  • The “problem” of negative energy costs is easy to solve, but quite costly.

    Build water desalination/carbon capture and storage/hydrogen generation plants that only run when the price goes below 0; even though these are very energy intensive, they would help stabilize the grid.

    Then build more solar; you want to try to have the daytime price stay in the negative as often as possible.


  • This is a solved problem.

    DC-AC conversion is pretty well understood, as is electrical protection, grid frequency matching inverters are available “off the shelf” for small units and are made to order in the MW range.

    In NZ we have a DC link between the islands, there have been equipment failures over the years disabling the link, but grid frequency events are not an issue. The link has been in place for almost 60 years.

    Also the distributed nature of generation makes cascade failure extremely unlikely. If you have an issue in one solar farm; another solar farm a few km away is extremely unlikely to have the same issue.










  • If cosmic inflation is correct, probably not. Inflation is our best theory of the beginning of the universe.

    According to inflation, spacetime expanded exponentially from an infinitesimal point to many billions of light-years across. As far as we can tell, the universe is expanding again but at a much slower rate, due to dark energy.

    Spacetime survived the inflationary period, so it looks like it doesn’t have a “tear” mechanism.

    Another way to think of it, is to assume once torn, what is it tearing “into”. If you rip a bit of fabric, you look through to the other side, nothing special. If you tear our 4-dimentional spacetime, what are you looking at when you look “through” the ripped portion? This implies that out 4D spacetime is somehow existing in a higher dimensional reality.


  • Good choice on Mint.

    I have been using Linux exclusively (personal) since 2008, distro hopped for a few years then settled on Ubuntu, until they shot themselves in the foot with 22.04 and the snap debacle; moved to Mint (after trying Pop, MX and a few others).

    I have to say a big well done to the Mint devs, it is better than Ubuntu ever was; part of this is newer drivers etc…but it is very polished and it gets out of my way and lets me do my work.

    Been working with the various flavors of Windows in a work capacity over the same stretch, in my opinion windows peaked with XP, 7 was ok, and 10 is also ok. But it really has been down hill since XP was retired.

    2007, Palmerston North, New Zealand.

    So a while ago, and Palmy has always had a significant student population, ideas like; you can get a free feed at maccas by going through the drive through and walking / biking off; tend to spread quickly.

    When I was at university, I used to ride my bicycle to the local 24hr Macdonalds after I finished work; around 12:30am, I’d arrive just before 1am.

    After doing this for ~8 months, they must have changed the policy, I was no longer able to use the drive through. But the door was locked after 10pm, so no more late night snacks for me!

    Not sure if motorbikes were allowed or not.
