Reuters is reporting that defense contractor Lockheed Martin claims it has made a technological breakthrough that places us on the doorstep of affordable fusion energy. Supposedly, the breakthrough will result in compact fusion reactors before a decade is out.
But the Lockheed Martin press release that coincides with the coverage says little of the sort. There, the company simply states that after initial work in the area, it expects to be able to build a prototype in five years. If everything goes well, the design could "be developed and deployed in as little as ten years." The "if" in the last sentence, however, is a big one.
The hype also seems to have been designed to leverage a technical article in Aviation Week that goes into some of the details about how Lockheed Martin is structuring its design. The general concept is similar to a Tokamak, in that it involves magnetic confinement of a plasma rather than hitting a small target with massive amounts of laser power. But the shape of the container is different and, according to the company's researchers, more efficient. However, the Aviation Week report also notes, "The team acknowledges that the project is in its earliest stages, and many key challenges remain before a viable prototype can be built."

Cosmic clouds form fantastic shapes in the central regions of emission nebula IC 1805. The clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15. About 1.5 million years young, the cluster stars are toward the right in this colorful skyscape, along with dark dust clouds in silhouette against glowing atomic gas. A composite of narrowband and broadband telescopic images, the view spans about 30 light-years and includes emission from ionized hydrogen, sulfur, and oxygen atoms mapped to green, red, and blue hues in the popular Hubble Palette. Wider field images reveal that IC 1805's simpler, overall outline suggests its popular name - The Heart Nebula. IC 1805 is located about 7,500 light years away toward the boastful constellation Cassiopeia.
