It Sounds Like An Interesting And Ambitious Project. Does Anyone Know Is This The First Time We Have

It sounds like an interesting and ambitious project. Does anyone know is this the first time we have seen NASA pursue a major commercial aviation project instead of a space research project or space commerce project? One of the concerns with doing cool advanced electronics and electrical systems and also highly efficient electronic and electrical system is that they often require a expensive quantity rare earth metals which I believe at this time means people in other countries are exposed to dangerous and toxic working conditions mining and refining.

A Beginner’s Guide to Sustainable Aviation

Do you dream of catching a short flight between cities or journeying across the globe? The aviation industry currently makes up 2-3% of all carbon emissions, but the shift toward electric and hybrid aircraft will help tackle climate change and minimize the environmental impacts of commercial aviation.  

Sustainable flight will revolutionize the way we travel. From battery-powered aircraft that reduce fuel consumption, to new lightweight materials that can improve safety and efficiency during flight, here are a few important things to know about the world of sustainable aviation, and what it takes to make air travel cleaner and safer for our planet.

What is Electrified Aircraft Propulsion?

A Beginner’s Guide To Sustainable Aviation

Similar to electric or hybrid-electric cars, sustainable aircraft designs feature electric powertrain systems – the system of components that help propel an aircraft during flight – to help reduce fuel use and emissions. Electrified Aircraft Propulsion (EAP) systems let aircraft work using electric motors, and alternative fuels, rather than relying solely on traditional jet engines burning fossil fuels. At NASA, we’re developing innovative EAP technologies ranging from advanced electric machines designed to increase power and performance to new aircraft materials developed to minimize weight and reduce fuel usage.

What are the challenges with electrifying flight?

Unlike electric vehicles on the ground, electrified aircraft face greater challenges when managing weight and heat while they’re running. In order to ensure maximum efficiency and safety, aircraft components must be designed with minimal weight to help reduce the amount of drag slowing the plane down and causing excess fuel burn. Electrified aircraft must also have advanced thermal management systems to help transfer heat effectively, and ensure onboard systems are kept cool to avoid damage.  

Our research and development of EAP technologies offer innovative solutions to these challenges. Designed to keep weight at a minimum, aircraft components such as the High Efficiency Megawatt Motor feature advanced technology that enable increased power and efficiency with three times less heat loss and weight than traditional aircraft motors. New material technologies such as electrical insulation also help transport heat more effectively to minimize heat buildup and are made of lightweight materials to ensure efficiency at high altitudes.

What are the benefits of sustainable aviation?

A Beginner’s Guide To Sustainable Aviation

From an environmental perspective, aircraft electrification offers unique opportunities to lower global emissions and minimize reliance on fossil fuels. The introduction of hybrid- or fully electric aircraft will significantly reduce overall fuel consumption by generating power and thrust via electricity and electric motors. Lightweight EAP systems and components can also help improve aircraft efficiency and reduce fuel burn, while using non-conventional, alternative fuels can help reduce harmful emissions. From an economic standpoint, EAP technologies could help strengthen commercial airliner markets with aircraft designed for around 180 passengers. Green technologies can also benefit both airline companies and you when you fly by potentially reducing aircraft maintenance and in-flight energy costs, making air travel more affordable.   

When will sustainable flight take off?

A Beginner’s Guide To Sustainable Aviation

To help turn visions of eco-friendly air travel into reality, we’re teaming up with industry to test EAP technologies on aircraft and introduce them to the U.S. commercial aviation fleet no later than 2035.  

Under our Electrified Powertrain Flight Demonstration (EPFD) project, we will conduct ground and flight tests using existing aircraft modified with EAP systems to assist in transitioning these technologies into commercial products. Flight demonstrations will also enable us to identify key risks and barriers associated with integrating new EAP systems into commercial airliners and develop new standards for future EAP aircraft as they take to the skies within the next decade. 

There you have it: a quick glimpse into the world of sustainable aviation, and the shift towards keeping our skies cleaner and safer. As we embark on this journey, climb aboard and stay up to date on our latest technology developments and future flight demonstrations.

Their cells are literally slowly burning, they sustain themselves on a corrosive liquid, and they ingest poisons and toxins for fun, no to mention they can become several times stronger under stress. So no, we are **NOT** going to the human planet.

Thanks this looks helpful.

show, don't tell:

anticipation - bouncing legs - darting eyes - breathing deeply - useless / mindless tasks - eyes on the clock - checking and re-checking

frustration - grumbling - heavy footsteps - hot flush - narrowed eyes - pointing fingers - pacing / stomping

sadness - eyes filling up with tears - blinking quickly - hiccuped breaths - face turned away - red / burning cheeks - short sentences with gulps

happiness - smiling / cheeks hurting - animated - chest hurts from laughing - rapid movements - eye contact - quick speaking

boredom - complaining - sighing - grumbling - pacing - leg bouncing - picking at nails

fear - quick heartbeat - shaking / clammy hands - pinching self - tuck away - closing eyes - clenched hands

disappointment - no eye contact - hard swallow - clenched hands - tears, occasionally - mhm-hmm

tiredness - spacing out - eyes closing - nodding head absently - long sighs - no eye contact - grim smile

confidence - prolonged eye contact - appreciates instead of apologizing - active listening - shoulders back - micro reactions

god-made-it - My cool junk drawer

There's a new swarm of totally real ladies with empty blogs following me, and I'm blocking and reporting them left and right. If you are an actual human person with a brand new account trying to follow me, I urge you to please post *anything at all* on your blog so that when I go to check who the heck you are, I can tell you aren't just a bot-encrusted void. Just a simple "hello this is my lurker account I use to follow people" is enough.

One of the funny things about LotR is that almost every people in it professes to disbelieve in the supernatural, but because they live in a fantasy world their baseline for "natural" is so jacked up. The Rohirrim are like, yeah, there's a wizard in this tower and ancient tradition that we have no reason to doubt says this mountain is full of ghosts, but walking trees? Short people? I don't think so. Galadriel is like, "Listen I heard you describe what I do as magic and look I just gotta clear some things up, okay." Gondorians are like, yeah, of course the Enemy has spectres of men who lived long ago and never died and can now fly above us and incapacitate us with just their voices. This is just a fact of life, okay? But shut up about this magic weed that makes comatose people better. That's an old wives' tale. Royalty? Press X to doubt.

The people group in Tolkien's work who seem most receptive to magic and least restricted by their own notions of what it can do actually seem to be the hobbits. And they use it to avoid meeting people they don't want to talk to

Super excited about collections. I have only been here a couple of months but I was thinking about asking for something like this

Tumblr Hack Week, September 2022 Edition

It was Hack Week (more than just a day!) once again at Tumblr! A couple of times per year we slow down our normal work and spend a week working on whatever we want and see how far we can get with our hacks. The main star of the last Hack Week was the “Summon crab!” button, and we loved it so much that we rolled it out not just for April Fools this year, but we made it our first gift-able widget in TumblrMart!

Here are some of the projects that got made for this most recent Hack Week in September. Some of these things you may also end up seeing on the site…

Tumbeast Digital Pet

Ben worked on adding our friendly server room Tumbeasts to Tumblr as a cute little digital pet. You can feed them and play with them, and they poop and get unhappy and need tending, of course. Who wouldn’t want one of these to take care of every day on Tumblr, forever and ever?

Tumblr Blaze on TumblrMart

@adalpari added Tumblr Blaze as a gift-able item in TumblrMart, which would allow folks to buy Blaze "credits" for other people. Perfect for those times you see an amazing post on Tumblr that definitely deserves to be spread around, and you don’t mind throwing some money at letting that person have a chance to spread it via Blaze!

Tumblr Hack Week, September 2022 Edition

User Account Switcher

@yi5h hacked together an account switcher for the web, so that folks can log in to more than one Tumblr account and easily switch back and forth between them. Super handy if you have one account for your roleplaying character, and another for your Star Trek fandom discussions. Very useful!

Tumblr Hack Week, September 2022 Edition

Tumblr Collections

On web as well, João made a version of an idea that’s floated around many times, the idea of being able to organize posts on Tumblr into "collections" that can be named and shared. I think everyone would very much enjoy having a collection called "waves" that’s just soothing GIFs of ocean waves.

Tumblr Hack Week, September 2022 Edition

As always, stay tuned to the @changes blog to see if any of these hacks make it on Tumblr for real!

You’ve been trapped in this time loop for centuries, and an attempted “perfect run” decades in the making has failed to break the loop. Frustrated, you decide to go scorched earth on everyone and everything around you. The next day, to your horror, you wake up to find the loop has been broken.
