Lucid Dream Communication

REMspace has successfully sent messages between two people while dreaming. Their system allowed a chat word to be injected into a lucid dream of a person, who responded with another word in their dream. Their response word was recorded bythe system and injected into a lucid dream of a second person, who confirmed the response word when they woke up!

Harnessing Heat From Underground Car Parks

Scientists in Germany and Switzerland measured the ambient air temperature of underground car parks, and the temperature of the groundwater beneath them, and found that those car parks generate a lot of waste heat, which heats the groundwater and impacts on biodiversity and water quality. Extrapolating their findings, the scientists estimate that all 5040 underground car parks in Berlin could heat 14,660 average German homes by harnessing the waste heat using heat pumps.
