1. Residential kitchen spaces/ cabinetry that mirror an industrial or commercial kitchenThis topic makes me think accessibility and efficiency. Knives on magnetic strips, pots hanging overhead, spices out on shelves above the stove... everything in reach so you can work quickly and get the job done. Also, how others have mentioned, the industrial cooktop with grill/griddle. My current house (rental) has a nice range with the oven split into two. Not sure if this is "industrial", but it is damn efficient and allows multitasking (we have 5 adults living in the house, so it is super convenient).
2. Residential kitchen spaces/ cabinetry that is inspired by the modular and small space solutions in AsiaYou could also look to the "Tiny House" movement for example homes posted
here. Many of these homes have under-counter refrigerators, single or double burners that can be plugged in on the counter or stored away, butcher blocks that fit perfectly over the sink to add more prep space, etc... I also love the concept (Finnish? perhaps) where the dish dryer rack is stored in a cabinet above the sink. saves counter space, and if you put doors on the cabinet the dishes can just stay there once they are dried! I am currently building a tiny house, and I LOVE cooking, so saving space and finding creative solutions is a really interesting topic to me.
3. Residential kitchen spaces/cabinetry that helps homeowners feel they are less wastefulA few things come to mind. Saving space, which relates to my notes on #2, reducing waste generated in the kitchen, and proper disposal of the waste. For the second point, I probably have biased exposure on this, but I see a movement towards purchasing in bulk to reduce packaging. With this comes increased storage in reusable containers such as mason jars, which are both functional and aesthetically pleasing. Suddenly your pantry items can be on a shelf on display, and easier in reach. Also, a big source of waste for us is the fridge. Again, we have 5 adults in the house, so keeping track of produce and not letting things go bad is a challenge. Shallower fridges, perhaps, though possibly less energy efficient, would go a long way (for us) in reducing waste. Lastly, as someone else mentioned, integrated waste disposal solutions for trash, compost, and recyclables. We are really bad about composting because our trash and recycle bins already take up a lot of room on our floor, and we do not have extra counter space for a countertop bin...
4. Residential kitchen spaces/ cabinetry that incorporates sensor technology to monitor cabinet contents and activityEhhhh, I've seen these concepts, particularly in hand with future auto-subscription services through amazon etc. I also work in energy research and the "Internet of things" is a big topic for my work in electronics manufacturing and data center energy consumption. So yes, we are able to cheaply slap a sensor on everything, and with the right software/apps can make some really functional services, but... I just personally am not feeling it. I think it is highlyyyy unnecessary in the grand scheme of things and could really see it making things more complicated than more simplified.
5. Residential kitchen spaces/ cabinetry that reflect home-owners that eat out far more than they eat in (how would a kitchen change? what would the space prioritize?)I think this relates to #2 (small kitchens) and #3 (managing waste). I think you would still want all the basics, but certainly less prep space would be required, as well as less space for gadgets (blenders, mixers, etc). Except coffee, everyone loves coffee and wants a nice little coffee station :)
