Honestly, we will see how this goes implementation-wise, but I do like the idea. Using solar panels not just for electricity, but also as sails to help cargo ships reduce emissions, could be an interesting way to minimize their carbon footprint. The key will be getting the tech to a point where it's a net financial benefit as opposed to a cost they absorb for the sake of being green. https://spectrum.ieee.org/energywise/energy/renewables/energysails-harness-wind-sun-clean-up-cargo-ships
