MIT Extracts Power from Temperature Fluctuations

Posted on by

As a civilization, we are proficient with the “boil water, make steam” method of turning various heat sources into power we feed our infrastructure. Away from that, we can use solar panels. But what if direct sunlight is not available either? A team at MIT demonstrated how to extract power from daily temperature swings.

Running on temperature difference between day and night is arguably a very indirect form of solar energy. It could work in shaded areas where solar panels would not. But lacking a time machine, or an equally improbable portal to the other side of the planet, how …read more

Coke Can Fueled Power Generator

[Experimental Fun] shows us how you can create a cola power generator that runs on nothing more than cans of cola including the container and a little bit of sodium hydroxide to speed the reaction up.

This might sound a bit crazy, but it seems you can power an engine on little more than your favorite fizzy drink and the cut-up remains of an aluminum can. What happens is that aluminum and water create a chemical reaction when mixed together, which gives off hydrogen. Normally this reaction is very slow and would take years to make any noticeable marking on …read more
