It is an emergency lasting at least 8-10 months starting now so as to not deplete the reserves. I don't think the turbines can last that long without regular heavy maintenance. Also, I highly doubt some of these can run on crude oil. Before this claim the only type of device capable of such fuel ranges I knew of is the main battle tank. It makes more sense to me that a tank is designed for versatility, and a gas turbine for efficiency on a single precise fuel. What's exactly the catch here? I'd like a source on these claims

Note that gas turbines are very flexible with fuels because it's a continuous combustion process and done at very high temperatures. That means you don't care about flamefronts, knocking, octane figures, etc. All that matters is that whatever you burn ends up hotter that when it started, which is kinda the definition of a fuel. Also, no expensive high precision parts of the engine touch the flame - all combustion is over by the time you get to the turbine blades (which are film cooled anyway, so even the combustion gases don't touch the blades)

  TIL. Well, color me surprised. I even found a source mentioning crude oil: > Oils: Includes crudes and other refined residuals that are heated to acceptable levels to enable the needed viscosity for gas turbine combustion. https://www.ge.com/content/dam/gepower-new/global/en_US/downloads/gas-new-site/resources/reference/ger-4601b-addressing-gas-turbine-fuel-flexibility-version-b.pdf https://www.ge.com/content/dam/gepower-new/global/en_US/down...

    They are selling you a turbine. Of course they’ll make coffee for you if you wish.
