Hi, there, everybody and greetings from Dar es Salaam. I'm here in
Tanzania on a geothermal job.
Over a year ago, I posted a PDF of the full paper from JBIS to this group,
but no comment ensued. Look for the keywords "Dyson Dots".
We (R.G.Kennedy, E.Hughes, K.I. Roy, D.E.Fields) have been wor
Dear Robert--Very interesting. Given the time scale involved, maybe what
to be thinking about, in global climate intervention sense, is
stratospheric aerosols first as this can be done quickly, but they have
a number of disadvantages, including the problem that backscattering is
only about 10%
Such a system may outlast civilisation. How would it self correct or self
destruct as CO2 levels fell?
Would it endanger observational satellites or passing spaceships?

I should have added that it could be phased down as the CO2/GHG
concentrations were lowered or over the likely longer term they would
take than the Dyson dots.
The real problem is not that the dots would be long lasting--they would
need to be controlled to stay roughly where they are, so easy
No, Andrew it would be rather short-lived, decades, say, and even that
would require active position maintenance. Remember, the sausage-shaped
region around L1 is metastable, not truly stable. So something has to
work, albeit not very hard but all the time, to keep itself there. But

I find the idea of space-based sunshades interesting, but I'm skeptical
that it will ever be practical relative to Earth-based alternatives. Even
assuming the sunshades are indeed manufactured in space with off-world
(i.e. lunar or asteroid) resources, the prospect of manufacturing and
assembling a
Hi Folks,
The problem of launching such massive weight, if solved, would itself
provide a great deal of climate change mitigation/adaptation benefits
beyond Dyson Dots. And so, it is the launch economics which is my primary
focus concerning any space based system. Interestingly, trans-atmospher
Dear Group,
For the two following SRM proposals:
1/ orbital sunshades
2/ marine cloud brightening
Can please some one list:
a) the comparative costs
b) the technical feasibility
c) the possibilities of rapid reversibility
d) and the pros & cons
Thanks

That's two novel thoughts in two days! (launch tubes, implications of
robot/AI mfg on terrestrial mfg of geoeng. equipment) I must thank Mr.
Leahy for the discourse that his article has stimulated.
Mr. RICHTER, I'm in Dar es Salaam on a job, so please give me a couple
days to put together a
