Reply to New innovation leads to environmentally friendly solar cells by gold79

>“One of the biggest drawbacks of using perovskite solar cells is
their impact on the environment. By enabling zinc and other non-toxic
metals to be used in the capping layer, our innovation potentially
solves a major obstacle that prevents the widespread use of perovskite
solar cells,” explained Dr Ye Senyun, research fellow from the NTU,
School of Physical and Mathematical Sciences, a lead researcher of the
study.

Hm, doesn't this just delay the environmental impact or slow it down?

LNER

Southeastern

Northern

Welsh and Borders, now TFW

All nationalised since that article was produced. That's 6 operators out of 28 or 21%

I think 21% is enough to say that the article is now factually inaccurate.

Best not to talk bollocks about something you don't understand.

Reply to Scientists find a way to suck up carbon pollution, turn it into baking soda and store it in the oceans by tottocotunio

Edit: Plant a tree or throw some local seedbombs!

This comes up pretty often in r/ClimateOffensive and similar subreddits. I have had colleagues work on similar projects. It's great that people can do work like this! There will always be a net loss of energy and increase in carbon in this system however, as subtly noted in the article.

Burn CxHxOx creating CO2 -> use energy to capture the CO2 -> put the CO2 somewhere. The only issue is the CO2 captured with the energy produced will always be less than the CO2 created.

This technology is important long term, once fusion is viable commercially, but currently it's more of a distraction and creates CO2 while using crucial grant money and scientific resources.

My dream is a politician comes up and says “Yo we’re doing an interstate rail system” and just opens fire about having more jobs easily accessible to people, the trillions of dollars that will be injected into the economy paying construction workers and journeyman, and how states will directly benefit from boosted tourism on the first guy that tries to talk against it.
