Rules for when reducers are permitted in plumbing.

Until society starts calling things by correct names, society cannot fix the problems. I do not wish to participate in a society that is broken.

Devon Eriksen:
Most people think of philosophy as an abstraction that doesn't touch the real world, but they're wrong.

Most real world problems are philosophy problems, and most philosophy problems are "giving things the wrong names".

For example, if you call feral drug addicts "homeless people", then you can't solve the problem. You can only buy more houses for feral drug addicts to destroy.

In this case, we called the police and courts the "justice system".

But they're not. They can't be the justice system.

The function of a justice system would be to give everyone what they deserve.

Now, I deserve a hundred million dollars, a private Caribbean island, and a foot massage from Lauren Bacall in her prime, but I don't see the "justice" system lifting a finger to correct any of this, do you?

No, what we are supposed to have is a public safety system.

The function of a public safety system is to keep the public and their property safe.

If we understood that, we wouldn't care about what criminals deserve. We would care how likely they are to do it again. Or something worse.

In a public safety system, retardation and mental illness are not migrating factors. They are the opposite.

Because they mean that the criminal is more likely to pose a future threat.

We all understand this.

We all understand that the feral retard who stabs strangers on the train for being White and beautiful is a worse person than the man who murders his wife and her lover when he catches them in the act.

Not because of some abstract calculus of moral agency, of who is disadvantaged and who isn't, but because one is certainly going to murder more people if he can, while the other is a lot less likely to.

We've known for centuries, if not millennia, that it's the same small percentage of people doing all the robbing, raping, and murdering, over and over and over again.

And we've known for centuries that if you physically remove them from society, that's 100% effective in stopping them from doing it again.

The only hurdle is philosophical. Call it a "justice" system, and you have to argue endlessly about morality and redemption, and then some leftie thug-hugger weaponizes your own Christianity against you.

Call it public safety, and you confine the argument to likelihood of reoffense. Then you are in the realm of statistics. Which you can compute.

It all starts with naming things correctly, according to their actual nature.

I felled a 90ft tall large gum tree yesterday. Wow... now I know why we don't use this wood to build houses. The entire canopy of that tree shattered like glass. Every single branch smaller than my arm is broken and scattered.

Needed more chickenspace so put together one of these a frame types

LFP batteries.... These are the most common battery used in solar systems these days. Unlike other lithium chemistry they do not catch fire. Well, they can but they can't sustain the burn. Other lithium batteries like 18650s and NMC bring their own oxidizers and burn fiercely. LFP does not do this.

Now, when we talk about a battery, we are talking about a collection of cells. 48v LFP batteries are made of 16 LFP "cells". Cells are always 3.2v and range from 100ah to 628ah (amp hours). So 16 in series makes votlages add, and thats 16 x 3.2 = 51.2v. The amp hours can be multiplied by the voltage to get watthours or kWh. So a collection of 16 314ah cells makes 51.2v x 314 = 16,076wh or 16kwh.

Now we are the point that I'm writing about today.... some chinese companies are offering batteries that exceed 16kwh. If they do it with "MB56" 628ah cells, that's wonderful. But most of them are doubling the number of cells. Since they have to have groups of 16 cells, what they do is put additional groups of 16 cells in parallel. The problem with this is if one cell was to short out, the other one(s) in parallel with it would dump power into that bad cell. They should fuse them in this configuration but they don't. If things went really sideways you could have a fire from the heat of the shorted battery discharging.... but not from the chemicals in the LFP cell!

So if you are going to get a battery larger than 16kwh make sure it is the MB56 628ah cells and not two 314ah cells in parallel.

Models that I cannot recommend because of the parallel issue are Docan Dolphin series with 32 and 48kwh.

Old timers always have the best stories I cant deny.

Sometimes we find different thread shapes. A buttress thread is commonly used on plastics like IBC tote lids. Sometimes we find screw mechanisms that push and pull things and for those we use a knuckle profile packed with small ball bearings so there is no backlash.

We also find threads used on pipes. With pipes we want them to fit tighter and tighter as we screw them together. The idea is that if you tighten them enough they won't leak. So these threads are tapered... kinda cone shaped. So when you see NPT (national pipe thread) you know it will be a tapered thread.
