[Lex Computer & Tech Group/LCTG] Climate control by bubble shade at L1

[Ted Kochanski]

Weather [or whether] or not you have a concern about human-induced or
exacerbated "global warming" -- putting artificial reflectors in non-near
earth orbit -- sounds like the most dangerous "junque Science"  / "Junk
Engineering" of all time
If you put something out at L-1  which is dispersed IN 3d -- try to
retrieve it if you made a mistake in your modeling!

Google project West Ford -- a DARPA plan to build an artificial
Ionosphere out of copper needles^1 to insure long-range communications in a
WWIII scenario
The only good thing to come out of the proof of principle phase of the
program was the construction of the the small Westford antenna^2 on the
Haystack grounds in Westford  -- hence the eponymous [love that word]
project West Ford -- later used for a number of experiments as a 2nd
antenna to the Haystack dish to disambiguate data

The needles were placed in medium Earth orbit at an altitude of between

2 from the Haystack Observatory website

Westford is an 18.3-m broadband VLBI radio telescope currently operating in
the 2–14 GHz frequency range. It is protected from the elements by a
28-meter-diameter, air-inflated radome constructed of 1.2-mm-thick
Teflon(TM) fabric.
