As we move away from large power plants with massive rotating turbogenerators, there will be problems with maintaining lock-step grid system frequency stability. Wind turbines have much less ...

For years, B. Ubbo Felderhof has explored the mechanisms fish and microorganisms rely on to propel themselves. He has created mechanical models to support the theory behind the 'swimming' of ...

A new theory of inertia could explain how NASA is generating thrust with a new drive design, and may even show them how to make it more powerful. Share on Facebook (opens in a new window) Share on X ...

About 10 years ago, a little-known aerospace engineer called Roger Shawyer made an extraordinary claim. Take a truncated cone, he said, bounce microwaves back and forth inside it and the result will ...
