Tides are more predictable than winds or sunshine. Then, why are not they already widely used as a source of renewable energy? The simple answer is that designing and building an ocean energy array is quite complex. This complexity has […]

One thing is designing an object in a computer, and another, quite different, is producing it as a real 3D object. All other things being equal, in general the more curves the designed object has, the more difficult it is […]

Floating structures are becoming increasingly popular. They are used by several industries, some have been in business for decades, like those dedicated to oil and gas, some are newer, like renewables (wind, wave, tidal), and there are still some other […]

Reducing weight in all kinds of vehicles is currently one of the hot topics for Materials Science and Product Design. This goal is directly related to one of the grand challenges that society is facing, that is, mitigate greenhouse gases […]

Nowadays, the industry is centering their efforts on the development of single aerial robots carrying single objects, such as the widely-known drone of Amazon for delivering packages, which was followed by some national post-office services. However, other approaches go a […]

Trains are one of the least consuming means of transport, and it is mainly due to the metallic wheels and rails: there is almost no energy dissipation due to the rolling contact. Of course, not everything is so great with […]

 
In lay people’s minds, railway lines are composed by rails and wooden sleepers on a bed of stones. These medium-sized stones are called ballast, and it is true that they are the most common material to lay the track […]

Trains have a huge seasonal problem each autumn: leaves. Yes, leaves from the trees. And now they are testing a solution: laser beams! It sounds absurd, but it will all make sense after we get into its science.

Every autumn […]
