INTRO: DARPA, the US Defense Advanced Research Projects Agency, is now working on developing a magnet-driven silent water propulsion system – the magnetohydrodynamic (MHD) drive. The primary reason is to develop silent military naval craft. Imagine a nuclear submarine with an MHD drive, without moving parts, that can slice through the water silently. No moving parts also means much less maintenance (a bonus I can attest to, owning a fully electric vehicle).
But don’t be distracted by the obvious military application – if DARPA research leads to a successful MHD drive there are implications beyond the military, and there are a lot of interesting elements to this story. Let’s start, however, with the technology itself. How does the MHD work?
The drive was first imagined in the 1960s. That’s generic technology lesson #1 – technology often has deeper roots than you imagine, because development often takes a lot longer than initial hype would suggest... (MORE - details)
