We scan the digital environment to examine the leading trends in emerging technology today to know more about future.

We have added a few indices around the site. Though we look to the future, we need to keep an eye on the present as well:

World’s first hybrid wind/current generator could generate double the power | Treehugger

Combining a three-bladed Darrieus turbine on top, a Savonius turbine underneath, and a generator in between, the SKWID power generation concept is claimed to be the world’s first hybrid system “capable of maximizing the harvesting of ocean energy from wind and current”.

This little critter could be fueling your car one day. A look at this potential biofuel.


One Marine Animal Could Be Next Biofuel

Scientists are looking to the ocean for the next big thing in renewable sources of biofuel for your eco-car.

 Five researchers at the University of Bergen (UiB) and Uni Research say they found the marine animal tunicatecould be used as a renewable source of biofuel. These marine animals serve as bacteria eaters and as a foodstuff in Korea and Japan right now, but the cellulose, the protein and the Omega-3 fatty acids in tunicate are the cause for its many uses.

“Its mantle consists of cellulose, which is a collection of sugars. When cellulose is cleaved, one can obtain ethanol. And ethanol can be used for biofuel in cars. The animal’s body consists of large amounts of protein and Omega-3. This can be used for fish feed,” says Professor Eric Thompson at UiB’s Department of Biology.

The researchers say they have already acquired a patent for biofuel and have a patent application pending for the cultivation of tunicate as fish feed.

Dr. Sc. Christofer Troedsson of Uni Research’s Molecular Ecology Group and head of the research at UiB’s Marine Development Biology and the tunicate research project said the bioethanol used today is unsustainable, as it comes from foods already used for human consumption.

“That is why there has been a move towards using cellulose from the timber industry to produce bioethanol,” Troedsson said. “However, it is quite complicated to break down the cellulose in trees and convert it into ethanol. This is because the wood contains a substance called lignin, which is hard to separate from the cellulose. Tunicates contain no lignin. Their cellulose is also low in crystals and is more efficiently converted into ethanol.”

He said using tunicate rather than trees is more environmentally friendly because it does not occupy large tracts of land that could be used for other purposes.

An advance in the field of biofuels.



In the search for renewable alternatives to gasoline, heavy alcohols such as isobutanol are promising candidates.

They contain more energy than ethanol and are also more compatible with existing gasoline-based infrastructure.

For isobutanol to become practical, however, scientists need a way to reliably produce huge quantities of it from renewable sources.

MIT chemical engineers and biologists have now devised a way to dramatically boost isobutanol production in yeast, which naturally make it in small amounts. They engineered yeast so that isobutanol synthesis takes place entirely within mitochondria, cell structures that generate energy and also host many biosynthetic pathways. Using this approach, they were able to boost isobutanol production by about 260 percent.

Though still short of the scale needed for industrial production, the advance suggests that this is a promising approach to engineering not only isobutanol but other useful chemicals as well, says Gregory Stephanopoulos, an MIT professor of chemical engineering and one of the senior authors of a paper describing the work in the Feb. 17 online edition of Nature Biotechnology

Wind Turbine: At 75m this wind turbines blades as massive.


A single of these giant wind turbine blades produced by German manufactuer Siemens is almost as big as the wingspan of an Airbus A380, the world’s largest airliner. At 75 meters (246 feet), this massive beast is destined for a prototype 6-megawatt turbine to be erected at Denmark’s Østerild test station.

Soon new power plants? (Sorry, I couldn´t resist that one).


Secrets of the First Practical Artificial Leaf

A detailed description of development of the first practical artificial leaf— a milestone in the drive for sustainable energy that mimics photosynthesis— appears in the ACS journal Accounts of Chemical Research. The article notes that unlike earlier devices, which used costly ingredients, the new device is made from inexpensive materials and employs low-cost engineering and manufacturing processes.

Daniel Nocera of MIT points out that the artificial leaf responds to the vision of a famous Italian chemist who, in 1912, predicted that scientists one day would uncover the “guarded secret of plants.” The most important of those, Nocera says, is the process that splits water into hydrogen and oxygen. The artificial leaf has a sunlight collector sandwiched between two films that generate oxygen and hydrogen gas. When dropped into a jar of water in the sunlight, it bubbles away, releasing hydrogen that can be used in fuel cells to make electricity. These self-contained units are attractive for making fuel for electricity in remote places and the developing world, but designs demonstrated thus far rely on metals like platinum and manufacturing processes that make them cost-prohibitive.
