Hi HN! I’m Rob, Founder of Prometheus. We’re removing CO2 from the air and turning it gasoline, diesel, and jet fuel. Since we use zero-carbon electricity from sources like solar and wind to make our fuel, there are no net CO2 emissions when you use it.
An article about us came up on HN recently and people seemed interested (https://news.ycombinator.com/item?id=19792412), so we thought it would be good to try to answer some of the questions we saw there and try to dive in some more to any questions that follow!
The only inputs to make the fuel are CO2 and water (both from the air) and electricity. The only outputs are fuel and oxygen. One way to think about it is that making fuel is reverse combustion. The process isn’t super efficient (we expect 50-60% overall efficiency at maturity), but it turns out that doesn’t matter as long as the electricity is zero carbon and low cost. If the cost of our equipment is also low, then we believe we can not only make zero carbon fuel, but actually compete on price with fossil fuel.
We’re not the first to make fuel from the air - in fact Google, Audi, Carbon Engineering, Global Thermostat, Climeworks, and labs at universities and national labs have all done it before us. What no one has been able to do so far is do it at a low enough cost to compete with fossil fuel.
The thing that’s new about what we’re doing is that we have gotten rid of all the thermal processes normally used, and instead use a process that uses only electricity (no natural gas, etc) and does it at room temperature. This is a big deal for both capital cost and for being truly carbon zero. We can use inexpensive materials, which keeps our cost low, and can start up and shut down quickly, which allows us to run intermittently, matching the intermittent nature of many renewable energy sources. We can also only run when the power is at the price we want.
Digging in to some more details, we absorb CO2 and water vapor from the air into an aqueous electrolyte. We then react the CO2 in the water with a copper catalyst to directly make alcohols like ethanol, butanol, propanol, etc. Both of these things have been done by many others and the science is known. Normally at this point one would have to use a thermal process (distillation) to get the fuel out of the water, and this is expensive and makes the economics really hard to get right. We don’t have to do this step thermally though, because we have a carbon nanotube membrane that replaces it, extracting the alcohols from water in a single step at room temperature. This makes a huge difference in cost. The last step is that we up-convert the alcohols to gasoline, diesel, and jet fuel. This last step is also well known and we can actually buy this step from others.
The carbon nanotube membrane that makes this all work is the product of 6 years at my previous startup, Mattershift. I was developing it for desalination and water purification. About 3 years ago I realized it could do this job, but it wasn’t clear that a startup could raise money for such an ambitious effort, especially one linked to a political issue (unfortunately) like climate change. When I saw the YC request for startups in carbon removal, I knew that the timing was right, and I founded Prometheus to do it.
Please let me know if you have more questions or feedback. I’ll do my best to answer any questions, but please excuse if I’m not able to go too far into details like our piping and instrumentation design, or other really specific things we wouldn’t want to help competitors with.

On Thursday, April 11 at 6:35 p.m. EDT, Falcon Heavy launched the Arabsat-6A satellite from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. The satellite was deployed approximately 34 minutes after liftoff. Following booster separation, Falcon Heavy’s two side boosters landed at SpaceX’s Landing Zones 1 and 2 (LZ-1 and LZ-2) at Cape Canaveral Air Force Station in Florida. Falcon Heavy’s center core landed on the “Of Course I Still Love You” droneship, which was stationed in the Atlantic Ocean. You can watch a replay of the launch below and find out more about the mission in our press kit. IFrame

Hello, HN! We're Michael and Liana, co-founders of Bottomless (https://bottomless.com)
Bottomless automatically re-stocks coffee using a smart scale. Users leave their coffee on the scale, then we detect the perfect time to trigger re-orders. We ship the scale for free when customers buy their first bag.
We met in college, and bonded over talking about businesses we could build together. You could say we've kept in touch since then: we're now married. Bottomless was born out of our frustration managing our household stock levels. We always seemed to be running out of one thing or another.
When we thought about it, we realized that restocking was a universal problem.
But if this was such a big problem, why was there no great solution? Subscriptions should be a solution, but they don’t work well for items that aren’t used on a set schedule. It seemed that if we could capture data on usage and stock levels in a passive way, we could solve the problem. Thus, Bottomless, the concept, was born.
The market for stuff people repeatedly buy is enormous. (We'll leave an exact estimate up to the reader's imagination.) We decided that to start we'd establish a beachhead with a single market. We landed on selling premium coffee because it's cheap to ship and has good margins. It also is much better shipped straight from the roaster than bought at the grocery store.
In the beginning, we built the simplest thing possible to test if the concept would work. We hacked together a scale prototype, made five of them and got them into the hands of friends. We bought coffee from roaster websites with our customers’ addresses to bootstrap supply.
The goal was to test if people would leave their coffee on a scale, and if we could reorder at the right time. It turns out they would and we could!
Since then, it's been a matter of making larger batches of scales. We bought a few 3D printers and acquired quite a few burned fingers from soldering.
We've benefited from a few technological tailwinds. For one, smartphone supply chain has driven down the cost of components quite a bit. We've been able to build hardware that works for this business model out of super cheap WiFi modules and LiPos. Also, the level of open source software for ML is quite powerful and well-documented.
We're aware that we are just scratching the surface of re-ordering hardware. We'd be interested to hear ideas that the community might have about this space!

Hi HN! We are Yuriy and Oleg, founders of Axdraft (https://business.axdraft.com/en/business). Axdraft offers free legal documents for startups.
We have built Axdraft, because we believe that sometimes founders don’t need 20-page ironclad contract, 2 weeks of negotiations and detailed explanation of all risks. On early stages you just want to have a good, balanced agreement fast to move the deal forward while it's hot. The biggest difficulty here is that lawyers push us to perceive contracts as unique and, therefore, not possible to automate. Usually, by saying unique, they mean that there are 20-50 possible variations of a clause in the contract.
We are a team of brothers, who combine legal and tech expertise, Yuriy was a lawyer for almost 8 years at one of top law firms in Europe and when he started noticing that even the most complex legal transactions have many patterns, he reached out to his brother Oleg, who at that time was Senior Software Engineer at Booking.com in Amsterdam.
Our main differences compared to Clerky, LegalZoom, RocketLawyer and similar solutions are:
- we focus on startups, which makes the content more tailored; 2. we offer documents for free, because I see little value in the legal document itself. The main value of a lawyer, in our view, is in counseling, sharing the liability and providing you assurances; 3. we offer plain English description of the implications for each choice you are offered when drafting a document; 4. to use Axdraft you don’t have to register, because we want to create flawless and super-fast experience for founders to create legal documents; 5. we are happy to customize documents of registered users with their logos, company details and some custom language upon request.
Currently, we offer founder to founder review, which is not a legal review at all, but more a business advice from a fellow founder, who is eager to share his experience with similar contracts.
We estimate the market for this product to be less than 1 bln USD at the moment, but we expect it to grow as the number of startups founded each year increases and as we expand into a larger 7 bln USD market of small businesses (under 20 employees) in the US.
We are really excited to hear your feedback about Axdraft. Please try it out at https://business.axdraft.com (registration is not required) and let us know what you think.

We're Rohit, Edul, Prince, Alankar and Snehil. We’re building Mudrex (https://mudrex.com).
Mudrex helps traders automate their trading without having to code and spend a lot of time and money building infrastructure. Though we have started with cryptocurrency trading first, our goal is to help anyone who wants to get into automated trading or investing across any asset class.
We had been trading cryptocurrencies for some time and were not able to track trading opportunities across 1000s of currency pairs for 24 hours a day and 7 days a week. We thought of automating our trades, but faced challenges like being unable to access historical data, building a testing framework to test strategies on historical or live data, and maintaining connections and orders on multiple exchanges. Also, since it was all coded we were not able to quickly iterate on trading ideas, since for simplest changes we had to dig into code and deploy new strategies to retest them. That also made it hard to have a log of all the trades, strategy changes, back-tests, papers to compare things at one place.
After talking to hundreds of traders, we found out almost all active traders were facing the same problems, so we decided to build Mudrex. At Mudrex traders can quickly build any kind of trading strategies using 150+ indicators, 50+ candlestick patterns, price or volume action. They can test their trading strategies on historical and live data to optimise and automate their trading by connecting their order using exchange API keys.
Cryptocurrencies are just a start for us and we have been growing very quickly since the launch and getting feedback from more and more people every day. There are millions of traders out there, trading manually across different asset classes just because they don't have capital and resources to build an automated trading infrastructure from scratch. We want to solve all of their problems so they can focus on building trading strategies instead of spending too much time on infrastructure issues. One of our users defined our goal as "democratising algorithmic trading and investing" and we are working hard every day to get closer to that.
For the next 2 months the platform is free to use but we will charge a $0-$100 monthly subscription fee depending on usage with a free tier available.
Next on our roadmap are things like a code editor (where traders can build custom indicators using minimum coding), a marketplace between traders and investors, and integrating equities and forex.
We dream of reducing the gap around financial opportunities between the wealthiest and the rest. We just got started and are going to face many technical/design/operational challenges, but with the help of our users' feedback and support we feel we can achieve it. Looking forward to hear feedback from the HN community to keep going in the right direction!

3/19/06 From The Lord, Our God and Savior
The Word of The Lord Spoken to Timothy
For All Those Who Have Ears to Hear
Thus says The Lord God of Israel: Woe to the #kingdoms of this #world! Woe to the false #religions of this world! The #atheist shall have it far better than you, when the #wrath of the great and dreadful God has come! Woe to the #king of the north! Woe to the #kings from the rising of the #sun! Woe to the king of #Persia and the #people of #violence! Woe to every #nation and people, who say, “Come, let us put an end to #Israel as a nation. Let us utterly #destroy them, that the name of Israel may be remembered no more!”... BEHOLD, I AM AGAINST YOU! Says The Lord God.
Thus says The Lord, to the king of the north: Come and mount up your #troops, and take #flight. Call upon your #agreement with those of the rising sun. Honor your #covenant with the people of #violence. #Cast your #devices and #launch all your #weapons of #war. Come against My #chosen people and the land #promised to their #forefathers, forever! COME! Says The Lord. Fulfill the #evil desires of your #wicked #hearts. For you shall #fall, and you shall not be found! Says The Lord of Hosts. You shall be a #valley of #dead and dry #bones, buried in the #land you came to #destroy, for it shall #consume you! - #Food for the #birds, dwelling place of the #worm.
Therefore come, I say! Come, and leave your spoil and your rotting #flesh! For you shall surely stumble, you shall fall, and you shall not be found! And by your falling shall the name of The Lord be #glorified in every land, even unto the ends of the earth! For this is but an #awakening, and many shall behold it, the #mighty and #awesome #power of The Lord!
Behold, the #earth shall be #shaken, the #clouds shall burst! I shall command #pestilences to come upon you; they shall cleave to you and #drink your #blood, and you shall be driven #mad. For you shall #stumble, you shall #fall, and you shall not be #found! (Save a sixth part whose #hearts I know; they shall return home and be spared.) For in your eagerness to spoil shall you become the #spoil, and sustain My people seven #days.
Swiftly shall I destroy this great #multitude who come out to #fight against Me, who seek to destroy My people, Israel! For they shall be driven to the #ground by #fire, by #hail, and by #thick #darkness! FOR #STRONG IS THE LORD WHO DEFENDS ISRAEL!
_Behold, My #countenance has changed!
My #face is set hard against you, O #enemies of Israel!
My #arm is outstretched and ready for #battle!...
Thus that which is #written shall be fulfilled,
And that which is determined shall be done,
And you shall be left utterly desolate!...
Then all shall know, I AM THE LORD!_
Yet #understand this, O #house of Israel: I do not do this for your sake, but for My #holy name’s sake. For My name is profaned among the nations. And you, O Israel, have not obeyed My #Word, neither have you walked in The Way I have shown you. For you yet reject The One who I had sent to you, The Holy One who was #glorified upon the #tree. Thus His #blood remains upon you. For you are the #children of your #fathers, the #descendants of those who killed The #Author of #Life!
_Thus I have spoken it,
And it shall surely come to #pass...
Says The Lord of Power and Glory._

We’re Jorge, Kevin and Sean and we’re building GoLinks (https://www.golinks.io).
GoLinks is a platform that allows you to easily manage and share links by letting teams create a short link for any internal URL within a company. These links are easy to remember and share, so you don't have to bookmark or copy and paste them in emails.
Each day we use and share hundreds of links to get our jobs done, without considering how long it takes to access and share these resources. It’s one reason why many of us leave tabs open in our browser: we don’t want to spend the 5 to 10 steps to navigate back to that important page. With GoLinks, you’ll be able to deep-link directly into any application with just a simple keyword entered into your address bar. This allows links to be conversational. For example, one employee can create the keyword “go/review” to point to the annual review page in Workday. Later in a meeting, that employee can mention, “Remember to visit go/review to fill out your annual reviews!” Now anyone in that meeting can remember and access the link “go/review”, without digging through their email or Slack.
Golink systems are commonly used in many big tech companies such as Google, Linkedin, Twitter and Airbnb, built by internal tools engineers in those companies. These systems have become an integral part of the way tech companies share internal links.
When we started our careers in tech, we would often visit each other for lunch at these tech companies and we began to notice the same go/links everywhere. In the hallways, cafes, break rooms, posters. fliers and TVs, there would be these keywords prefixed with “go/” that allowed employees to quickly access information on their devices. The employee could enter a shortened URL like go/food into their mobile browser, or desktop, and could access the lunch menu for that day. An easy and simple concept, but an extremely powerful method for internal communication.
Although these systems are ubiquitous in large tech companies, we noticed there was nothing on the market that catered to startups, midsize, or non-tech companies. Companies usually don’t have the time or the resources to build sophisticated internal tools, so we set out to create GoLinks as a Service.
The challenge was building an internal tool for companies that may not have any internal infrastructure. For example, large tech companies have infrastructure so when you connect to the company Wifi or access the VPN, you can access the internal company network. This allows users to access the “go” domain on the network, which resolves the deep link redirection. For smaller and midsize companies, employees might be 100% remote or working in a coworking space, or maybe the company never got around to setting up an intranet. We had to build a product that did not rely on assuming internal infrastructure.
We were able to replicate the functionality of an internal network, and the simplicity of a short-link redirect system, by creating browser extensions for each of the popular browsers. The extension would proxy the “go” domain to our server and we authenticate and redirect the user to the correct location. Now coworkers can be on any network and any wifi, and as long as they authenticate in their current browser, we can find their company’s internal links.
We are startup-friendly—anyone under 10 users can get started completely free—but our main initial focus is on enterprise clients.
If you’ve ever used our GoLinks or any company's golink system, let us know how it’s changed your daily workflow. Thanks for reading. We appreciate your ideas and feedback!

We’re Everest, Andrei and Sabera, the founders behind Fuzzbuzz (https://fuzzbuzz.io) - a fuzzing as a service platform that makes fuzzing your code as easy as writing a unit test, and pushing to GitHub.
Fuzzing is a type of software testing that generates & runs millions of tests per day on your code, and is great at finding edge cases & vulnerabilities that developers miss. It’s been used to find tens of thousands of critical bugs in open-source software (https://bugs.chromium.org/p/oss-fuzz/issues/list), and is a great way to generate tests that cover a lot of code, without requiring your developers to think of every possibility. It achieves such great results by applying genetic algorithms to generate new tests from some initial examples, and using code coverage to track and report interesting test cases. Combining these two techniques with a bit of randomness, and running tests thousands of times every second has proven to be an incredibly effective automated bug finding technique.
I was first introduced to fuzzing a couple years ago while working on the Clusterfuzz team at Google, where I built Clusterfuzz Tools v1 (https://github.com/google/clusterfuzz-tools). I later built Maxfuzz (https://github.com/coinbase/maxfuzz), a set of tools that makes it easier to fuzz code in Docker containers, while on the Coinbase security team.
As we learned more about fuzzing, we found ourselves wondering why very few teams outside of massive companies like Microsoft and Google were actively fuzzing their code - especially given the results (teams at Google that use fuzzing report that it finds 80% of their bugs, with the other 20% uncovered by normal tests, or in production).
It turns out that many teams don’t want to invest the time and money needed to set up automated fuzzing infrastructure, and using fuzzing tools in an ad-hoc way on your own computer isn’t nearly as effective as continuously fuzzing your code on multiple dedicated CPUs.
That’s where Fuzzbuzz comes in! We’ve built a platform that integrates with your existing GitHub workflow, and provide an open API for integrations with CI tools like Jenkins and TravisCI, so the latest version of your code is always being fuzzed. We manage the infrastructure, so you can fuzz your code on any number of CPUs with a single click. When bugs are found, we’ll notify you through Slack and create Jira tickets or GitHub Issues for you. We also solve many of the issues that crop up when fuzzing, such as bug deduplication, and elimination of false positives.
We’ve noticed that the HN community has been increasingly interested in fuzzing, and we’re really looking forward to hearing your feedback! The entire purpose of Fuzzbuzz is to make fuzzing as easy as possible, so all criticism is welcome.

We’re Hannah, Esteban, Jaiden and Max, the founders of Our World in Data (https://OurWorldInData.org). We’re a nonprofit in the YC W19 batch.
Our World in Data is a website that shows how and why global living conditions and the earth's environment are changing. Is the world becoming more violent? Is an end to poverty possible? It's hard to know because daily news focuses on negative single events, and misses long-lasting changes that reshape the world.
We’re a group of researchers from the University of Oxford trying to solve this problem. We bring together data and research from many different sources often buried under jargon in static, outdated documents. We present a global perspective on living conditions and environmental change through interactive data visualizations and short explainers.
Max started Our World in Data in 2013 whilst working as a researcher at the University of Oxford. The project was born from a frustration that we are so poorly informed about how the world is changing—we fail to notice the important developments shaping our world and are not aware what is possible for the future. It has now evolved into a full-time project with a small team of researchers and web developers (we’ll be looking for a new web developer this week!). We’re all driven by the same motivation: to make sure data and research on how the world is changing is free and accessible for everyone.
We cover many topics, ranging from poverty to health, environment, energy, education, and violence. Our data and analysis are available at global, regional and country levels. And we try to provide the longest-term data we can, often going back many decades or centuries.
We average more than 1M users per month; these range from policymakers to journalists, academics to school teachers. But we’ve also had some use cases that took us by surprise: To many readers it’s unexpected to see that the world has made substantial progress in important aspects and psychologists have recently told us that they use our website to help patients with depression and anxiety. We did not expect this use of our work at all and asked them for more details. One of them explained: “Facts can be a powerful weapon against fear, a gloomy worldview, learned helplessness. So I help clients find facts at Our World in Data.”
We usually work remotely, because we are not all based in the same country—this is the first time that we were able to find a 3-month window of time to move to California and work together.
We come from a university environment and applied to YC because we wanted learn from the startup and the technology world. The work at YC and the contact with the partners and other founders have definitely given us an entirely new perspective on how to work.
We’re here at HN because we are sure we can learn a lot from the community here. We knew there had been HN threads on aspects of our work before – but after a recent search (http://bit.ly/OWID-searches-on-HN) we had no idea there were so many. It’s amazing to see that these posts created such great discussion within the HN community.
Our website is here: https://OurWorldInData.org. We are a non-profit and all our work is entirely free; open access research (Creative Commons licensed) and open source code. If you’re interested in supporting this with a donation to us you can do so here: https://OurWorldInData.org/Donate. Or if you have any other queries, you can reach out at firstname.lastname@example.org.
We would really appreciate any feedback you have on what we can do better. Thank you!

We are Modern Labor (https://modernlabor.com). We pay you to learn to code. We take people with little or no software skills and pay them a livable wage for 5 months while they learn to code, using our content, most of which is open source. In return graduates pay us 15% of their income for 2 years if they are earning over $40,000.
The company is born out of a phenomenon I’ve been fascinated with for a long time: many people wake up every day at 7am to work at a low-paying job but they often have difficulty completing a class that might help their future. For some people, it might just come down to money. A job pays now, a class pays off in the future and only maybe. For many reasons--time, energy, motivation, financial pressures--many choose or are forced to choose the job that pays now and their long-term income sometimes suffers as a result. So we had an idea: Why don’t we just pay people to learn? So that’s what we do: we pay people, now, to learn an in-demand skill.
I remember back when we were building Leif, a startup we sold last year. I told Dickie, one of our co-founders, if I only had an extra $10,000 I could build out the product to an acceptable quality for a couple months. Otherwise I had to work. He ended up giving the money. We sold the company the next year for a good outcome. That couple months of being able to focus made a big difference in the quality of the product and I think ultimately on how successful we were with customers. We think Modern Labor can give people enough time to make a real change in their lives.
15% of gross income is a lot. Why so much? It comes down to simple risk/return: returns must be adequate given the risk. If it sounds a lot like Lambda School (YC S17), you’re right. Our former company Leif arranged financing for them. We discovered Austen (CEO) here on HN. It’s a big space, though, and our program is different from theirs. We have fewer mentors and our focus is on giving money to students.
How many people will do our program? About 50,000 people pay to attend coding bootcamps in the US each year. We believe, and may be wrong, that a lot more people will choose learning when we pay them to do it.
Thank you HN -- HN was the first thing people told me to read when I was learning to code and it’s been a big part of my life ever since. Happy to answer any questions and looking forward to hearing your ideas and feedback!
Right now it’s $2000/month
