True Cost of Solar Hydrogen

The True Cost of Mobility?

and games, even our extensive music collections. We’re wired together and can keep tabs on each other at almost every moment of the day. In this issue, we feature several articles that focus on the technical breakthroughs that have allowed this revolution to happen and that are enabling even more sophisticated behaviors. But it would be remiss to focus on this topic without discussing privacy, ...

Thermochemical solar hydrogen generation.

Solar direct, indirect and hybrid thermochemical processes are presented for the generation of hydrogen and compared to alternate solar hydrogen processes. A hybrid solar thermal/electrochemical process combines efficient photovoltaics and concentrated excess sub-bandgap heat into highly efficient elevated temperature solar electrolysis of water and generation of H2 fuel utilizing the thermodyn...

The True Cost of Virtual Server Solutions

Our hands-on validation has revealed that VMware ESXi 3.5 can achieve a significantly higher VM density than Microsoft Hyper-V, allowing users to consolidate more servers on a VMware platform. While VMware’s advantage may not be surprising, given its 10-year history of leadership in this space, the magnitude of the difference is striking: VMware ESXi 3.5 demonstrated at least a 50% (1.5 to 1) d...
