Unmanned boats and drones could repair offshore wind farms and clean up the sea

Unmanned boats and drones could repair offshore wind farms and clean up the sea

Technology
Autonomous drones and unmanned boats could be used to maintain the UK's offshore wind farms in the next five years, experts have told Sky News.A team of scientists from the University of Bristol and French-based engineering and science firm Thales are testing technology that will eventually remove the need for humans to carry out the dangerous role. The process involves AI (artificial intelligence) boats carrying autonomous drones out to wind turbines at sea, before they take off and land on turbine blades and carry out repairs.Tom Richardson, from the University of Bristol who is leading the team, said: "The number of turbines we have is almost growing exponentially.

Boris Johnson: Wind farms could power every home by 2030

Boris Johnson: Wind farms could power every home by 2030

Science
Offshore wind farms will generate enough electricity to power every home in the UK within a decade, Boris Johnson has pledged.Speaking to the Conservative party conference, the PM announced £160m to upgrade ports and factories for building turbines to help the country "build back greener". The plan aims to create 2,000 jobs in construction and support 60,000 more.He said the UK would become "the world leader in clean wind energy". "Your kettle, your washing machine, your cooker, your heating, your plug-in electric vehicle - the whole lot of them will get their juice cleanly and without guilt from the breezes that blow around these islands," he said.Mr Johnson's speech comes after he made a pledge at a UN biodiversity summit in New York to protect 30% of U...
Climate change: Pledge to cut emissions from dairy farms

Climate change: Pledge to cut emissions from dairy farms

Science
A dairy firm is pledging to make its operations carbon-neutral from cow to supermarket by 2050, including more than 2,000 farms in the UK. This will require "radical changes" over the coming decades, including developing new technologies, the dairy co-operative, Arla Foods, said.It admitted the target was "ambitious", but said it was achievable.However, the Vegan Society said there was no way to make dairy a climate-friendly product.Gases which help to heat the atmosphere and contribute to climate change are a by-product of the dairy industry. They include direct emissions of methane, a potent greenhouse gas, from cows, and carbon dioxide and nitrous oxide from the likes of packaging, transportation and fertilisers. Arla, the lar...
Greenhouse gas emissions on rice farms underestimated, study finds

Greenhouse gas emissions on rice farms underestimated, study finds

Science
Sept. 10 (UPI) -- Climate scientists and policy makers have underestimated the amount of greenhouse gas emitted by rice farms. New research showed rice farms emit significant amounts of nitrous oxide in addition to methane. In recent years, policy makers have worked with rice farmers to reduce methane emissions and conserve water resources by deploying intermittent flooding. As water resources become more scarce, more continually flooded rice farms are likely to adopt intermittent flooding methods. But new research -- published this week in the journal Proceedings. of the National Academy of Sciences -- suggests the reduction in methane emissions achieved by intermittent flooding is undermined by increases in nitrous oxide emissions. "Water management on rice farms needs to be calibrated ...
