If rolled out globally, the islands could offset the total global emissions from fossil fuels.
Millions of floating islands that convert atmospheric carbon dioxide to fuel could help prevent our climate from the burning of fossil fuels, scientists have said. These proposed islands would be clustered together to create large-scale facilities that—if enough were built—could eventually offset the total global emissions from fossil fuels.
"Humankind must cease CO2 emissions from fossil fuel burning if dangerous climate change is to be avoided," they wrote."However, liquid carbon-based energy carriers are often without practical alternatives for vital mobility applications. The recycling of atmospheric CO2 into synthetic fuels, using renewable energy, offers an energy concept with no net CO2 emission.
The team says 70 of these artificial islands would make up a single facility that covers an area of around one kilometer squared . Facilities could be placed in areas where wave height reaches less than seven meters, where there is a low probability for hurricanes and the water depth is less than 600 meters, so the islands can be moored properly. Locations for facilities were found across the globe, with the coasts of South America, Australia and Southeast Asia particularly suitable.
