    Flight documents show MH370 was ‘buried in an ocean trench by pilot’, says Boeing expert

    You do realize that ALMOST ALL ATC radar input is from transponders, not radar reflections. I am not an expert, but I doubt non-military radar can get a skin-reflection at 100 miles, much less 1000 miles. Satellites would seem to have a better chance since the full wing area is available from...

    Parker HT-1000 Hydraulic Fluid

    The Parker literature specifies their HT-1000 fluid. They have a Shell alternate. They specify changing their HT-1000 every 1000 hours, the Shell every 250 hours.

    Used Toyota Mirais, 90% depreciation (Hydrogen Fuel Cell Vehicle), ICE / BEV conversion candidate?

    Citation? Are you sure those conversions aren't to CNG or LNG? Those are what I have seen locally.

    Safety Seal Tire Plugs

    Industrial hydraulics guy here, and "rubber" sealing items. O-rings and accumulator bladders stored for long terms are in black plastic sealed bags. Light and ozone are the concerns.

    Under the Radar, "GM snatches Key Tesla gigacasting supplier"

    Bondo is for the finish; duct tape or JB Weld for the structural repairs

    I never knew EV charging worked this way;

    What make/model EVSE do you use? I've personally seen one with the 10A choice. Can (is EVSE capable) you use other values between 10 and 16? I've seen advertised DIP switch selectable and WiFi control that APPEARED to allow any current between 12 and 80.

    I never knew EV charging worked this way;

    NOTE: I'M NOT AN EXPERT ON THE NEC, just have electrician friends and we talk about these things. NEC says something close to "a continuous load is limited to 80% of circuit ampacity". 80% of 15 is 12, and of 20 is 16, as you said. AFAIK, the EVSE is the only common continuous load in...

    Hitachi Zinc free hydraulic oil

    I understand. I ignorantly didn't see the Alaska. I'm one of the old-timers who are not in love with High Viscosity Index fluids, but you are in a location where one is appropriate. The coolant thermostat will control engine temperature but not hydraulic oil temperature. With "normal" ISO32...

    Hitachi Zinc free hydraulic oil

    @nate379 says "We normally use 15, 22 or 32 in equipment here." @MolaKule is the expert here, but at your ambient temperatures, I'd be very wary of an ISO22 fluid, and plum scared of an ISO15 fluid. What viscosity does the machine manufacturer (Hitachi?) recommend?

    CHECK YOUR TIRE PRESSURE!

    It makes the nitrogen supplier money. What's important is that the compressed gas is dry. Our air is 99% nitrogen and oxygen; each obey the same gas law within experimental error.

    I never knew EV charging worked this way;

    Because there is no charger in the EVSE (Level 1 and 2 at least). It tells the vehicle its capability and the vehicle charger draws up to that amount. I'm unaware of any single-phase Level 3 EVSE. Most (I don't have support for this, just my understanding) use 480/3/60 in the USA and 400/3/50 in...

    I never knew EV charging worked this way;

    According to CNN, "When you first plug in an electric car, a lot of information passes back-and-forth between the vehicle and the charger before any electricity starts moving, said Nathan Wang, project manager at UL Solutions Advanced Electric Vehicles Charging Lab. For one thing, the vehicle...

    Dumb trailer tire question

    I believe that you will find them to have very close to the same revolutions/mile. 2WD are about 30.5" diameter, 4WD are about 31.5" OD.

    TPMS battery life?

    My 2008 F-150 still has the originals. I don't know if there is any dashboard notification for non-working sensors.
