🔋 Biodegradable batteries that decompose after a month
Toxic E-waste is a rapidly growing problem, but fortunately, scientists from Nanyang Technological University in Singapore have come up with a partial solution to the toxic e-waste of batteries. A biodegradable battery that can be buried in soil once it no longer...
🚮 Crows to clean up Swedish city – and they’ll do it for peanuts
In 2020 a man called Hans Forsberg shared a video of his clever invention that dispenses peanuts when bottle caps are inserted. He then "trained" local birds to operate the device, and before long, a wealth of avians were routinely cleaning the surrounding...
☀ Sharper simulations mean more efficient solar panels
To get as efficient solar panels as possible, researchers run elaborate simulations to test different materials, structures, layer thickness, and more to see which combination gives the best results. The simulations are complex, require a lot of computer power, and...
🔋 “Sea battery” provides energy even when it is not windy
A shortcoming of wind power is that it doesn't generate any electricity if it is not blowing. The solution is to store enough energy when wind power produces more electricity than needed. The Dutch company Ocean Grazer has now developed a new "offshore...
