Does all it require to create fusion energy is to heat something up to 8000 C? Is that in principle all that it requires? Does it require any other fundamental tricks?
One won't get much of a plasma at 8000 K. It should be more like 8 keV * 11605 K/eV ~ 93 million K.bobsmith76 said:Does all it require to create fusion energy is to heat something up to 8000 C? Is that in principle all that it requires? Does it require any other fundamental tricks?

It's not as easy as one thing, particularly the time of multiple laser beams as well as repetitively hitting the same spot at the same time.debra said:It should be easy to create the necessary fusion temperature because there is no theoretical limit (AFIK) to how much laser energy can be put into a small space.
So it is only a matter of concentrating enough laser beams onto one spot.
Cannot understand our delay in this one. It should be possible even with a small laser in a thin enough beam.
There is no ingenious easy answer, but it is a matter of overcoming hurdles with a clever or ingenious solution.debra said:Oh, so it looks like practical solution are difficult. Do you think there will be an ingenious easy answer or is it a matter of continuing overcoming hurdles?
The main technical obstacles to achieving fusion energy for civilian purposes include the need to create and sustain a plasma at extremely high temperatures and pressures, the challenge of confining the plasma for long enough periods of time, and the development of materials that can withstand the intense conditions inside a fusion reactor.
Fusion energy has been difficult to achieve because it requires extremely high temperatures and pressures that are difficult to create and sustain, as well as long periods of confinement. Additionally, the technology and materials required for fusion reactors are still in the early stages of development and are not yet fully optimized.
Scientists are working on various strategies to overcome these obstacles, including developing new and improved plasma confinement techniques, optimizing the design and materials of fusion reactors, and exploring new fusion fuel sources. They are also conducting extensive research and experimentation to better understand the complex physics of fusion reactions.
It is difficult to predict an exact timeline for achieving fusion energy for civilian purposes, as it is a complex and ongoing research and development process. However, many scientists and experts estimate that it could still be several decades before fusion energy becomes a viable source of energy for widespread use.
If fusion energy can be successfully harnessed for civilian purposes, it could provide a virtually limitless source of clean and sustainable energy. It would also significantly reduce dependence on fossil fuels and help mitigate the effects of climate change. Additionally, fusion reactions produce minimal waste and do not emit greenhouse gases, making it a much more environmentally-friendly option compared to other forms of energy.
