It might power your car
In 2012 American scientists figured out a way to turn the sugars from seaweed into biofuel. Various countries are exploring the best way to do this on a larger scale, including the Scottish Association of Marine Science who are working with Ireland and Norway (big seaweed producers) to find a breakthrough that would lead it being a commercially viable fuel.

It will power your garden
With 10 times the minerals of land based plants, seaweed is as good for your garden as it is for you. Collect washed up varieties and either add directly onto the beds or compost it, as it breaks down it will help convert micro-organisms into versions your plants can use as fuel. The seaweed will help the health of the roots, improve chlorophyll production and just generally help your plants to thrive.

It should go in your bath
The Japanese have sworn by seaweed to increase circulation and get rid of cellulite for centuries. It’s thought to reduce the signs of ageing, soften skin and aid good sleep. On the west coast of Ireland, there are public seaweed saltwater baths which have been locally popular for over a century. If you can’t get to the Connemara Seaweed Baths, the Cornish Seaweed Company has bath bags you can use at home.
