Tungsten is in inverter power supplies in other places outside of power supplies for welding. Inverters are very big, and tungsten has been used in them in many places including but not limited to almost all high quality amplification and large equipment including washing machines etc.

I understand that inverters are suddenly in vogue now and the the high end tech community is only familiar with the newest implementations in the highest end products in silicon valley, but many household products use inverters, with very standard designs of which tungsten is a apart of them, and most high quality amps use tungsten. I'm sorry you are denying reality.

You can go buy tungsten amplifiers online right now, the highest quality ones use tungsten...

or in my case in the one I designed and build from scratch this year I used vacuum tubes with tungsten filaments. Tungsten filaments reduce thermal distortion and allow a highly increased level of harmonic filtering.

Why? because transistors have a hard cut off for filtering sound, and actually most audiophiles prefer still to go back to old school designs utilizing vacuum tubes because there is no step filtering, and for people who really thrive in developing in ambient space or amplification quality for acoustics in buildings for high quality production, tungsten is still highly regarded...

in regards to the wind turbines, I believe you. I was not sure, and I've never actually seen or touched built, or designed a doubly fed induction motor, but I believe you, and I'm not arguing with you there, but I wanted to clairfy, because alot of cars, and other things that are "sustainable" are actually not when you do the research, so I always try to clarify instead of jumping to conclusions.

I know Tesla is RE free, but again, they are an exception to the rule versus the more affordable and abundant implementation like the chevy volt, nissan leaf or the prius.

In regards to lithography and PV module manufactoring, do you have any other proof than just the claim that it is nonsense?

For the only two years I stepped outside of working in Power Engineering specifically, I worked in manufactoring semiconductor chips doing chemical deposition in expitaxial growth in Diffusion.

I didn't really know anything about the industry going in, and I was lucky to be working on a team with 7 Phds from MIT who worked at AMD for 7 years, designing 14nm and 10nm transistors, and working on troubleshooting nonidealities that occurred in the line as they tested those out on the floor for the first time. So I was kind of the first person looking at results on the floor.

Regardless that to provide context that Lithography, Diffusion (fvx, ion implantation, RTA, LSA, EPI) is downstream in the development process from Lithography but all of the processes are interrelated, and a mistake upstream won't often be found in metrology until it reaches a downstream department, downstream in relation to the linear modules building out different steps of a semiconductor chip.

We worked with multiple customers, manufactoring designs including bitcoin mining chips, smart phones, game consoles, none of which I can name specific brands due to NDAs which I respect even though I don't work there as thats part of the NDA. As a startup, the company was always looking for new customers other groups were not looking for, and we prototypes all kinds of interesting products that otherwise would not be able to break a monopolized high priced manufactoring barrier for nm level chip production like samsung, intel, amd etc.

While I know nothing in comparison with the brilliant people I had the opportunity to work with, and did not want to work in manufactoring, and left to go back to Electric Power Engineering, I did learn alot about potential customers for solar pv for the specific purposes of litho, and it's definitely not nonsense.

If you have some alternative source of information that invalidates my existence for two years where I worked on this, please provide and I'm open to factual information, but its not productive to completely write someones comment off as nonsense just because you are not familiar with more recent developments in the crossover between industries by rapidly prototyping development before going public.

CRASH COURSE
In regards to taking a crash course in renewable energy. I havn't taken a crash course, but I do have a Bachelors Degree in Electrical Engineering, with a concentration in Electrical Power and a Masters Degree specializing in Electric Power taking graduate classes such as

Power Generation and Control

Semiconductor Power Electronics

Advanced Semiconductor Power Electronics

Power System Analysis

Electrical High Power Engineering Lab

Electricity Economics

Electric Machinery

and am published in IEEE for large scale power flow networking.

and worked at the second company in the world to exclusively specialize in substation integration and construction of solar, geothermal and wind farms. in 2012, the startup I worked for, which at the time I was the 20th person to join and the 10th Electrical Engineer, took claim to having designed and constructed over 20% of all renewable energy farms in the United States at the time. We got bought out by a multibillion dollar company and now I work for another startup doing software design for the smart grid for large scale power flow.

I've designed and been out with my team construction team to oversee the construction of geothermal substations and solar farms, but never a wind farm, and I didn't know about the lamination in wind tubrines, which is why I asked, because in the real world, you can't just claim to know stuff you don't know, because when you do that, people can get hurt and killed when working with high power kv equipment, so I don't know about other industries, but in my industry, when we fire up a 345kv transformer and test out breakers for the first time, we don't claim to know stuff we don't know. So when I ask a question, I'm not trying to test your authority on the topic, I'm asking you to know the facts, because the facts are important in the real world...

Having been on site to construct 4 renewable energy farms and overall 39 substations in 5 different states for upgrades and other work, including replacing rare earth magnets in generators that took 8 months to build and replace due to price, processing and international importation of goods, and been in places including hydro pumping equipment stored inside mountains underground that you have to take an elevator 10 floors down to get to, I can tell you rare earth metals are alive and well all over the power grid, and their rarity is relative to the production economy, and not the chemistry table.

but please...tell me more about how I'm full of complete nonsense....
