  • There’s a difference between what is fair and what is common sense. If I had a daughter I would love to tell her she should go wherever she wants, whenever she wants, alone or drunk.

    In practice I’m sure I’ll temper that message with some sad but realistic advice about having a friend on the phone while in the cab and never accepting drinks from strangers.

    Motorcycle riders choose to put themselves in a much much more vulnerable state, so they have to be more aware and more vigilant. In an ideal world everyone is paying attention and awake and sober on the road, reality is different and I won’t be betting my life on everyone around me driving correctly while riding a petrol tank strapped to a motor.



  • The collateral damage from mining and fossil fuels has already done more damage to the planet than anything else since that meteor dropped in a few million years ago. I’m not worried about some kids getting scared. She knows what that company does, she doesn’t have to work there, she obviously enjoys the rewards that come with the job but now there’s some (incredibly tiny) risk she’s upset.

    I guess the moral of the story is don’t do bad stuff and no one will come and protest at your house.

    These people are used to being able to hide from the consequences of their actions behind well worded contracts and connections in the federal and state governments. She just found out how unpleasant it is when someone breaks the rules, which you could say large corporations have been doing for decades.








  • Yeah this has been a bit of a passion of mine for a while.

    We’ve got hydronic heating and I’ve always thought it would make a great way to move sustainable heat energy around the home.

    A while ago I was looking into how to make wood powered but then I read about sand batteries and started doing the calculations on how much sand and heat energy we’d need to store a useable amount of heat to keep us warm in winter in Melbourne.

    Turns out the answer is a fuckload. We’ve got a 6 star house that we built ourselves 9 years ago. we got double glazing and the high range r2.7 wall insulation and r5 or 6 in the ceiling. Its a two story house with approximately 223m2 of wall (including windows) and 106m2 of ceiling.

    I calculated approximately (and didn’t bother including windows so would actually be much higher) that we were in fact heating the whole neighborhood

    At 7c ambient temperature, and if we want the house at 22c, we were bleeding about 27670 BTUs, another way of putting it is we’d need about 8kw of energy per hour to maintain the temperature.

    In America and Europe they are building walls with an R value of 13 or 14. Here a 90mm stud wall with cement sheet weather boards, R2.7 insulation and 10mm plaster comes in at about r2.92

    We’ll never be able to generate enough renewable heat if we just let it all go so easily.

    Unfortunately, there is no easy retrofit fix. The best I’ve been able to come up with is building a second stud wall around the perimeter of the house to create some airgap but that has it’s own issues.
