Biofuels may indeed offer a greener alternative to fossil fuels, but they do raise at least one concern – crops grown as biofuel feedstock could take up farmland and use water that would otherwise be used to grow crops for much-needed food. That's why some scientists have looked to seaweed as a feedstock. Kelp is particularly attractive, in that it's abundant and grows extremely quickly, although its fuel yields haven't been particularly impressive. That could be about to change, however, thanks to a newly-developed hydrothermal process.
Joining the ranks of homes built with edible materials, such as the Tourner autour du Ried
, made using corn cobs, and the Mushroom Tiny House
, built with (you guessed it) mushroom-based products, is the Modern Seaweed House. Located on the small island of Læso in Denmark, the house features a simple wooden structure covered with an insulating layer of seaweed.
At last, those agonizing about what to do with all that spare seaweed they have lying around the place can take a leaf (or perhaps frond) out of Nir Meiri's book. The Tel Aviv-based designer's Marine Light amply demonstrates that dried seaweed can make rather a natty lampshade.
