Every year divisible by four with remainder one, adventurous geeks hold an outdoor festival in the Netherlands. This year, about 6000 people are expected to attend a long weekend.

Among them will be a group of experimenters who will be testing a 42 volt direct current grid. Specifically, a cluster of tents within the festival will receive approximately 50 × 4 Amperé supplies and 8 × 16 Amperé supplies. Hopefully, this will be run by solar power but there will also be a backup generator. Switching a high load of direct current is more complicated than alternating current and losses around the example MOSFET circuit are expected to be less than 0.2W per junction. Although people are expected to bring together previously untested circuitry, it is hoped that pieces of the project will inspire multiple direct current grids in more permanent locations.

Hopefully, electrocution or voltage drop doesn't halt electrical distribution at the festival.

  Firstly, SI units are not capitalised[1]. Secondly, the unit is the unit, the person is the person, one is an English word, the other is a French name, the exact rendering of the French name is now irrelevant to the spelling of the English word. Thirdly, Ampere the person never had an acute accent anywhere - he had a grave accent on his middle vowel[2] (which is preserved in the pronounciation, at least in English).

  ...when written out completely.
  When abbreviated, however, they are capitalized.

  Consistency is for small minds, apparently.
