Volcano island spewing forth rocks with platic embedded in them

The Brazilian island, Trindade, has produced a new kind of rock - a ""plastiglomerates" because they are made of a mixture of sedimentary granules and other debris held together by plastic. Through studying the plastic, they've identified that a lot of it comes from fishing nets that wash up on beaches.

Data center warming public children's pool saves the pool operators an estimated $24k annually

The high-performance cluster server is submerged in a pool of mineral oil - a very effective way to cool systems - and a heat-exchanger transfers the heat into the children's pool! The pool still has a boiler in case it gets too low, but overall it will save a lot of money.

The company behind the install is trying to create more installations like this to recover waste heat - this pool installation claims to recover 97%(!) of its waste heat - rather than just venting it into the air and causing more climate disruption.
