@NateSilver538 I’m really enjoying On The Edge. I caught an old episode of the west wing last night and this clip made me think of your book: Bruno is a Riverian->

@JonahDispatch I’m a big fan of yours (and the dispatch) , but what is trite about it? It seems mostly correct
English

I get why lefties are gushing over this, it’s well delivered and politically smart because it tells the left what it desperately wants to hear. It’s mostly a trite fan service answer. And i’m hardly a Vance booster.
Meanwhile, I’d definitely read a piece on how Vance is the right’s version of Pete Buttigieg or vice versa.

Wow. If you are to watch one video this morning, watch this. Pete Buttigieg perfectly explains why Billionaires in Silicon Valley now support Trump and why J.D. Vance has flip flopped to liking Trump.

@CaHSRA Did they consider not quitting after they built that part, and instead continuing to make it longer in one or both directions?

@emollick I’m sure this is covered in your book (so apologies) but what about management writing is also a very important tool for thinking - I’m often not sure what I think we should do before I write a business memo on the topic. If I outsource the memo > I don’t really understand it

@michael_nielsen What about cooling capacity. Doesn’t that become the primary constraint at some point?
English

Interesting to think about the scale of data centers. A H100 at peak is ~700W, and typical utilization in a heavily-used cluster might be ~500W. So a cluster of 100,000 H100's is ~10^2 MW
By comparison: Hoover Dam is~2000 MW and the Three Gorges Dam is 10x again
So there's headroom for 100x the power for large data centers. Much more, though, and you are building power stations at a new scale

@asymmetricinfo It’s a good invention! Just saying the poison isn’t going down easy.
English

@asymmetricinfo Maybe, but logistics of that are still hard- you only really care about eliminating weeds during a small part of the year when they can choke off crop growth. And weeds grow fast and can do a lot of damage if they aren’t handled.
English

I love this and the weed laser and every other solution that is not “poison” but do wonder how it compares to the poison, cost wise. Because if the poison is cheaper, that’s what farmers are likely to use.

Meet EcoBot the professional weeder. The Machine Learning, Solar powered apparatus that can run for the entire day pulling weeds. Replaces expensive in every possible way, herbicides.

@bendreyfuss You don’t meet the red wine vinegar and the lemon juice. Pick an acid!

@ChrisHerrington Gonna catch it VOD but doesn’t seem worth a trip to the theater

@Lucas_Shaw You think this would have any impact on the strike negotiation dynamics?

@WynBellhouse This will be their pump up video before they launch the attack to kill us all!

@SonnyBunch Also every new bar that Taffer makes them create is such a train wreck immediately

@bendreyfuss @janecoaston @neontaster @charlescwcooke “A travel expert answers” lol - not sure we need an expert for this one.

@janecoaston @neontaster @charlescwcooke Yes but also, I don’t want to sit next to their kids! Everyone wins with a switch

@theissler @BrianGitt Isn’t your second point a mark against batteries rather than for them?
English

The statement is not entirely correct for several reasons.
Firstly, as you mentioned, it doesn't consider the efficiency of the two systems. Combustion engines, as typically used in most jets, generally have efficiencies of 30% to 40%, meaning most of the energy in the fuel is converted to heat rather than propelling the aircraft. In contrast, electric motors often have efficiencies of over 90%. Very important!
Secondly, the statement compares the mass of the fuel to the mass of the batteries, which isn't entirely fair. An important part of an aircraft's weight is the fuel, which is consumed and therefore gradually makes the aircraft lighter during flight. A battery, on the other hand, weighs the same no matter how discharged it is.
Thirdly, advancements in battery technology could lead to future batteries weighing significantly less or storing more energy than current lithium-ion batteries. So, it's not correct to say electric planes "won't fly," based on the current technology.
Finally, the statement doesn't account for the fact that electric aircraft might use entirely different design approaches, such as distributed propulsion systems, which could further improve efficiency.
