Call me a nerd, but this is totally cool on so many levels: http://www.nytimes.com/2016/07/19/science/green-chemistry-mechanochemistry.html

The technique, based on so-called mechanochemistry, or chemistry driven by mechanical force, is radically different from the traditional way of dissolving, heating and stirring chemicals in a solution. Removing solvents could help make many chemical processes used by industry more environmentally friendly.
Many commonly used solvents, like chloroform, acetone and hexane, are harmful and volatile, posing risks to people who inhale them as well as the environment. Solvents also make up the vast majority of chemical waste, and consume most of the energy used in a chemical reaction.But because solvents have been the norm for centuries, many chemists tend to doubt the viability of mechanochemistry. “We learn that solution is just the way to go,” Dr. Mack said, “and never think about alternatives.”
The green chemistry movement has motivated some chemists to ditch the old solution methods in favor of mechanochemistry.

That is cool. I didn't even know it was possible!
