I know most people don’t believe this, but it is likely that electric cars have a good chance of becoming far cheaper than ICE cars over the coming 5-10 years. EVs are complex, but…

Look at the work of Tony Seba, who has analyzed the properties of a possible fully-renewable grid. In his models, you over-provision PV and wind (doable because it is so cheap, and…

Wow, so much willful misinformation. Let’s cover a few! - Steering: indeed the CT uses an innovative, triple-redundant steer by wire system. The steering wheel, which is a squared …

So having memory on-die is revolutionary? Better tell Apple who has been doing it for years. And Tesla’s Dojo is already running processors and memory together at wafer scale, as a…

I think something missed in this discussion is the fact that an EV is so much simpler than an ICE vehicle* that costs will inevitably come down. Many people believe that decent mod…

SpaceX is well underway building their second orbital launch platform and tower at Cape Canaveral in Florida. My understanding is that Boca Chica will be a factory and development/…

Nearly all of the breathless doom mongering has been from one or two small environmental groups who opposed the plant from the start and who keep inventing objections to attempt to…

13 years is immediate? Let’s please not have our future depend on building giant, fragile things that are obsolete technologically and financially before they are even completed. W…

And don’t forget, this was the “revolutionary” AP1 design that was supposed to fix all the bad things about the previous revolutionary designs.

Great work Kody! Thanks. One thing I was hoping to see—-remove MS Word induced junk like “Smart quotes” and “smart apostrophes” and whatever else tends to blow up web text when imp…

I live in a multi-unit residential coop community, and we have managed to install a 240v outlet in each of our 90 carports, and are adding more outlets in open parking areas by mou…

I too wonder about the way good drivers anticipate circumstances and prepare themselves to respond. That might indeed be hard to replicate. But then I realized that detecting these…

I know that righteous indignation is the new national pastime, but I would find it a lot more interesting to hear a more nuanced discussion from this community on the topic of self…

I always find it amusing when the people who deify capitalism and claim the freedom of businesses to do whatever they damn well please start telling private businesses what they mu…

I have never seen a public school that teaches firearm safety (aside from a coach teaching a marksmanship team), and never heard anyone try to claim (until today) it is some kind o…

I wrote my first production program in COBOL back in 1983 at Hewlett-Packard. It basically took reports formatted for the multi-carbon “greenbar” paper that normally went to the bi…

Like most engineering problems, smart design and rigorous execution make a huge difference. Tesla understood that heat management is key to an EV, so they invested in designing a c…

I use this service for my whole family (5 adults) so to continue would cost me $30 per month forever. Sux. Moving email service is not such a big deal, but we have hundreds of Goog…

There’s a level of detail frequently missed when discussing this topic. Most manufacturers fill their cars with dozens of ECUs (electronic control unit) distributed throughout. Eac…
