Direct numerical simulations let researchers improve combustion efficiency and lower pollution in diesel engines. “Cool flames” may sound contradictory, but they could lead to better engine designs ...

Cold fusion, despite probably being impossible, is a good idea. Take a process known to create a meaningful amount of power and remove the harmful byproducts (like explosions), and you've got a winner ...

What makes a diesel engine different to a regular gas engine, and is one better than the other?
