'Apollo Program' For Hydrogen Energy Needed, Stanford Researcher Says - SpaceDaily What if all the vehicles now on the road in the United States were suddenly powered by hydrogen fuel cells? Wind is the most promising means of generating hydrogen, said Jacobson, who with former postdoctoral fellow Cristina Archer recently published a study that mapped global winds and showed the world, especially the United States, has more than enough wind to meet all its energy needs. Jacobson envisions wind turbines generating electricity on wind farms that are linked in a network to ensure energy production even when parts of the grid have windless days. The electricity would travel through transmission lines to a filling station--similar to today's gas stations. There, it would enter an electrolyzer, passing through water and splitting it into oxygen, which would be released into the air, and hydrogen, which would get compressed and stored. |

Adsorbent Materials For Storing Hydrogen - SpaceDaily The mentioned research team has commenced work on three families of materials: activated carbons, zeolites and stacked clays. These materials fulfil four requisites: they have mechanical resistance and are safe, apart from being light and cheap. Storage based on physiadsorbtion provides a potentially higher energy efficiency than the rest of the mentioned storage options, given that the hydrogen is retained at a low temperature and 100% of the hydrogen adsorbed can be recovered. The low boiling point of hydrogen (-253ºC) makes it necessary to employ temperatures of about -196ºC. |

NASA, Xerox To Demonstrate 'Virtual Crew Assistant' - SpaceDaily "Clarissa is a fully voice-operated 'virtual crew assistant,' enabling astronauts to be more efficient with their hands and eyes and to give full attention to the task while they navigate through the procedure using spoken commands," said Beth Ann Hockey, project lead on the team that developed Clarissa at NASA Ames. Clarissa is 'hands-free' and responds to astronauts' voice commands, reading procedure steps out loud as they work, helping keep track of which steps have been completed, and supporting flexible, voice-activated alarms and timers. |
