You would likely start from the center of your galaxy, then pick a culturally relevant star near the outskirts, in our case Sol, and call that, well, something (Solbound?) Then work your right angles from there. You could pick other cultural stars in the other directions too.
Most galaxies are pretty flat, so you'd probably have to reference a conveniently positioned other galaxy for your up and down.
I wear a baseball style cap every day to protect my long hair during my day job in the HVAC industry. I stuff it up in there
Idk, words are tools as well. Right now it's being used to wake people up to the fact that republican policies are very invasive, harmful, and unpopular. I get being uncomfortable, but this is just language being language. And it's overall going to be beneficial.
Maybe this will end deforestation
Seems like this map accurately displays the poles at the expense of the continents
Getting a true fractal tattoo would take forever
Beverly Craig of the Massachusetts Clean Energy Center discusses what passive house building principles entail, the benefits they generate for building occupants and the grid, and what it would take to persuade more US builders and policymakers to adopt them.
Passive homes (a building designed for minimum losses on heating and cooling) are cheaper and easier to construct than you might think. In fact, it's nearly the default code in Massachusetts.
Being publicly opposed to assassination of your own government leaders is hardly sympathy. It comes down to some pretty basic principles of "don't kill" and "don't give the FBI a reason to knock on my door".
What jack black said is the celebrity equivalent of "lets be careful of what we say online"
There are 2 types of real carbon credits, easy credits and hard credits. The easy ones are cheap things like planting trees and efficiency programs, the hard credits are expensive, carbon capture tech that we haven't perfected and will always be costly.
Poor countries are attracted to the idea of selling their cheaply attained credits for money today. And why wouldn't they? They are indebted and struggling. But it's going to fuck them over in the future when they need credits for their own carbon accounting and they're out of easy credits to make.
No hate or judgment here, it's just the next steps in how global imperialism will continue to fuck over these countries
Puerto Rico has to be one of the worst victims of the industry with also the least recourse due to a lack of statehood
Probably realized he could cut server overhead by 40% this way
Just because our side isn't as popular as you'd like doesn't mean we don't have democracy. Now what we do have is a flawed system with lots of mechanisms for a minority party to grind the gears to a halt, and incredibly low voter turnout especially among the far left.
The only way out is to vote in a supermajority of reps who want to fix the system. So vote blue this year, and start building an electable coalition for next cycle. Don't just stand there, do something
It would be incredibly stupid to switch out Biden now. Who would we replace him with thar we're so sure would beat Trump with this little time left until the election? If the plan was ever going to be to replace Biden, he would have had to step down at least 5 months ago.
CEO Kyle Clark of BETA Technologies walks us through the details of how to design, build, and operate electric planes — first for relatively short light-cargo flights, but eventually, he says, for all of aviation. I loved this conversation so much.
Electric vehicles that can take off and land vertically, but then fly like a plane, are already being sold and used by hospitals and shipping companies. Equipped to move up to 6 passengers or 2 pilots and 3 pallets, its a small yet versatile tool. These vehicles have 5 batteries that give it a range of over 350 miles using current battery technology, though the batteries are intended to be swapped over the life of the aircraft, much like the engine of a traditional aircraft, however, future batteries could feature improvements, meaning the vehicle gets better over time. The redundancy that Electric motors allow more easily than mechanical motors means this aircraft is far safer than anything else in the air.

California electricity guru Lorenzo Kristov shares his vision of a just, democratic, “bottom-up” grid based in distributed local energy.
The energy system we have today does not match the solarpunk future we dream of. If we work towards the right energy system today, we may just have a solarpunk tomorrow
At long last, one of clean energy's OGs, Michael Liebreich, has come to Volts. He and I discuss his recent essays on five causes for pessimism about the net-zero transition, alongside five causes for optimism.
The take that struck me the most came towards the end. And it's that when you electrify, not only are you not burning fossil fuels to work your stove, but you're also not burning fossil fuels to power the drilling equipment, to ship the crude oil, to refine it, to pump it to your stove.
A large portion of our critical energy demand is just getting fossil fuel energy to its point of use, so small amounts of electrification and efficiency improvements at point of use have large impacts on the upstream emissions
Hardware and software improvements may enable geothermal heat pumps to be installed more quickly and less expensively, even in large commercial and industrial buildings in tight urban spaces. I talk it over with Joselyn Lai of Bedrock Energy.
David Roberts interviews a representative from the company that is making effective ground source heat pumps for large buildings. How they do it, ensure efficiency, and look to scale up the operation
Urbanists like to say that dense, walkable urban land use is a powerful climate tool. But what kind of emissions can urban land use really reduce? What is the scale here? I discuss it with the authors of a recent RMI report on the subject.

15 minute cities are great for a number of reasons, but are they really a good climate policy? David Roberts discusses with researchers Heather House and Rushad Nanavatty
I discuss the newly launched MethaneSAT — a satellite that can detect methane emissions on the ground — with Mark Brownstein of EDF. We cover how it came to be, its technical capacities, and the ways satellite detection might serve global efforts to reduce emissions.
The path to zero emissions requires household electrification. Go electric!
By entering some information about your home and appliances, they generate a basic plan for your next upgrades, including price estimates, available rebates, and estimated energy savings. Takes like 5 minutes, 10 minutes if you want to read all the details.
I don't want any lemmy.nsfw posts on my All tab. And there are so many instances
Making cement -- the most commonly used substance on Earth after water -- is responsible for 8% of global carbon emissions. It generates CO2 both through combustion of fossil fuels & through chemical processes. Sublime Systems thinks it has solved both sides of that equation. I talk with the CEO.
Climate Tech Reporter David Roberts discusses battery recycling with ceo of a company that is working on scaling up a newer fossil fuel free method of melting down and separating battery metals. This method has advantages of not burning up most of the valuables and sending them into the open atmosphere as well as not requiring a constant stream of harsh chemical feed, or having chemical waste.
Today his small scale plant is handling mostly the waste from faulty primary manufacturing, and is looking to scale up in time for the 2030 boom in lithium battery recycling.
A beautiful medieval sounding song features a wisened warrior recounting his regret. As a young man, a dragon plagued his lands, the beast with a forked tongue and breathe of fire, surely it must be slain. Before he goes, his father warns him to know his enemy well. He sneaks into the lair, kills the sleeping dragon, and looks across the room to see a baby dragon, and he realized that he killed the poor things loving parent who was just living it's life. He did not understand the enemy he just slew.
Now he listens to his own son talk of an enemy plaguing their lands, forked tongue and breath of fire, clearly a problem, but instead of a dragon, it's men of Muslim faith. The father begs his son to truly know his enemy before going to war.
The story in this song is simple and maybe heavy handed in its message, but beautiful none the less. I probably cried the first 20-30 times I listened to it. I will always love this song that teaches kindness and wisdom. If Songs with good storytelling get you everytime, you'll love it too.
Storing electricity as heat! It's so, uh, hot right now. I talk with the head of a company that makes a thermal battery that outputs either heat or electricity. It's one of my favorite technologies around -- super-geeked about this one.
Climate Tech Reporter David Roberts discusses heat battery with PV panels that can be used to heat up industrial processes, one of the hardest sectors to decarbonize
