spinifex: The aircraft are doing a tremendous job under very tricky flying conditions.

Chloe: All the burnt leaves and the strong yellow colouring of the outdoors has been strange, a very eerie feeling. Sending my thoughts out to everyone effected. I couldn’t have windows open due to the smoke around today, was bad enough

spinifex: We have another Catastrophic fire day looming on wednesday. 43 degrees and high winds. And it isn't even summer yet.

SA Hunter: Hi all - still away, expecting 43c & windy too. Looks ominous!
Nov 18, 2019 19:05:02 GMT 10
SA Hunter: Hit 45c at home, 80kph winds. And of course, to keep electricity supplied to the big city Adelaide, our power was turned off till catastrophic conditions ease!!

spinifex: Interesting that the Adelaide Hills, also with catastrophic conditions, and many more large trees in close proximity to power lines, has had the power ON all day. I think calling our regions power cut a 'safety measure' is BS.

spinifex: Had the genset running all day keeping power up to computers, phones, fans and fridges. Spent the late afternoon at the beach ... which was very refreshing.

SA Hunter: Got my genset ready to go - but, can't find the key-turned the house upside down-nothing-grrrr.

blueshoes: G'day everyone, how are we all going? In Gippsland, it's "Summer" - 2nd December, 8 degrees and pouring rain...

blueshoes: SAH did you find your keys?

SA Hunter: Hi blueshoes - no luck!!

I have some knowledge and thoughts there as I spent a bit of time looking at various options, this from the top of my head.
20W/h when you're hiding inside, possibly useful. You might not for instance want to show panels on the roof to remain hidden, or if you were in a bunker, they might be your only means of power. It's small, clunky, a little heavy to put in a pack, though will give you something. Canadian prepper [youtube] did a review on it a while back. The other side of it is a 10W panel will get you about 25Wh/day [winter], folding ones are cheap, one piece ones are cheaper. Depends on application.
Your average human can generate about 70W/hr and probably at about an hour of endurance for most, with a bit of time and/or fitness increase perhaps 6hrs a day could be done for about 250-400Wh/day. You'll get some losses in conversions though lets just go with that. You can hook up an exercise bike with a 200W 12V [well it could be any voltage but you need to match with the regulator and battery] scooter/bike motor with a sprocket, the speed should be about right for an exercise bike [make sure it has a chain], and if you can use a welder or even lots of screws/pop rivets you can attach it. The more suitable bike would be one with a flywheel such as 'circuit bike'. Use a MPPT solar regulator [$10] and you've got a 12V charger, charge a battery. Bulky, but if you have an exercise bike, you can make a bracket you hook it up with if you ever needed to. I have the kit ready, though I have not welded it up in case I sell the bike [which I'm contemplating], but the brackets, wire and regulator are all there ready to be installed. Do I think it would work, absolutely, do I think it's better than solar, nope. What it does do is give a stealthy way of making a useful amount of power and I'm a little challenged as to it's utility compared to solar due to the extra costs in food of about 3000kj/hr.
I'll need to look up the reference, but this reminds me of a wealthy chap in the last couple of centuries or so - he hooked up a revolving gate at the entrance to his property to a water pump, so every time anyone entered they would pump water from the well into a water tank.
Apologies for the vague lack of detail, but it's an interesting concept. What if human effort could be used to inadvertently provide power/water flow/etc?
Of course it's not a lot of power, though the idea of a daily win-win would indeed help them understand most of society better, rather than what most criminals know, aka win-loss [which usually comes from child abuse and I digress].

Fascinating. I always wanted to build myself a human-powered generator of some sort with an old stationary bike but don't have the intellect to figure out how. Would be good though as it serves a purpose as well as keeping you fit and ready, I wonder if there are any guides on how it works and how to build one.
