Emissions-free energy system saves heat from the summer sun for winter
- benj111 8y agoI'm confused, does this work by sunlight or heat? "has the unique property that when it is hit by sunlight, it is transformed into an energy-rich isomer" And "The solar thermal collector is a ...." Also what is the energy density? I assume the fact it isn't mentioned means that its pretty poor. Does seem interesting though. Edit: I'll answer my own questions: They're getting referred to as photoswitches in the references, so I guess it's sunlight And one reference quotes 155wh/kg, which seems not great.
