I think the Heated Redstone Generator should have a quest added in for it, maybe after the Reactant Dynamo Quest. If you use Destabilized Redstone, you can get 320 RF/t out of it. 100mb of the stuff lasts for 250 seconds and produces 1.6M RF. With all of the dust around, and the number of pulverizers you can run off of 320 RF/t (8), it's a very good and very stable power source, since you can sieve the dust for redstone. The quest would require making the generator and making a bucket of Destabilized Redstone. Bucket would not be taken upon turning it in, or if it is taken, it would return an empty one. Rewards could be a choice of redstone (maybe half a stack?) or a Greater Reward Bag.
