Thames water in London UK is hoping to use excess heat from sewage treatment plants to provide the warmth needed for 2000 homes in Kingston-upon-Thames.
What normally happens, is that once the water has been fully treated, it is returned to the river. The problem with this, is that the water is at a higher temperature than the river, and this is not good for its ecosystem.
A new system can transform thousands of hills in the UK into large batteries. A team of engineers have developed a system which would allow Hydropower to store and release power within gently sloping hills and without the huge dams currently needed.
The idea of these small hydropower systems, is that we could build many of these tiny dams for far less than just a few large ones. More importantly, it would come with far less negative issues to those that come with historic large dams (for instance the proposed dam which threatens the future of 8th great ape species the Tapulani Orangutan).
At the beginning of January an new agreement was signed by 50 countries who pledged to protect 30% of the earths land and oceans. The intention of this agreement is to stem the flow of extinctions that human activity has been causing for the last few centuries.
The hope is that this agreement can form the basis of a larger agreement at the UN, building on the early commitments from nations such as Nigeria Pakistan Costa Rica Canada and many more.
Over the last few years it has become increasingly clear that conservationists approach to fossil fuel companies were not working.
The problem is that there is a great deal of money to be made from fossil fuels. Companies like tesla hint at a world where this ceases to be the case, and the speed that the electric car market is growing, is incredibly fast. Indeed many people have commented on the fact that the growth curve of electric cars is clearly following the curve of many other disruptions from computers to mobile phones.
Palm oil is a wonder material. Being used in a vast range of different products, it is almost impossible to avoid it in the west. Why should we try? because it has been the cause of much of the rainforest destruction on Sumatra, Borneo and lately even in the last great rainforests of west Africa.
I have written in the past, about a discovery made on a Japanese dump back in 2016 of a plastic eating enzyme. By working in the lab, scientists have been able to speed this process up 6 times, such that full recycling is thought to be possible of plastics within 2 years.
