It sure would be a good idea for some suitable person in our community, to submit an abstract/plan to give a paper at this conference --- to make the case for SPS as a major source of dispatchable power, to help reduce GHG emissions, to mitigate climate change.
Obviously one of the major justifications for SPS is to help with climate change. However, as far as I can tell, the world climate change community is almost completely unaware of SPS as a serious major power source. Presenting at this conference could be a good opportunity to raise the topic, and work on planting seeds in the minds of climate-change-type people (instead of just preaching to the SPS choir).
Of course, doing so would take time and money, to prepare a talk and attend the conference…

Hi Erinn, Kieran, Howard, Keith, and Tim,
This abstract is quite ambitious. It is a good overview, and could even be a feature article in Scientific American. Your stated target for GLOC is Session 3, addressing “systems to address climate change”. The primary focus of Session 3, however, is “earth observation”. I imagine the organizers recognizing the value of satellite observation and measurement. SSP is likely to blow their minds!
While I agree an introductory article is important to this new audience, we may need a second paper specifically focused on metrics, and submitted to Session 6 on “space technology”. This companion paper could assess GHG emission reduction as a function of SSP deployment. It might include atmospheric warming from absorption of the power beam (small, but non-negligible) and be compared to fossil fuel energy, both as a function of scale. And, most importantly, it should address EROEI – Energy Returned on Energy Invested. Even as launch costs come down, the energy required to loft hardware into orbit remains enormous. We could also contrast space-based manufacture of SSP components to those launched from Earth as a Gen 2 solution to even further mitigate climate change. I’m picturing graphics that illustrate the enormous leverage of space-based energy solutions over terrestrial options, including fossil fuels and the intermittent sources of ground-based solar and wind which require storage to be baseload. And, if we can tie these studies back to specific climate metrics such as sea level rise, I think we could “steal the show” in Oslo.
What do you think?
Peter

erinn, you are amazing.
GLOC sounds very promising.
see if the enclosed edits work for you.

Possibly, though it will take more than updating.
The problem is that I had assumed human workers for building power satellites.
Just after 2016 it became apparent that the space junk made building power satellites in LEO something that you really didn't want to do.
And if you go high enough to get out of the junk, then the radiation from the lower Van Allen belt kills your workers in a few hours.
The whole construction has to be robots or teleopation. Keith
