Ok, all of you guys are officially too dependent on Energy Collectors. It makes me glad that they are banned on the server I play on.
I have a MUCH better solution that does not involve Energy Collectors at all, and it starts with a single block of sand. (If you don't have sand, you could start by macerating some, even if the Philosopher's Stone is banned from environmental interaction.)
1. Build a Singularity Compressor.
2. Power it.
3. Put the Sand in the Compressor.
4. Take the Sandstone OUT of the Compresor.
5. Transmute the Sandstone into 4 Sand.
6. Repeat steps 3-5 until you have somewhere between 8 and 64 Sand.
7. Build this setup:
C W P O A
R -- S -- T
E F H,
Where C is a Singularity Compressor,
R is a retriever facing the Compressor with a piece of Sandstone in it,
E is an Energy Condenser with Sand as the target,
F is a Filter with a piece of Sand in it,
H is a Chest of any kind,
S is a Sorting Machine in All Stack Sequential with 1 Sand in one column, with White selected, and 3 Sand in another column with Orange selected,
P is a normal Pneumatic Tube,
W and O are Pneumatic Tubes painted White and Orange, respectively,
A is an Alchemical Chest with a Gem of Eternal Density, or another Energy Condenser (this is where the output will go)
T is a Timer set to the lowest interval,
and -- is Redstone or Red Alloy Wire.
In addition, Redstone should be placed on top of the Retriever and the Filter, connecting them to the Timer; The Retriever should be powered by Blue Alloy Wires or an RP Batbox directly; W, the White Pneumatic Tube, should in fact be placed above P at a right-angle to O, and then connected to the TOP of the Compressor by unpainted Pneumatic Tubes; and, optionally, a lever can be placed under the Compressor to put it in Standby Mode (so that it maintains its PSI even without Sand to process).
Although the startup may be slow, the system should reach a very fast pace in due time. If it is not fast enough, it can be expanded with only additional Compressors, Filters, and painted Pneumatic Tubes (columns should be added to the Sorting Machine and the numbers adjusted to match the amount of Sandstone put into H in a single pulse.
If you lack sufficient knowledge of Redpower 2 to complete this setup, http://integratedredstone.wikispaces.com is the official Redpower wiki and may be of great use.
Feel free to share this setup anywhere and in any form as long as you mention my username. If you don't, I will find out and prove that I was the original source. Or maybe I won't. Either way, you should still give credit.
Thanks for reading - I know it was rather long but I hope it proves helpful!
