Bridge rectifiers and a supercapacitor help electrochemical system manage intermittent nature of wave energy

Scientists have achieved a first in harvesting energy from water waves to make a carbon-based liquid fuel. By generating static electricity from the undulating motion, they are able to convert carbon dioxide into the hydrogen-carrier formic acid.
