    Only if a good amount of folks do what you teach, just imagine how many millionaires we already have or will have in the future. I have been looking at similar opportunities. As Warren Buffet noted, he has witnessed this occur frequently. Never did my husband and I make more money than others in the middle class. With a $250k stock portfolio, we intend to retire at age 58. Never have we ever sold even one share of stock...

      I already own shares of Tattooed Chefs and Kairos Minerals, and I'll buy some Corsair as well. Sure, I don't mind having these equities sit around for a few years, but I'd also like to appreciate short-term profitable investments that could, say, turn $50K into $200K.

      I've worked with a few different financial advisors, but I ultimately chose ROCH DUNGCA-SCHREIBER* because she seems to be very thorough and knowledgeable about the financial market. I have made more profits with her guidance than I ever did when I invested on my own using RUclips.

    I see this video with errors and omissions. I am a retired steel mill supervisor who worked at the blast furnaces and coke plants. First, the amount of coke used per ton of steel is not 770 kg. It is much less like around 300 kg and less. Second, her pronunciation of the types of coal is completely wrong. Third, there is no mention of by-products that come from coked coal. The coked coal (coke) goes to the blast furnace and is used as fuel for smelting iron ore into liquid iron. The impurities she mentions are not impurities that are thrown away as she implies. These impurities are by-products that are useful to mankind. These by-products from coking coal are tar for making shingles for roofs and repairing roofs. Another is asphalt for constructing and repairing roads. Coal tar is also used as a raw material for making some plastics. Ammonia is sent to chemical plants as a raw material to make cleaning supplies and other useful chemicals. Also, ammonia sulfate is made in a coke plant that is a very valuable fertilizer. Another use for coke by-products is a fuel gas for firing boilers and heating homes. Lastly, light oils for industrial applications are benzene, toluene, and xylene. Coke is a needed material for years to come because not all grades of steel can be made by electric arc furnaces. Some complicated grades of steel are needed in autos and trucks and blast furnaces are the only way to make these steels.

    Green steel will be expensive expect prices of 2100 dollars a tonne and green hydrogen is energy thirsty. You need 50MW of electricity to produce one tonne of hydrogen and oxygen and heavy water as byproducts. Even so you still need 150kg of coke to fuse the impurities with limestone as a flux . The main goal is to reduce electricity from 50MW to 42MW so alot of R&D is needed.

    How are we going to produce our steel after the green movement shuts down all of our coal mines. A real answer please.

      There's an ArcelorMittal plant in Hamburg, Germany. This plant produces steel with natural gas instead of coal since the 70ies, and they are planning to use 100% hydrogen in the near future. And it's Midrex, a US company, that built the original plant and is now designing a new industrial-scale demonstration plant for "green" steel production. So the technology exists, you have it right there in the US. But the plant will be built in Germany, because - perhaps influenced by the 'green movement' - the German government is willing to spend money to push the development of new technologies instead of subsidizing coal mines that damage the climate.

      Ah yes, the all powerful "green movement" will shut down all of the coal mines.
      I wish I could live in your fantasy world.
