To add to this rather than make a new thread; since I've looked into adding this to my AAI/BZ multiplayer game which is near achieving 10k science per minute.
The electric foundry consumes just 3kW more than the non-electric 90kW and thus easily powered by a couple solar panels; this is trivial when researched that late into the tech tree, even with modules. The industrial furnace by comparison uses 517kW with the same crafting speed and technology, yet is drastically impacted by the productivity/speed modules consumption penalty. This leap in consumption also applies to the electric furnace when compared to the steel furnace too.
I believe the electric foundry would make for a good addition to the mid-tier 'blue science' technology; with AAI compatibility allowing the industrial furnace to be capable of foundry recipes. This would balance the two mods much better, plus allow AAI players to use 5 modules instead of 3, which for steel plate is a major difference compared to the much lesser used silicon, cermet, etc. (Requiring twice the number of steel producing foundries is excessive late-game, with power being irrelevant at that point anyhow.)
Other than that, I like the addition of solid fuel for more heat intensive smelting. It's like Angel's Smelting, only more vanilla themed and simplified.
I look forward to seeing what new ideas and features will be added over time.
