Default Ice age?

Go sail, build a boat, fix the one you have, learn to tie a knot, or
sew a deck bucket, maybe learn to navigat or tat or something!

Nah; a better solution would be to put something big between the Earth
and the sun if it's too hot, a big mirror or a bunch of little ones
somewhere up there if it's too cool.

The technology and materials exist; cost is the biggie.


You are kidding, right?


Absolutely not at all.

And it actually is on topic for the newsgroup ;-)

Programmers call that "vapor ware".

And no, we do NOT have the technology for anything like that.

HEck, we don't even have the technology to go to the moon at this time.

Hey, I is one of them, too. I know the difference between not being
able to deliver a promise (vapor) and noting that something is possible
if someone wants to pay for its development (wish list).

And no, we do NOT have the technology for anything like that.


I agree that we couldn't do what I suggest tomorrow, but I'm surprised
how many advancements have been made since I last checked in, how many
creditable tests, both with sails and solar panels, how many probes
have used the underlying techniques successfully.

That they have problems getting the deployment tests launched
successfully is hardly a condemnation of the technology, given what has
been demonstrated. Hell, blame the damn Russian rockets that can't get
it up.

If you want to compare this to anything, I'd point to how much closer
we are to that than we were when JFK challenged us to fly men to the
moon. At the time, we had trouble getting rockets off the launch pad,
much less into space.

HEck, we don't even have the technology to go to the moon at this time.


The technology is proven. It's a HARDware issue!

= Not MY problem ;-)
