Ok, now that I have your attention...:rolleyes:

From eyesore to asset: How a smelly seaweed could fuel cars

An interesting bit of local ingenuity.

When large swathes of invasive seaweed started washing up on Caribbean beaches in 2011, local residents were perplexed.

Soon, mounds of unsightly sargassum – carried by currents from the Sargasso Sea and linked to climate change – were carpeting the region's prized coastlines, repelling holidaymakers with the pungent stench emitted as it rots.

Precisely how to tackle it was a dilemma of unprecedented proportions for the tiny tourism-reliant islands with limited resources...

Now, a pioneering group of Caribbean scientists and environmentalists hope to turn the tide on the problem by transforming the troublesome algae into a lucrative biofuel.

They recently launched one of the world's first vehicles powered by bio-compressed natural gas. The innovative fuel source created at the University of the West Indies (UWI) in Barbados also uses wastewater from local rum distilleries, and dung from the island's indigenous blackbelly sheep which provides the vital anaerobic bacteria.

The team says any car can be converted to run on the gas via a simple and affordable four-hour installation process, using an easily available kit, at a total cost of around $2,500 (£1,940)...

Researchers had initially looked into using sugarcane to reduce reliance on costly, imported fossil fuels and help steer the Caribbean towards its ultimate target of zero emissions.

However, despite Barbados being one of few islands still producing sugarcane, the quantity was deemed insufficient for the team's ambitious goals, explains the project's founder Dr Legena Henry.

"Sargassum ...is something "we will never run out of"....

Double-edged sword. The Sargasso Sea is a major breeding ground/nursery for many species of marine life. Now some company will insist on collecting every single weed of it and destroy all that. They won't be satisfied with collecting what washes ashore.
 
Sarge makes a good point.
A 5 gal. bucket at the beach has a lot of uses but I enjoyed most the look of amazement on a child's face when they saw the amount of tiny shrimp, fish, snails, crabs and sea horse fall out as I shook a small handful taken from the water.
Hard to believe that such a vast resource could be depleted but history has shown otherwise. Still a good idea that may have some practical application.
 
Everything in nature has a purpose. Even sargassum. It would be better to collect the vast amount of plastic waste floating in the world's oceans and convert it into something useful.

The sargassum undoubtably has a purpose out in the open ocean / Sargassum Sea, supporting marine life, maybe regulating water temperatures, etc., but in this case, the vast amounts coming ashore in the last dozen years is a new phenomenon. Does it serve a useful purpose when rotting on the shore? It would seem not; it's done its thing out in the ocean and is now "stinking up the front yard," unpleasant for the locals and bad for tourism. So I'd say it's good that the local scientists are developing a new use for it, even if it only ends up running vehicles in that geographical area.

SMSgt and soFlaNative's warnings are valid, though - let Big Business get their greedy teeth into it and there could be trouble.

As to cleaning up the plastics in the world's oceans (not to mention preventing it from getting there in the first place) amen to that, but that's beyond the scope or capabilities of the Caribbean islanders.
