and create factories for making more robots....

Then the only limiting factors are
a - raw materials
b - energy

Both of which are virtually unlimited in space, i.e. the moon, astroids.

No comment needed on the implications of an unlimited and cheap work force.

Secondary question - how many humans are needed (on Earth or off) to insure the species and for progress, once working becomes obsolete?

"...Although the atmosphere of Titan is filled with a smoggy orange hydrocarbon haze..."
Just like L.A. Let's go there.

I always wondered why my chemistry set was lacking the ONE chemical that I really wanted.
