I have been focused on HVAC / air purification recently.
Its amazing to me that these designs are less than two years old when the tech has been available for decades.
One of the biggest problems with the C-R and comparetto is that they are large and hideous to look at.
I have been working on a design that makes the C-R or comparetto or a smaller version than the 20" something that can be attractive enough to hang in the corner of a room as both an air purifier and room lighting.

- sammalloy 4y agoIt’s true. I don’t think popular, consumer grade luggage for the middle class had wheels until the 1970s. And if you watch for these kind of details in popular culture, I don’t think you even see wheeled baggage in the movies until the early 1980s. I couldn’t tell you the reason, but I think this was one of those status, income and class things: "I can afford to have someone carry my bags around."
