British startup Water-Filled Glass has developed panes of glass filled with water that use sunlight to power a “crazy” energy-saving heating and cooling system.

Water-Filled Glass (WFG) aims to use the patented technology, which it estimates can reduce energy bills by 25 per cent, to make heavily glazed buildings more sustainable.

Other stories in this week’s newsletter include a roundup of architecture projects to look forward to in 2023, Sony’s reveal of its first-ever electric car and an attack on Oscar Niemeyer’s government palaces in the Brasília riot.
