Glad to see so much interest on Slashdot for our sunflower. I'd like to address a few misunderstandings and share with you how YOU can test one of our systems in your home town.
1. The standard commercial system will be available in 2017 for both heat and electricity, the water desalination will come later.
2. This presentation explains the science behind the sunflower and how it can also provide cooling:

By means of a thermally driven sorption chiller, cool air can also be produced. A sorption chiller is a device that converts heat into cooling via a thermal cycle applied to a liquid or solid sorption material. Adsorption chillers, with solid silica gel adsorbers and with water as a working fluid, can replace compression chillers, which place a burden on electrical grids in hot climates and contain working fluids that are harmful to the ozone layer. Although absorption (liquid sorption) systems are already available for combination with the HCPVT system, they provide less cooling output compared to low-temperature driving heat for the adsorption (solid sorption) systems under development at IBM. The systems can also be customized with a transparent back for urban installations.
3. This presentation highlights the regions and the commercial applications:

4. Here is a YouTube video showing the prototype in Biasca, Switzerland

5. The news was announced at a TED conference in San Francisco on Tuesday. You can watch the presentation here:
