'''SeeGen''' (the '''Sustained Excess Energy Generator''') is a reported low energy nuclear reactions (LENR) reactor system using palladium-coated nickel mesh in a sealed hydrogen atmosphere. A report by Prahlada Ramarao, Shree Varaprasad NS, and collaborators describes long-duration testing of the system at the Center for Energy Research in Bangalore, India, affiliated with Swami Vivekananda Yoga Anusandhana Samsthana (S-VYASA).

The report presents SeeGen as a resistively heated metal-hydrogen system intended to investigate sustained excess thermal power generation. Its claims remain preliminary, with the report identifying the need for higher-precision calorimetry, stronger nuclear diagnostics, and more complete isotopic and gas analysis.

== Reactor design ==

The reported reactor design used a stainless steel cylindrical enclosure, a central axial resistive heater, and internal multilayer nickel mesh. The nickel mesh was coated with palladium using electroplating, spot deposition, or mechanical compaction. Reactors were sealed after hydrogen filling at low initial pressure, reported as about 20-40 Pa at room temperature.

The main comparison arrangement used a cluster of four reactors: three active reactors containing palladium-coated nickel mesh and hydrogen, and one control reactor containing hydrogen without the palladium-coated nickel mesh. The report states that the reactors had identical geometry, heater input, fabrication, and fill pressure. Electrical input was commonly 100 W, with tests also reported over a range from 25 W to 200 W.

== Reported thermal results ==

The report describes more than 500 experimental runs, with approximately 100 said to show reproducible excess heat relative to matched control reactors. In the cluster tests, the active reactors reportedly reached a sustained temperature differential corresponding to about 30 W of excess thermal output at 100 W electrical input, for an estimated coefficient of performance near 1.3.

Thermal behavior was reported to reach steady state after roughly 68 hours. The reported excess thermal power range across runs was about 25-32 W. Some experiments were described as operating continuously for up to three months while maintaining the temperature differential.

== Measurement methods ==

The report lists three calorimetric approaches: air-flow calorimetry, isothermal calorimetry, and surface-temperature-based thermal loss modeling including conduction, convection, and radiation. Instrumentation reportedly included K-type thermocouples, multi-point temperature acquisition, and continuous data logging.

== Replication and analysis ==

The report states that hardware was transported to IIT Guwahati and that excess heat was reportedly reproduced after about one and a half months of setup and testing. It also describes post-experiment gas analysis at the Indian Institute of Science (IISc), Bangalore using quadrupole mass spectrometry. Helium was reportedly detected in two experiments, while no pre-run helium was observed, but the report says quantification was not resolved because of instrument-resolution limits.

Post-run material analysis reportedly indicated changes in nickel, palladium, and copper ratios, occasional copper presence, and nickel isotopic shifts. The report does not establish a definitive reaction pathway.

== Limitations ==

The report identifies several limitations. Helium production was not quantified, no raw calorimetric dataset was published with the summary, no blind third-party calorimetric audit was presented, and no neutron or gamma spectroscopy was reported. The report also notes the absence of detailed uncertainty propagation analysis. Because of these limitations, the reported observations are best treated as preliminary claims requiring independent validation.
