I hate rocket on my pizza!

Seems like their homemade ones were working pretty well at a fraction of the cost.

Any consumer electronics is difficult to get into. Certainly the auto industry. Railroads. It’s difficult to start an ISP, even a non profit one. I think the list goes on.

Ok. Same reason firefighters are not supposed to let their kids wear their helmet while selling lemonade. They are supposed to be impartial.

For the same reason police shouldn’t be allowed to participate in white power marches in their uniforms. They are supposed to be neutral.

It’s pretty much the only place left to operate. Protectionism has stopped innovation everywhere else.

You will need to watch the next one to see how a transistor works. It to, is very simple and very clever. I do know how these guys figured it out.

If you have questions I am very happy to try and help. Someone did it for me decades ago.

I had to find this. This explains on an atomic level how semiconductors work. For me this was important for me to gain an intrinsic understanding of what is going on in computers.

It is simple and fascinating and brilliantly clever.

I think you’re asking all the right questions and I think knowledge of these things makes you much more capable.

I think a good answer that you will understand is too long for this format. I gave a brief answer but then I went off looking for better information. Sorry to offend you.

I think this course from Ben eater on how he built his own CPU from logic gates might explain a lot.

I think it also covers how transistors work which is fundamental to how gates work.

1. Flashing code to a chip doesn’t really involve light.

2. you used switches on the front panel to load code into the computer by setting individual bits high or low. Typically you toggled in the bootstrap loader, which was a program that read a sequence of number directly into a spot in memory. The first program loaded by the bootstrap loader was usually the absolute loader. This was another program that loaded data from some peripheral, similar to the bootstrap loader, but it could do error checking and also load to non- sequential locations.

3-the Internet isn’t light. It’s electricity. On fiber the bits may be temporarily encoded as light, but overall it is electric.

4- You can understand it all if you want. It depends on the depth to which you want to understand it. You can understand a mouse has a plastic shell. You need some organic chemistry and chemical engineering to understand how to design plastic.

5- I recommend Ben Eaters YouTube channel to get a good overview of the basics.

Nothing really beyond Google. It returns some good info from nrel which I would trust.

I would install solar for the loads I wanted to support. I think the panels are cheaper than the wire used to connect them together.

There was a YouTuber that used to do this but I can’t find him anymore. He had a shop in which he ran the power tools off 90vdc straight from the panels. He said when you were using the table saw and the sun went behind a cloud you would have to slow down a little bit. He ran his refrigerator off of a separate panel and it only ran during the day.

He had a nickel iron battery for things like lights at night.

Microinverters can make this pretty easy if you are going to be grid tied. They are worth learning about.

If you are going to use batteries and not be grid tied you might look into microgrids or maybe community grids.

If it were me and I understand correctly I would probably not tie the systems together.

I would only power it when there is a car on top of it. That was done a hundred years ago. Now it is much easier. It just takes an IGBT per section. Seems pretty easy.

Magnetic Resonate wireless chargers are about 90% efficient but it seems that is a lot more complicated and expensive. Still this seems like an huge improvement over those charging stations.

I don’t see any reason to charge from the top of the vehicle no matter what method you use.

How does it increase complexity? It seems like it would be simpler than this mechanised charging system. A third rail wouldn’t prevent the tracks from being shallow and simple.

Yeah. I get that. I think it is an excellent design.

By adding a third rail in acceleration and deceleration areas you would greatly increase electrical efficiency and reduce battery requirements. You wouldn’t waste power charging and discharging the batteries during deceleration and acceleration. Additionally, the battery would only need to be able to provide enough power to maintain the speed. This also reduces the weight of the vehicle.

I like this too. I think it could be improved with ground power or a switched third rail in the areas where it is accelerating and decelerating. It seems like overhead power is costly complicated in this age of cheap IGBTs.

Doesn’t seem to me to be an outrageous request. I would have put it in a baggie or Walmart bag and returned it to the store, but it looks like it was resolved pretty easily. The threat to run it on the counter seems unnecessarily Karen.

Why is that a weird take? Seems to me the price should be the price across the board.

Including a small compact neighborhood uranium mine.
