The Blood Dynamo is an energy producer from the Technomancy mod. The dynamo produces energy by taking in liquid Life Essence through any fluid pipes that work with Forge Liquids (ie. Liquiducts and Waterproof Pipes). The dynamo will output a constant 80RF/t when suppplied with Life Essence.
By placing the dynamo on or next to any an acceptable RF consumer or transfering device such as a Redstone Energy Conduit or Energy Cell, the dynamo will automatically face the device. As long as the dynamo is supplied with liquid Life Essence and a redstone signal, it will produce Redstone Flux (RF) at a rate of 80RF/t.
