Magnifying sun by 2000 times is better but as long as batteries are needed to store energy, we are not yet out of the woods...

IBM Solar Collector Magnifies Sun By 2000X – These Could Provide Power To The Entire Planet -
A team at IBM recently developed what they call a High Concentration Photo Voltaic Thermal (HCPVT) system that is capable of concentrating the power of 2,000 suns, they are even claiming to be able to concentrate energy safely up to 5,000X, that’s huge.
The process of trapping the sunlight produces water that can be used to produce filtered drinkable water, or used for other things like air conditioning etc. Scientists envision that the HCPVT system could provide sustainable energy and fresh water to communities all around the world.
“Each 1cmX1cm chip can convert 200-250 watts, on average, over a typical eight-hour day in a sunny region. In the HCPVT system, instead of heating a building, the 90 degree Celsius water will pass through a porous membrane distillation system where it is then vaporized and desalinated. Such a system could provide 30-40 liters of drinkable water per square meter of receiver area per day, while still generating electricity with a more than 25 percent yield or two kilowatts hours per day. A large installation would provide enough water for a small town.” (2)
The heat is absorbed into hundreds of tiny solar cells called photovoltaic chips. These gather the energy and are then cooled by microchannled water, which is why they are safely able to concentrate such large amounts of solar energy.
