I would think that you could leave a Rosetta Stone with directions on how the data is stored and read. It wouldn’t take much, I think. “These glass things contain information, here’s how it is encoded. Here’s the requirements on reading these”. You could start off simple and have a rudimentary one that can be deciphered by hand that describes how to make a device that can quickly pull information from a few others that give directions on how to build another device to read the high capacity ones. You don’t need a specific filesystem or computer to read it, you just need to know how to decipher it and that it IS data stored in a certain way, not just cool looking glass art.

You are correct, the person you’re responding to is jumping to conclusions with no evidence.

There’s nothing in the article stating such. Just that one of the women had become fearful of the world because of COVID.

Methane is produced by methanogens in landfills, methane is not really part of the carbon cycle. The cycle itself isn’t self contained, so all the carbon dioxide and methane join all the rest in the atmosphere. We want to reduce any greenhouse gas sources as much as possible, whether it’s “carbon neutral” or not.

They can’t just use any type of sand for construction, beach sand is out of the question as it’s not rough enough. It’s coming to the point that it’s hard to find sources of sand that don’t have negative ecological impacts, so replacing that component with something else is a good idea.

I’d be willing to guess that they already tested using bio char as a replacement and saw that it worked well in concrete, then started looking at waste sources of starting material that had sandy texture, then boom coffee grounds.

No, 4kwh is about the daily amount of sun hitting 1 square meter. Solar panels can capture about 20% of that
