Nothing new under the sun
It always amuses me as a seasoned electric boat historian when on Facebook or a beautifully designed website, a startup ignorantly claims a “world first” for an innovation in electric boating. 1)The first electric passenger boat with a primary battery was tested by Moritz Herman…
Up the creek without a paddle
An article by Charles Mathys Project Overview Using an Arduino Uno computer, the voltage of an 18 volt battery pack is modified to match the 12 volt trolling motors specifications. Using PWM techniques, 6 forward and 3 reverse speeds are programmed to make the trolling…
A Dutch First: Refueling Hydrogen at a Solar Island
Powering ships by hydrogen, refueled at seaworthy floating solar islands? If it is up to SolarDuck and Voyex, this will become a reality for the shipping sector. A prototype of such a solar-island will soon be on display on the Waal near IJzendoorn, a Dutch…

When ammonia becomes toxic
Ingeborg Ann Hjelle Article from University of Oslo Ammonia is very toxic to the brain and new research shows why: the glial cells ability to remove potassium is disturbed. Until now, we have had limited knowledge on the mechanisms underlying ammonia toxicity to the brain. Researchers have…
Natural gas is a much ‘dirtier’ energy source than we thought
In the thick of a Greenland summer of field work in 2015, Benjamin Hmiel and his team drilled into the massive ice sheet’s frozen innards, periodically hauling up a motorcycle-engine-sized chunk of crystalline ice. The ice held part of the answer to a question that had vexed…
Renewables overtook fossil fuels in Europe for first time last year
Europe’s share of renewables in its electricity mix is twice the global average, making the continent a critical hotbed of innovation to better integrate more variable renewables into power grids. Renewables became the dominant source of electricity in Europe’s power grid for the first time last…
Global Ice Melt Matches Worst-Case Climate Scenario, Study Says
The first global ice-loss survey using satellite data showed ice is disappearing faster in Antarctica and Greenland Melting on the ice sheets has accelerated so much over the past three decades that it’s now in line with the worst-case climate warming scenarios outlined by scientists. A total of…
