Let me start off by explaining what condensers are: A condenser is basically an enormous chest made of diamonds and obsidian which can be surrounded by collectors and relays in order to convert light energy into EMC, and EMC into matter. EMC is the value of matter, for example, dirt is 1 EMC, diamonds are 8,192 EMC, tungsten is twice that amount, dark matter is 17 diamonds a piece, and red matter is 57 diamonds a piece. Now that we've put things into perspective, allow me to elaborate on the generation of matter, a full blown energy flower (a mixture of red matter relays and red matter collectors) can produce about 20 stacks of diamonds in 12 hours, however; take into account that it takes roughly around 2160 diamonds to make one of these. Also, twenty stacks of diamonds is barely anything in terms of Equivalent Exchange, where every item is extremely expensive and requires vast amounts of work.
Condensers are an essential part of Equivalent Exchange and not having them is an extreme pain as the efficiency of the process is decreased tenfold, since 4 collectors around a chest is the closest you can get to an energy flower, which is about 8 times as efficient as the former.
Wataki has allowed us to have a vote on whether or not condensers should be banned from the server.
TL;DR: Read the damn post, you lazy fuck.
