I read the article and I can't wait to read the published paper. This is an experiment that confirms Maxwell's Demon and the Demon is information.
As the particle moved up the staircase, it gained energy because it moved to a location of higher potential – akin to climbing a mountain. Yet the researchers never had to push the particle up the mountain (i.e. do work or input energy) – they simply used the information about which direction it happened to be moving in at any given time to guide the climb.
Energy boost
Not only were the researchers able to move the particle up the stairs, but they were able to precisely measure how much energy was converted from information.
The researchers describe their results in the Nov. 14 online edition of the journal Nature Physics.
In an accompanying essay in the same issue of the journal, physicist Christian Van den Broeck of the University of Hasselt in Belgium, who was not involved in the new study, called it "a direct verification of information-to-energy conversion."
The rotor is formed from two linked polystyrene beads each 0.3 micrometres across. One is pinned to a glass surface leaving the other free to rotate around it and the whole thing is immersed in fluid. Buffeted by molecules of the fluid, the rotor turns clockwise as often as it does anti-clockwise.
But then the researchers add a complex electric field that applies a gentle torque to the rotor, which varies at different angles. The torque is analogous to the force of gravity acting on the tiny ball on a staircase.
Like the ball occasionally moving up a step, the rotor is sometimes buffeted enough by other molecules to move against the gentle torque. Overall, however, it is now much more likely to move in the direction of the torque (equivalent to hopping down a step in the spiral staircase) than to move against it (equivalent to hopping up).
Finally, enter the demon, whose eye is a camera and brain a computer that controls the electric field. Whenever the rotor makes some progress in turning against the torque, the demon shifts the electric field so that the rotor suddenly finds itself nudged onto the top of that "step". This keeps happening, and the overall effect is to gradually climb the staircase.
As it does, the rotor gains energy. Crucially, though, the demon need pump no energy into the rotor, only information about the position of the rotor, which it uses to switch the field.
Video information about the rotor's position can be quantified in terms of digital bits. The researchers worked out that the exchange rate between energy and information matches theoretical predictions: at room temperature, one bit of information converts to about 3 x 10-21 joules.
Other researchers have summoned versions of Maxwell's demon before this, but they have not measured the energy gain and the information used, says Shoichi Toyabe of Chuo University in Tokyo, a member of the team. "We have verified that information can indeed be converted to potential energy and that the fundamental principle of the demon holds true," he told New Scientist.
Masaki Sano, a physicist at the University of Tokyo, and his colleagues have demonstrated that a bead can be coaxed up a 'spiral staircase' without any energy being directly transferred to the bead to push it upwards. Instead, it is persuaded along its route by a series of judiciously timed decisions to change the height of the 'steps' around it, based on information about the bead's position. In this sense, "information is being converted to energy", says Sano

The scientists used a high-speed camera to photograph the molecule. When it happened to be moving up the staircase, they let it move freely, but when it happened to be moving down the staircase, the researchers blocked its motion by inserting a virtual wall using an electric field.

While the amount of energy the system produces may seem insignificant, it might be enough to power nanomachines of the future, says Toyabe.

While the experiment itself does show that it's possible to create energy out of information, in practice, the technique doesn't offer potential for solving the energy crisis any time soon.

Initially, it seemed as if Maxwell's demon was getting something for nothing, creating a perpetual motion machine, but later it became clear that the demon must expend some energy in getting information about these random motions, so it wouldn't break the laws of thermodynamics after all. But nobody was able to physically demonstrate the demon and find out for sure.

"The true energetic cost of this information-to-energy conversion experiment lies somewhat hidden in its huge peripheral apparatus (including the doctoral student who is operating the experiment)," Van den Broeck wrote. "As such, the experiment is reminiscent of producing a tiny shot of energy from nuclear fusion in a reactor that is consuming considerably more energy."
What I'm trying to get at is this - you need to interpret the terminology in the proper context. For example, in physics the term "moment of force" does not refer to a timespan in which force is applied. If we were to interpret "information-to-energy conversion" in an inproper context (e.g. without looking up what it means), we might end up reading the article very differently from how it was intended. Certainly, we can agree on that?
When talking about information-to-energy conversion in this context, information is not being converted to energy, but instead used to create energy.
