Researchers at the Karlsruhe Institute of Technology in Germany, have created an invisibility cloak that could lead to more efficient solar cells by manipulating a beam of light to concentrate solar rays into more efficient solar energy technology

A cloaking device for ships in the water relies on waves and involves changing the shape of waves so they pass under the boat without causing harm. The idea is that a ship would have the technology to project a new sea floor below and in front of its path. It would change the shape of the wave causing it to safely move under the ship without causing harm. This could save lives and lots of money and be used on near-shore and on-shore sites to protect buildings and property from storm surge

Scientists are developing acoustic and fluid cloaking methods that could defeat radar and sonar sensing.
