Fusion that doesn't need massive reactors and billions of dollars.

Energy abundance through Nuclear Fusion.

Institutional Partners
Stars are not hot enough for fusion, per classical physics.

The Sun’s core is 15 Million kelvin, while fusion competitors on Earth are designing reactors that operate at +150 Million Kelvin. These extreme temperatures and pressures require massive infrastructure and billions of dollars.

Lemma instead enhances a phenomenon that happens naturally in the stars - quantum tunneling.

The sun shines because quantum physics governs the behavior of particles at an atomic scale. While the atoms in the Sun do not have sufficient kinetic energy to overcome the force of electrostatic repulsion, there’s a small, non-zero probability that their wave-like nature lets them "tunnel" through the energy barrier, enabling the nuclei to get close enough for the strong nuclear force to bind them. This low probability event, called ‘quantum tunnelling’, occurs frequently simply due to the sheer number of atoms in the sun. A reactor on Earth can’t house the number of atoms as the sun. However, we can drastically increase the number of interactions and the probability of quantum tunnelling.

Innovation

Interstitial Pseudo Muon Fusion.

A step-change reduction in the cost, size and mass of fusion reactors.

Accelerator Guns

Tapered magnet geometry and REBCO spirals create Pseudo Muons at a low energy cost

Solid Lattice Target

Deuterium ions pre-saturated in a solid lattice target to build up and contain particle density.

Pseudo-muons Bombardment

Pseudo-muons are implanted into the target lattice to compress interatomic spacing.

Energy Excitiation

Lasers, ultrasound, and microwave radiation excited the compressed Deuterium ions within the target lattice.

Voltage Cycling

Increases the wavelength of ions, increasing the cross-section of reactions, and forces interactions, enhancing quantum tunnelling.

Resonance Chamber

Reflects neutrons released back into the target to amplify the rate of D-D fusion.

Applications

Neutron Flux for Medical Isotopes

We’re working on producing a reliable, domestic, low-cost supply of neutron flux for Mo-99 production.

Neutron Flux for Radioactive Waste Treatment

Radioactive nuclear waste stays around for millennia. Our fusion reactors would transmute high-level radioactive waste from nuclear fission into useful products.
