Batteries not included

Doing some online shopping for household goods - potentially the most exciting part of my move. I am shocked at how many things there are for lazy people. a) How can you justify saving this much energy and b) who has space for all this stuff?
The most egregious examples:

• touchless self-opening trash can (this is one in a series of "touchless" appliances including a can opener)
  
• battery operated flour sifter
• cornbread pan (circular with walls to create triangles - to avoid cutting pieces post-bake)
• electric knife (I consider this a liability)
• "one touch" jar opener - this thing is a standing counter-top piece of machinery almost larger than a coffee maker
• electric salt and pepper grinder
