is there any thing else known of this like a youtube or something

any idea of the cost?

It seems like a good idea, but also if you do have this kind of carpet, wouldn't it be creepy yet irritating at the same time? Your eyes are more sensitive at night, so the light off the carpet could be pretty annoying

I don't really think this is a good idea, because carpets catch a lot of things (i.e dirt, bugs, food) and sometimes the vacuum doesn't pick all of it up. They should design one which accommodates wood or just introduce a cleanlier type of carpet.

I am just curious to how this would hold up if a dog soiled on the rug or certain liquids spilled on the rug. Also what different temperatures could do to the phosphor it being really cold/hot in your home. Typical battery usage and how often you would have to recharge. Lastly what type of weight limit the rug could handle and how long it stays illuminated after each step.

As with most applications that are designed to solve AN issue, they wont apply to all. If you have an energetic dog that soils your rugs now, then don't get a light up one! Simple as that. I see this doing quite well in homes with small children, or a great gift idea for for your grandparents. As stated in the article the glow is similar to a watch or current night light glow; if you have seen those, then you should know that it's not a blinding light, it's very subtle, yet very helpful. I think most questions in these posts are answered in the article (yes except price.) I suggest people look at the concept and idea of the rug not as a "one fits all" mentality. There are other answers for those pet owners out there. Maybe wallpaper with the same tech, only instead uses motion sensors to light your path just in front of you....
