"I like that it would be so thin that you could mount it on the wall and it would essentially look as though it was mounted 'in' the wall. This along with falling prices will lead to more of a situation where tv are not just for consuming tv programmes, but used as a picture frame of ones photos or perhaps used as a 'window' particularly for small apartments with little window access or stuck in the middle of a city to see into a forest or open field."

"As much as I like the idea of plastic reduction or elimination, this 'rethinking the toothbrush' is very one dimensional. Besides a 'sample' of one person is statistically insignificant when considering 'people' I'm doubtful your hand is in the 99th percentile of sizes, there may well be other factors such as use by disabled, packaging machines that would have to be retooled and other unforeseen knock on effects. Besides there are more novel solutions such as using your finger as the handle and putting a finger glove on with bristles. There are techniques to fill the centre of plastics with inert gas, thus reducing the volume of plastic, but at the same time providing a more pleasing shape to use. Perhaps choosing a different material all together such as wood with horsehair bristles, if only because ingesting plastic is a big concern to me and wood degrades more quickly and isn't as toxic to the environment. All of these involve redoing product, perhaps increased material cost both in monetary and perhaps deforestation in the case of wood handles. The real solution is to make it too expensive for these companies and consumers to not consider these factors of environmental consequences and whole life-cycle of a product from sourcing and manufacturing, packaging, transport and eventual repair, replacement and finally reuse, recycling and waste management. Sure it does make it a huge task, I was made aware of this when studying product design and it is far from trivial. Even simple things such as some schemes in I believe Scotland where you return your beer bottles and get a significant amount of money back encourages this mindful behavior, the bottles presumably are cleaned and reused, reducing not only virgin material usage, but also the amount of energy used to make that initial bottle. General waste bins in Germany are weighed and users charged accordingly to encourage recycling via the 5-7 bins for the different materials.I like the thought experiment and that a tiny change can have such a large effect in a global sense.  Just pointing out that if you are going to have a title 'rethinking the toothbrush' I would expect more then just cutting the end off."
