“Anybody who is skilled in the art and understands what he’s proposing is going to have this dumbfounding reaction: ‘Oh, well it’s obvious it’ll work,’” said Darnell, a biochemist with an extensive background in thermodynamics. ...

A major stumbling block for solar thermal energy devices invented to date has been that, as temperatures rise, increasing amounts of energy escapes, or radiates away, from their receivers. At 1,650 degrees Fahrenheit, currently designed receivers would radiate as much energy as they collect, sinking their efficiency to zero, solar experts say.

In his patent application, Ace wrote that his invention amounts to “a high-temperature blackbody absorber”. ...

The key, he said, is his trap’s ability to absorb nearly 100 percent of the sunshine that hits it, while allowing only a tiny percentage of energy to escape, even at ultra-high temperatures.

Such a feat would astound many solar experts, who have had little success combating radiation losses in pilot solar plants, which use fields of mirrors to redirect and concentrate sunlight on common receivers.
