Why is it that the number buttons on a computer and calculator are set up differently on a phone?

Why not keep them all in the same pattern instead of swapping the top and bottom lines over?

How do photochromatic glasses work?

My glasses go from clear to quite black in the cold, but don't work so well when it's hot.

Why can't you have a large lead plate array for a large lead acid battery?

The car battery shape and size is pretty standard these days, I know you can purchase smaller lead cell batteries but why not much larger ones?

For example I have an electric van with 24 separate batteries but it would seem to make sense to make a bigger battery(especially as the voltage is 48v i.e. 4 in series) is there any limitations on how big you could build a lead battery and if so why?

I understand that batteries have cells at 2.2v each so could you just create bigger cells(driving more amps) or would you need to have many separate cells?

I understand that obviously their are weight/manif issues, but if we could forget these for now.

alienware m17 electric shock?

Hello!

I got an alienware m17 laptop about a year ago. It is really fast and has great graphics. It is great for graphic intense gaming and it seriously rocks. I anyway took great care of it. Something weird happened 2 months ago. The power button gave a minor shock. I was suprised. I took out the plug and put it back again. Then it was fine.

 The next day it was again there, the same tingling sensation-no major shock, just tngling sensation. About a month back I put a transparent tape on it and it was fine. Later, The left speaker and the area above the speakers started giving a minor shock which used to go away after i turn it on for about 5 minutes. Since i live in India which is hot and humid, i sweat a lot and whenever my wrist used to touch that place i used to get shocked.

There are no electricity leaks from anywhere else. We have no carpets so it couldn't have been static electricity from my body. I always turn of the main power swith when the laptop is turned off.

Somebody please suggest me what to do about this problem.

How can I calculate the CO2-emmissions of my webpage?

My goal is to make my webpage (www.MyTree.TV) CO2-neutral! In order to reach this goal I intend to buy CO2-Certificates from www.newTree.org but the problem is that I don't know how to calculate the CO2-emissions of a webpage! The number of users is certainly important but if you consider just the electricity-consumption of a server it's not correct in my opinion. Does anyone know how to make a sound estimation?
