I don't think you have anything to fix. Learning is its own reward. Keep doing what you've been doing and know that you're getting out of it exactly what you need.


Kudos on getting your project from conception to the finish line!

The concept of having to interact with the natural world before being allowed to interact with the social media world is interesting and this is perhaps the most interesting implementation of that.

Personally I find it's rewarding to flex the "self restraint muscle" by stopping myself from doomscrolling rather than relying on technology to do that for me.


> The applications of this technology in this particular space seem limited

Thermoelectric generators have applications in basically any space where you're generating excess waste heat (and you're able to maintain a temperature gradient). Off the top of my head, industrial scale distillation, desalination, garbage incineration, high energy lasers and pyro/electrometallurgy. The advancement of the technology for the automotive space would really have served as a springboard to increase efficiency in other areas.

> thermoelectric generators are simply not efficient enough to adequately offset the heat energy losses in ICEs.

Any amount of waste heat that can be converted to electricity and used or stored is good. Why not try to get every last joule out of your fuel?

You're right that the technology has been inefficient. For typical ceramic thermoelectric generators the conversion ratio from heat to electricity is low, it only works if you can maintain a temperature gradient and you have to contend with self-heating, but addressing the inefficiencies is exactly what JPL would have been trying to do. You couldn't ask for a better partner to push the technology further.


YouTuber Benn Jordan would probably get a kick out of this. He's a major audiophile and did a series of ambisonic ambience.


Thanks, I think so too by the looks of his channel, I'll get in touch!


I was just thinking about this!


Another way to do this would be to make an app that uses positional information from the headphones and feeds the sound of your choice into a head related transfer function (HRTF) to give the illusion of spatial audio.


It'd be interesting to see an overlay showing images by their age.


"Skunk Works: A Personal Memoir of My Years at Lockheed" by Ben R. Rich and Leo Janos.

Details, among other things, the engineering challenges faced during the development of the F-117 Nighthawk and the SR-71 Blackbird.


An excellent read, no doubt. I've actually read it a couple of times. Ben Rich was a great writer.


Boy, I don't agree with that last. It's a pretty interesting book, but the writing is pedestrian and there are far too many asides and stories that detract from the main points. By way of contrast, I read it because it was recommended after I said I loved "The Soul of a New Machine" (Tracy Kidder), which really is an extremely well-written book, in the "every word counts" sense. "The Soul of a New Machine" is a book that a writer can appreciate for the writing.


you have a point. how about this. s/writer/storyteller/


It was written by Leo Janos, who also wrote Chuck Yeager's bio.


worth reading for rich's crazy jokes alone. the fact he is telling them to senior military brass in the context of negotiating his division's survival after kelly johnson's retirement makes them even funnier. my favorite - a boy comes home from school, finds his dad, and proudly declares "dad, i saved 25 cents by running alongside the bus instead of riding it!". the father shakes his head and replies sternly, "you fool, you should have run next to a taxi and saved five dollars"


Eh, for me those all weakened the book.


More aviation project books along those lines:

V-2 by walter dornberger - wartime engineering, rocket development

Gossamer odyssey - human powered aircraft, scrappy university project style engineering


Excellent book about the strength of a free market and the extreme damage government bureaucrats cause.


Maybe the footage from runway cameras was sequestered for internal review.


After all these years, have you ever wondered why zero footage of the SST that caught fire taking off have surfaced? Or even photos? That the only video of it was taken from a car on a nearby highway?

We all know the cockpit voice recorder exists and is essential for investigating a crash. I seriously doubt there are secret cameras recording the tarmac and it's all been hushed up. There are simply no cameras there.


How does hiding videos help anyone? It's not like the footage magicaly disappears when you show it to the public and investigators can't use it. We live in the digital era, it takes like 7 clicks to share the footage to the entire world. Are pilots and engineers around the world gonna be better at preventing this type of disaster if we all make sure they never ever get to see it?


Pilots and engineers will be better at preventing this type of disastr after and only after a review has been done. Just like a trial, seeing footage earlier and in a different venue than the "review room" can color opinions inappripriately and actually hender the search for truth.


Wouldn't that apply to any initial evidence?


I've watched nearly all the "Aviation Disasters" episodes. I don't recall any footage other than incidental amateur footage. The investigators spend a lot of time even figuring out where on the runway the various planes were, implying there was no footage.


Do something positive for the environment, like supporting the development of cheap sustainable plant-based packaging.
