AI Thread Summary
The discussion revolves around the costs associated with liquid helium and liquid nitrogen. Liquid nitrogen is significantly cheaper, generally around ten cents per gallon, but this price is typically applicable to high-volume manufacturing rather than small purchases. Liquid helium costs more, although specific pricing details for helium are not provided. The conversation also touches on the impracticality of purchasing small quantities of these substances, as they are usually acquired in bulk for industrial or research purposes. Additionally, the mention of quantum dots indicates a focus on advanced materials, though they are not directly available for purchase.

No, I'm not thinking of buying one/any, but how much does one cost?, any type. Plus, how much do the two commonmost types of helium in liquid form, and/or liquid nitrogen, cost per gallon? I know liquid nitrogen is cheaper... a lot.

...If I were to not buy in bulk.

A quantum dot isn't really something you can buy. Nitrogen is on the order of a dime a gallon, but that's high volume manufacuring prices. You can't really just go buy 10 gal of it.

No, I ment like at MIT, the cost of constructing one the cost of how much helium they use...

I know a guy, he had ohh... actually about 10 gallons of it in a tank in his classroom.

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
