Drone saves swimmers in danger
When a group of swimmers on the Spanish coast near Valencia got into trouble because of an undercurrent, they were saved by a drone.
Improved lithium battery doesn't burst into flames
Researchers claim to have solved an old problem: lithium batteries bursting into flames. This means it will be possible again to use batteries with a larger capacity than the current ion models, following a period when lithium batteries were out of favour because of the fire hazard they posed.
'Poop bacteria' reproduce the Mona Lisa
In order to show what’s possible with single-celled organisms that can be controlled with light, Italian scientists have reproduced a version of Leonardo da Vinci's masterpiece the Mona Lisa using E. coli bacteria.
Electric Superbike Twente wins first race
Last weekend, the students of Electric Superbike Twente won their first race on their electric motorbike. During a race at Donington Park in Great Britain between petrol and electric motorbikes, rider Thijs Peeters finished third overall and first of the electric bikes.
Asphalt could be made even quieter
The noise of tyres on asphalt is a nuisance for people who live close to a main road. But there's good news: asphalt could be made even quieter by adjusting the size of the pores in the asphalt, the thickness of the layer of asphalt and the smoothness of the surface. This has been demonstrated by the doctoral research of Marieke Bezemer-Krijnen at the University of Twente.
Probe to study the Sun’s immediate surroundings
Tomorrow, NASA’s Parker Solar Probe will leave Earth and head towards the bizarrely hot area surrounding the Sun. The probe will carry four packages of high-tech measuring equipment, with the objective of solving a number of questions about this zone.
Paint gun for measuring photocatalytic coatings
The Fraunhofer-Gesellschaft's Institute for Surface Engineering and Thin Films IST in Germany has created a device for testing photocatalytic coatings. These coatings often fail to work properly, and no one is entirely sure why. This invention is designed to change that situation.
IJsselmeer to get large wind farm
In the IJsselmeer lake, construction company Van Oord and wind turbine manufacturer Siemens Gamesa are to build a wind farm of 86 turbines, with a combined capacity of 380 MW. A temporary artificial island will be turned into a nature reserve once the work has been completed.
Can our delta cope with the drought?
We spend millions on protecting the country against flooding, and we're now suddenly faced with one of the driest summers ever recorded. Is our water management adequately prepared?
Trial with alternative wind turbine foundations
Next year, offshore concern Van Oord will be installing commercial 'suction buckets' at a wind farm in Germany. Two of the 33 piles will be fitted with this unusual foundation type, which uses much less material and energy.
Amsterdam scores well on sustainable transport
Amsterdam is Europe's most sustainable city after Copenhagen when it comes to transport. The capital owes that position above all to the high proportion of cyclists and pedestrians in its transport mix. However, for public transport the city actually gets the lowest score.
Consider thermal stress when repurposing office buildings
It sounds great, converting an empty office building into apartments. Until we ‘enjoy’ such a hot summer, and you discover that you've landed on a heat island, at least that's what engineering consultancy BOOT suggests with its thermal stress map.
Transformer platform substructure to go seaward
The substructure of the first transformer platform for the new Borssele offshore wind farm is ready. This Sunday, the 50-metre-high colossus will be towed out to sea and erected in position.
Organically formed concrete floor over fifty percent lighter
The organically formed concrete floor for an experimental house of Swiss technical university ETH weighs less than half as much as a conventional version. What's more, it looks great too. This floor has been made possible using design software and 3D printing.
Ocean Cleanup design updated once again
The Ocean Cleanup plastic clearance operation has modified its design for the final time before it goes operational. The new plastic capturing system will float through the ocean currents faster than the plastic flows, and will no longer be anchored.
