Product #4 : The F-RayA directional, high-energy (1kW) radio frequency emitter

The original idea this replaced was WERC, my hypothesis of WASTE ENERGY RE-CAPTURE.  This is going to be the most important industry on earth by 2050 and I plan to lead the way in bringing this technology to residential dwellings all over the world.  Note we did not intentionally abandon the idea, but rather decided we couldn’t do an adequate job proving our ideas in the time we had.

My WERC designs included one I had already prototyped with incredible success: the AC condensation collector.  My condensation collector is a 5-gallon water jug attached to the downspout from my rafter-mounted AC evaporator.  During the hottest months of the year, it captures 2.5 gallons of condensate per day.  This summer, it was enough water to take a crop of green beans, of peas, of onions and of tomatoes to the tune of about 20 plants.  The fruit was excellent and full of nutrition, and none of my family went crazy or died.  So, I plan on developing it further to capture truly food-safe water.

WERC designs we discussed included moving the hot water reservoir to directly atop the AC condenser.  On hot days, this means using less gas to get the same amount of hot water would be an intentional consequence of running the AC unit.  We decided that on cold days the same system could loop through the cooling tubes of your refrigerator.

Privately, I have at least a dozen amazing WERC designs.  Anyone want to work with me on bringing them to life?

Other designs included the “smart stove,” which has no plumbing coming up to the user’s knobs but instead uses Arduino to control valves deep within the machine.  The smart stove recaptured waste energy by expelling its hot air through a Seebeck generator.  It also used two sensors on the cooktop to determine if fire was on and to determine if a pot was on the fire.  It would automatically light the burner you dialed in, but if you forgot to get a pot onto the stove, or if you left the fire on and forgot about it, it would automatically shut the fire off.  And it could be programmed with recipes like, “bring to boil, simmer 15 minutes, then keep warm 45 minutes.”  And of course, its companion app would know your location and commute time, so it could start your cooking when you start your commute home.  This automates some of the processes you used to take a lot of time on only AFTER you got home from work.

We have many, many WERC devices in our minds and we want to bring them all to the society at large.


Now to talk about the F-Ray.

I designed it as a microwave emitter in a self-contained package.  I had to use primitive means to bend the sheet metal, including hammering and hammering boards onto it.  Creating a Faraday cage was tricky and required careful planning each step of the way.  By the end of the project, though, we had a very safe emitter that produces a spotlight of microwave energy which we confirmed by boiling a plastic water bottle until it melted and exploded and by burning the heck out of a CD.

Objects deconstructed included two microwave ovens, tabletop timer, a steel-screen barrier, a computer and the computer’s power supply.

It’s a one-kilowatt microwave spotlight, essentially.  And it’s really heavy.
