9bef Bionavitas speeds algae growth with ‘light ro

Bionativas intends to license technology from other companies that are developing equipment specifically for harvesting.

Bionavitas speeds algae growth with 'light rods'

The Light Immersion Technology uses acrylic rods to bring light deeper into a pool of growing algae to maximize growth.

Weaver said the strategy at Bionavitas is to build its own refineries and to sell equipment. The company, which already has customers, intends to sell its bioreactors for both nutraceuticals and bioremediation this year.

For making biofuels in an outdoor pond, the rods float on the surface and bring sunlight in. The rods are shaped so that incoming light is reflected internally until it reaches the bottom and can penetrate out.

“I would much rather have someone with a stronger balance sheet than mine pay for the capital cost for a biofuels plant,” he said. “That’s why there are partnerships with established companies to go big.”

Bionavitas also intends to make algae oil for nutraceuticals, which offer higher margins than biofuels. Later this year, it’s planning to build an indoor closed bioreactor in Redmond, Wash., which will use dozens of light rods on the surface of a vat of algae. Instead of sunlight, the company intends to use red and blue LED lights, which will flicker to save on energy costs, Weaver said.

In addition to biofuels and nutraceuticals, Bionavitas intends to sell equipment to use algae for bioremediation, such as removing toxic substances from waste water, Weaver said.

“There are a lot of companies developing processes for growing algae. But there’s a fundamental flaw to all those. You quickly become light-constrained, which is why you don’t have massive growth,” he said. “So it’s all well and good to modify genes or find a special strain, but if you can’t grow a large mass, you got nothing.”

Misconceptions

Reacting to his stepping down, Lord Robert Winston, professor of science and society at Imperial College London, said: “I fear that in this action the Royal Society may have only diminished itself.
“This is not a good day for the reputation of science or scientists.
“This individual was arguing that we should engage with and address public misconceptions about science – something that the Royal Society should applaud.”
Dr Roland Jackson, chief executive of the British Association for the Advancement of Science, said Prof Reiss’s departure was a “real loss”.
“I was at the actual discussion and what I heard him say , however it has been reported, was essentially the position advocated by the Royal Society,” he said.
Dr Jackson said the organisation “should have supported him and used this opportunity to further a reasoned debate”.
Professor Chris Higgins, vice-chancellor of the University of Durham, said: “There should be no room for doubt – creationism is completely unsupportable as a theory, and the only reason to mention creationism in schools is to enable teachers to demonstrate why the idea is scientific nonsense and has no basis in evidence or rational thought.”
Professor Michael Reiss has quit as director of education at the Royal Society following the controversy over his recent comments on creationism.
Last week Prof Reiss – a Church of England minister – said creationism should be discussed in science lessons if pupils raised the issue.
He was criticised by other scientists – though misquoted as saying creationism should be “taught” in science classes.
The society said some of his comments had been “open to misinterpretation”.
This had damaged its reputation.

Anger over Joseph choir contest

The BBC has now ended a controversial school choir contest that is said to have left many children disappointed.
Choirs were invited to upload videos of themselves to a website, in a contest alongside the TV talent search for a new Joseph for the West End musical.
People could then rate the choirs online. But there have been complaints about problems with the system, which even had to be suspended for a time.
The BBC has accused some of unfairly trying to boost their choir’s chances.
When it reinstated the voting system last Monday, it then insisted people must register to take part.
Explaining this, the programme makers said they had been “amazed by the high levels of rating and the lengths that people will take to improve their choir’s ranking”.
“Asking you to login and verify your e-mail address acts as an extra deterrent for those trying to break the rules of the competition.”

Repeat votes

Schools were ranked on the average rating they got, from five for excellent to one for poor – not simply how many votes they picked up.
Some people might have misunderstood what they had to do.
“When you rate, you need only click on one multicoloured coat,” the website explained.
“So, for example, if you wish to rate the choir a four, you click on the fourth coat along in the row. You should not click coats one, two, three and four.”
But there have also been claims that people not only repeatedly gave their own choir the highest rating, but also repeatedly gave a low rating to competitors.
In their “frequently asked questions”, the producers said it had been “far more popular than we anticipated”, with hundreds of votes per minute straining the database.
In answer to the question, How come I can vote more than once? they say: “We identify voters via a bunch of different measures. Some of these measures take place after you’ve voted.
“Periodically, we sweep the database to remove votes for the same choir that we believe come from the same person.
“This system isn’t perfect, but we have gone to considerable lengths to ensure it is a fair as possible and we believe it is generating accurate results.”

Grease victory

Mead is one of three performers who won West End roles on Saturday night.
Earlier in the evening, Danny Bayne and Susan McFadden were crowned the winners of ITV1’s Grease Is The Word.
The duo, who were also picked by a public phone vote, will take the lead roles of Danny and Sandy in a Piccadilly Theatre production of Grease starting on 8 August.
McFadden, 24, from Dublin, is the sister of former Westlife singer Brian McFadden.
She told presenter Zoe Ball: “I can’t wait. I’ve waited so long to get here.”
Bayne, 19, from Welling, south London, beat Anthony Kavanagh – who had two Top 10 hits in the 1990s under the name Kavana.
Any Dream Will Do and Grease Is The Word have been pitched against each other in a ratings battle.
But the BBC’s show has been the winner in the ratings so far, with 4.9 million watching last Saturday’s Any Dream Will Do compared with Grease is the Word’s 2.9 million viewers.
Booking has already opened for both productions

Inquiry call

The losses caused a shortage of men within the clan which lasted for several generations.
Mr McRae said: “It has been suggested that a metal detector survey could be carried out to identify artefacts and human remains and any that are found be dug up under
the supervision of an archaeologist.
“We don’t think it should be dug up at all.”
The clan society, and others concerned by what may happen to the battlefield, have staged a number of protest marches in the area to raise awareness of the issue.
“We would like to see the pylons routed right round the battlefield with no disturbance to the ground and no disturbance to the remains of the men who have lain here
for all that time,” he said.
“A lot of people don’t know there was a battle here and a lot don’t know what is planned here. A public inquiry will bring this to people’s attention.”
In a statement, Scottish and Southern Energy said: “We continue to believe we have submitted a robust application and SSE will make a fully informed decision about the
route of the proposed overhead transmission line and its potential impact on the landscape and archaeology related to this area of historical interest.”
