Hub and spoke is primarily used to fill large planes. If you have 10-20 passenger electric planes you'd land at some random county airport, eat a hamburger or a taco while the plane recharges, then get back on the same…
Yes, I read the underlying paper a while back. It only looks at the very first step of a Dow-like process, before any electrochemistry happens. Instead of dumping hydroxide in a tank, they expose it to hydroxide in a…
They mention that they are doing electrochemistry. A huge portion of historical magnesium production is from electrolysis, including the only operating plant in the US. Past methods have used lime to precipitate…
In this case it is boil sodium, condense sodium to heat air, run air through turbine.
Quaise wants to use old coal plants. So yes if you can drill down super deep to hot enough temperatures.
Will your system be robust to changes in solar farm design? Like if the industry goes towards the Erthos model of installing panels on the ground without racking or trackers?
Germany has a 220 euro/kWh feed in tariff subsidy for geothermal.
Drilling cost is usually estimated for drilling in sedimentary rock with assumptions about how casing is run ;) It is possible that drilling 30,000' of granite has conditions that make the estimation model irrelevant. 5…
Tesla was founded in 2003, Rivian in 2009. So Tesla took five years to start Roadster production, while Rivian has taken 12 years until first customer deliveries. Maybe Rivian will ramp faster. Sam Korus tracks the…
The data is observational, which generally means you should ignore it. It is too noisy. There were those studies that showed moderate alcohol use improved health and only heavy drinkers saw detrimental health effects.…
The people I know with electric cars charge at home the vast majority of the time. Swapping adds a lot of complexity and cost in the pack design. NIO is doing swaps as another commenter pointed out, but more customers…
The problem here is the form factor of the cell as much as the chemistry. Pouch style cells are very difficult to regulate temperature in. This is a key reason why other automakers like Tesla use the small cylinder…
This must be surprising to people, but the prairie co-evolved with ruminants like cows and buffalo. It literally dies and undergoes desertification without them. Buffalos can't breed fast enough to fill this niche for a…
I think there are enough hackers that come from agricultural communities to give it a little boost. If I had discussed whether cows were evil or not, it looks like it might have gone to the front page! It is hard to…
Did you choose batteries for the first version to simplify the power train? Also, why use hydrogen instead of a cheaper, buoyant neutral fuel like propane? If you are worried about the carbon, you can always buy direct…
Is the chain open source with permission-less validators?
austinvernon.com was taken, I had the ENS name, and I was curious about IPFS, so I used it. The system works surprisingly well, mostly thanks to Cloudflare. I've only been using it for a month, though. And its a static…
Thanks! If I would have known it would go to front page of Hacker News I would have had one of my construction science friends proof read it first! I've been writing for fun and to learn and have always been curious…
You are 100% correct. This has been a common term in the manufacturing industry when focusing on ergonomics safety and reducing repetitive stress injuries for quite some time. The connotation has generally been positive…

The Concorde basically used afterburners. It used fuel at incredible rates. Boom is using more modern engine technology that can achieve the high cruise speeds using less fuel. This also increases effective range. So it…
Since you are piggybacking on their system, you'd save on peripheral equipment costs and operating costs, too. The subsystems surrounding these cooling water systems are immense. They need river/lake access for water,…
I think most process engineers at an ammonia plant would be interested to hear about it because it is an elegant solution. I'd focus any pitch on working with them to make sure your process will not interfere with their…
I love this. I started laughing when I read the description. I laughed because a Harvard physicist (funded by people like Bill Gates) had the same idea to use cooling towers for their DAC project in Carbon Engineering…
I was thinking about on boarding investors, on boarding clients, generating reports for this investors, collecting payments, etc. I think the meter data is of the least importance here. I've worked with huge amounts of…
