Given all the incredible technology developed or improved during the Apollo program, it’s impossible to pick out just one piece of hardware that made humanity’s first crewed landing on another celestial body possible. But if you had to make a list of the top ten most important pieces of gear stacked on top of the […]
If you follow the world of clean energy, you will probably have read all about the so-called hydrogen future and the hydrogen economy. The gas can easily be made from water by electrolysis from green solar electricity, contains a lot of stored energy which is clean to recover, and seems like the solution to many […]
In theory, water and electric current will cause electrolysis and produce oxygen and hydrogen as the water breaks apart. In practice, doing it well can be tricky. [Relic] shows an efficient way to produce an electrolysis cell using a few plastic peanut butter jars and some hardware. The only tricky point is that you need […]
A team at MIT led by [Professor Douglas Hart] has discovered a new, potentially revelatory method for the generation of hydrogen. Using seawater, pure aluminum, and components from coffee grounds, the team was able to generate hydrogen at a not insignificant rate, getting the vast majority of the theoretical yield of hydrogen from the seawater/aluminum […]
Potentially coming to a service station near you. In every comment section, there’s always one. No matter the electric vehicle, no matter how far the technology has come, there’s always one. “Only 500 miles of range? Electric cars are useless! Me, and everyone I know, drives 502 miles every day at a minimum! Having to […]
When we think about hydrogen and flying machines, it’s quite common to imagine Zeppelins, weather balloons and similar uses of hydrogen in lighter-than-air craft to lift stuff of the ground. But with smaller and more efficient fuel cells, hydrogen is gaining its place in the drone field. Project RACHEL is a hydrogen powered drone project […]
There’s something oddly menacing about some vacuum tubes. The glass, the glowing filaments, the strange metal grids and wires suspended within – all those lead to a mysterious sci-fi look and the feeling that strange things are happening in there. Add in a little high voltage and a tube that makes its own hydrogen, and […]
