The Case for Nuclear Cargo Ships

Cars That Think

“At the same time, it’s becoming apparent that alternative-fuel solutions we’re looking at have big drawbacks, and that producing these fuels will take a lot of green power that will be needed to replace coal and gas on shore. The feasibility study with Fincantieri will guide how the two companies develop the technology for marine use.
