They would melt, but we do also have gamma voltaics which can use the gamma radiation from fission and fusion to generate electricity they just have an atrocious efficiency

Supercritical CO2 has been looked at a lot for the Brayton cycle which can get 50% efficiency compared to steam that generally caps out around 34%
The US and china both published studies talking about a brayton turbine but to my knowledge no commercial plants running off of it have been built yet

My 3 mile bike ride takes 2 minutes longer door to door than driving.
As has been repeated a few hundred times in this thread already, the part that makes it takes so long is car centric infrastructure. If you live in suburbia where you have a population density of 1k/mi2 (400/km2) you will have to travel a much more significant distance than if you live in a place that has 9k/mi2 (3500/km2)
Then with less car centric infrastructure the benefit of having parking right next to work starts to go away and the extra space can be used to shorten commutes as well

8·1 month agoTaxes is a combination of a 3rd grade reading level and 3rd grade arithmetic. It literally directs you where to get the values for each box and the most complicated math you have to do is basic addition, subtraction, or multiplication.
Teaching a person how to fill out a 1040 is a complete waste of time especially considering they likely won’t need to fill one out for several years and teaching people all the obscure possible forms is pointless as the tax code changes and it’s only applicable to a small fraction of the class and likely not for 5+ years

91·1 month agoIt shows an absolute callousness to the murder of 3 people, wrongfully implies the killer had some affiliation with the state, and makes you sound like a cunt
For advice on not being a callous cunt, when 3 people are murdered how about not using that as a soapbox to insult where they lived…
So why not keep time as a constant and if individual places want to change times they can do that
Even just single states can have vastly different sunrise and sunset times and changing 300m people’s schedules so that a few people can have a few extra minutes of sun in the morning for part of the year seems absolutely ridiculous
A local school district could very easily do a 1 hour shift as the sunrise gets later so that it properly aligns with their local school pickup times

So take some boron-10 put it in a neutron flux and you get helium. This is being done in nearly every nuclear power plant in the world every second

2·2 months agoYou need to lower your expectations, we aren’t going to go from the current system to immediately jailing billionaires for the crime of being rich.
Small incremental changes are more realistic and as long as we keep moving forward, that is progress. If you frown upon all progress because it doesn’t fix every problem all at once then we just won’t get any progress

science@lemmy.world•Drinking 2-3 cups of coffee a day tied to lower dementia riskEnglish
1·2 months agoBut why wasn’t this compared to caffiene from sources like energy drinks? Then even as a control why wasn’t other stimulants like adderal asked about?
Claiming it’s caffiene by comparing to decaf coffee is dubious to me personally because what kind of people drink decaf? Usually people who were long time coffee drinkers who had to stop for some reason
So is coffee and tea neuroprotective or is caffiene sensitivity a risk factor for dementia?
Is caffiene neuroprotective or is it all stimulants?
The article itself ends in the classic we need to investigate more but that’s clearly not the conclusion most people who discuss this are going to be talking about for the next few months

Black tea is generally over 5mg/floz
Are you basing this on how alert you feel or do you have some very weak tea and some super strong decaf?

You know they give nitrous to people intentionally during surgery and dental work?
Like you can wear an O2 monitor while you take a whip it and track your oxygen level and I have never seen it drop below 85% which is the level where they start to get concerned in a hospital
Taking opiates cause you to just stop breathing and I had to have a breathing device following a surgery because my O2 levels couldn’t be maintained… and people get prescribed opiates and take them at home all the time with no monitoring



But not everyone agrees on which colors go together and which clash
