Well... some of those are cool and believeable... but some of those aren't believable...
Rice cleaner??? COME ON!!
And the parking one... guess that wouldn't work well on a big 4x4 truck.
Then some of those are pretty common.
I really like the recycle one though!! might help with litering!!
Rice Cleaner? Hell yes! You know where they grow rice don't you? The recycling bit we have here too. You take your empty case of bottles, put it on the conveyor belt, and you'll get between 2-5 bucks back for each case depending on what it is i.e. Coke, Juice, Beer etc, etc...I love it. It does help with the littering since a case will cost $15 or so, and with the deposit you get a new one for $12. The rest however...Water Salad? Used Panties? Japanese are "different"
