IBM modern Solar Collector for generate about 25kW of energy.

The challenges related to the access of energy and water, increasingly become importants and problematics for people, governments and the states. This means that the different governments have to invest essentials resources to tackle these problems.

At IBM, they talk about Modern solar collectors. This means: hundreds of
photovoltaic chips gathering energy at the center;  microchannel with each chip able to concentrate  2,000 times of the solar energy it would normally face, drinkable water and air conditioning. Pending to see a prototype, always use energy when it is necessary.
