I love technology & I'm all about new ideas. But, to this day, I'm struggling with the mag bearing concept.
Power failures are a fact of life. A well oiled machine can handle the occasional coast down without an oil pump. I even have some older machines that have a coast down reservoir for times the oil pump is off due to a power failure.
Also, the electronics on some of these sophisticated machines can break the bank when the repairs come due.
I know I'm partial on this, but, I just don't see how you can beat a simple machine, with a simple control package & a simple oil circuit.
