<p>Civilian uses? Perhaps not, but Iran has always wanted to have a respected navy. Compact nuclear reactors like the type used in submarines with nuclear reactors for their power production require 90%+ enriched uranium. That's one very plausible use of HEU that isn't just "they want to build a bomb".</p>

<p>This seems disingenuous to me, but my personal experience with Coinbase colors my opinion.<p>I had my Coinbase accounts canceled more than 5 years ago. Despite my merchant account with them processing over 1MM USD a year in BTC, they refused to tell me why they terminated my merchant and personal account.<p>At the time, I was buying physical giftcards in bulk from official wholesale distributors for 90c on the dollar, scanning and OCR'ing the redemption codes, and was selling those for the BTC equivalent of $1.05 on the dollar.<p>At the time, some of those merchants had their own plans for digital giftcard distribution and said they didn't want to be associated with cryptocurrencies. I ignored their pressure because I was staying true to the law in regards to various resale doctrines.<p>I suspect some of the larger merchants pressured their financial partners to represent them and put pressure on Coinbase.<p>I didn't mind writing my own bespoke payment processing system to replace them, but the loss of an easy USD <-> BTC gateway did make life quite a bit harder. Since my move to NY, it's been even more difficult because there are few companies that are allowed to operate here.</p>

<p>I live in Ithaca, and Cornell is about to start drilling a test borehole in the coming year. Once the borehole is completed and some tests made, they'll drill a pair of production boreholes about 10,000ft deep.<p>The goal is to pump water down one, and extract it from the other borehole and then use a heat exchanger to pull the anticipated 160F to 180F temperature to provide heat to the entirety of the campus.<p>It's similar to the University's Lake Source Cooling system, which they use the naturally cold water temperature of the local Cayuga lake. At the 250' depth they draw the water in, it's a constant 39F year-round.  The cooling system is used to provide chilled water to all the buildings, and a few thousand homes, removing the need for standard air conditioners.<p>The Lake Source Cooling system has saved the university 20 million Kwh a year, an 85% reduction in power usage, since it was made in 2000. It's hoped that the Earth Source Heat project will have the same kind of impact on the energy necessary for heating.<p>There are a lot of unknowns. Nobody has drilled a borehole so deep in this area before because there hasn't been a reason to do it before.<p>[1] <a href="https://earthsourceheat.cornell.edu" rel="nofollow">https://earthsourceheat.cornell.edu</a>

<p>It looks like a group at the University of Exeter is working on that exact plan.<p>"SeaCURE harnesses two natural properties of the ocean that can circumvent this  problem. (1) The amount of carbon dissolved in a seawater is approximately 150 times higher than its concentration in air, making extraction significantly easier and quicker, (2) we can utilise the ocean’s vast surface area to remove CO2 from  the enormous volume of air sitting above it, rather than having to push all of that air through air-based CO2 capture facilities."<p>"SeaCURE will combine and refine existing approaches to develop a new system that removes  CO2 from seawater and releases the CO2-depleted water back to the ocean, where it will  naturally re-absorb an equivalent amount of CO2 from the atmosphere. Specifically, at the University of Exeter and Plymouth Marine Laboratory we will benchmark established approaches to prepare seawater for CO2 extraction, strip that CO2 from the seawater, and collaborating with Brunel University concentrate the CO2 to high purity. TP Group, a UK based technology and engineering firm with world leading expertise in gas extraction from seawater, will then develop and upscale the most cost effective approach from this toolkit. The SeaCURE team will design a portable pilot plant to remove at least 100 tonnes of CO2 a year. Future testing using the pilot plant would generate the data required to develop commercially viable CO2 removal at the megaton scale, aimed at public and private sector offsetting and the carbon trading market."<p>[1] <a href="https://www.eurekalert.org/news-releases/807198" rel="nofollow">https://www.eurekalert.org/news-releases/807198</a></p>

<p>I disagree. The truck going through the crowd model requires a sacrificial group member. In our country, the lack of terrorist group members makes their individual value higher. that makes an attack that has a higher capex cost more appealing, such as sacrificial drones.<p>A swarm of two dozen drones costing less than $50k could foul all of a passenger airplane's engines within a few thousand feet of takeoff. The evidence would be pretty junked up and there is no easy way to trace it back to the controller while it's happening. No sacrificial terrorist cell member needed.</p>

<p>One of the other issues that your comment shines a light on is that police often book someone under multiple charges. A safe one that the person is likely to be able to be convicted on, and multiple charges that probably don't apply to the situation.<p>This is common because it gives prosecutors the power to "offer" to drop the higher charges in exchange for accepting a plea bargain to the lower, and likely more appropriate, charges.<p>The result of this is that booking information, with the photos, from a drunken bar fight might show the person was charged with assault with a deadly weapon when the final charge will end up being something like disorderly conduct.</p>

<p>From what I understand, ransomware insurance is already a thing. With the policy you get someone who negotiates the price and pays the ransom directly to the ransomware gang, which bypasses some laws against paying ransomware directly.<p>In theory, this helps with lower prices, negotiated support policies with the ransomware criminals to ensure the decryption process goes well, and they keep cryptocurrency available so the policy holding company doesn't have to scramble to get millions of dollars in crypto in a day or two.<p>Similar to kidnapping negotiators, ransomware negotiators often have the experience to produce a better outcome</p>

They were making money with the partnership, and money from sources OTHER than Google is a good thing.<p>After two years of this, Mozilla realized that Pocket was making so much money on paid memberships that it was smarter to use some of their war-chest to buy Pocket outright.<p>That's right, Pocket is owned by Mozilla now and has been for 4 years.

<p>I find it interesting that there were spikes of readings at certain times of day and night. Coupled with the information that the apartments have a VoC barrier, my intuition is that there is a timer somewhere that turns on a fan to clear out the VoC capture space created by the barrier and exhaust the contaminated air to the outside.<p>If the VoC that's bothering her is heavier than air, it could be being blown upwards from the ground level and then settling back over the building and falling back down and finding its way back into her apartment somehow, like through the range hood, dryer exhaust, plumbing stacks, open windows, or just cracks due to poor craftsmanship.<p>If she was still at the site, I would recommend looking for what appears to be an exhaust vent of some kind that might be tied to the VOC barrier system and putting a sensor there and seeing if the readings correlate to the timeline of unusual readings in her home</p>

<p>Nuclear power is expensive and complicated, but not inherently so. A lot of the causes of the problem is political decisions and bureaucratic processes.<p>There are many designs for nuclear reactors that are simpler, safer, and more suitable for smaller communities, but various government nuclear regulation agencies around the world have such a high bar for entry that those designs will never be put into practice.<p>In the US, if you want to operate a nuclear reactor, the design has to be vetted first. To vet the reactor, you have to convince the agency to let you build a full-scale test reactor and convince them that the design is likely safe before building the test reactor. If anything about the test reactor makes them uncomfortable, the design will be denied and the reactor won't be allowed to operate and cannot work as a template for future reactors.<p>This creates a very difficult and expensive bar for entry into the market. For a large reactor, a company would have to invest billions of dollars for a decade before they could even begin to hope to operate to pay back the loans, and even then there is no guarantee that they'll be allowed to operate the reactor to sell the electricity.<p>That is, unless they use one of the existing pre-approved reactor concepts that were designed in the 70's and have known flaws (albeit, with known ways to reduce the risks of those flaws)<p>Nuclear radiation might be damaging, but it's not really a big deal as long as the design prevents accidents and there are safeguards to prevent the uncontrolled release of radiation.<p>You are incorrect about the availability of uranium. There is a LOT of uranium available for use, and we could run entirely on it for thousands, or tens-of-thousands of years. Many mines are shut down simply because there is far more supply than demand.<p>Solar is an excellent source of energy, with long life spans of the equipment but it's only functional for anywhere from 6 to 16 hours a day, depending on your latitude and the weather. The ideal places for solar farms are often far from the highest concentrations of consumers.<p>Wind is also great, but it wears out fast because of the moving parts and friction, even the friction of the air moving across the blades wears them down. It's not uncommon for lifespans to just last a decade.<p>Both wind and solar suffer from risk because manufacturing predominately takes place over seas and trade wars, or real war, could interrupt supply. For solar, that's not as big of a deal for existing infrastructure, but for wind it could cause problems.<p>Our grid, in the US, is pretty interconnected. There are improvements that can be made, but it's pretty redundant in general.<p>The ideal solution would be small but safer nuclear reactors, no bigger than an office building, that can supply power to 50k or 100k homes.  Place them within 20 miles of urban centers.<p>The problem is that it takes a lot of political will to build a nuclear power plant because everyone is afraid of that. Bigger plants are often desired because plant owners need to invest the decade and tens of millions of dollars getting not just approval from the NRC, but approval from the people and government within 20 miles of the plant.<p>Smaller and safer plants might be cheaper to build, but there is no savings when it comes to that approval and acceptance process.</p>
