I wish we had three phase everywhere, including our homes. If one wants to run anything like a lathe or mill of any size, we have to use converters, or starters (static converters). When I had my shop, I contacted AEP about installing three phase, and the cost of the transformer bank alone was enough for me. I installed a rotary converter, which I home-brewed, made from a surplus 25 Hp, 3 Ph. motor, and a 120 volt, 1 ph. pony motor to start it rolling. The so-called static converters are nothing but a starter using capacitors, and when they drop out, you lose 1/3 of the power you should have from the motor. The other route, you pick up the third phase from the converter motors winding.
