NASA – Growing algae underwater?

NASA Ames Research Center makes biofuel from wastewater..

NASA has thrown its weight behind a clever method of growing algae in wastewater for the purpose of making biofuel.onathan Trent, a bioengineer at NASA Ames Research Center in Moffett Field, Calif comments that the forward-osmosis membranes OMEGA only release fresh water into the ocean, and dont permit salty water to contaminate the bags.

Such a process would mainly rely on the energy of the ocean waves to mix the algae, as well as sunlight and carbon dioxide. The offshore locations and the wide oceans would also have more than enough room to grow massive amounts of algae needed to produce biofuels for an energy-hungry world.

One possible future plan would combine the algae-growth system with a gigantic offshore wind farm being built by Germany, Sweden and Denmark. Wind power could then provide lights to keep algae growing underwater and during the nighttime hours – a fitting vision for the sustainable future of spaceship Earth.

Its renewable carbon negative fuel from algae making use of sunlight,sewage and co2-a solution for today’s problem!

Algae may fix Logan’s sewage mess

“It’s like killing two birds with one stone,” said Paul Israelsen, a research associate professor in USU’s electrical and computer engineering department. The algae cultivated in the lagoons is to be converted to methane and used as fuel for electrical generation and the phosphorus would be extracted to sell to fertilizer manufacturers and other industries.

Gene modification of Bacteria turns Biofuel production competitive

Researchers from the UCLA Henry Samueli  School of Engineering and Applied Science have genetically modified a cyanobacterium to consume carbon dioxide and produce the liquid fuel isobutanol, which holds great potential as a gasoline alternative. The reaction is powered directly by energy from sunlight, through photosynthesis.

This new approach avoids the need for biomass deconstruction, either in the case of cellulosic biomass or algal biomass, which is a major economic barrier for biofuel production,” said team leader James C. Liao, Chancellor’s Professor of Chemical and Biomolecular Engineering at UCLA. Hence this method is more efficient and less expensive.

How Dinoflagellates Protect Themselves during Photosynthesis

During photosynthesis at high light intensities dangerous oxygen radicals can form inside cells. Dinoflagellates have a unique light-harvesting complex (antenna) which can divert superfluous energy extremely efficiently to avoid this cell damage. In cooperation with colleagues in the USA and the Czech Republic, a team of biophysicists from the Ruhr-University Bochum around Prof. Eckhard Hofmann and Tim Schulte has now been able to determine which molecules in the antenna are of significance.
