Every time I head anti-electrification arguments around EVs, heat pumps, etc. it's usually a complaint about grid capacity. I always shake my head, because building more power line…

I find this passage quite amusing: "Schöfbänker has also cross-haired with his equipment the "KH-11 Kennen" electro-optical satellites that were first introduced in 1976. "They are…

Pretty much every car with frameless windows works the same way. The window rolls down a little bit when you open the door to clear the trim. Mini, Audi, Mercedes, Corvette, and so…

The craziest thing is that that single external display can be up to 6k/60hz! Surely for those 21.2 million pixels you could run 2 4k displays at 8.2 million pixels each.

You get back ports, but those base model M3 MBPs only support a single external display. You get HDMI and 3 40gbps thunderbolt ports, but can only use one of them at a time for scr…

Agriculture is currently massively carbon intensive and is one of the hardest modern technologies to decarbonize. It relies on fertilizer production that is currently completely re…

If I recall correctly, the prius ICE and EV systems are totally isolated and only connected by the road in between the front and rear tires. The ICE runs the front tires and the EV…

A lot of those sensors average the reading over quite some time to avoid false positives. It's possible that the last few miles of road have just enough average slope or contain ju…

Read up on the upcoming FAA Remote ID regulations. They were scheduled to go online last Saturday, but were postponed 6 months. They would effectively make it illegal to fly at any…

Wing/plane drones are substantially quieter than quadcopter drones. I'm out flying RC with folks all the time and it's genuinely hard to hear an RC plane from more than 100 feet aw…

The bigger benefit of all of that bandwidth is going to be multiple users. If you work from home and have a big family, or just live with a few roommates you're going to be seeing …

Yeah, I think that consensus is part of the reason integrated cables took off in the USA. I think the biggest actual contributor was garage parking. Most drivers in the USA are par…

Even just having the gas car "city" and "highway" ranges would be a huge step up! Most EVs get much higher than their rated range in the city and lower on the highway, but most dri…

In the Type 2 spec there is an additional resistor on the control pins of the cord that communicate the current capacity of the cord to the car. That, along with the signaled capac…

The mode they're asking Tesla to remove isn't included in production cars. It's a development flag found by an outside hacker. This is giving me bad flashbacks to the Grand Theft A…

A changing course is one of the biggest impacts of flying outside. You have the wind directly acting on your drone, and you have the wind acting on the gates and flags. Flags will …

Gas pumps are larger transactions, so the credit card fees are less of a hit for the business. A level 2 AC charger is about $1 per hour of electricity, so you're taking huge credi…

The main limit is minimum transaction fees. A gas station is usually at least a $20 transaction. Since most level 2 charges are about $1 of electricity per hour, you're paying mass…

The biggest difference in the US is the integrated cord. It's about half the total cost and the primary wear item. If we had a spec similar to the UK where the charger had a female…

The plug can handle similar cycles under the spec, but a lot of residential plugs are not. Those RV site plugs handle 1-2 cycles daily, but they're more robust, more expensive vers…

A 10kw level 2 charger costs about $2k to install and uses about $1 an hour of power. A 250kw DC charger costs about $50k-150k to install and uses about $30 an hour of power runnin…

I think the bigger takeaway from this is that the US really fumbled our level 2 charging protocol by requiring the cable to be integrated into the charger. In the UK the level 2 ch…

Exciting! I do a lot of FPV drone racing and it always felt ripe for an AI control to take over. Because the video system is so low quality the course is intentionally very high co…

In this case Tesla has been outstanding in terms of software support. Our 2014 S is still getting updates even though it is now "legacy" according to Tesla. That's nearly 10 years …

I'm also not a pilot but, based on a diagram below, it looks like you roll the plane and apply full rudder in the opposite direction. The opposing roll and rudder keep the plane tr…
