This would be an even bigger deal for remote spacecraft that rely on the heat from on-board nuclear reactors.


I think you are thinking about an RTG instead of an actual reactor.


Some space craft have actually had full reactors on them believe it or not.


There were indeed real nuclear reactors with thermoelectrics being launched in the cold war.

However, thermoelectrics have an efficiency well below 10% (maybe a bit better with this improvement but not much). For that reason, future reactors in space will likely use Stirling engines instead.


Correct. Space stirling designs* (and tested engines) have been much more performant than the RTG designs

*I spent part of my career working on these devices and saw many of them running in labs


Checks out - I didn't realize we actually did fission... in... spaaaaace!

Unlikely. Much easier to just connect the sensor to the main power supply via a wire.


RTGs[0] use the thermoelectric effect to generate electricity from the decay heat of radioactive isotopes. This new material would allow better power generation using RTGs.

Like what Amazon is doing with their AWS toolset? (current S3 troubles notwithstanding) Think you can do better? Want to get in on the ground floor of that effort?

If you can get over the fact that we’re not a very popular topic at dinner parties then we can make it worth your while and challenge your ability to channel and organize data streams for ourselves and our partners.

Comcast is -very- motivated when it comes to putting together tools and environments that leverage the literal crap-ton of data (yes, thats an official SI unit) that arrives on our doorstep every second. We’re not stuck on must-have tools, languages, or mindsets since we know that the most effective ones will eventually show themselves regardless. The same applies to the likes of yourself. We’re less interested in languages you code in, if you’re competent then you’ll be adaptable regardless.

Now, that said, our current toolsets include: Spark, Terraform, Ansible, Genie, Docker, Kubernetes, Kafka, Java, Scala, and a few others.

Tell us what drives you, what you’re passionate about.

Ping me at: br24 at comcast dot net I can tell you anything you need to know.

We’re pulling data from over 20M machines in real-time, think you can help us get it under control? We’ve barely scratched the surface of whats possible and with the full AWS toolset at our disposal there isn’t much we can’t tackle. That is, not without your help.

So, if you’re seeking challenges just beyond your abilities with a passion for best practices, we’ve got the stability you want and the guarantee that your kids will still recognize you after you join. Heck, if they watch TV they’re already part of our beta testing programs! Unlike some of the other well-intentioned startups here we don’t provide cots under your desk, we work reasonable hours. With a monitor on your desk you can even watch HouseHunters/GameOfThrones/Spongebob until your eyes fall out.

You’ll be working with Kinesis and other data streams to syndicate a metric crap-ton of data (yes, thats a real SI unit) to visualize and glean insights across the whole swath of TV culture.

Send me links to your projects, something you're excited about.

Relevant search bait: Java, Scala, Flume, Kafka, Kinesis, AWS, Spark, ZooKeeper, Storm, Docker, Avro
