    Why are the transistors so splayed? as if it could take larger units.

    Perhaps no innovations are needed.

    In theory running a chip at half speed allows for one eighth power consumption, i.e. a 400% improvement in efficiency.

    P ~ V^2 f
    f ~ V

    The first is just...

    Fusion could take us into the far future... but will the moderators let us continue?

    Nuclear fusion based on helium-3 mined from the moon seems a distinct possibility.

    It's a cool digression, but I don't want to get into an argument. However



    it could be argued that last few percent may not save much but could lead to supplies that need no fan.

    Absolutely, and heat trapped by greenhouse gasses is the dominant factor.

    True, the power station is as much a heat engine as a car engine, but it has the advantage of being an external combustion engine and so much more flexible on fuel.

    The ICE still costs about 4...

    Interestingly ball bearings tend to be nosier than sleeve bearings so it may have been just fine; but I would also have replaced it.

    Efficiency
    Stability
    Resilience


    are all very important, but for me

    One must be careful with efficiency; one can extract energy from the 25C temperature difference between the surface of the ocean and 300m deep, with a theoretical maximum efficiency of 7% (so much...

    I'm the other way around, I'd hate to risk shorting stuff with conducting grease; bulb grease is actually a dielectric (silicone grease).

    They save a few pennies and take a big risk. For now I have tightened the connectors and added a little silicone oil to discourage further oxidation.

    Electrical connections

    When will someone figure out a good electrical connection, not just for power supplies but in general. My microwave is full of burnt spade connectors and it comes back to life if I tighten them so...

    I hope the future is not one of overwhelming spam.

    Even so, it did make me think of a way to redesign connectors... with internal equalizer plates.

    Isn't a better solution to join the pins inside the 6 pin connector; then one can still have just 4 wires if one wants but all 6 pins will share the load. This might also help if the wires are...

    Maybe by mining the moon for helium-3 to run nuclear fusion reactors.

    see "Maximum amps for power transmission"

    I think PC power supplies run a lot higher.

    My concern is GPUs; I see them going in the opposite direction.

    One thing that gets to me is all the energy expended on mining; makes my 2W wasted seem trivial.
