Sustainable mobility has made significant progress, and we’re not just referring to Spain’s first service station for this fuel. Did you know what has been uncovered? It’s the proton engine that Einstein envisioned decades ago and has now been realized for the first time. The most astonishing part? This engine challenges the established laws of physics and the universe, and it holds the potential to transform the decarbonization of transportation.
Einstein envisioned a nuclear fusion engine: it has just been created
Nuclear fusion has long been an ambitious but elusive goal for scientists. This process involves combining atomic nuclei to release energy, similar to what takes place in the Sun and other stars. In fact, it is akin to the plasma engine we discussed two weeks ago.
In contrast to nuclear fission used in today’s nuclear power plants—which we criticize for being neither ecological nor renewable—fusion presents the promise of a nearly limitless and clean energy source.
As early as 1929, Albert Einstein theorized about the potential for a “proton engine” based on nuclear fusion that could propel spacecraft at speeds approaching the speed of light. The concept involved using the high temperatures of fusion to eject a stream of protons and create thrust.
Technological advancements: a relentless evolution
Previous efforts to develop a nuclear fusion engine were hindered by technological constraints. However, significant advancements in various fields over the past few decades now make it possible to attempt the creation of this groundbreaking engine.
One of the critical advancements has been in the development of new materials that can endure the extraordinary high temperatures within a nuclear fusion reactor. Special alloys and advanced ceramics have been created that can contain the superheated plasma required for fusion.
Another significant factor is the enhanced understanding of plasma physics and nuclear fusion. Scientists now possess much more accurate computer models to simulate and regulate fusion reactions. This advancement grants them a better ability to stabilize and maintain the necessary reactions.
Additionally, new magnetic confinement techniques and electric fields have been established to contain the hot plasma. This prevents the plasma from making contact with the reactor walls, which would cool it and halt the reaction. New superconducting magnets play a crucial role in this process.
The first proton engine, ready to decarbonize transportation (even on Earth)
RocketStar is a startup founded in 2021, focused on developing a nuclear fusion propulsion engine. Its objective is to create a revolutionary rocket engine that employs the fusion of hydrogen nuclei to produce extremely high specific impulse.
RocketStar’s design utilizes the fusion of protons (hydrogen nuclei) within a funnel-shaped magnetic field. Protons are introduced at the wide end of the funnel and then compressed as they move toward the narrow end, achieving extremely high temperatures and densities.
Fusion generates substantial amounts of energy that are transformed into a high-speed outward plasma jet. This produces thrust for the rocket without the requirement of chemical propellants. The advantage is that fusion fuel (hydrogen) is nearly inexhaustible and could be utilized in vehicles for the long term.
As you can see, this proton engine demonstrates that when it comes to achieving sustainable transportation, physics and mobility can indeed work together. They have also managed to employ this trick to double the range of electric cars, a development that is currently exciting manufacturers for one simple reason: it seems too good to be true, but thousands of drivers are already discovering how effective it is.
Sustainable Mobility Revolutionized: The Proton Engine
Sustainable mobility has taken a monumental leap, and we are not talking about the first service station for this fuel in Spain. Did you know what they have discovered? It is the proton engine that Einstein predicted decades ago and that, for the first time, has been realized. The most surprising thing? This engine defies the laws of physics and the universe, and promises to revolutionize the decarbonization of transport.
Einstein Predicted a Nuclear Fusion Engine: Now It Has Just Been Created
Nuclear fusion has long been a sought-after but elusive goal for science. It involves joining atomic nuclei together to release energy, the same process that occurs in the Sun and other stars. In fact, it is a similar process to the one we saw two weeks ago with the plasma engine.
Unlike nuclear fission used in current nuclear power plants – which we are very critical of as it is neither an ecological nor renewable option – fusion offers the promise of a virtually inexhaustible and clean source of energy.
As early as 1929, Albert Einstein had theorized about the possibility of creating a “proton engine” based on nuclear fusion, which could propel spacecraft at speeds close to the speed of light. The idea was to use the high temperatures of fusion to expel a jet of protons and generate thrust.
Technology Has Advanced Since Then: A Tireless Evolution
Previous attempts to create a nuclear fusion engine failed due to technological limitations. However, in recent decades there have been major advances in several areas that are now making it possible to try to build this revolutionary engine.
Materials for High Temperatures
One of the major advances has been in new materials capable of withstanding the incredibly high temperatures inside a nuclear fusion reactor. Special alloys and advanced ceramics have been developed that can contain the super-hot plasma needed for fusion.
Advancements in Plasma Physics
Another key factor is progress in understanding the physics of plasmas and nuclear fusion. Scientists now have much more accurate computer models to simulate and control fusion reactions. This gives them greater ability to stabilize and sustain the necessary reactions.
Magnetic Confinement Techniques
In addition, new magnetic confinement techniques and electric fields have been developed to contain the hot plasma. This prevents the plasma from touching the reactor walls, which would cool and stop the reaction. New superconducting magnets are key to this.
The First Proton Engine, Ready to Decarbonize Transport (Also on Earth)
RocketStar is a startup founded in 2021 that is developing a nuclear fusion propulsion engine. Its goal is to create a revolutionary rocket engine that uses the fusion of hydrogen nuclei to generate extremely high specific impulse.
How the Proton Engine Works
RocketStar’s design is based on the fusion of protons (hydrogen nuclei) using a funnel-shaped magnetic field. Protons are injected into the wide end of the funnel and then compressed as they approach the narrow end, reaching extremely high temperatures and densities.
Fusion releases large amounts of energy that is converted into a high-speed outward plasma jet. This provides the rocket with thrust without the need for chemical propellants. The advantage is that fusion fuel (hydrogen) is virtually inexhaustible and could be used in vehicles in the long term.
Benefits of the Proton Engine
- Clean Energy Source: The proton engine harnesses nuclear fusion, a process that emits no greenhouse gases.
- Inexhaustible Fuel: Hydrogen, the fuel for fusion, is abundant and virtually unlimited.
- High Efficiency: Fusion provides a high specific impulse, offering superior performance compared to traditional propulsion systems.
- Reduced Dependence on Fossil Fuels: With the ability to decarbonize transport on Earth, this technology could diminish our reliance on fossil fuels.
Practical Applications
