Give me sunshine and CO2 and I'll make a highly useful and convenient energy source. Sounds too good to be true? Well it isn't. You can kiss climate change goodbye, thanks to a blue-green algae from the ocean.
Umm...that is if all the kinks can be worked out. But hey, it's a great concept that deserves a chance.
Scientists produced genetically modified cyanobacteria that convert sunlight and CO2 into glucose, sucrose, and cellulose that are readily convertible into ethanol. If development goes well, algal ethanol (Alganol?) can be produced using much less land and far fewer resources than corn-based ethanol production.
