Some have asked "John why are you so interested in the Boston bridge?" Here's why. I made my living working on the largest land based equipment in the world, avid boater my entire life and almost died when my boat lost power in the St Clair river/tanker bearing down on me. 🧵 When I'm told by certain individuals to "Stay in my lane" mining, to me that's an insult. Believe it or not I have many diverse interests that I have studied and experienced at great lengths. I am not a one dimensional person.

What is this? It's a schematic of an emergency steering system, as the name suggests, is a system that is used during the failure of the ship’s main steering system. Follow along and I will show you where I'm going with this. 🧵 Image Mining haul trucks have a steering safety system where If power is lost you must have a means of steering. This is done with a stored energy system by means of an accumulator.

Are batteries the future? A lot of people seem to think so, but are they? Let's put this argument to rest once and for all. What would it take to power the US for 24 hours (11.12 TWh)? In this thread I will discuss sodium, Li-ion and lead acid batteries. #GreenEnergy 🧵 Image If lithium were used for both EV and energy storage, reserves would not last long. But there’s a lot of sodium. A sodium battery is better than lithium as well because it is safer and keeps most of the charge when temperatures fall far below freezing.

Good Sunday Morning. Let me tell you a story about Canada's "free" health care system. This is my friend Mike with his band the Black Orchids. His son became very ill. They took him to different doctors trying to find out what was wrong. The doctors then referred him to .. 🧵 Image specialist for further testing. The problem was his son was getting sicker and it was going to take months for further testing because of the backlog of cases. Mike and his wife said enough is enough and crossed the border into Detroit. They found out in a week his son had cancer

If large power transformers are destroyed by a geomagnetic disturbance (GMD) electromagnetic pulse (EMP), cyber-attack, sabotage, severe weather, floods, or simply old age, parts or all of the electric grid could be down in a region for 6 months to 5 years. Image This is because the USA imports 85% of them (and all of the largest ones), there is competition with other nations for limited production and raw materials such as special grade electrical steel, a high cost ranging from $5 to $20 million dollars.

People can survive without gold, silver and platinum. But life as we know it would be impossible without salt. Salt is the only mineral that is not publicly traded which means one company can own it all. Control the salt, control the world. 🧵 Image Salt has more than 14,000 uses. The union of sodium and chlorine forms the molecule sodium chloride (NaCl). Salt which is essential to our survival.

A #GreenEnergy thread: How are EV batteries recycled?
Two ways, pyrometallurgy and hydrometallurgy. The more common is pyrometallurgy, in which recyclers first mechanically shred the cell and then burn it, leaving a charred mass of plastic, metals, and glues. Image At that point, they can use several methods to extract the metals, including further burning. “Pyromet is essentially treating the battery as if it were an ore” straight from a mine. Hydrometallurgy, in contrast, involves dunking battery materials in pools of acid

If you want to learn more about mining I can teach you more about mining. Hell I can teach you so much about mining all you will need is a helmet, cap light, a pair of boots, lunch bucket and you will be ready for your first day of on the job training. UG or OP. Image The mining and metals sector is facing a crucial juncture with a shortage of skilled workers and retirees leaving the industry in droves. For instance, in May 2022, the US mining sector had 36,000 job vacancies, up from 27,000 the previous year.

800 sq. ft. of solar panels weigh 1 ton. 2.5 lbs per sq. ft. 40-340 watt panels is what's needed to power a typical family home. This depends on sun zone, amount of snow cover etc. Approx. cost $10,000 dollars for panels. 10K divided by 20 yrs.=$500 per yr. #GreenEnergy 🧵 There is approx. 140 million housing units in the United States. 112000000000 sq. ft. of solar panels would be needed to power just the homes excluding all industry. 4017.44 sq. miles of panels. How much mining/manufacturing do we have to do to make that amount of solar panels?

Mining requires a lot of explosives. 300 holes, each containing 1 ton of anfo. The toxic dust from the explosion would settle miles away. This is just another aspect of what it takes to make #GreenEnergy But they wont talk about that. Replacing hydrocarbons with green machines under current plans, never mind aspirations for far greater expansion, will vastly increase the mining of various critical minerals around the world.

Solar Panels: silicon producers use “charcoal plantations,” but they only supply a fraction of the current demand of carbon for silicon production. The rest of the carbon supply come's from imported coal or coke, or the cutting and burning of “virgin” rainforest. #GreenEnergy MG-Si is the result of purifying silicon using heat and reducing agent. The silicon may be 99% purse. Additional processing is completed until ultrapure electronic grade silicon (EG-Si) is obtained. For for one ton (t) MG-Si (Globe) it requires 2.4 Tons of woodchips.

Something the #GreenEnergy advocates never want to talk about is the environmental damage so called "renewables" do to the planet. I mean who cares about a vast man-made lake of poison in northern China, as long as it's not in my backyard. Right? 🧵 Much of China’s green energy boom was supported by a phenomenal growth in coal consumption which rose from 300 million tons annually in 1970 to 4.3 billion tons last year.

Welcome to the reality of mining underground. Could you do it? We used to joke, if there was a massive cave in, our families would save thousands in funeral costs. Not all underground mines are like this of course. 100s of pieces of equipment. The equipment has to be taken a part/cut up and lowered down the shaft and reassembled.
