1. Background
In 2014–2024, British inventor Malcolm Bendall has publicly demonstrated a passive after-treatment device — the “Thunderstorm Generator” (TSG) — that is claimed to (a) reduce regulated exhaust pollutants in internal-combustion engines, (b) increase engine power output, and (c) induce persistent material changes (“transmutation”) in the device’s inner stainless-steel components.
The Martin Fleischmann Memorial Project (MFMP), led by Bob Greenyer, has independently examined Bendall hardware and published the hypothesis that the TSG functions as an ambient-temperature realization of Ken Shoulders’ Electrum Validum (EV) phenomenon — bunched-electron clusters documented in vacuum-chamber experiments since the 1970s. Greenyer reports persistent yellow surface features on a TSG inner sphere whose elemental composition, by SEM/EDS, deviates from the original SS-304 substrate. These observations have not been independently replicated under controlled conditions.
The cosmological framework in which Bendall presents the device — the “Plasmoid Unification Model” (PUM) — is a mathematically self-consistent number system and is not a subject of this proposal. We treat the device as engineering and evaluate it on engineering terms.
2. Specific Aims
Aim 1 — Combustion-cycle calorimetry under controlled load
Determine whether a TSG-equipped engine produces measurably different power output, fuel consumption, and net thermal balance relative to an identical unmodified engine, at five operating points spanning idle to rated load.
Aim 2 — Multi-modal exhaust spectroscopy
Quantify the steady-state and transient composition of the engine exhaust, before and after the TSG, using simultaneous five-gas analysis (O₂/CO/CO₂/NOₓ/HC), FTIR, and quadrupole mass spectrometry. Specifically test for (a) NIST-traceable agreement between the three methods, (b) evidence of molecular species not predicted by combustion thermochemistry, (c) anomalous isotope ratios.
Aim 3 — Time-resolved inner-sphere elemental analysis
Construct a TSG to Bendall’s published parts-list. Operate it for a defined duty cycle of 100 ± 5 hours under aim-1 calorimetric conditions. At time 0, 25, 50, and 100 hours, remove the inner two-inch sphere, perform SEM/EDS at five pre-specified locations, and compare to baseline scans. Use proper control samples (an unused SS-304 hemisphere from the same supplier batch, exposed to the same shop atmosphere). Test specifically for the “yellow features” Greenyer reports.
Aim 4 — Magnetometric and radiometric monitoring
Continuously monitor magnetic-field perturbations (16-channel Bartington Mag-13 fluxgate array) and ionizing-radiation flux (gamma + neutron-bubble dosimetry) during operation. Test whether anomalous signals correlate with engine load or duty-cycle phase.
Aim 5 — Replication trial
Build a second, geometrically identical TSG using a different supplier batch. Run aims 1–4 in parallel. Test whether observed effects replicate under same protocol.
3. Approach
3.1 Test article construction
The TSG will be built to Bendall’s published TGMaterialsList.pdf:
- Inner sphere: 2” OD × 0.125” wall (11 Ga.) SS-304 hemispheres × 2, TIG-welded, joint annealed and Argon-quenched per Vajra patent P76426GB protocol
- Middle sphere: 3” OD × 0.125” wall SS-304, TIG-welded
- Outer sphere: 4” OD × 0.125” wall SS-304, TIG-welded
- Tubing: 1.125” OD × 0.065” wall and 0.625” OD × 0.065” wall SS-304 welded round tube
- Bubbler chamber: borosilicate glass, distilled deionized water at standard fill
- UV lamp: 254 nm low-pressure mercury, 15 W, with magnetic ballast
- Compression fittings: SS-316 Swagelok-style throughout
- Total construction cost: approx. $700 USD per device
Two devices will be built (test + replication), differing only by component supplier batch. All raw-material lot numbers will be archived.
3.2 Host engine
Predator 7 kW (212 cc) single-cylinder gasoline-powered portable generator. Selected because:
- Bendall used a similar 380 cc Honda-clone in his 2023 Teslatech demonstration
- Carburetted (vs. EFI) — matches Bendall’s preferred-embodiment description
- Common platform; replaceable; cost ≤ $400
The generator will be mounted on a calibrated dynamometer for power output measurement under load. Two units will be procured (test + control) from the same purchase order; one will run with TSG installed, the other unmodified, for direct comparison.
3.3 Calorimetry (Aim 1)
Five operating points: idle (no load), 1 kW, 2 kW, 4 kW, 7 kW (rated).
For each:
- 30-min stabilization, 60-min measurement, 30-min recovery
- Fuel consumption by mass (Mettler precision scale)
- Coolant inlet/outlet ΔT × flow rate (heat into coolant)
- Exhaust temperature at TSG inlet and outlet (thermocouple cluster)
- Ambient air temperature, pressure, humidity (closed test cell)
- Net electrical output at the dynamometer
Net thermal balance:
Q_fuel = m_fuel × LHV_gasoline (~44 MJ/kg)
Q_out = P_electrical + Q_coolant
+ Q_exhaust + Q_radiation
ΔQ = Q_fuel - Q_out
Energy balance closure better than ±3 % is the standard for engine calorimetry; we target ±1.5 % via redundant measurement at each station.
3.4 Exhaust spectroscopy (Aim 2)
Three simultaneous instruments:
- Bosch BEA-150 (or equivalent) 5-gas: O₂/CO/CO₂/NOₓ/HC (NDIR + electrochemical)
- MIDAC FTIR with heated transfer line: speciation of HC, NOₓ, NH₃, formaldehyde, methane, water vapor
- Pfeiffer QMG 220 quadrupole mass spectrometer with capillary sampling: m/z 1–200, focused on H₂, He, hydrocarbon fragments, O₂ isotopes (m/z 32 vs 34)
Sampling at TSG inlet and outlet alternately (3-min cycle). NIST-traceable calibration gas at start and end of each test.
3.5 Inner-sphere material analysis (Aim 3)
Disassembly schedule: hours 0, 25, 50, 100 of cumulative TSG operation.
At each interval:
- Remove inner sphere, photo-document in standardized lighting
- Sample five pre-specified locations (top, bottom, equator-north, equator-south, equator-east)
- SEM/EDS at 20 kV beam at each location: full-frame image + 5 spot-mode spectra each
- Comparison to (a) baseline scans of the same locations from time 0, (b) control sample (unused SS-304 hemisphere from the same supplier batch, stored in the test cell), (c) MFMP’s published “yellow feature” data
Key metric: shift in Cr/Ni/Fe ratios, appearance of elements not in SS-304 (Ti, Cu, Au, etc.).
3.6 Field monitoring (Aim 4)
- 16-channel Bartington Mag-13 fluxgate array on tripod 0.5 m from device
- 1 Hz sampling, continuous over each 2-hour test segment
- Background scan: same array, same location, with engine off
- Gamma counter (GQ Electronics GMC-300S) at 1 m
- Neutron-bubble dosimeter (BTI BD-PND) refreshed weekly
4. Expected outcomes
| Test scenario | Conventional prediction | Greenyer/EV prediction | PUM-cosmology prediction |
|---|---|---|---|
| Aim 1 calorimetry | Energy balance closes within ±2% | Modest excess heat (~5%) detectable | Large excess heat (10-30%) |
| Aim 2 exhaust | Reduced regulated pollutants, no anomalous species | Reduced + anomalous isotopes / radicals | Plasmoid emission spectrum |
| Aim 3 SEM/EDS | Original SS-304 composition; surface oxidation only | Element-ratio shifts in localized features | Specific element signatures matching PUM melting-point predictions |
| Aim 4 magnetometry | Background noise + normal generator EMI | Coherent low-frequency signal correlated with operating state | Resonance at specific PUM frequencies (266.6, 1296, 5184 Hz, etc.) |
A clear “conventional prediction” outcome across all four aims would close the file: TSG is a competent post-combustion treatment device, no novel physics. A clear “Greenyer/EV prediction” pattern would warrant immediate replication at additional labs and constitute the strongest single piece of evidence for ambient-temperature LENR in 35 years.

6. Risks and mitigations
- Risk: Test article does not run reliably. Mitigation: Bendall has published parts list + has 12 years of operating experience; replication is not the bottleneck. Two test articles built in parallel with Greenyer-MFMP advisory access.
- Risk: SEM/EDS shows no anomalies. Mitigation: this is itself a clean negative result and publishable; concludes the central Greenyer hypothesis.
- Risk: SEM/EDS shows anomalies but they’re surface contamination from test cell. Mitigation: control samples + isolation environment + chain of custody handle this.
- Risk: FOIA / academic-freedom concerns. Mitigation: private foundation funding avoids government conflict; pre-registered protocol on OSF before any data collection.
- Risk: Bendall declines to share embodiment details. Mitigation: parts list is already published; Vajra patent is in the public domain; Greenyer’s hypothesis is fully published.
- Risk: Hostile community reaction (mainstream physicists hostile to LENR research). Mitigation: methodology is conventional engineering and materials science; results will be reported regardless of direction.

9. Why this proposal, why this PI
This study is unusually well-positioned because:
- The device is cheap to build (~$700 parts) and well-documented (16-section public lecture series + 17-part published patent application)
- The hypothesis to test (Greenyer’s EV reframe) is independently published and connects to 50 years of established LENR literature
- The experimental protocol is conventional — calorimetry, FTIR, SEM/EDS — accessible to any university materials/combustion lab
- The result is decisive in either direction: a clear negative is publishable and closes a frequently-recycled public claim; a clear positive is the strongest LENR result in decades
- The PI has no financial, ideological, or social affiliation with either Bendall or with mainstream-physics anti-LENR factions; this independence is the central asset
The current state of public discussion of Bendall’s work is dominated by uncritical enthusiasm on one side and reflexive dismissal on the other. The function of this study is to replace both with measurement.
