    Those questions don't allow for the possibility of installing louder exhausts for non-psychoanalyzable reasons... There are also degrees of loudness. I put a slightly louder exhaus…

    Thanks, that's a great suggestion. Looks like I can also use QEMU to also trace MMIO. I appreciate the advice!

    This would be fantastic. I'm trying to write an audio driver for my HT|Omega eClaro PCIe soundcard for Linux by leveraging kernel modules for cards with a similar BOM. It is mostly…

    The PE6000 and the LM6000 are two shaft machines, where there is a low speed shaft on which sits the low pressure compressor and low pressure turbine (the hot and cold ends), and a…

    The PE6000 is closer to a GE LM6000 rather than an LM2500. https://www.gevernova.com/gas-power/products/gas-turbines/lm... The LM6000 and its variants have been in operation since …

    People tend to use the inertia H constant (MW*s/MVA) when it comes to describing the amount of inertia that grid forming inverters and batteries can provide. Sometimes the units ar…

    Would you mind sharing any pictures or video about the mower? I converted my push reel to electric without a kit, and have been considering putting separate high torque, low speed …

    GE Hitachi Nuclear is hiring people for across the nuclear island, steam island, and other plant components for their SMR design. It is a pretty exciting time for that division, so…

    Gas plants can change load in seconds by increasing or decreasing fuel flow. You can consider the generators as operating at the local grid frequency, and power being the product o…

    There's no mention of the actual electrical architecture. In the rendering, I only see modules and no DC/DC converters or inverters separate from the modules. Some of the competiti…

    I design control systems for grid scale battery systems that can operate as standalone power plants, or as hybrid power plants with solar, wind, or gas turbines. Batteries essentia…

    Does this impact Google apps (or whatever their grandfathered personal email hosting/google drive is called now)? I hope it's just the registration component, but I think I should …

    Turns out it was STS120, launching the Harmony module on Oct. 23, 2007. I was working at a facility where we tested gas turbines and spent a good amount of time studying combustion…

    Rocket launches feel the same way. I got to see STS121 launch from the VIP area at Kennedy Space Center a couple of years back, and it felt like a continuous pressure wave pounding…

    I agree with this. You also don't know the exact mix of sources generating the particular amount of power consumed by your data centers instantaneously. Since each generation sourc…
