When I came back from paternity leave with my first child, I told my boss I really wanted to go part time, and he supported me. Google had a standard easy of doing it, so it was just a matter of getting approval up to VP level, which went p

This was discussed a bit last year: https://news.ycombinator.com/item?id=27749497 I've worked part-time for the past 10+ years now, at Google, Makani, and Elemeno Health [60%, 80%, and 40% duty cycle respectively]. It

Without marriage, you don't have a legal framework for breaking up. I know a couple who broke up after 25+ years, a mortgage, and a child together, who had never married. I think the lack of applicable legal precedent made it even mess

The terms are set at the next equity round. The money comes in right away. See the footnote: "Simply put, we’re giving the company money now but at terms you’ll negotiate with future investors."

Agreed, and it'll be a gradual switch rather than a single point, smeared across industries. Likely some operations won't ever go over, but it'll be a while before we know.

Because the expected value of using AWS is greater than the expected value of self-hosting. It's not that nobody's ever heard of running on their own metal. Look back at what everyone did before AWS, and how fast they ran scream

Making flying things lightweight is a means to an end, not the goal or a hard requirement. Makani experimented with a wide variety of solutions before settling on their final model. The initial work on soft kites had serious durability is

While I haven't read this particular study, the standard way to do a trial like this is to compare against the current standard of care, not no treatment.

I don't see a quote as to how much he personally put in. $500M went in so far in total; the rest is milestone-based. I recently saw an 8-figure round in which the lead put in $25K. But they did the legwork to arrange the round and ge

Distillation is pretty expensive, energy-wise, and if you can't run continuously [e.g. if you're trying to use cheap intermittent renewables] you lose energy in the cooling-and-reheating cycles. I have yet to see a significant sou

Ah, that makes sense. Thanks.

Sure, but if you can reduce the cost of lithium-ion batteries by 50% in general, why are you not just licensing that technology to Tesla and others for gigabucks? Or is your cost reduction quite specific to the batteries that eRickshaw dri

What I was getting at was, if $70 is a lot less than a lithium-ion battery costs, do people just steal the batteries and give up the $70?

by uranium 5y ago
$70 < [cost of lead-acid battery] < [cost of lithium-ion battery], so how often does a customer trade the deposit for a battery?

by uranium 5y ago
Yeah, everything here sounds great except for "We also have a patent-pending technology that reduces the cost of lithium-ion batteries by 50%." That's a huge claim, which would immediately be many times more valuable than yo

+1 Can you handle intermittency in your power, or do you need to run continuously? What capacity factor do you assume in your cost model?

Will you be able to complete on cost without carbon credits, at scale?

Living Carbon is doing something similar, working on quick-growing trees that take up enough metals from the soil to slow decomposition.

Salary at all of them. Alphabet has a standard mechanism to scale down your salary/bonus/vesting by your duty cycle, and you get full benefits if you're at at least 50%. For Elemeno it was a more custom arrangement.

That's a very important point. My company has always had unlimited time. We just had an announcement from our HR head that managers are going to start making sure you take at least 2 weeks a year, ideally in a big block. I've

Are those impurities an issue when reselling the CO2?

That makes a lot of sense.

Thanks, that's quite clear. What about the tradeoff vs. large stationary units on power plants? I know other folks are working on that as well; would love to know about how the economics work out vs. truck-sized units.

I presume you're using a heat exchanger to cool the exhaust and heat the discharging pellets. How big a temperature differential are you getting from the exchanger? How much extra energy do you need to put in for cooling? At switcho

Yeah, that's what I was thinking: swapping out a third stage is a much easier prospect; it's just a bulky payload for a 2-stage rocket. But they're saying second stage, so...
