"Why not have the case and batteries and have the ability to swap them out without a crazy expensive charging toaster. I'd love the ability to keep a spare battery in my glove box. Given that phones today don't allow swappable batteries that would be an awesome thing.  My son is always running out of battery. Swappable batteries are faster than a charging block and cable. Great idea, bad execution"

"I love the idea but imagine the expense comes from milling. It doesn't look like an easy milling profile (certainly not a simple rotary bit) To keep costs down, a custom spline could be used and a router bit could be provided to make any solid flooring work. I can imagine a few profiles that would work well. You'd have to redesign the clip but the concept is pretty nice. Having a floating floor I'd love the ability to access underneath or replace a board that got damaged without it being a fullday event. "

"This reminds me of Twiki from Buck Rogers. That robot wore a smart computer named Theo. This is sort of a reverse Cap Camera too. I am sure there would be a protocol to start the camera and mic if you were being pulled over. Once cloud storage becomes infinite these things will record everything though. That is just like a Black Mirror episode. I kind of like it and hate it at the same time. "

"As a concept to utilize an established recycling system, I think this is great. From the use of raw materials and transportation costs, this misses the mark. I like what Blueland is doing by selling nice glass and metal pump bottles and then selling concentrated soap tablets wrapped in paper. I love their product. It works great. It uses no single-use plastic and reduces shipping costs. I've only transitioned to their hand soap at the moment and will be doing so for other products. Why recycle anything if you can avoid using it all together? "

"Having used many lasers over the last 20 years, I love the concept but am very concerned. When rapid moving how does it account for the mass of the unit? I would think it would slide all over the place. Even in the track, I can't imagine it will be that accurate. God forbid it got bumped toward the end of a print. Also, what about all the smoke and potentially toxic gas just venting in the open? "

"Please make them in white with spots. You'll look like Toad from Mario Carts. Yaaawhoooo"

"The material is EPVC (expanded PVC). Often it is used as a wood replacement in trim on the exterior of homes. It is used in the sign industry a lot. Often it is referred to by a brand name like Sintra or Komatex"

"What happens to the motorcycle? Does that mean there are 6 motorcycles crashed at the bottom of a cliff that some intern had to go and clean up? This was all super impressive though. "

"They appear to be screwed together with plugs hiding the screws. Bonding HDPE with plywood is tough. 3M makes an adhesive but not much works and it is more expensive than screws. I like that their design utilizes most of the sheet of HDPE with little waste. I don't think I'd break them down much but it sure would help when moving. "

"For one we usually have waste aluminum that is small and hard to use. We used to make brass knuckle bottle openers out of 1/2" thick aluminum for fun and nest them into what would just get recycled. When you buy plate aluminum in 4x8 or larger sheets you try the best you can to use it all. If it is scrap then the cost is only what the recycler would give you which is 50 cents a pound. Much nicer than a plastic soap dish that can't get recycled."

"If the mailbox is within wifi range just put in a Blink camera in the back. You can then look inside to see if you have mail. I like the drone idea though. Way cool to have your mail fly to you and then back to dock on the post and charge."

"Saying it holds 10 grams of beans is really not accurate. Coffee can weigh differently based on how the beans were roasted. If you weighed 5 scoops each one would have a different weight. It is a really nice-looking object but really serves no greater purpose other than a spoon. The best way to get good coffee is to weigh your beans for a consistent brew. My scale doesn't care how the beans get on it. Seems to me that someone had the means to make something and didn't ask if they should. "
