Best way to get infinite lava

ATM 10

I am relying on mekanism wind generator and powah magmarator and furnator but I don't have a constant supply of it.

I am currently using the function drawers with 3 lava dripstone upgrades but when I need to craft powah crystals, i get energy shortage so I manually bring some lava from nether in mekanism tanks.

So I want to know what's the best way to get infinite lava or atleast pretty good supply of it. I have decent amount of resources to craft costly items.
