Exists another way to extract energy from oceans which don’t involve waves and tides. The method of oceanic thermal energy conversion (OTEC) is today’s subject.
Exist two voltage supply bands to domestic residences: 100 to 127 V and 200 to 240 V. Differences between these voltage levels in rms are today’s subject.
This is second part of Museo Nacional Aeronautico y del Espacio, are shown the exposition of inner part and an external area.
I was in Santiago, Chile and I visited the Museo Nacional Aeronautico y del Espacio. This museum shows aircraft that were used by Fuerza Aérea de Chile (FACh). This post…
This post’s subject is the operation of underwater turbines. Also are called free flow turbines and remind wind generators.
The biggest aircraft in the world, the Stratolaunch, makes your first flight.
In this post are shown theorems of superposition, Thévenin and Norton. Only DC circuits with resistors are used as examples.
In this post is explained the operation and applications of Gorlov turbine. It is a modification of Darrieus turbine and used in wind and hydroelectric energies.
I received some questions about aerodynamics. In this post I will give an introduction to this physics branch and answer the questions.
Darrieus turbines can be used in wind and hydropower generators. The operation of this type of turbine is the post’s subject.
