Introduce designer washing powders or liquids scented with perfumes such as Obsession or Chanel No.5.

Design a computer with two mice, one for each hand. The non-dominant hand would help with processing tasks rather than typically laying idle.

Introduce a system of 'survival' tokens in varying denominations which the public can purchase from high street stores, then give instead of cash to the homeless. The tokens would be exchangable for food, clothing and non-alcoholic drinks.

Open an eat-as-much-as-you-like buffet restaurant that weighs you when you enter and again when you leave. The restaurant will charge diners according to the amount of weight they have put on, in a similar fashion to pick-your-own fruit farms. It would be called Heavy.

Introduce 'talking' or 'quiet' seats on airplanes, which would be offered in addition to the routine window or aisle options. Then, they can seat passengers according to their chatting preference. Extroverts will be assured that the person next to them wants to make small talk as well, and introverts can be guaranteed a quiet ride.

Introduce bench meters to public parks. These secure coin operated devices would work like parking meters. The new income stream generated would pay for the maintenance and cleaning of existing benches and the purchase of additional benches. Off-peak times (i.e. dusk to dawn) would ensure that homeless individuals electing to sleep on these benches at night could do so without the risk of incurring a financial penalty.

Have you ever needed the restroom so badly? You run from store to store and they all tell you that it's out of order? Well I've been thinking that they should open a chain of restrooms similar to McDonalds where you can buy a yearly membership card and have access to hundreds of these rest areas spread out throughout the country. You would have access to showers, toilets, baby changing area, nursing area, vending machines that sell toiletries etc. It's about time something is done to...

Introduce parking meters either on public roads or in car parks that can be accessed remotely by telephone. Each space would have its own pin number allowing the owner of vehicle the opportunity to top up their allocated time by credit card payment without returning to the vehicle.

Introduce digital cameras with built in gags or funny sounds. The gag button could be pressed before the picture is taken as a novel alternative to everyone saying 'cheese'. Camera owners could download refresher gags and noises free from the web.

Design pants with towelling pocket linings for businessmen of nervous dispositions and sweaty palms.
