  • I don’t know if this is the full explanation, but the article does touch on how the LPM can be tweaked to match physical tests:

    The trick is to incorporate experimental measurements to fine-tune the model. If a physics simulation doesn’t agree exactly with experimental data, it is often difficult to figure out why and tweak the model until they agree. With AI, incorporating a few experimental examples into the training process is a lot more straightforward, and it’s not necessary to understand where exactly the model went wrong.














  • First of all, fuck capitalism. Its the origin of this problem.

    Second of all, until we can abolish capitalism, it will remain the case that labor is treated a commodity and wages are therefore subject to supply and demand.

    Third, most jobs in USA pay sub-poverty wages. Its wage slavery. Salaries need to increase.

    Therefore, policymakers looking out for the economic interests of the working class should do everything they can to create labor scarcity, including shutting down all immigration (decrease supply), abolition of taxation on small businesses (increase demand), and direct government subsidies for nationalized large businesses to achieve economies of scale in strategic sectors (increase demand).






  • Rods from God deliver the energy of about 12 tons of TNT.

    For comparison:

    The British used 12 ton “Tallboy” bombs, carried by Lancaster bombers, in WWII against submarine pens.

    The “Little Boy” nuke delivered the energy of 15,000 tons of TNT.

    Some modern ICBMs carry 10 warheads, each of which delivers the energy of 475,000 tons of TNT.

    One benefit of dropping a tungsten telephone pole from orbit is that there’s no good way to stop it, because its just a chunk of metal moving very fast. Hitting it with a missile might scratch the paint, but won’t significantly alter its course.

    The main drawback is the expense of getting them into orbit. Falcon 9 can lift 2 of them if the poles are cut in half to fit under the fairing, at a cost of about $70 million. That does not include rocket engines, fuel, and targeting computers needed to get those 2 tungsten rods out of space and onto target.











  • When people talk about “smart thermostats” in this context, they’re saying they want the utility company to be able to set the temperature in your house in exchange for pennies off your electric bill.

    By reducing the delta between peak and baseline energy demand, the utility can sell the power generating facilities that only run & earn income on the hottest/coldest days but which are a constant expense even when they’re not running (i.e. most of the time).

    The plan is to make poor people uncomfortable on the hottest and coldest days in order to lower everyone else’s electric bills.







  • The 97 per cent limit was chosen for a specific reason. During a demonstration, BYD chairman Wang Chuanfu explained that ending the charging process at 97 per cent is a deliberate energy-saving measure. The remaining three per cent is reserved for regenerative braking, which helps reduce the vehicle’s overall energy consumption.

    There are some good reasons for designing the system that way, but its irksome that its framed as an energy saving measure. The energy required to accelerate a vehicle is always greater than the energy that can be recovered through regenerative braking due to thermal and mechanical losses. Therefore, if you start driving on a flat road, you’ll create sufficient space in the battery as soon as you move.

    That last 3% charges slower, and BYD gains a competitive advantage by moving the goalposts to say that 97% counts as “full” because reasons.

    It does mean that a car charged on top of a mountain can still do one pedal driving on the way down. Consistency of how the car responds to pedal inputs is a safety feature.
