What happens when you apply the earliest SE Cell model to a real home? This page works through that question for a 2,000 square foot Florida house. The answer exposed a gap: at 10% electrical efficiency, the cell is a powerful thermal device but falls short on electricity. That gap became one of the central design problems the later research set out to solve.

What the Thermal Output Can Do
At ~1,890W continuous thermal, the earliest model's strength is heat-driven applications:

Absorption cooling: ~1,300W cooling capacity (COP 0.7 — meaning 0.7 watts of cooling per watt of heat input) — covers roughly half a Florida home's AC load

Water heater: Continuous thermal keeps the tank warm without electrical draw

Pool heating: Year-round, no additional cost

Lighting: Scintillator light delivered through fiber optics — no electrical conversion

Still on the grid: Cooking, electronics, remaining AC load, motors/pumps. The earliest model supplements the grid — it does not replace it.
What This Model Revealed
The earliest model is 90% thermal, 10% electrical. Applying it to a real home exposed the design priorities for future work:

1. Electrical conversion efficiency must improve significantly — 10% is not enough for grid independence.

2. Using heat directly (for cooling, hot water) is more efficient than converting it to electricity first. This principle held.

3. The thermal output alone covers a large share of a Florida home's energy costs — even before electrical improvements.

This analysis guided the later research toward direct conversion of each energy band without thermal as an intermediate step.
Design Principles at Work
1. Differentiate: Each energy band gets its own conversion pathway — beta, gamma, heat, and light are handled separately.

2. Filter by layer: Gamma waves are transformed inside the cell. Only safe forms of energy reach the surface.

3. Don't convert what's already useful: Heat stays heat for cooling and hot water. Light stays light through fiber optics. Only what must be electricity becomes electricity.
Florida-Specific Notes
Cooling is the biggest cost: Average FL home spends $180–250/mo on cooling. Even partial absorption cooling from ~1,300W thermal makes a significant dent.

Hurricane resilience: The SE Cell runs continuously regardless of grid status. No fuel delivery required.

All-electric homes: Many FL homes have no gas service. The SE Cell provides thermal energy that these homes currently get only from electricity.
Unit Size
The scintillator crystal and shielding make up most of the unit's volume. At 120g cobalt-60, the estimated size is a large chest freezer. Fits in a utility closet, garage, or outdoor pad.
"In this model, the SE Cell is a thermal device that supplements a home's energy — not a grid replacement. The 10% electrical efficiency of the earliest model cannot power a Florida home alone. But 1,890 watts of continuous heat can cool, heat water, and warm a pool — replacing a significant share of utility costs. The gap between what this model delivers and what a home needs is what drove the research toward improving direct conversion of every energy band."
Source: ~120g cobalt-60 at 17.5 W/g = ~2,100W total from decay. At earliest-model efficiency: ~210W electrical (10%) + ~1,890W thermal (90%) + scintillation light via fiber. Daily electrical production: ~5 kWh. Typical FL home demand: 9–13 kWh after removing heat-driven loads from the electrical budget.

Absorption cooling: Proven technology (ammonia-water or LiBr-water cycle). Runs on thermal input — no compressor, no refrigerant phase-out concerns. Same principle as RV propane refrigerators, scaled up. At COP 0.7, ~1,890W thermal input produces ~1,300W of cooling capacity — roughly half a typical Florida home's cooling load.

Fiber optic lighting: Scintillator output at 415nm (blue-violet) transmitted through fiber bundles. Diffusers at room endpoints produce ambient light. No electrical conversion, no wiring for light circuits, no bulb replacement.

Fuel lifecycle: Cobalt-60 half-life 5.27 years — decays to stable nickel-60. Replace capsule, keep the cell and all converter layers.
