Solar-powered clothing could be the next big trend for environmental enthusiasts. Researchers at North Carolina State University have designed a process called digital textile printing that makes it possible for solar panels to be fitted into jackets and ties.

However, the researchers did find problems with the neck tie: the solar panels make it extremely difficult to tie knots. They propose using a clip-on tie to remedy this problem.

The research team’s tie design contains a cell-phone pocket and 3.6V plug-in. And no, the solar clothing doesn’t create any dangerous electric shocks.
