Wave power, also often referred to as tidal power, has been an ‘on’ and ‘off’ topic over the last decade. Many technologies have emerged over the years, many of them have failed (mainly because of underestimating the power of the oceans), and of […]

For example, gasoline has an energy density of about 12.8 kWh/kg (kilowatt-hours per kilogram), which gives, even at just 25% maximum internal combustion engine efficiency, extensive […]

The research was funded by the National Science Foundation and published in the electronic issue of Deep Sea Research Part II: Topical Studies in Oceanography.
