 Algae 1 naturally produce oil, when its process start with oil turned into bio fuels, an alternative energy source. This is just one snag. Harvesting the oil from algae-float water is prohibitively expensive. But researchers have come up with an effort best solution. Bubbles, smaller than the width of human hair, can help reduce the costs of collecting algae oil. So-called micro-bubbles are already used for water purification. They surround the contaminants and float them out of the liquid. Similarly, in water containing algae, bubbles can float the algae to the surface for easy collection and processing. The research builds on previous work that use micro bubbles to grow algae more densely 2, and thus increase production. This time, however, the researchers produce the business with a new method that use the spotless energy and is cheaper to instore. The studies in the bio-technology and bio-engineering. Although micro-bubbles improve algae harvesting in the lab, they still afterwards get larger scales. The researchers are planning a pilot program, for an algae-bio fuel plant, in the hope of making really green energy.
