Choose an Offering
Choose a pump by its offering: furnace fuel, nearby light, falls, struck projectiles, or powered redstone wire. Alternating forms vary the transfer rate over time. See the first circuit for a working route.

Burning
Dropped furnace fuel supplies stored run time; containers are consumed too. The pump draws colored Aura from its level and moves it to the first reachable network block above.
At one-block rise, Glowstone gives 180 eligible seconds at 750 Aura per second; Torch, 30 at 750. Falls add 2 seconds per block at 500. Furnace fuel grants its burn time divided by five at 300.

Projectile and Wire
An Arrow gives 20 seconds at 1,000 Aura per second; an Egg, 90 at 500; a Snowball, 10 at 500. Powered wire starts at 10 seconds and 1,500; each following wire adds 40% duration, up to 15.

Alternating Rhythm
Alternating offers triple accepted nominal speed, then a sine-like wave varies transfer from none to full. One rise-and-fall cycle lasts 20,000 world ticks: 16 minutes 40 seconds at 20 ticks per second.
