Industrial Lubricants Go Green With Ricin And Cellulose
Researchers have developed an environmentally-friendly lubricating grease based on ricin oil and cellulose derivatives, according to the journal Green Chemistry. Bonus: the new formula does not include any of the contaminating components used to manufacture traditional industrial lubricants.
Its was indicated in the story otherwise so we can assume that is that same ricin mentioned in news reports and espionage thrillers extracted from the castor-oil manufacturing waste. Ricin oil does break down in the environment and adults are unlikely to eat a glob of lubricating oil so probably poses less of a threat then the reported millions of tons of petroleum derivatives and synthetic lubricants released into our waterways and oceans every year. Organic industrial lubricants are still in the research phase, but seem to hold a lot of promise.
NASA Satellite Shows Older Arctic Sea Ice Volume Cut By More Than Half In Just Last 4 Years
NASA scientist Jay Zwally said global warming is to blame. He said rapidly shrinking sea ice in the Arctic warms the rest of the globe indirectly. Older ice is more important in the Arctic because it is thicker, surviving the heat of summer and building over time.
First Hydrogen Fuel Cell-Powered Plane Takes to the Skies
Antares DLR-H2The world’s first plane powered solely by hydrogen fuel cells took off on its maiden flight Tuesday from Hamburg Airport in Germany. The Antares DLR-H2’s 10-minute flight showed off the plane’s 105-mph-speed capabilities and quiet electric glide motor. Eventually, the German Aerospace Center-sponsored Antares will be able to hit 300 mph.
Antares DLR-H2 world's first plane powered solely by hydrogen fuel cells
The most imminent plans for hydrogen fuel cells is for commercial aircraft as a source of auxiliary power. I wonder if hydrogen fuel cell powered drones wouldn’t make for good delivery vehicles for things like mail and packages.
