Comments Off on Startup is developing kelp farms in the open ocean to make carbon-neutral biofuel

Could a robotic kelp farm offer an alternative fuel for cars or jets? The founders behind Marine BioEnergy hope so. The startup will soon begin testing a prototype of their kelp elevator, a farm that can move up and down in the water with the help of drones to optimize access to sunlight and nutrients, near Catalina Island in California . They think biofuel made from the kelp could be cost-competitive with fossil fuels . Marine BioEnergy’s new kelp elevator grows seaweed on a long tube, and if tests go well, they hope to start farming in the open ocean between Hawaii and California. They’re working with the Pacific Northwest National Laboratory , which has developed a way to transform kelp into biocrude. The kelp fuel should be carbon neutral since kelp absorbs around the same amount of carbon dioxide as would be emitted when the fuel is burned.

Marine BioEnergy has also been working with the University of Southern California’s Wrigley Institute for Environmental Studies on a proof-of-concept study. Kelp could provide a better biofuel: it has little cellulose or lignin, fibers that are hard to process. Grown in the ocean, kelp also wouldn’t require pesticides or irrigation as plants on land might. In optimal conditions, it can grow over a foot a day. And the kelp elevator could help the seaweed reach those conditions, even in the open ocean. Kelp grows best in shallow coastal waters, where it can anchor to the ocean floor and receive sunlight. But to scale up kelp production, Marine BioEnergy would need the space of the open ocean. Their robotic elevator could help kelp receive the sunlight, from near the ocean’s surface, and nutrients, from deeper waters, to thrive. Drones could also keep the kelp elevator avoid storms and stay out of the way of ships, and when the seaweed is ready, tow it to a ship. The team is trying to determine whether it might be more economical to make the biocrude right on the ship since a processing center could fit on a container ship powered by the fuel. + Marine BioEnergy Via Fast Company Images via USC Wrigley Institute for Environmental Studies Facebook

Florence is the largest asteroid to pass Earth in a century

Comments Off on Florence is the largest asteroid to pass Earth in a century

Though the American eclipse may have come and gone, the skies above Earth never cease to amaze with new interstellar events. Early this morning, according to NASA, Florence became the largest asteroid to approach our planet in over a century. The asteroid measures 2.7 miles (4.4 km) in diameter and passed by from the relative proximity of 4.4 million miles (7 million km) away from Earth, roughly 18 times the average distance between the Earth and the Moon. Although other asteroids have traveled closer to Earth in the past, none were as massive as Florence, the largest near-Earth asteroid ever tracked by NASA. Florence, like all asteroids in our solar system , formed out of the debris left behind after the formation of the planets and the sun . It was originally discovered by Schelte “Bobby” Bus at Siding Spring Observatory in Australia in 1981 and named after Florence Nightingale, the founder of modern nursing and pioneering statistician and social reformer. Florence’s trip near Earth, its closest since 1890, provided scientists with a unique opportunity to study the ancient asteroid.

Amateur astronomers also observed the asteroid, which was relatively easy to spot since it reflects 20 percent of sunlight that reaches its surface, in contrast to only 12 percent reflection from the Moon . Scientists project that Florence will not come this close to Earth again until 2500. Via BBC Images via NASA (1) , (2)

Comments Off on Sundrop Fuels Uses Concentrated Solar Heat to Vaporize Biomass

The technology sounds ultra-futuristic: concentrated solar heat that can vaporize biomass (wood, crop waste, etc.) into synthetic fuels . But the process, developed by Sundrop Fuels , is real, and it can produce twice the amount of gasoline or diesel than conventional biomass gasification systems.
