      Wouldn't 'Let's go get smarter together' or 'today' or something of the likes be a bit more appropriate, due to it being an instance of becoming smarter rather than a culmination of instances at once? I feel like 'let's go get smarter every day' for one specific instance of becoming smarter is a bit misplaced and misnomed in comparison, and leads to a moment of awkwardness in my mind; as if it's advice, rather than a welcoming invitation. Maybe it's a solo perception, but here's to hoping this mention of insight can provide some benefit. Cheers, Destin.

They talked about it openly on season 2 of mail bag. OBVIOUSLY you arent going to waste a perfectly good source of compressed hydrogen and just dump all of it back in the ocean.

    I was surprised when the guy said about the solidified ash left behind "they call them clinkers, I don't know why" it's because sometimes when conditions are right in a wood stove some of the ash almost glassifies and the chunks clink in the bucket when you clean out the ash. Really cool, I've heard about oxygen candles but never saw one in action.

  36. Fullgrizzly94
    4 jam yang lalu

    If I had to guess, the pre-heater before the MEA boiler is to heat the MEA faster so less energy can be used in the boiler section, which might also save time. Because the liquid is moving through the heated pipe section, they can make use of convection and not have to wait on the convection flow within the tank.

    It's called a clinker because The word was passed on from UK submariners - original clinker bricks are bricks of clay made kinda shiny brittle and/or vitrified during a firing that exposes the brick to very excessive heat. Real/actual building clinkers are/were commonly used in the UK for building homes, to add historic looking appeal. People still use them to build homes that they want that certain aesthetic - it (more) often does from people using reclaimed clinkers now, as they aren't made very often anymore..... Phew, that's probably a bit too much info. But there you go, in short: a clinker is just a brick exposed to very very high heat.

    So why don't they use a couple plants and shine some light on them? They tried it in a russian closed atmospherics experiment and the problem was the plants grew and quickly produced too much O2, causing a fire hazard, so they had to start burning plants to remove some of the excess O2. But with some good controls and experienced operators it should be perfectly feasible.

    i noticed you seemed a bit confused as to why the mea system used a preheater. I am fairly certain it has to do with gas retention. Hotter liquids retain less gasses than cooler ones.

    I think the "preheating function" is just a heat exchanger with the output of the boiler stripper. Take the energy out of the lean MEA to better condense it and put in the rich MEA that you're about to boil. Save some time, save some energy loss.
