Combustion Engines, infinite energy!

Ok, here we are. First of, this uses the Equivalent Exchange mod to turn cobblestone into lava (some intermediate steps are required XD). Second, it uses Redpower 2's Deployer to put that lava in a place where a Buildcraft 2's pump can gather it, put it into a deposit, and use it as fuel for combustion engines.

Notice the following points:

1. Lava is not as efficient as oil or refined oil (fuel), so don't complain because the pneumatic energy produced is not as good as you want.
2. Lava heats more the combustion engines, thus more water is required.
3. I advice against making the engine rows more than 8 engines in length. Usually, six is more than enough.
4. You can power several lava pumps if you want, and with that lots of engines. I'm presenting only a small setup, a prototype if you prefer.
5. This uses Equivalent Exchange version 4.x, the previous one to the current. I'm working in a new version, but I think it won't use the cobble generator as source.

Now with the explanations. The conversion chain up to the lava buckets you all know from the video: cobble from the cobble generators gets turned into redstone blocks, that in turn are transformed into redstone (dust), after which 3 redstone are turned into 2 coal and 2 redstone remain unchanged. Then the last step is to create a lava-filled bucket.
Redpower 2's deployer then puts the lava in a predefined place where a BC2's pump can take it. Meanwhile, the advanced wooden pipe takes away the empty buckets for reutilization.

Since lava can be used as fuel by the combustion engines, we can now power as many engines as we want, for as long as we want, andif we make the rows of six or seven engines in depth (for a total of 12 or 14 engines) it won't explode as long as we have an active water pump.

I hope you enjoyed the video!
