One possible explanation is the "Polywell" project. A few years ago it got announced that the researchers were now being funded by the Navy, and then they went quiet. The Polywell idea is a compact fusion reactor that uses magnetic fields more than raw heat, in a device resembling a wiffle-ball. It's one of several projects trying to circumvent the extremely slow and expensive R&D projects being done by the US (NIF) and Euro (ITER) governments. A Canadian company is working on a similar reactor with a steampunk theme.
(For anybody here that doesn't already know this: technically manmade fusion reactors have existed since the mid-20th century, invented by Philo T. Farnsworth of the CRT television. They just don't put out more usable energy than they take in, yet.)
Wonder how many of this group are responding to polls?
