Brava Comes Out of Stealth, Introduces Oven That Cooks With Light
By Michael Wolf -  July 10, 2018 1
Called the Brava, the eponymously named oven can reach temperatures of 500 degrees within seconds and is supposed to use less energy during a cook session than a typical oven uses during preheating, all by cooking with high-intensity light technology that had previously been used in industrial applications like heating metal and semiconductors.
The Brava oven, the company says, is “the future of cooking.”

But I’m getting ahead of myself. Let’s go back to the beginning of the story.

Cooking with light, sounds like perfect evidence of the charge field to me. Maybe Miles will get some additional recognition.

Interesting... came across this which also looks C.F. related with Miles':

new oven that bakes with light GIMOD

The research that led to this commercially interesting application started from the quest to detect the position of suspended graphene membranes with a laser beam. Subsequently, the researchers realized that they could turn the optical readout mechanism on its head and use the array of graphene “drums” as a GIMOD.

The GIMODs are produced from two layers of graphene that are assembled using Graphenea’s patented semi-dry transfer method. The double-layer graphene (DLG) is then transferred to a substrate that houses the array of holes that forms the basis of GIMOD. This results in an optical cavity with a movable

absorbing membrane made out of DLG and a fixed mirror formed by the underlying silicon surface. The silicon substrate also plays the role of back electrode for electrostatic actuation – controlled deflection of the membrane. The spacing between the membrane and the back electrode gives the color that is reflected back to the observer. Since each pixel is contacted independently, GIMOD can produce a color matrix with resolution that is well above what the eye can discern. The high yield of the graphene growth and transfer processes are key certificates to potential use in real-world, batch-produced products. The first GIMOD prototype attracted attention of the display industry when it was shown at the Mobile World Congress in 2017.

Other than low power consumption and high performance in bright environments, the reflective-type (e-paper) pixel technology has the favorable property that it reduces motion sickness in virtual/augmented reality applications. The paper describing the GIMOD was published in Nature Communications.
