  • I'm call BS. Titanium isn't really very strong (about the same as copper when pure, while specialist Ti alloys are about halfway between aluminium and generic steel). People use titanium when they want something metal which is pretty strong but very lightweight. As an aside, it has pretty meh ductility for a metal and would make a poor bulletproof material, so David Guetta got that wrong too

  • Vegans of Lemmy, would you eat lab-grown meat?
  • The energy for lab grown meat has to come from somewhere - thermodynamics is always king. You can provide it via sugars/carbohydrates which the cells can motabolise, but you've got to put energy into making the sugar/carbs which is easiest by just growing some sugarcane/potatoes/etc. There's more steps for meat vs plant and it's very unlikely you can make 100 calories of lab meat with lower total system energy input than 100 calories of plant matter. (N.B., I'm a chemist, not a astronomical biologist, so if an expert refutes me and my assumptions, Place more trust in them)

  • Longi claims world record-breaking 34.6% efficiency for perovskite-silicon tandem solar cell
  • I dont know this work, but have had a hand in some solar cell research (nanomaterials development), so can give a little context. This is a "one off" in so much as it will be centimeters sized lab based sample, although it has been repearedto verify. The current cost difference is astronomical versus mainstream (silicon) panels, but that's typical of new discoveries. To be more exact, this is TRL 4 (technology readiness level 4) which is a scale that goes up to 9. Things only start getting cheap as you get towards the top. As for what the expected price of these materials would be, we don't usually know for sure, although as this is a tandem cell it must be more expensive than mainstream as it literally builds a perovskite cell on top of a silicon one. They will never be used for mainstream - this is a specialist material.

    The perovskite itself might make it as a general use solar cell. They have good efficiencies and you don't have to make pure silicon (which is a bitch) and can in theory make them cheap and easy. As for time frame, I'm a bit of a skeptic it will ever be really used as there are a couple of issues this tech needs to address before it's viable (#1, they degrade in air and encapsulating them adds new issues) and we already build silicon factories so that is soooo cheap versus building new factories to make long-term-cheaper cells. Factories are expensive. But in theory, anyone could push it to the mainstream within a decade.

  • The first default (player controlled) team in Worms on PSX was called "1 UP", with the 4 worms being Ginger, Smidge, Fluff, and Dodger. My sister used to kill smidge in the first round so often it became a bit of a running joke and I adopted it as a screen name. Unfortunately, so did others in the early Internet days, so I went 1337 Sp33k and tweaked it to sm1dger, which I've kept for what must be 20 years or so

  • You are diagnosed with cancer but have no money for treatment. You've no option but to steal the money somehow. What's your plan?
  • The money is a means to an end. It would be more efficient to steal the drugs themselves. As a first guess, threaten a doctor to steal the drugs and write out a detailed rota of what to take and when for you. Depending on the means used to coerce, leave the country afterwards. Or just live in a country with socialised healthcare

  • ‘Baldur’s Gate 3’ Prepared for 100k Concurrent Players, They’ve Gotten 700K
  • If you're unsure if it will be for you, pick up divinity original sin 2, same maker and very similar style, but (a) without the d&d license and (b) will cost much much less. Both BG3 and DOS2 are incredible games which you can easily pour a hundred hours into

  • If you delete comments, they still exist (but are hidden from the public) so reddit can still sell the content/conversation to 3rd parties, eg for training language models. If you edit the comments first, it makes the conversation nonsensical and reddits "product" is less valuable

  • With all this talk about sync's pricing...
  • It's also possible to use the free version and just deal with ads. If you want lemmy to thrive, then sync is exactly the sort of thing we need (it's the only reason I'm here after the final death of RIF)
