"It doesn't specify that it has MIPS. If it doesn't, then it is less safe than existing bike helmets, which negates the supposed added security of being tight fitting. I don't see a reason why it wouldn't have MIPS, and I most definitely don't see a reason why anyone would buy a helmet that doesn't have it. (MISP let the helmet slide over your skull, so that if you fall on the asphalt while moving forward, the helmet doesn't jerk your head sideways. The helmet moves, but your head doesn't. This is to prevent concussion and neck injury.)"

"Cast iron pots were the technological advancement to hand beaten, tinned, copper pots, or riveted plate iron pots. The technological advancement from cast iron, were cast aluminium, which is lighter, and have superior heat conduction (meaning no hot spot at the bottom.) the downside, was that aluminium is toxic. The stainless steel pot with a sandwich bottom, which means that there is a copper disc between two sheets of stainless steel, which is there because of coppers high thermal conductivity, which makes the temperature even, and reduces the risk of burning the food, is the latest technological advancement. Now some of them include an iron layer below the copper, to work on induction stoves. All this article is saying, is that a 50 year old technology, is better than a 250 year old technology. (Don't really know the numbers, it's just a rough guess.) Because the technology is 50 years old there are plenty of high quality seconds hand pots available for next to nothing. Meaning when it comes to expense, you can have the best for the cheapest. Cast iron pots are like vinyl music. It's value is in it's materiality, not it's on-paper performance. Meaning that people who like cast iron, will not buy a stainless steel sandwich design, for the simple reasons, that this is what they owned, before they bought their cast iron. To me, this pot looks exactly like a pot with a lid, that I can buy for £2 at the nearest charity shop, so I don't really see it's "unique selling point.""

"Glass requires a lot of energy to be molten and shaped. The carbon footprint might be less with this design, even if the whole thing is burnt for energy harvesting. Also taking into account the reduced emissions from transporting the lighter packaging.I personally think the aluminium can should be adopted for wine. In the US you already have 750ml aluminium cans. Aluminium, like glass is easy to recycle. The drawback is the embodied carbon footprint in the production of the aluminium, but the upside is that aluminium has a high value. Hydro has been talking about "urban mining" which sees the waste stream as ore, and although there isn't that much aluminium in it, it is pure aluminium without the need for the very expensive refining. In Norway, with a deposit scheme, about 97% of cans and bottles are returned for recycling."

"The biggest advantage, is that it makes it easy to use post-consumer  plastic. If it's about cost, then ground-up recycled plastic would be cheaper than virgin plastic. Recycling old prints is also much easier than recycling other post-consumer plastic, in that only a few types of plastic are used. Cost of printed parts could also be offset by supplying the plastic, in the form of broken or unwanted prints. "

"I don't really see what they have done that is so special, sheets made from recycled plastic have been around for decades. It is the identification, cleaning, and knowledge of the history ( plastic exposed to the sun for years will have degraded, and will not be as strong, low molecular weight does not change by melting it)Once you have plastic waste that is cleaned, of known quality, and all the same type of plastic, you have raw material, which in itself has monetary value. If anything, it would be more environmentally friendly to use this raw-material to replace Virgin materials. Plastic has a high carbon footprint compared to MDF, which is the material this product is competing against."

"What can this do, that a measure tape, or a Swedish style folding ruler can't do? This thing is not intuitive to use, maybe not able to measure internal dimensions, will eventually create electronic waste, got a screen that can be smashed if it falls on the floor, might have calibration issues, and by appearance has a string that can get tangled or break. I could see it being used in a workshop, but not on a building site. I also agree, that as a styling exercise for an industrial design course, the design has no relevance to the festiol aesthetic.But having said this, I think improving on existing tape measure and folding ruler, and laser measure, is virtually impossible."

"I don't know why he thinks those blades are expensive, they are about 50 cents if you buy bulk.Secondly, the expensive blades have Japanese sawteeth that are really sharp (cheap blades are dull) which this machine doesn't cut. I guess the teeth it cuts are not good for metal either, and they aren't set to make the cut wider than the blade. Secondly, the original teeth were probably hardened, and the new-cut teeth won't be.This machine would be perfect for a hardware store that sharpen the blades of the customers. You'd need to sharpen 400 blades to make up the cost. And the criticism is not really relevant, if it cuts, it cuts."

"Exactly, there is no need to make it this big, or this bright. It could be ring that goes around the stem, and around the seatpost. Literally just a silicone ring that is permanently mounted, with usb-c charge port. It wouldn't be in the way, and you wouldn't forget it, and it would add so much weight to the bike."

"There was an article on this site, about a machine that made bricks from rubble. This article effectively refutes the opening statement of this article. You can make new bricks from old bricks and mortar, and some people have already built a machine that can do that. From a energy usage point of view, 100% of the mass in a glass brick will have to be heated, while for a brick made from rubble, only the binding agent (i.e. cement) will have to be heated, so much less. The other aspect is how dependent this glass is on correct cooling. If a cooling kiln is needed, it is more like a factory, and these bloks are just a version of the Heineken brick-bottle. If however no post-printing cooling is needed, then one could take the machine to where the glass is, and in sunny climates one could probably use computer controlled mirrors to melt the glass, and make it the right temperature. If this could be achieved, then it could have some potential. Especially in countries that rely on local manufacture."

"I got one, and use it for work. The main downside, is that changing the blade is done by undoing a screw, which is easily lost, and awkward to do. It also has low build quality, and is made of stamped out sheets of stainless steel that are welded together. As a knife it works fine. It's not for applying a lot of force, but it's also something you can carry without it being in the way. And the clip is super strong, so it will stay put. All this being said, a 9mm olfa knife is much better at being a small knife, primarily because of easy access to a sharp edge. (By breaking off the dull one)"

"Silver is also anti- bacterial, so they can be white as well. I've never before considered the need to clean door handles, neither have I worried about being injured by them. Like you wisely pointed out, material choice can negate the need of cleaning. I'd say that the primary function of design, is to be beautiful. Sure functionality should not be sacrificed, but when it comes to door handles, there isn't really much that can go wrong. After all is said, this design is much more ergonomical, than the round one, which requires grip strength and dexterity disabled people doesn't have.."

"I would imagine a bigger insole will do that work?"
