My hope for America is once Optimus robots are up and running, have 1-2 legions worth work 24/7 setting up a huge farm in Arizona, then creating an energy transition line to the east coast. It sounds crazy, but given the rate of advancements in robots and the fact that solar panels are already mass manufactured, why isn’t this feasible in 2 years?

Setting up huge installations in the desert is already nearly labor-free. Anyway this article is about small installations.

Does anyone have a good link/step-by-step for doing some sort of home solar system where: - it's sufficiently small-scale that no building permit is required - it looks nice enough that neighbors won't complain - the wiring is essentially plug-and-play The best approach I've been able to come up with is to purchase a medium size battery pack such as is used for glamping (glamour camping), plug it into the wall and co…

Some resources:

Note: You'll probably need a permit for the electrical work if it's more permanent and/or grid tied.

But watch the video at https://www.mobile-solarpower.com/mobile-48v-system.html for something similar to a Goal Zero or Jackery

> no building permit is required

This will be the main issue. No matter what you're going to be doing work inside the main service panel on your house adding new feeds and you'll need to install a transfer switch to disconnect your house in case of a power outage. Most electrical work inside a panel like adding circuits will require a permit in the US. Seems like your plan doesn't involve any of that though so you should be ok permit wise except maybe needing one for the pad and structure.

In Europe it's somewhat common to have a small solar panel just on your balcony (i.e. not permanent attached to the building) and simply plugs into a nearby wall receptacle. https://www.theverge.com/24150901/ecoflow-powerstream-review... For those wondering, the article did discuss the safety matter of using a power outlet as an inlet. And the article also points out that while this is allowed in several countries in…

Wild. I wonder how they deal with the back feeding issue. Is there something about the home wiring in those countries that prevents it? (or do they just not care and line workers know to check if a line is truly dead?)

Is this more of a battery cost issue - if you owned a battery that charged off the grid and discharged during blackout periods then that might just about cover you if you budget for the expected outage duration.... And assuming you can afford said battery in the first place.

> if you owned a battery that charged off the grid and discharged during blackout periods This wouldn't work. The reason isolated units can inject electricity back into the grid without issue is that they can observe frequency. If a blackout occurs, this information is gone. You need to perform a black start, which can't be done by isolated, uncoordinated equipments.

What you actually need is islanding equipment which discharges the battery for local use only, but cuts off (or islands you from) your main incoming power connection.

Many of the PV systems you can buy from the big players (SolarEdge, Tesla and more) support this, often calling it "whole home backup".

Same principle as having a generator with an interlock.

In my jurisdiction, you don't need a permit if you're doing it yourself, and it's on your side of the panel.

So the plan I came up with is essentially the plan you have, but I connect my refrigerator to the battery by the panel rather than running an extension cord from my kitchen to the battery.

I disconnected the fridge and 2 other circuits from the panel, and terminated them with a nema 5-15p inlet receptacle like this: http://www.levitonproducts.com/catalog/model_5278-CWP.htm

I then put 4 solar panels on a 45 degree angle on the ground leaning against a south facing wall, anchored to the wall and ground.

The "solar generator" I used is this one: https://www.indiegogo.com/projects/apex-300#/

It's similar to the glamping batteries you refer to, but is more targeted to home backup / off-grid / RV use than glamping.

Earlier quoted context omitted.

Could you please explain the "socialist cultural rot" and the "eradicate cultures"? You might mean something totally sensible but this wording is quite triggering to me.

Everywhere socialist movements like the ANC take hold- there sets in a "im going to extract as much as i can from the state as he extracts from me - while giving him nothing" mindset. Its prevalent in the older generations in the eastern european block countries, china - its almost universal where the socialist experiment was run. The idealized society does not mesh and work with human nature at all, in fact it bring…

I am sure a capitalist system will NOT work great for a tribe of hunter gatherers!

The problem is not the socialist type of ideas, it is whom you are applying them to and at what point. The society must have certain complexity, capabilities and resources to be successful "socialist".

Going from feudalism to socialism was shown repeatedly not to work (ex: Russia, China). The countries that are currently more socialist and successful were not primarily feudal when they applied the socialist ideas. Also, there are huge differences in what is called "socialism"...

Even in the USA, capitalist came with "socialist ideas", like Henry Ford that said that one more free day will boost his overall sales, but the moment was right. I think he could not have done the same 100 years before.

Meanwhile, in third-world, overly bureaucratic Italy, one has to wait several months to get all the paperwork in order to take advantage of a solar installation. Self-deployed solutions are also limited to 800 watts, which is peanuts in today's world.

That is the case only if you want to give your surplus back to the grid. If you avoid that, you are only limited to a maximum power of 20kW of solar panels installed.

20kW seems to be ample for home usage. Half should be good enough.
