Danish invention could revolutionise wind energy

New wind turbine foundation more affordable and easier on wildlife

Danish researchers from Aalborg University have come up with an ingenious concept that could potentially make utilising wind energy far more sustainable and affordable in the future.

The invention, which is called ‘Sugebøtten’ (‘Mono Bucket’), attaches itself to a lake or seabed using pressure from a vacuum pump and thus avoids being hammered down into the bottom and disturbing the vulnerable habitat of the marine wildlife.

Aalborg-based company Universal Foundation recently signed an agreement to use the new technology in a massive US wind energy project in Lake Erie near Cleveland, Ohio.

“It’s the most effective and sound-proof foundation for offshore wind turbines,” Kristian Ravn, the head of Universal Foundation, told Børsen newspaper.

“Today, there is a lot of focus on noise and its impact on marine mammals.”

Europe next
The Lake Erie project is worth around 780 million kroner and will implement the Danish tech to secure the wind turbines to the bottom of the lake.

Ravn expects the new tech, which can be up to 30 percent cheaper than the traditionally-fixed foundations, to be used in a similar project in Europe in the near future.

Of Denmark’s total exports in 2015, 11 percent came from energy technology.

A survey carried out by Megafon for TV2 has found that 71 percent of parents have handed over children to daycare in spite of them being sick.

Moreover, 21 percent of those surveyed admitted to medicating their kids with paracetamol, such as Panodil, before sending them to school.

The FOLA parents’ organisation is shocked by the findings.

“I think it is absolutely crazy. It simply cannot be that a child goes to school sick and plays with lots of other children. Then we are faced with the fact that they will infect the whole institution,” said FOLA chair Signe Nielsen.

Pill pushers
At the Børnehuset daycare institution in Silkeborg a meeting was called where parents were implored not to bring their sick children to school.

At Børnehuset there are fears that parents prefer to pack their kids off with a pill without informing teachers.

“We occasionally have children who that they have had a pill for breakfast,” said headteacher Susanne Bødker. “You might think that it is a Panodil more than a vitamin pill, if it is a child who has just been sick, for example.”

Parents sick and tired
Parents, when confronted, often cite pressure at work as a reason for not being able to stay at home with their children.

Many declare that they simply cannot take another day off, as they are afraid of being fired.

Allan Randrup Thomsen, a professor of virology at KU, has heavily criticised the parents’ actions, describing the current situation as a “vicious circle”.

“It promotes the spread of viruses, and it adds momentum to a cycle where parents are pressured by high levels of sick-leave. If they then choose to send the children to daycare while they are still recovering, they keep the epidemic going in daycares, and this in turn puts a greater burden on the parents.”
