Engineers At MIT And The National Renewable Energy Laboratory (NREL) Have Designed A Heat Engine With

Engineers have developed a heat engine with no moving parts that is as efficient as a steam turbine. The design could someday enable a fully decarbonized power grid, researchers say.

Engineers at MIT and the National Renewable Energy Laboratory (NREL) have designed a heat engine with no moving parts. Their new demonstrations show that it converts heat to electricity with over 40 percent efficiency – a performance better than that of traditional steam turbines.

The heat engine is a thermophotovoltaic (TPV) cell, similar to a solar panel’s photovoltaic cells, that passively captures high-energy photons from a white-hot heat source and converts them into electricity. The team’s design can generate electricity from a heat source of between 1,900 to 2,400 degrees Celsius, or up to about 4,300 degrees Fahrenheit.

The researchers plan to incorporate the TPV cell into a grid-scale thermal battery. The system would absorb excess energy from renewable sources such as the sun and store that energy in heavily insulated banks of hot graphite. When the energy is needed, such as on overcast days, TPV cells would convert the heat into electricity, and dispatch the energy to a power grid.

With the new TPV cell, the team has now successfully demonstrated the main parts of the system in separate, small-scale experiments. They are working to integrate the parts to demonstrate a fully operational system. From there, they hope to scale up the system to replace fossil-fuel-driven power plants and enable a fully decarbonized power grid, supplied entirely by renewable energy.

adhd “get shit done” hacks i’ve found so far

1. the Event

have something scheduled for the day, be it a class, club meeting, shift at work, going to a friend’s, whatever. you must get shit done before the Event. i’ve also done it where the event is my roommates coming home, and I tell them to ask me what i did so i feel like I have to do shit. get creative.

2. exist in a space in which you can easily hyper-focus

pretty obvious, go to a cafe, library, friend’s house, whatever works for you, and do your thing. also! cleaning your house can really help with motivation and focusing, so that too. 

3. “multitask”

this one took me a while to figure out. make your brain think you are “multitasking” so getting stuff done is less difficult. ie put the laundry in, meanwhile do the dishes, wipe the counters, vacuum. or put it one of those microwave meals in the oven instead, then you have a reward waiting for you after an hour of studying. for some reason, getting tasks done as a pastime until something else is done makes it way easier to do them

Wylan: So he called you an investment?

Inej: Yup.

Wylan: That's bad. Even for Kaz.

Inej: At least he didn't call my face stupid.

Nina: Burn!

Wylan: For the last time, HE SAID HE LIKED IT.

.

Jesper: And then I said I liked his stupid face.

Matthias and Kaz, aggressively taking notes: Interesting.

What are your thoughts on this?

Interestingly Richard Fenyman remarked the occurence of the Fibonacci sequence and the 'golden angle' (primary part of the fine structure constant) in his work on quantum mechanics. And according to my information progression stuff, yes it wouldn't surprise me that this elementary principle of 'self-replication" might be one of the fundamental underlying patterns.

This is a plain idea I head: dividing the Fibonacci numbers: Larger Fib. number/smaller Fib. number (like 3/2 or 8/5) results in a damped wave alterating around large PHI (1.618...) and smaller number/larger number (like 2/3 or 5/8) results in a damped wave around small phi (0.618...) in the pic I just combined them in a strange axes system - and it's fun to imagine what would happen if you cause torsion and skews upon that visualized model:

Interestingly, the Fibonacci numbers also exist in a certain interference-diffraction pattern/fourier transform, Fraunhofer diffraction to be more concrete.

Made a post about that some days ago(or was it weeks already?): (Although the stretched x-axis is not really required)

In concrete, these describe position probabilities of superposed/entangled elementary particles. It is the pattern recognized in the double slit experiement.

Secondly, as the standard distribution also has connections to the concept of Pascal's triangle, in which the pattern of the fibonacci numbers are also omni-present, this would hint even more on the fundamentality of this logical sequence. But what is it concretely interpreted? In a different approach of interpretation, the Fibonacci sequence can be ragarded as a simple replication sequence, of continuing certain progression patterns, somewhat, yes it sounds silly: "Past+Present=Future, and Present=Past+more previous past", although it is far too simplified if taken literally. In a very rough pattern, this might be correct. But the exact details are generated by that same process just interacting with uncountable similar parallel versions of it (these are what i regarded as butterfly clones in my thesis)- chaos theorists might call them "feedback loops", and you can imagine it as a ball of uncountable worms knotting each other...

Facts

I’m not seeing nearly enough people talk about Phastos, our first openly gay character in the mcu, with a husband, both POC, and their son, Jack.

Y’all be writing 7484838 page fanfics about SamBucky, try to cancel Anthony Mackie after he tells you to stop fetishizing gay relationships but once there is an actually openly gay character y’all sleep on him.
