Producing silicon results in large carbon dioxide emissions, but recirculating it can remove contaminants more efficiently.
An old building at Tullinløkka in Oslo has set a new standard for reuse, consisting of components from other buildings – like concrete floor dividers from a government building. Building stock in Norway accounts for half of society’s total environmental impact. Thinking in new ways and reusing building components offers multiple gains.
Large cost cuts are achievable for both floating and bottom-fixed wind farms in the future. If we do this correctly, floating wind turbines will be able to compete with bottom-fixed wind turbines by 2030.
France covered up the consequences of their nuclear tests in the Pacific. As many as 110 000 people may have been exposed to radioactive fallout above the assumed safe levels.
Relatively simple adaptation could make the cargo ships of the future completely green. The technology is based on the chemical compound ammonia, some extensive number crunching and one or two engine modifications.
