Adding water turns it into tungsten oxide hydrate, and when this is used in electrochromic windows it gives it an extra setting. When switched off, it remains transparent to light and heat – ideal for ...

A smart window that automatically keeps heat in during the winter and lets it out in the summer could be a cost-effective and scalable way to save energy. Windows are one of the least efficient parts ...

A study suggests an approach to speed up the transition of smart glass windows from clear to tinted. Smart windows transition between transparent and tinted states by using small voltages to drive ...
