Garden Design Ideas

I have to think of a product from the following lists which is in need of a redesign these are:
LIST A
Indoor fitness or exercise products( for example a treadmill)
Garden tools or machines(for example a lawnmower)
Soap dispensers(domestic or public)
powered aid for the elderly or disabled(for example a stairlift)
supermarket trolleys
LIST B
Personal Hygiene or grooming(washing,hair cutting,shaving or nail care)
DIY or home maintenance
Computer based digital products
audio visual consumer products
practical goods for babies or children(not toys)
Can anyone come up with any ideas for something on these lists that need redesigning or you have come up against something on these lists that aint working for you and think it could be made better????
many thanks

I would love to have a wind turbine in my garden, to generate electricity but I am sure most of you will do to, and the reason you don’t have it (and would agree with me) - everything they sell nowadays is big and ugly, especially if your garden is small and you are not allowed to install anything big on your roof.
I wonder why they don’t make wind turbines in the shape of anemometer - they would not take too much place, and would look good anywhere.
Or make a sleek wind turbine based on the design of those advertising banners they put outside of the stores- they spin like crazy in the wind.
Do you know any reasons why they don’t exist?
Pobept K - I love big industrial ones, they look so beautiful, especially when there are many of them, but if you have a small garden - every small wind turbine is still big for it, and look rediculous there, taking half of it.
