As America looks for new alternative fuel sources, biodiesel from algae offers a new and innovative solution. America uses 180 billion gallons of oil for transportation systems and it is starting to harm the Earth. Wind, solar, and hydrogen energy forms are impractical due to size, scale, and cost of locations. This video discusses how the best alternative fuel is bio-fuel. Ethanol’s from corn and crop based biodiesel have positive net energy yields and release less CO2 than oil, however these sources are less efficient. We need to go back to oils origin. Algae require less input, can be grown anywhere, and does not strain food prices. Some strains of algae can refined to biodiesel. Algae production is shown through a vertical system, which is called Vertigro, which produces a large amount of algae. Good quality of video, middle school level video. Run time 03:32.
