Dreaming of stars.

"The indigenously designed and built Prototype Fast Breeder Reactor (PFBR) at Kalpakkam in Tamil Nadu successfully attained its first criticality on 6th April 2026, marking the initiation of a sustained chain reaction." "Once fully operational, India will become only the second country in the world after Russia to operate a commercial fast breeder reactor." pib.gov.in. "During the same time India's first PFBR achieved criticality, Bengaluru-based startup Pranos raised $6.8 million in seed funding to build India's first commercial fusion reactor prototype." "Fusion-based reactor technology is gaining traction with a couple of Indian-startups looking at power generation by 2035, while thorium-based rectors are a few decades away." "India is already contributing Rs 7.45 billion in 2026-27 for a global fusion project, the International Thermonuclear Experimental Reactor (ITER), a multi-country endeavour located in France." BT. India's top companies Reliance and Adani are interested. The Indian Space Research Organisation (ISRO)  spent "$74 million on the Mars orbiter Mangalyaan and $75 million on...historic Chandrayaan-3 - less than the $100m spent on the sci-fi thriller Gravity." Nasa's Maven orbiter cost $582 million and Russia's Luna-25, which crashed on the moon's surface, cost $133 million. BBC. Although, India has a track record of achieving great scientific success on a shoestring budget, $6.8 million is really loose change for fusion research. China Fusion Energy and Neo Fusion of China have budgets over $2 billion, while Commonwealth Fusion Systems and Helion Energy of the US have budgets of nearly $3 billion and over $1 billion respectively. FEB. Tokamak technology has been around since !960. The Tokamak Fusion Test Reactor (TFTR) was built at Princeton Plasma Physics Laboratory in 1980 and entered service in 1982 but it could never achieve break-even, which means it used more power than it produced. It was dismantled in 2002. wikipedia. In December 2022, "an experiment carried out at the Lawrence Livermore National Laboratory (LLNL) in California had for the first time managed to produce more energy than it than it consumed via nuclear fusion," but "The experiment in California was carried out under special conditions that cannot be replicated anywhere else in the world and produce modest results in terms of the amount of energy generated," wrote Marcos Pivetta. Perhaps, the biggest hurdle will be electricity. ICRA estimates electricity demand to grow by 5-5.5% on FY 2026 and by a compound annual growth rate of 6-6.5% over the next five years. ET. It is not sure whether this takes into account that "India's data center capacity is expected to surge nearly six-fold from about 1.5 GW in 2025 to 8-10 GW by 2030, while electricity consumption from the sector is expected to rise sharply from 10-15 terawatt hours (TWh) in 22024 to 40-45 TWh by 2030." FE. It's good to dream of producing fusion energy of stars in India. Others have tried and failed. At least it's cheap at $6.8 million.
