Gears are one of the oldest and most fundamental inventions in the history of engineering. Over the centuries, these mechanisms have evolved from simple wooden devices to complex systems for transmitting force and motion. From the most rudimentary applications to the most advanced, gears have played a crucial role in the development of modern technology.

In this article, we will break down in detail the theory of gears, their components, applications, and the different forces involved in their operation. From their geometric properties to the calculations necessary for their design, we will cover the most relevant aspects that allow gears to be used in multiple industries.

The Stellarator is a type of nuclear fusion reactor that uses extremely complex magnetic fields to confine plasma and facilitate fusion reactions. This concept, often less known than the tokamak, has been the protagonist of recent advances that consolidate it as a viable alternative for fusion energy. The entire fusion process is based on the same reactions that occur in stars, hence its name: Stellarator, or “star generator.”

The challenge of containing and controlling a fusion reaction for sufficient time is colossal. Achieving efficient plasma confinement to maintain the necessary temperatures and pressures has been the main barrier, but thanks to developments in computing and magnetic field design, Stellarators have become a promising option in the race toward clean and almost infinite energy.

ITER is one of the most ambitious projects in the history of science and technology, aiming to recreate on Earth the nuclear fusion process that occurs in stars like the Sun. This experiment seeks to demonstrate that it is possible to obtain fusion energy efficiently and sustainably.

The ITER project, whose name refers to the Latin term meaning “path,” brings together the world’s leading powers and is being constructed in Cadarache, in the south of France. The goal is to prove that this type of energy can be viable on a commercial scale, which would represent a major advance toward a future with clean and practically unlimited energy.

Quantum Kinetics Corporation (QKC) has achieved an unprecedented breakthrough in the field of energy through nuclear fusion. In a series of peer-reviewed experiments, the Seattle-based company managed to maintain a plasma fusion temperature of 200 million degrees Celsius for a full 24 hours, vastly surpassing the previous record set by Korea’s KSTAR reactor, which had reached 105 million degrees for only 48 seconds.

This is a historic achievement for the field of energy via nuclear fusion, as QKC has not only broken records but also succeeded in breaking down radioactive isotopes like Uranium-234, -235, and -238—something that was considered impossible until recently. The company has dubbed this process Safe Nuclear Systems™.

Japan has achieved a milestone in space exploration by launching the first satellite made of wood into space. Named LignoSat, this innovative project is the result of a collaboration between Kyoto University and Sumitomo Forestry, aiming to demonstrate that this renewable material can withstand the extreme conditions of space.

LignoSat, whose name derives from the Latin lignum meaning wood, is not just a scientific advancement but an important step toward the future of sustainability in the space industry. The satellite was launched aboard a SpaceX mission destined for the International Space Station (ISS) and is later expected to orbit the Earth at about 400 kilometers altitude.
