Those numbers are for some very specific substances (which are also bad, nobody's contesting that), but not for CO2-equivalent emissions. It's the same kind of dumb number as that cloth bag reuse count vs plastic. Technically true

The Hindenburg carried around 200k m³ of hydrogen, or 18,000kg, storing 2.54 PJ of energy, or equivalent to 56,400 kg of jet fuel. A 747 can carry more than four times that (240k-ish); an A320 or 737 carries slightly more than half (25k-ish

1.) I think the OP was asking where they can find the insights obtained from this failed solar road test that would allow others to save money. Not general photovoltaics stuff. 2.) Angling solar panels is a more complex problem than you mig

Hard to tell what it's made of from the tiny image, but the cotton bags I know are 100% cotton (except for the print), like this: https://www.sinplastico.com/3742-large_default/organic-cotto... while canvas bags a

I don't think anybody's claiming that canvas bags are the answer. As you said, they contain a lot of plastic. The comment you replied to was about cotton bags, not canvas.

Turns out, because the 7100x number is based on a misunderstanding of the study it's from, and the actual number for climate impact is 52x: https://news.ycombinator.com/item?id=20581751

Thanks, that clears up a lot. According to that tweet thread, the number for climate impact is 52x. That's just one year of weekly use, which is a pretty realistic number.

Sorry, I edited my comment after/while you posted yours. The 7100x number is totally misleading because it's the maximum over all factors they considered, which turned out to be ozone depletion. But the study didn't communica

It's a false equivalence to claim that we can only care about one but not the other. Plastic pollution is threatening entire species and food chains. We need to tackle both problems simultaneously. Not to mention that everyone just ass

Galileo has not declared Full Operational Capability (scheduled for 2020), it's still in the Initial Services stage. It's a bit like complaining that a beta has bugs.

For me, the two choices in settings are "after two minutes" and "never", nothing in between. As you said, this is not a security setting, it's a storage space-saving setting.

That's nowhere near the value of bikes you'll find on the street in the Netherlands. The average resale value is going to be much much closer to 50€ than $1500.

You can enter something arbitrary (both for new mail and for replies). You can also configure sender identities you need repeatedly so you don't need to type them out. It's pretty neat.

Easy if you have an electric bike. Cargo bikes often have benches for the kids. They also have plenty of space for groceries. Very common in the Netherlands, and they come in electric versions as well for hillier areas or longer distances.
