"Love the concept and design, from the actual form factor to how they make the filter.  But as eco friendly as this may be, do we really need another bottle?It's the same problem with grocery bags, we have every intention of re-using cloth bags, but more often than not, we end up buying more cloth bags with the "intention" of re-using  those bags or end up buying extra paper or plastic bags , "just this once."What we really need is behavior modification, and I'm sure that as the tracking and predictive algorithms of our wearable devices become more robust, we can get that gentle buzz on the arm from our smart watch, reminding me to bring my damn cloth bags, which will know I'm headed to the store after it has tracked me getting up from my couch at 9:00 PM toward the fridge, and then toward the front door."

"One of the few critical Core77 articles that have technical merit.   On the design of bike head lights, the handle bar, stem or forks are actually not the best places to mount a light; it needs to be separate from bar movements, which is why they are typically supported by the frame on motorcycles.  We need a non-integrated way to universally mount lights to bike frames and still offer the same efficacy and adjustability of a bar mounted light."

"Speaking as a cyclist, motorcyclist, and automobile driver, E-Bikes at least address the immediate present problem at face value, which is the speed differential between vehicles on the road.  But as the comments show, the problem is multi-faceted.Even when you take the speed differential out of the equation, you have the issue of visibility. Drivers, at least in the USA, are not used to seeing 2 wheeled vehicles with any sort of frequency that even motorcycle riders don't register even if they are in a driver's visual field.  People just won't see you unless they are conditioned specifically to look for you."

"Very well said.  The problem is multi-faceted and it seems you have addressed this well."
