    It's good to see such a big turnout.

    All the same, the fans might not help if all they do is recirculate air at 36°C. If the atmosphere is dry, then they can accelerate evaporative cooling, but not if the air is already humid.

    There is also the issue of acclimatization. When I first moved to Brizzie from Wellington, I found the weather very hot. But after a few years, I would be wearing longs in the relatively cooler months and see visitors wearing shorts.

    Hi All,

    I hope everyone had a safe and merry Xmas! I appreciate the feedback and I will work on improving for future events. I understand QLD weather is very hot and I will take this all in stride, as I have only ever acted in the best interest of the chess community. Providing opportunities for chess in Australia to thrive and grow is my greatest mission!

    Due to the large turnout, I had to secure a bigger space and Buranda State School was the best available. There was a lot of work that went into all of this, so please consider the great lengths it takes to run and organise such an event. I had plenty of inquiry’s about air con and was always honest with those and mentioned that there’s two industrial fans and bottled water. From the 95 participants, I have heard one formal complaint about the heat. Nevertheless, if there is anything further I can do to help, please let me know. If anyone wishes to discuss this further, please email me at alexstahnke@topchess.com.au. I will no longer be responding to this thread.

    Until next time, I would like to wish everyone a Happy New Year! Cheers, Alex.

    I consider this event to be one of the great initiatives of the year for Queensland chess, striking out boldly where no other entrepreneur has been before and obviously meeting a need that has not been met before with its magnificent 95 participant turn-out on the eve of Christmas.

    It's much easier and risk-free to promote the 50th-anniversary event than the inaugural one, all parties benefit and no one loses.

    "Hasta la vista."

    The Buranda venue appears to be a school hall, which would be difficult to air condition properly. Most schools have at least the libraries air-conditioned, in my experience.

    This issue was previously raised at a CAQ Council meeting, where there was a proposal to make air-conditioning compulsory for all venues, but I don't know if it ever passed.

    You've got the physics back to front. Fans will help with humidity, as they'll promote evaporation of sweat and therefore cooling - as long as it isn't too hot or too humid. But they'll do nothing if the problem is the temperature rather than the humidity. In this case, I suspect that it's both, when air-conditioning would be the only real solution. Although an evaporative cooler might help - much cheaper than air-conditioning.

    But I just said:

    they [fans] can accelerate evaporative cooling, but not if the air is already humid.

    You don't have to disagree with everything I post. You might want to find out first if you really disagree in the first place.

    Sometimes if the air is hot, opening a car window feels like opening an oven door. There is a reason why convection ovens have advantages. So if it were too humid for evaporative cooling, the fans could be counterproductive. They could have a place if the inside were warmer than the outside because of all the live human bodies, if they drew hot air upwards rather than blew it back down.

    I'm only disagreeing because this is an important practical issue. And with global heating, it will get worse and worse in Brisbane (as I've already explained to you elsewhere).

    If the humidity is so high that sweat won't evaporate, then you definitely won't be playing chess because you'll be dead! So fans will always be useful, no matter how high the humidity. But with high humidity, evaporative coolers won't be very effective in cooling the room. However they would still be better than nothing.

    Being sensitive to humidity myself, I certainly sympathise with Tony. But it was really just bad luck that the event coincided with some of the most unpleasant weather we've had in Brisbane for a while. If the event had been this weekend, for example, there would have been no issue at all.

    Not that I need any explanation from you on topics involving physics and chemistry.

    Come off it. Steam rooms are hotter than that, 43–45°C. Not that I would want to stay in one for longer than 15 minutes at a time.

    I would have also found it highly unpleasant.

    Here in Atlanta, it is quite warm for winter, but it was around freezing a few weekends ago.
