It's like the old fast food warming lamps... but on the street.

 

I would like to see this adopted to help the homeless.

to turn on the heater. I cut my electric heat pump bill in half using local ir heaters and turning down the house from 72 to 68 degrees.

I thought about a more comprehensive ceiling based system, but the angles don't really work out well. The cost is high too. I just have a very small ir heater I move around to wherever I am sitting.

I used a few infrared heaters many years ago and worked great for heating me in the unfinished basement of my house. What the big downside was, the fixtures and other objects(chairs, desk, tools etc.) were still stone cold. The floor was no different, you didn't walk around in summer shoes down there. After completing the finished basement and extending the forced air HVAC to the area, bliss.

Infrared radiation emissions is a must must.

Cool concept that could have some really unique applications.  However, I'm not sure I want all that infrared radiation emitted to me throughout the day.

Alternative Solution

There already exists another solution to this problem, and I'm pretty sure that whatever IP rights were attached have expired by now.  It's called CLOTHING, more specifically layered clothing.  Of course it doesn't by itself solve the cognate problem of cooling, but it does have quie a wide range of "control" of comfort. Regarding that 20% of energy used by office buildings, at least 1/3 of that could be saved by PROPER configuration and control using in many cases the existing systems.   I work in a "class A" high-rise in Atlanta, and during the summer (like NOW) my desk area is unbearably COLD(in the mid to upper 60's F) because the existing VAV system has never been maintained and calibrated properly as interior configurations have been changed (relocation of walls, creation of large open areas where once stood enclosed offices, etc.) over the ~20 years the building has been in use.  Many of us have coats, jackets, or sweaters on our chair backs used ONLY during the summer!

The concept of heating the occupants instead of the whole room is hardly new. Back in the 1950s it was promoted as a very great idea in much the same way, except that the heat came from steam radiators or hot water radiators, and typically the concept was that the hot floor would radiate heat and all would be warm. The idea sort of worked in some places, and didn't deliver the claimed benefits in others. All that in an era when fuel for heating was quite cheap. My experiences with it left ne feeling a bit chilled, as I dimly recall.

I am not certain exactly what didn't work out, but my point here is that it is an old concept being revisited, not a totally new idea. The history of what didn't work needs to be examined carefully.

I wonder also if there might be a fire danger. Perhaps not, if the amount of heat isn't so high, but perhaps yes.

I think safety is the core issue in it.
