Elderly people with Alzheimer’s Disease or dementia sometimes forget to use the manual brakes on their wheelchairs, which then fall out from under them when they try to stand or sit. When this was brought to the attention of crop farmer Jerry Ford, he decided to do something about it. His invention is a rather clever automatic brake system for manual wheelchairs. It’s even designed in a way that still allows the wheelchair to fold up for transport.

This portrait is just one from a series of videos and photographs about inventors by photographer David Friedman.

Now this is an environmentally-friendly and resourceful improvement on a scarecrow! It seems that, without the use of harmful chemicals, this Japanese farmer came up with a simple system to keep local crows from eating the vegetable patch.How? Things are kept moving and shaking around the growing plants using that roaring little river next to the farm. Follow the strings!
