Dye-sensitised solar cells are a type of photovoltaic device which uses a colourful dye to absorb light and cause an electric current, instead of the silicon semiconductors which most regular solar cells use.
It works because chemically, colour is caused by light being absorbed by molecules, which makes their electrons jump about. Dyes used to make solar cells absorb light strongly, and completely give up those electrons, which causes an electric current to flow.
So it turns out, because red grapes are full of molecules which are very good at absorbing light, you can make a working dye-sensitised solar cell using port wine instead of one of the fancy dyes which are normally used.
And honestly, I just thought that was really cool and worth sharing! ☀️

. @warpgate9 and I run a community #Minecraft server, http://indiesquish.com . It's family-friendly, we have teeny tiny childlings playing there with their parents/siblings, and it's LGBTQ friendly and autism friendly (and just generally fosters a community of respect). It's a very kind, warm environment to play in. If you play Minecraft and want an inclusive and welcoming server to play on, check us out. :)
Y'know if 1 person just 1 person blocks bigots, folk might think she's really sick and they won't like er.
An if 2 do it, folk might think they're both weirdos and they won't like either of 'em.
An if 3 do it; can you imagine 3 of us sittin down blocking bigots and carryin on? Folk might think its an organization.
An can you imagine 50 people a day? I say 50 people a day sittin down blockin bigots and carryin on?
How should academics cite their transgender colleagues’ work produced under past identities? https://www.chronicle.com/article/How-Should-Professors-Cite/246675 has more questions than answers but the advice at the end (when in doubt, ask them what they prefer) seems like a good idea.
