Re. PMS, re. "liked by women...."
Oh, I like being liked by women and men both, in the friendship department; but when it comes to the love & romance department, yep I'm lookin' for another guy. Any fellow gay dudes around here are welcome to apply.
Re. Keith McClary, re. cement:
Yes, I'm painfully aware of the energy requirement to produce cement. However, cement mills are now running on combustible waste products notably scrap tires (with major pollution abatement on the smokestacks). I expect price increases and spot shortages, but not total lack of supply in the timeframe where we will be building stuff. And I'm designing micro-houses and mini-houses where the total square footage will be small so the foundations will be small as well.
The point of pedal power to mix the concrete, is to have a simple practical backup system in the event we're in a rapid buildout when fuel costs are high or grid power is unavailable. As it turns out, it is highly likely that the limit will be 1 cubic foot per batch per person pedaling. For a small house foundation & poured basement, total about 16 cubic yards, the crew and time requirement would be: Two small mixers (for example Gilson 150-UT or 300-UT, or Red Lion RLX-3), one person pedaling each mixer, three people loading the mixers, two people ferrying concrete in barrows to the forms, one person placing & finishing (using an oldschool spading rod instead of an electric vibrator), one person spare for relieving workers who need breaks, e.g. rotating lunch breaks and bathroom breaks. Total crew size 9 people. Total time requirement, assuming a 2-minute batch cycle with this setup: 7.2 hours. The balance of the 8-hour day goes to cleaning up the tools at the end of the day.
So, one house foundation per day. Not bad. Now I just have to do an empirical test on the pedal power setup and I can mark the proverbial check in the box and go on to the next design task. At present I'm also writing a paper on graywater systems, and another on micro-house and mini-house design.
This is called being an optimistic doomer.
Quite frankly, between PO and the climate catastrophe, my moods run from scared shitless to downright depressed. Doing all this design engineering & systems development is not only useful to my community, but it also relieves the misery somewhat. Engineering mode is solution-oriented. I live my life and earn my living by providing solutions. I give myself room to feel the miserables about the problem scenarios (add to that living under a domestic tyranny), and then get back to rolling up my sleeves and working on solutions. It's a coping mechanism, one could say, and it's more productive than getting drunk or stoned or immersed in corporate media or screwing my brains out.
