I love the robotic lawn mower our neighbor has. They have a couple acres and half is flat, so I occasionally see this yellow thing about the size of a gas mower without the handle silently going to it's boundary, turing 90, turning 90 again and mowing back.
Moving sidewalks are in most of the larger airports. Lots of fun unless you're hoofing it on the sidwalk and come abruptly to the non-moving floor without paying attention to the warnings!
Yes, we do have internet, cell phones with 2-way radio, pix & email capable, video phones. Solar powered parking meters. Actually, lots of smaller solar powered things, like lighted road signs, landscape lighting, etc.
Unfortunately, US automakers have sent us in R for reverse with the steroidal trucks and SUV's that get well under 20mpg. And what's that Hummer all about, anyway? At least Japan is moving forward with the Hybrids. Hopefully, fuel cells are coming soon.
Not quite what we were told to EXPECT when we were in school in the 60-s and 70-s, eh?
PS, I like to cook. Forget cleaning, I'm a slob, when I can get away with it. Could use that robotic vacuum.... not likely to get it, though.
