Climate change 

i used to be really into having the newest computer gadget. now i use refurbished hardware. it's so much cheaper. it lasts. it reduces landfill waste. it's great, and i don't really feel like i am missing out on much tech-wise.

here are some tips if you need tech stuff but don't want to spend a lot of money, support horrible companies, and such (1/n)

Why are people posting tons of retweets on mastodon? It's like dumping stuff without thinking in a complete different environment. I'd really like an option that filters retweets... 🧘‍♂️

Mein Freitagnachmittag- Projekt: einen neuen Lüfter in meinen Laptop einbauen 🔥. Eines muss man diesem Dell Latitude E7240 ja lassen; man kommt super an alles ran und kann sehr viel austauschen

Is it wrong to shame people for their SUVs? 🤔

What's the best for ? I use my iPad only for music making and I'm not an Apple fan. So I'm not really interested in investing a lot of time in that walled garden to try stuff. I'm thankful for any suggestion. 👍

The Biosphere

This incredibly thin layer of air, water, and soil that covers the surface of the Earth is the human habitat, the only place in the universe where we can survive. If we ruin it, we join the dinosaurs.

Interesting #conceptual design making agriculture in "hot and dry coastal regions" all the more efficient...

It a seawater-powered #solar #greenhouse and it's engineered to work with the variety of climatological region that has easy access to salt water, but maybe not fresh water... yet still do water-intensive agriculture.

"A #seawater greenhouse produces crops year-round in hot dry areas using only seawater and sunlight. Tomatoes, cucumbers, peppers, lettuce, strawberries, herbs—anything that can be grown in traditional greenhouses—can be grown in seawater greenhouses. The award-winning technology, invented by Seawater Greenhouse Ltd. founder Charlie Paton, was inspired by the natural water cycle where seawater heated by the sun evaporates, cools to form clouds, and returns to earth as precipitation."

"The idea behind the process is simple. It combines two unlimited resources - sunlight and seawater - to provide ideal growing conditions for crops in hot, arid environments.

The innovation [uses] the cooling and humidifying power of water vapor produced from evaporating salt water. Using modeling and simulation techniques developed in collaboration with our partners at Aston University, we are able to process local climate data to predict greenhouse performance and inform the design. The combined effect of reducing temperature and increasing humidity, together with providing a protected environment for crops, results in up to 90% reduction in Evapotranspiration. This to greatly reduced irrigation requirements, which can be provided by desalination, and improved growing conditions."
