If you install a balcony solar system and it produces more energy than you are using at the time the energy you are putting back into the grid is counted as energy consumed and you end up being billed for it.
In what country is it legal to sell such balcony solar systems?
And what country has such odd meters that flow into the wrong direction makes it count the same as the right direction?

Sorry, that does not make any sense at all.

In general if solar panels are put on land, they are put so that agriculture is still possible. The simplest is gassing cattle. More complex is agrivoltaics, see for example: https://www.nature.com/article...
Of course there are exceptions. In the EU we had plans to reduce the amount of land used for agriculture. For some stupid reason, the EU demanded that such land that got repurposed can not secretly still be used for agriculture, so plenty of farmers put low mounted solar panels on it.
Some of them did that close to rail tracks, as there was a second pot of subsidies covering installations (of what ever) along rail tracks.
The very little win : win of that is, that usually the power gets feed directly into the rail overhead line. Note: German Railway has its own grid, with its own frequency.

Okay, then please make a list in your mind, what all has to be done to what kind of quality standard, when you install a 100MW solar plant.

Hint ... having 4 human mules carrying a $500 panel per piece around: is not the main factor of manual labour.

The robot can very well work on parking lots, and with minimal adaption on flat industrial roof tops.

Your parent is just a troll, with typical troll questions, to make him look interesting.

In my eyes he just looks dumb. He could visit the web site of the corporation producing the robot, and ask for a quote ...

Topics that do not have much to do with each other at the moment.

Zero crashes on my Macs since 10 years or more.
5 blue screens on my Windows 11 acer last 28months.
Minimum 10 times "windows discovered a problem, and needs to reboot now", often by two or even three reboots in a row.
Not even telling what the problem is ... might be ... could be.

How do you come to 10x when you have on one side zero crashes and on the other side 2 dozens, depending how you count ... well, I guess someone rounded zero up to 2, or something.

Well, when I read it was all pounds, in Europe, I wondered how much that is in kg. As I am lazy, I just divided by 2 ... but the result was a kind of odd number, so I lost a few bits of accuracy.

Then, considering that this is at the Swizz and German border, I wondered if they used forced workers, like the many refugees to get the container on the truck!

I am relieved to read, they used a crane!!

Now I only have to figure what exactly -half a thousand degrees Fahrenheit is. I guess I can google for an AI to find that out.

They created fusion.
At least they claim so.
It is clear from the article.

And they are not the only ones. We have plenty of definitely non scam fusion companies that do fusion.

The question is will it once be commercial viable.

NASA tested solar sails just recently: https://www.nasa.gov/smallspac...

Well, the JPL has the Vasimr drive, a plasma engine.
They are working to "upgrade" it into a fusion drive.

https://en.wikipedia.org/wiki/...

However regarding the upgrade to fusion they are pretty silent since a decade!!

Some key researchers founded their own company: Ad AStra.

The key researcher a female Ph. whose name I forgot, vanished from publications.

So no idea what is going on there. No idea actually if JPL is still involved.

Fact is they have a working - pretty nicely working - plasma engine. Since over 20 years. I guess there is again some big industry in the US who wants that project to fail. For what ever reason.

The magnetic field is not really a problem.

The people who did more math on it, I read around 2010 about some scientests/sf authors, figured the vacuum outside of solar systems symply is not dense enough in hydrogene.

It might - just slightly - be possible to have a drive based on fusion and hydrogen capture inside of a solar system. Question would be if that is practical or if it would not just make more sense, to have refueling based ice from comets etc.

While it is an enormous problem, possibly the most significant, we know how to shield against radiation, but it's going to take mass in the form of hydrogen-rich molecules like water or polyethylene (as examples). To solve that problem we are either going to have to make launches a lot cheaper, or figure out how to do it all in orbit.

It's at the edge of our technological capacity to produce such a spacecraft now, so the barrier is economic. That's a massive barrier, but in theory we definitely could, if we put a significant percentage of GDP of the wealthiest nations towards the project, produce a spacecraft that keep astronauts alive and relatively protected from ionizing radiation both on the journey and while on Mars.

As to your general assholery, I guess everyone has to have an outlet, though why Slashdot is a bit mysterious.

That globe had nothing to do with fusion ...

Have you ever heard a single person, including plumbing professionals, call them "copper-phosphorus pipes"?

No. Because that's not how the English language works. You're the one who is too lazy and ignorant to figure out how people actually communicate in society.

Hint: The systematization your mind wants to apply to everything is not absolute. You need to figure out when to relax the formal logic rules when they start to result in absurd outcomes.

I don't know if it's still strictly true, but they used to say that all of the antimatter that has ever been produced by humans has had enough combined energy to warm up a cup of coffee.
