I don't think you're allowed to be a professor without a recumbent bike right?

The engineer there dipped a finger in the cooling goo and had a taste to show off... that'll stick with me next time I watch that movie.

And as a slight aside, have you seen how DUG do data centre cooling? That one gave me a real crisis when I visited their office in Perth...

😎 That sounds about right. There's plenty of water waste around in ag and so on for them to solve a small piece of it and say "it's all fungible, so we're zero water use now".

Drivers okay I wonder? I have a perfectly fine old laser printer but PITA to get it running on windows 10.

Hang on, I've tinkered in big compute... that really doesn't have to be true I think. Many compute loads are flexible, and could be throttled or redistributed cheaply.

Had a similar enraging experience with my super "5 years ago, sorry no paperwork"... Robotdebt, MFers!

Saw Pauline in the security queue and five fossil fuel ads at the airport... that wouldn't happen on the train.

I think people often wonder this, and it's a great question, so let me explain the advantages of 3D printing whistles. There are many.

The 3D printing effort started from one of our organizers who started by sourcing mass-produced whistles.

There's a salvage yard near me with all kinds of weird glazing left over from commercial projects... would love to do something like this.

How much do you pay in $/W by the pallet load, out of curiosity?

I was tempted to do one of the courses out of morbid curiosity... Thank goodness I dodged that, pretty much what I expected.

I have to fly to Canberra next week for work and the whole process is so incredibly miserable.

Dreaming of a world where travel is relaxed, low carbon and fun.

Oof. Well, I've seen some attempts with Bunnings shade canopies etc. but not ideal

I wouldn't put them on a north or west wall with no shade, but it's pretty usual otherwise.

You might be surprised... The energy use from blower fans and air leakage on ducted gas can be so shit that you'll end up ahead.

I'm looking at Sigenergy V2X module which will get you 12/25kW... But gotta keep asking myself, what would I do with it?! I can't export more than 5kW anyway. Maybe if you wanted the fast charging to dump a bunch of solar into the car quickly if you're not home as much.
