FYI, for deep wells you generally have to switch to supercritical CO2 instead of water, for the corrosion issue.

by chris_va 9y ago
Yes, most wells are productive for about 30 years, and then you have to wait a bit (another 30) to let the rock heat back up. The NPV past 60 years is pretty tiny, so it is hard to amortize capex that far out. Worst case, you run them conti

That is sort of true from a grid perspective, but the math doesn't really work out well for geothermal. Geothermal has high capex, low opex, so you need it running 24/7 to amortize the high capital costs. If you combine it with re

by chris_va 9y ago
I'd be careful about getting too optimistic. Conventional geothermal is about 4-5 cents/kWh, on par with natural gas in the US. The dominant capital cost is drilling a large well (you need volume), and so geothermal plants are gen

It seems like it should be possible to at least quantity this phenomenon for each topic by doing some internet segmentation and classification. I assume telling someone that they are in a fringe bucket is not actually an effective way to re

Unfortunately I am not the right person to ask on phytoplankton, but the main concern I have is about geologic stability. Noteably the percentage of the bloom that actually stays out of the food chain. The models for this, when I spoke wit

Cryogenic separation with some thermal cycle recovery is the most efficient method that I am aware of.

That is a good entrepreneurial instinct. If you or a competitor comes in and can create the same value with fewer people, then that drives consumer prices down, which is one of the end goals. Having said that, there is nothing wrong with em

Honestly, once you learn 5 or 6 languages, picking up a new one (not as a deep expert, but enough to functionally contribute to an open source project) takes only a day or so. If you are not there yet, take every opportunity to learn a new

True true, but the 100k is more than just installers. The US employs a lot of engineers, and we export design/technology to the rest of the world.

That's the beauty of capitalism. You can just let it run its course and not worry about it. If something is less efficient, it will not be able to compete in the market for very long.

BECCS is probably the most realistic option: https://en.wikipedia.org/wiki/Bio-energy_with_carbon_capture... ... because removing carbon from 99% pure flue gas is a lot easier than removing carbon at 400PPM from the a

I don't like being cynical, but this is a lot of concrete for not much storage. Also, building a salt water turbine that can last more than about 15 years is next to impossible. Still, it's nice to see people trying to solve the s

Plus Jupiter has a pretty intense magnetosphere that Titan transits. Jovian space has a lot of self generated radiation that makes it less than hospitable. Edit: Titan is a moon of Saturn. Oops.

I think you slightly misunderstood the hypothetical (well, I stated it poorly). In this case, the network is congested and we need to drop packets from a low tier. In the low tier, 90% of the packets are (hypothetically) video streaming. It

Continuing the hypothetical :) Let's say we need to drop packets from my lower tier. We'd prefer to keep a good experience for those customers if possible, so it would arguably be preferable to drop lower utility packets rather th

This hypothetical company wants to drop packets from lower tier customers first, when congested, and oversubscribe their fiber to reduce costs.

To be fair, your "arguments against net neutrality are all about legalizing extortion" already sounds a bit "ultra biased". What if someone wants to start an ISP, and charge less for a lower QoS band? Is that legalized e

While they would prefer Pence, their base is still enamored with Trump. The legislators are scared, and don't want to endanger their reelection until he is no longer popular.
