What is the estimated cost of nuclear fusion research since its inception?

In summary, the current dollar amount spent on nuclear fusion research worldwide is estimated to be at least $7 billion annually. Since its Rutherfordian inception, approximately $100 billion has been spent, including expenses for magnetic and laser fusion. The ITER project has received $17 billion, NIF $4.2 billion, JET $500 million, and Tri Alpha $500 million, totaling over $22 billion. However, this figure may not be accurate due to the inclusion of DOE grants, which have been around $1 billion per year for the last 10+ years. Additionally, there are significant fusion programs in Japan, China, Korea, and Russia that have been ongoing for the past 30 years. Overall, the estimated amount spent

Hey guys,

Do you have ideas on the current dollar amount spent on nuclear fusion research since it's Rutherfordian inception?

ITER $17,000,000,000, NIF $4,200,000,000, JET $500,000,000, and Tri Alpha $500,000,000 are over $22 billion alone. Your figure may not be too far off, especially when considering DOE grants (part of which goes to ITER and NIF?) seem to have been $1,000,000,000+/year for the last 10+ years as well.

~$32,000,000,000 so far.

My $100 billion is in current dollars (as you requested), not as-spent dollars.
For example, JET expenses were far above $1 billion in current dollars (not 500 million).

Don't forget the huge fusion programs in Japan, China, Korea and Russia for the past 30 years.

Worldwide expenditures on fusion are currently at least $7 billion annually.
 

1. What is the estimated cost of developing fusion technology?

The estimated cost of developing fusion technology varies depending on the specific approach and project. Generally, it can range from tens of millions to billions of dollars. For example, the International Thermonuclear Experimental Reactor (ITER) project, which aims to demonstrate the feasibility of fusion energy, has an estimated cost of over $20 billion.

2. How does the cost of fusion technology compare to other energy sources?

Currently, fusion technology is more expensive than traditional energy sources, such as fossil fuels and nuclear power. However, as research and development continue, the cost of fusion is expected to decrease and become more competitive with other sources of energy.

3. What factors contribute to the high cost of fusion technology?

The high cost of fusion technology is primarily due to the complex and challenging nature of the research and development process. This includes the need for advanced materials, high-tech equipment, and highly skilled scientists and engineers. Additionally, the long timelines for developing and testing fusion technology also contribute to the cost.

4. Are there any potential benefits that could offset the cost of fusion technology?

If successfully developed, fusion technology has the potential to provide a virtually limitless, clean, and safe source of energy. This could greatly reduce our dependence on fossil fuels and mitigate the impacts of climate change. It could also create new industries and job opportunities in the energy sector.

5. How can we make fusion technology more cost-effective?

To make fusion technology more cost-effective, continued research and development efforts are necessary. This includes finding ways to improve the efficiency of fusion reactions and reducing the costs of materials and equipment. Collaboration between governments, research institutions, and private companies can also help to share resources and expertise and drive down costs.
