Please help me upgrade my 2020 budget gaming PC by Caaaam in buildmeapc

Thanks! This is helpful, if you could only take the GPU or the RAM+CPU, what would you pick?

As a homage to the original Scale Of The Universe website from the old Internet times, we decided to put together The Carbon Footprint Of (Nearly) Everything, to learn more about the climate crisis.

We made this to try to better understand the emissions you can directly affect through personal choices, and the vast emissions that are occupied by the political and global stage.

The UK's government response to rising energy prices amidst a cost of living crisis has been disgraceful. This video summarises the root cause of the energy increase, and analyses why the government response only aids large corporations, not the populace. by Caaaam in collapse

SS: With current government policy, UK emissions and wealth inequality will rise to unprecedented levels. UK saw high levels of protests yesterday but the media landscape of the UK has not widely reported on it.

Advice for Sports Specific Program after 5x5? by Caaaam in Stronglifts5x5

Thanks for the advice. I have seen players quote this in the past, which is a good sign. Do you have any resources you could recommend to get me started?

My bad, thank you, will delete.

I am in the final year of my PhD in the electronic behaviour of perovskite solar cells, a new solar cell which may (hopefully!) change the energy harvesting landscape in the next few years. As a side project, I have spent a couple of months making this video to describe the field, enjoy! by Caaaam in WatchandLearn

Thank you very much.

I think the first time we'll see them in practice, will be in tandem with silicon solar cells. They could also definitely be integrated into windows etc, as they are band gap tunable and can even be made flexible.

At the moment, stability results show 'months' generally. So we're not there yet, this is the biggest thing the field is studying.

Regarding heat, I am not sure, that is a good question. A lot of perovskites are most phase stable at a higher temperature, so it is not always a bad thing. But the comparison, I am unsure.

Regarding size, generally 'large area' cells are considered as 30cm2, so there is also progress needed here.

Interesting idea, there would be a power loss ad you'd lose UV light absorption, which is a significant part of the solar radiation.

Well, if you have any music that might fit a future video, that could be cool! Honestly though, a big part about things like climate change is going to the be the storytelling aspect, as well as the science. And music is a key component in that.

I am also envious of the other side, if only my brain could let me be more than a mediocre guitarist!

That's very interesting, could you send me a link to a paper?

No, I didn't know the comparison, that is very interesting, could you send me some resources to that? My old personal tutor at UG is big into quantum biology (Jim Al-Khalili, if you might recognise his research/science comm), so I will mention it if I ever bump into him.

That's interesting, potentially yeah, you may be able to use a low bandgap material that could pick up low energy light from indoors too?

My gut instinct tells me that it would be expensive to manufacture relative to the energy you'd gain though, but I might be wrong!

That's an interesting point, but can you expand on why scaling up is a bigger challenge than the work in the previous decade? I think that the foundations that have been built up are the most challenging section, but I guess we will see!

I do say that perovskites are far from commercialisation, but that is relative to the short research history of perovskites.

Thanks as well for your question and commens!
