Top Tech Reddit IAmA's The latest Tech IAmA's collected from Reddit My name is Sarvesh Sadana. I built a working fusion reactor in my garage. I also conduct research at Berkeley and run a 501 (c)(3) nonprofit. AMA! Hiya Reddit! I'm a longtime lurker, but some friends convinced me to do an AMA.

My name is Sarvesh Sadana. I'm currently a senior (17) in high school.

For the past year and a half, I've been building an Inertial Electrostatic Confinement fusion reactor (fusor) in my garage. It utilizes an extremely powerful electric gradient in a high vacuum to accelerate positively charged ions toward a negative central grid. The charged ions have such high velocity (30 million Kelvin) that they collide with one another and fuse. Half of those fusions produces a neutron, which is then measured using a He-3 proportional counter and a digital oscilloscope. It took hundreds of hours, but as of September 16, 2017 I achieved fusion.

The project I'm currently working on is a liquid helium generator. It consists of a high-psi air compressor, high-pressure stainless steel tubing, a reservoir, a regulator, tanks of nitrogen, neon, helium, and more. It utilizes the Joule Thomson effect to cool the gases down to near absolute zero (helium liquefies at 4 Kelvin, and has a JT inversion temperature of 45 Kelvin). The generated liquid helium will be used to cool a superconducting electromagnet, which will reach extremely high levels of magnetic flux.

I've also been conducting research at UC Berkeley for the last 6 months. I create composite 3D printing filament with superior mechanical and thermal properties. I'm currently working with Carbon Fiber Reinforced Polymers, and their potential applications in 3D printing. It's super exciting stuff!

Lastly, I'm also the co-founder and CEO of a nonprofit called Shoecyclist. We hold shoe donation drives where we donate new and used shoes to the homeless. We also have several local chapters across California.

Feel free to ask me any questions about anything! I have opinions on everything from Star Trek to scientific publishers. (My fusor) (Pic of fusion plasma) (Liquid helium generator - in progress)

TechnologyWe're MegaBots, Team USA in the Giant Robot Duel. Our robot fights tomorrow - AUA! Hey Reddit, I'm here again!

After starting standup at 19, I wrote, starred, and produced my own television show TITUS from 2000-2002. After I pissed off the Network President and the show got canned I've done seven 90 minute comedy specials and I'm working on my eighth called Amerigeddon, which is touring now.

I also just finished my first feature film called Special Unit, a cop movie starring actors with real disabilities and my emotional ones. We used handicapped actors in a way that has never been done before, in a balls out comedy that is as if Mel Brooks made Lethal Weapon with retards. You can check out the movie below.

TechnologyI discovered a novel design for Sustainable Energy Generations Systems and released my proprietary rights into the public domain. AMA! While completing my MSEE degree, I got an idea for how to design sustainable energy generation systems. To give some background, the electric power system delivers electricity to homes and buildings to power televisions, refrigerators, computers, and every other device that plugs into an outlet. A sustainable energy generation system is an off-grid (stand-alone) electric power system that can independently provide reliable electric power to a home/building from renewable energy resources. The main challenge in designing sustainable energy generation systems, i.e. solar and battery storage, is determining how much solar and how much storage are required to reliably supply power year-round.

By considering oversized PV, I pioneered an algorithm that approximates the energy storage requirements for increasingly oversized PV. The result was a graph of all possible configurations of oversized PV and storage, and I found an inverse relationship between PV and storage. Here is an animation of what this looks like.

This relationship is important to optimize for the cheapest system. Since PV and energy storage have different costs, the algorithm computes the price for each system and determines the most cost-effective configuration shown by the red “x”. This data represents the results for a residential home; however, this solution is scalable to any size.

After graduating, I founded OffGrid, an organization to design sustainable energy generation systems. My work involved working on the design, patent application, and funding opportunities. Unfortunately, I was unable to secure funding for this organization and found a job a few months after. I uploaded the algorithm on GitHub and released all potential proprietary rights, pertaining to the system, into the public domain. AMA

My Proof is a technical document with more information about the system and a link to the algorithm.

TechnologyWe are a solar racing team about to embark on a 3,000km journey through the Australian Outback in a solar car that we built, AMA! Hello, Reddit! Mike from UC Berkeley's public affairs office here. Since free speech on college campuses is a hot topic - especially at Berkeley - I asked the dean of our law school, Erwin Chemerinsky, to sit down for an AMA to discuss it and other subjects.

Erwin is an extremely humble person, but I need to quickly brag for him before we begin: In addition to being our law dean, Erwin is one of the country's foremost scholars of constitutional law, and earlier this year was named the most influential person in legal education in the United States by National Jurist magazine. Before coming to Berkeley, he helped establish UC Irvine's law school, and before that taught at Duke University and USC. He has argued cases before the U.S. Supreme Court and the U.S. Court of Appeals, has written hundreds of law review articles, and is the author of ten books - including “Free Speech on Campus,” his latest. You can learn more about him here.

I'm just here to facilitate; Erwin will be responding to all questions himself. No need to stick solely to the topic of free speech, either - he's willing to discuss all manner of legal subjects. He'll begin answering questions at about 5:30 PM pacific time.


EDIT: Mike here again. I'm afraid that Erwin needed to sign off for the evening, but he asked me to pass along the following: "It was a pleasure to participate in this, thank you for all the very good and well-informed questions - I answered as many as I could and I'm sorry I could not do more. I'd love to do this again." We'll try to make that happen!

TechnologyWe’re Kor Adana and Ryan Kazanciyan of Mr. Robot My name is Sean Stratton I am a 24 year old environmental scientist and I am currently running for New Jersey District 18 Assembly as the Green Party candidate. I’m here to talk to you about my political platform and the experience of running as a young adult and third party candidate.

I decided to run for office 5 months ago after a friend’s tap water test came back containing 82 ppb of lead. This led me to research the federal Lead and Copper Rule along with conducting Open Public Record Act requests (for anyone not in New Jersey this is called Freedom of Information) to my hometown and the New Jersey Department of Environmental Protection. What I found was that my hometown was not sampling the correct locations as per the federal regulations and they were not providing the correct notification to residents who had their homes tested. From this I began to look at other towns and found that we have multiple towns and cities here in New Jersey that have breached the federal action level for lead in residential drinking water. 3 examples are Newark, Trenton, and Milltown. This is significant because even during the height of the Flint Michigan crisis, Flint never exceeded federal standards.

This is when I decided I would run for office; I believe that everyone has the right to clean drinking water and in order to provide this we need to drastically rebuild our infrastructure including our water distribution system. I also believe that every worker deserves a livable wage which is why I support increasing the minimum wage to $15 per hour here in New Jersey. Finally, I believe that all citizens no matter how rich or how poor have the right to healthcare. I support universal healthcare and will push for a New Jersey single payer healthcare system.

EDIT: Wow! 7 hours and I definitely got way more questions than anticipated! Was great talking with everyone and I definitely learned a lot! Remember to vote in your state and local elections, they're important!

TechnologyWe're scientists, engineers & communicators for NASA's Cassini mission, which makes its #GrandFinale plunge into Saturn next week. AUA! Our short bio: After two decades in space, NASA's Cassini spacecraft is nearing the end of its remarkable journey of exploration. Having expended almost every bit of the rocket propellant it carried to Saturn, we will deliberately plunge Cassini into the planet on Sept. 15. Why? To ensure Saturn's moons will remain pristine for future exploration—in particular, the ice-covered, ocean-bearing Enceladus, but also Titan, with its intriguing pre-biotic chemistry. Only one week remains before the spacecraft's final chapter in the skies of Saturn. What would you like to know about the science and engineering still to come for Cassini? Ask us anything!

JournalistBlood test: $522 or $19? We’re New Orleans journalists digging into the murky waters of health care pricing. Ask Us Anything! We’re Jed Lipinski, a reporter for | The Times-Picayune, and Lee Zurik, a reporter for WVUE Fox 8 News.

For the past few months, we’ve been writing about the cost of health care in Greater New Orleans as part of our “Cracking the Code” series. With help from ClearHealthCosts, a New York-based journalism start-up, we’ve exposed how the cost of common medical procedures varies dramatically depending on your provider or health insurance.

Routine blood tests, for example, can be had at Touro Infirmary for $522, or for just $19 half-a-block away at Clinical Pathology Laboratories. At one local radiology facility, United Healthcare pays $1,005 for an MRI of the spine, whereas Blue Cross and Blue Shield of Louisiana pays just $464 – a difference of $541.

Through our reporting, we learned that the cost of most medical procedures is intentionally hidden from the public. As a result, most patients have no idea what they will pay prior to visiting the emergency room or undergoing an operation. This directly benefits insurance companies and health care providers, whose prices often have no relationship to the cost of the service itself. Overcharging is the norm.

Our goal throughout has been to enable consumers to make educated cost decisions about their health, the same way they can about food at the grocery store or fuel at the gas station.

Thanks for having us. Ask us anything!


Edit: Stories call, so we're stepping away from the keyboards. We'll be back to answer your questions throughout the day though, so keep posting them if you have them.
