A major problem when designing storages is the space needed for them. Mostly there is a little place left for a storage and turning it to well functioning storage, one needs creativity, to start with. Imagination, logic and new trends and technologies give the opportunity for a little hole, high ceiling, narrow space and similar to be designed as a storage space. The following pictures 11, 12, 13, 14 and 15 depict examples of different solutions for a storage spaces.

Based on the water preservation theme, ‘Future of Water,’ of the Whirlpool 2008 Contest, the Re-Cycle is a sustainable washing machine design that seems well equipped to tackle the water crisis looming large across the world. Designed to match modern residential apartments, the revolutionary washing machine comes with a three-in-one Laundry Center, including a washing machine, a dryer and filter with water tank. The water used for washing the clothes doesn’t go to waste, as an innovative mechanism deposits and recycles the used water in a separate tank that can be used for the next wash.

Picture 6 represents a system for grey water recycling which deals with the water saving problem.
About 40% of freshwater coming into the average home is used just to flush the toilet. When tucked inside the cabinet below the bathroom sink, the Aqus system cuts that number significantly. Instead of using freshwater to flush, it catches the water that goes down your sink drain, filtering and disinfecting it and then quietly pumping it to your toilet tank. (The recycled water is even safe for toilet-slurping pets.) When there’s not enough wastewater for a flush, Aqus pulls from your plumbing. The system saves up to 14 gallons a day in a two-person house. An alternative for Aqus, which is easier and the nowadays household should profit on maximum, is a low consumption or dual flush toilet.

Huge problem in kitchens is all the waste produced in there. Hence, a practical and sustainable solution should be used for the waste disposals. One of the smaller, simpler products reviewed is the NatureMill automatic indoor composter (figure 4), which serves as a kitchen garbage can: NatureMill uses 5 kWh/month of energy – less than a garbage truck would burn in diesel fuel to haul the same waste.
On figure 5 is shown another sustainable example for composting systems. It is original and well organized system which could be great solution for commercial kitchens.

Considering that the greatest amount of energy of a household is used in the kitchen a more sustainable solution for energy than the ordinary ones – gas, electricity and solid fuel, is needed. Therefore a solar battery (figure 2) can be installed to produce a completely sustainable energy which is also cost saving in long term.
One another solution for not developed countries could be the solar cooker (figure 3). Because of its qualities like simple construction, not expensive, easy installation and sustainability its popularity in the countries from the “third world” grows extremely fast in nowadays.
