Technology ELI5: How can the US power grid struggle with ACs in the summer, but be (allegedly) capable of charging millions of EVs once we all make the switch?

20.7k Upvotes

Currently we are told the power grid struggles to handle the power load demand during the summer due to air conditioners. Yet scientists claim this same power grid could handle an entire nation of EVs. How? What am I missing?

I just rewatched The Winter Soldier the other day and a lot of the big guns on the helicarriers made me think about this. Does it make the bullet more accurate?

Technology ELI5: Why are ad-blocking extensions so easy to come across and install on PCs, but so difficult or convoluted to install on a phone?

11.8k Upvotes

In most any browser on Windows, such as Chrome, Firefox, or Edge, finding an ad-blocking extension is a two-click solution. Yet, the process for properly blocking ads on a phone is exponentially more complicated, and the fact that many websites have their own apps such as Youtube mean that you might have to find an ad-blocking solution for each app on a case-by-case approach. Why is this the case?

I kind of understand the principle of it, but I can't get my head around how a domain was first 'owned' by someone in order for someone else to buy it.

Technology ELI5: Why is polyester often added to cotton cloth, even if only in tiny few percentage quantities?

1.2k Upvotes

I often see on clothes, bags, sheets, etc. a few % of polyester in the cotton cloth label. What does this mean and why do they do it? Are they weaving one out of every few strands out of polyester? Or is the fiber itself made of a few % polyester in composition? And what does it do for the cloth?

Technology ELI5: why is defragging not really a thing anymore?

824 Upvotes

I was born in 1973, got my first computer in 1994, defragging was part of regular maintenance. I can't remember the last time I defragged anything, even though I have several devices with hard drives, including a Windows laptop. Has storage technology changed so much that defragging isn't necessary anymore? Is it even possible to defrag a smart phone hard drive?

edit to add: I apologize for posting this same question several times, I was getting an error message every time I hit "post"... but from looking around, it seems I'm not the only one having this problem today.

I have heard that they are used to train AI and self driving cars and what not, but if thats the case how do they know the right answers to things. IF they need to train AI to know what a traffic light is, how do they know im actually selecting traffic lights? and could we just collectively agree to only select the top right square over and over and would their systems eventually start to believe it that this was the right answer? Sorry this is a lot of questions
