It's worth pointing out AEMO's demand is for the grid, and residential solar typically does not show up on the grid. OpenNEM[1] uses estimates of residential solar to approximate the full load.
Nice article, thanks. For anyone interested in the topic, I highly recommend Trefethen's Approximation Theory and Approximation Practice. It's approachable, intuitive, and fun while still covering a lot of technical detail.
I have that in the further reading section :) I personally consider it one of the best textbooks on numerical analysis.
I only wish Trefethen had written it with general C/C++ instead of his own custom MATLAB library, chebfun. One of these days I'd like to get around to implementing chebfun in C++.
This is exactly what is already done! On Earth at least. Radio telescopes around the world observe (mostly) quasars to perform geodesy. This is the main method used to measure the Earth Orientation Parameters which is need for keeping GPS/GNSS calibrated.
With it, you can measure distances of several thousand km with a precision on the order of a few millimetres. The problem is that it's really expensive compared to GPS: at each site you need a reasonably size telescope, atomic clock, some serious storage, and a way to ship all the data to a central cluster.
I think if he did have mental health problems, like many others in the field, it's now more than ever to raise the point. If he didn't it doesn't hurt to raise the issue, because it is genuine.
If you suffer from anxiety and/or depression, there is help. Talk to someone. You're not alone, and you don't need to suffer alone.
DST varies by state in Australia. Western Australia (UTC+8) does not observe DST.
