Oh good. And about the jetpack fuel production, remember that it's also how you get oxygen for the scuba tank. (for people that don't just use morph or have a helmet w/ waterbreathing)There's an obscure config setting for the amount of energy needed to produce Hydrogen. You can drastically lower that. I believe the increase in energy cost is for a not yet implemented feature. So, bit bad on the timing. I need to test that out myself, so that generating fuel for jetpacks is still a viable option, but not as easy as it was before.
All other machines and energy producers have config options for their energy usage/generation. I personally set the wind turbine to half that of a standard solar panel, hit the heat gens with a massive reduction, and doubled the power usage of all machines, and I think x4 the power usage of the digital miner.
You can also use Minetweaker to remove or adjust the recipes to your personal sense of balance.
