I think a reasonable summary of the study referenced is that: "AI creates the perception of productivity enhancements far beyond the reality." Even within the study, there were some participants who saw mild improvements to produc

There were vehicle sourcing credits in the Inflation Reduction Act, which are granted per kWh of battery with sufficient domestic mineral content. Was $4,000/vehicle if I recall.

It’s a bad thing if it increases China’s confidence that it can win. Wars are often launched as soon as one side thinks it has a winning strategy that might slip away over time.

In most modern cars, there is a pressure booster in the power brake system, enabling braking force that can overcome the engine’s horsepower and quickly stop the car. But they are designed to continually maintain the braking force for a lim

I dunno. Honda doesn’t offer an electric CR-V, but they’re coming out with the Prologue, which is slightly cheaper than the comparable Passport. Passport: $43k Prologue: $48k - $7.5k tax credit.

The treasury would auction off securities—probably short term bills—in excess of the debt ceiling. I am confident that this auction would succeed, in that dealers would be happy to bid, possibly at high yield. The settlement process followi

The standard works on the other side as well. A Toyota with a NACS plug can charge on the supercharger network, but also other networks that are also adopting the NACS standard. A non-Tesla car that charges on a non-Tesla network doesn’t

Apparently he has attempted this before, only to require coast guard rescue—exactly as you suggested.

The single most important assumption in this paper is that energy consumption will increase by 2% per year. This kind of exponential growth leads to outlandish estimates for the amount of tidal energy that society will demand. Energy consum

There’s no reason to think that’s a permanent state of affairs though. Stellantis claims to have better margins than Tesla. Tesla sells a large portion of vehicles in China where the margins are tiny compared to those in the US market. h

The US installed 11.8GW solar last year. That is 453MW/every 2 weeks. :-) Yes, that’s nameplate capacity, so you can’t count on solar to delivery the power to get us over the line by itself. But we are nearly on track to the net zero g

I saw a Wi-Fi enabled lightbulb today. I cannot think what the use case is for such a device.

Was recently in a fairly new construction house in a very cold climate state that did not have a full basement below the frost line. There was a partial 8’x8’ corner that sunk down to where the water line came in, but the rest of the footpr

Are the middle and rear seats in the ID Buzz storable or removable? That was the only thing I remember.

Minivan seems like a great form factor for an EV. Unfortunately, the small number of companies that still make minivans are also the companies that are slowest to adopt EVs.

This is not the way I would do stock valuation. PE is the ratio of future earnings will all its growth to current earnings, discounted. In the future, some of that growth will be in the past, and the PE will be expected to come down. This b

Exactly. As an example, a typical 30-year fixed will be halfway paid off after 15 years, and so is about half as sensitive to interest rates as a 30-year interest-only. This should not be a surprise to the management of First Republic.

It was mainly just the mortgages. The quirk is that they marketed to extremely high-net worth homeowners—I think this is the penthouse condo crowd. In order to attract them, they offered 3% interest-only loans. Without principal pay down, t

Primary energy infrastructure planning takes place at a 20-30 year timeframe. GDP for 25 years is nearly $600 trillion USD, so the Master Plan is approximately 1-2% of available resources.

I assumed Tesla was at 300, which is pretty close. This might not be the tech for consumer cars though, but one thing I have seen is the enormous proliferation of applications for Li batteries as the costs have come down, and these will cer

The stats are not crazy for an air battery. But the catch is two-fold. First, are they weighing the battery before or after discharging? Oxidizing will change the weight significantly. The most honest result would be the average weight duri

Solar cells generate DC, but this is converted to AC with power electronics: the inverter is the main one. These are all just very high wattage semiconductors, but like all semiconductors, they can be destroyed by a transient event like a l

I’m just going to talk about fixed-rate US agencies. Treasuries are option-free, while fixed rate mortgages include a prepayment option. Also, these mortgages have a strong implicit backing of the US Government, so there is no default risk.

Not in this case: this is a tender offer, and what you're describing is a merger. Which might actually make sense, but it would be something that goes through the TSLA board, and can't be done unilaterally by Musk. Of course, he m

The most obvious use for excess power is surely storing it. In a battery, a flywheel, a gravity storage system, compressed gas—hugely economical.
