Green Thermo Thursday TGIT – Thank Germanium It’s Thursday
Today I hard time choosing which G word we would thank. It was a toss up between Gallium and Germanium. These two elements represent the two rivalries on the European Continent –
The founders of the European Union are very happy as this proves that
The problem with germanium and gallium is that these are not abundant elements like silicon. While they may make more efficient PV cells it will be hard to compete on price with silicon based PV cells that can be fabricated from this much more abundant element. Silicon PV cells are typically 15% efficient so they too are much better at converting sunlight into energy than photosynthesis that is 0.1% efficient.
Last week I opined on liposuction. Well youtube has a video of a very fat cat from
Talking about fat cats Sir Richard Branson has entered the renewable fuel effort by having his test pilots fly a 747 jumbo jet from
There is some good thermodynamic news on using a biomass for something useful. Beet juice can be used to help roads from freezing in the winter. http://www.foxnews.com/story/0,2933,331739,00.html We all learned about solutes causing freezing point depression of water. This is great news for motorists and the department of transport as beet juice will not corrode metals like salt. I would have called this product beetheat but it was named geomelt instead.
The word of the day is fallible meaning prone to make mistakes. Sir Richard had proved he is also fallible as his Extra Virgin Coconut Oil relies on fallible experimentation.

fallible \FAL-uh-bul\, adjective:
1. Liable to make a mistake.
2. Liable to be inaccurate or erroneous.
Fallible derives from Medieval Latin fallibilis, from Latin fallere, "to deceive." It is related to fail, false (from falsum, the past participle of fallere), fallacy ("a false notion"), fault (from Old French falte, from fallere), and faucet (from Old Provençal falsar, "to falsify, to create a fault in, to bore through," from fallere).
