Answer to Question 1

Number of cells in series to produce 18 V = 18 V / 0.5 V = 36 cells in series

Number of 36 series cell groups that are in parallel to produce 4A = 4 A / 2 A = 2 sets of 36 series cells in parallel

Total = 2(36) = 72 cells

Answer to Question 2

Triple the total number of modular by adding 14 more parallel modules for a total of 21 modules.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
