Following a $200 million investment this summer — the largest agriculture-tech funding round in history — vertical farming startup Plenty is expanding beyond its Bay Area roots.

The company is opening a second farm in the greater Seattle area, Plenty CEO Matt Barnard told Business Insider. Located in Kent, Washington, the 100,000-square-foot warehouse facility will grow 4.5 million pounds of greens annually, which is enough to feed around 183,600 Americans, according to the USDA.

The new farm will officially start production in spring 2018. Instead of growing outdoors, Plenty grows its crops on glowing, LED-lit 20-foot-tall towers inside a former electronics distribution center in South San Francisco. The towers do not require soil, pesticides, or even natural sunlight.

Citizens’ Assembly hears how Denmark became one of most efficient countries in world.

A two-in-one solar bio-battery and solar panel has been created by researchers who printed living cyanobacteria and circuitry onto paper.

Cyanobacteria are photosynthetic micro-organisms that have been on Earth for billions of years. They are thought to be the primary reason why the Earth’s atmosphere is oxygen rich.

Now, a team has demonstrated that cyanobacteria could be used as an ink and printed from an inkjet printer in precise patterns onto electrically conductive carbon nanotubes, which were also inkjet-printed onto the piece of paper. The team showed that the cyanobacteria survived the printing process and were able to perform photosynthesis so that small amounts of electrical energy could be harvested over a period of 100 hours.

A long way to go but potentially well worth the R&D.

Transparent solar cells started to emerge in the last 5–6 years, but there are already some live installations of this tech with impressive performance.

I was thinking about this thing, and the one in Iceland. Maybe we could build giant blimps in the atmosphere of Venus, it would carry that machine on its belly, and on the back of the blimp super advanced solar panels. Then inside of the blimp the CO₂ could be mixed into liquid crystals or something like that and be dropped like rain down on the surface, to eventually terraform it.

Global Engineering — a phrase that describes steadying the world’s climate with technical solutions. A Swiss company has received EU funding to develop a machine that captures CO₂. Can it really make a difference?

Humanity has sought to make the Earth’s oceans potable for thousands of years. The Norse tale of Utgarda-Loki tells of Odin being tricked into drinking from a horn connected to the sea, while Exodus 15:22–26 of the Bible likely describes Moses desalinating the water of Marah:

When they came to Marah, they could not drink the water of Marah because it was bitter; therefore it was named Marah. And the people grumbled against Moses, saying, “What shall we drink?” And he cried to the Lord, and the Lord showed him a log, and he threw it into the water, and the water became sweet.

PROFITABLY recycling waste is always a good idea. And the Allen Institute for Brain Science, in Seattle, has found a way to recycle what is perhaps the most valuable waste of all—living human brain tissue. Understandably, few people are willing to donate parts of their brains to science while they are still alive. But, by collaborating with seven local neurosurgeons, the institute’s chief scientist, Christof Koch, and his colleagues, have managed to round up specimens of healthy tissue removed by those surgeons in order to get to unhealthy parts beyond them, which needed surgical ministration. Normally, such tissue would be disposed of as waste. Instead, Dr Koch is making good use of it.

The repository the cells from these samples end up in is a part of a wider project, the Allen Cell Types Database. The first data from the newly collected human brain cells were released on October 25th. The Allen database, which is open for anyone to search, thus now includes information on the shape, electrical activity and gene activity of individual human neurons. The electrical data are from 300 live neurons of various types, taken from 36 people. The shapes (see picture for example) are from 100 of these neurons. The gene-expression data come from 16,000 neurons, though those cells are post-mortem samples.

The human brain is the most complex object in the known universe. Because it is more complicated than animal brains in ways that (say) human livers are not more complicated than animal livers, using animal brains as analogues of human ones is never going to be satisfactory. Dr Koch’s new database may therefore help explain what is special about human brains. That will assist understanding of brain diseases and disorders. It may also shed light on one of his particular interests, the nature of consciousness.

A WISE driver keeps an eye on the fuel gauge, to make timely stops at filling stations. For drivers of electric cars, though, those stations are few and far between. The infrastructure needed for refilling batteries has yet to be developed, and the technology which that infrastructure will use is still up for grabs. Most electric cars are fitted with plugs. But plugs and their associated cables and charging points bring problems. The cables are trip hazards. The charging points add to street clutter. And the copper wire involved is an invitation to thieves. Many engineers would therefore like to develop a second way of charging electric vehicles—one that is wireless and can thus be buried underground.

Electrical induction, the underlying principle behind wireless charging, was discovered by Michael Faraday in 1831, and is widely used in things such as electric motors and generators. Faraday observed that moving a conductor through a magnetic field induced a current in that conductor. Subsequent investigations showed that this also works if the conductor is stationary and the magnetic field is moving. Since electric currents generate magnetic fields, and if the current alternates so does the field, an alternating current creates a field that is continuously moving. This means that running such a current through a conductor will induce a similar current in another, nearby, conductor. That induced current can then be used for whatever purpose an engineer chooses.

Imagine printing off a wristband that charges your smartphone or electric car with cheap supplies from a local hardware store.

That’s the direction materials research is heading at Brunel University London where scientists have become the first to simply and affordably 3D print a flexible, wearable ‘battery’.

The technique opens the way for novel designs for super-efficient, wearable power for phones, electric cars, medical implants like pacemakers and more.
