Wind turbines can rotate on either a horizontal or vertical axis. To date, there have not been too many deployments of vertical-axis wind turbines off-shore, they have tended to be use in more urban areas. However, Norway is home to a number of pilots testing various vertical axis designs off-shore, including this one. Benefits of this design include:-- no need to track the wind- maintenance is easier as all the gear is at the base of the tower, not the top- can be placed closer together = more energy/less space- reduced risk of bird strike https://electrek.co/2023/01/27/norway-vertical-axis-floating-wind-turbine/
Heavy vehicles need fuels which provide high energy density for as little space as possible and which can be replaced quickly once depleted. Hydrogen is being looked at as an option to replace diesel, but it has numerous disadvantages as a gas or liquid which need to be managed. Ammonia (NH3) as a H2 carrier is however much easier to handle than H2 and still provides many times the energy density of batteries.https://amogy.co/amogy-presents-worlds-first-ammonia-powered-zero-emission-semi-truck/
The negative CO2 emission, micro-plastic, landfill and other environmental impacts of the textile and concrete sectors are significant. But what if by taking fibre waste from carpets and using it to make concrete you could reduce the negative impacts of both sectors?After 7 years of research this is exactly what researchers out of the Institute for Frontier Materials (IFM) have achieved.FibreCrete 100, is a carpet fibre-reinforced concrete that can be applied to driveways, footpaths, cycle paths and industrial hardstand areas. Even better, the inclusion of carpet fibres appears to make the concrete less prone to cracking.https://ifm.deakin.edu.au/2022/10/geelong-research-collaboration-creates-australias-first-waste-carpet-sol
Bin-e, invented by a Polish company for public spaces (think your local food court), uses artificial intelligence-based object recognition to automatically sort recyclables (glass, paper, plastic and metal) into separate compartments. After sorting, the machine compresses the paper/plastic waste, monitors how full each compartment is and sends an alert when a pick-up is needed so you are not wasting time, money & fuel on partial pick-ups.https://www.bine.world
Constructing offshore winds farms is a complicated business, especially when all your equipment and supplies have to travel through a single, near-by Port.The Port of Esbjerg, in Denmark is a port which already specialises in port services for the offshore wind industry. They have specialised facilities and flexible areas for transporting, pre-assembling, shipping out and servicing large offshore wind turbines. But even a highly specialised Port can potentially manage their facilities better. A digital twin is helping the Port understand changes they can make which could triple their throughput within the next two years. Impressive!https://renews.biz/83139/digital-twin-could-help-port-esbjerg-triple-capacity/
