This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Rubbish dump methane to electricity is cheap and effective. The Canberra mugga lane tip has had a pilot plant~~, not sure if it's still running~~ generating 37 GWh a year
Hydro on the mainland is pretty much just Snowy Hydro. There was a project from a former government to make that pumped hydro. I don't think it has yet been finished. I don't know whether the project has been cancelled
37 GWh, now that's a "random" number
Solar thermal - yes, the leading technology is a field of heliostat mirrors focusing sunlight on a tower, melting and heating salt. That system can easily hold onto the heat in their salt for use at night
CSIRO in 2014 thought it was possible. I trust they did the maths right.
