Yeah I know. I was taught it was 110/220 also. When I saw 120/240 one day I was like WTF is this? Checked it out and it just happened to be fact. Funny how it seemed to slip by me for so long.
I was taking to my girl the other day about someone being involved in some company and she was like, "I never heard that before." So I googled it and found out that they never had anything to do with each other. I don't know why that info stuck with me but it was totally wrong! Makes me wonder what else I've "learned" that was totally false.

Power companies have multiple meters to check back on how much power is running into a neighborhood vs. how much the summed readings off of all the house meters and begin to narrow down who is stealing power.
240V is more efficient over long wire lengths, and is explained by the power loss equation P=(I^2)R, where I is the current (Amps), R is the resistance (constant for same gauge and length wire), and P is the lost power that was converted to heat.
240V needs a weird plug because it has double the arc length...so wiring and circuitry to handle only 120V power can result in a 240V electrical arc across wires, which on a 20 amp circuit could result in 4800W of electricity released all at once. The conductor spacing must be doubled when using 240V service, therefore they make it hard for someone to plug a 120V appliance into a 240V plug 
As for wiring for residential using 240V...good luck, thats beyond my knowledge base...
