HELIOS Phoebus
Solar-powered sovereign mini PC, the off-grid desk node
The Mickai HELIOS Phoebus is the solar-powered mini PC of the energy-sovereign family, the off-grid desk node. A low-draw mini PC in the obsidian aluminium chassis ships bundled with a folding monocrystalline solar array and an internal buffer battery, so it runs the Sovereign Intelligence Operating System on a desk, a bench, or a field table where there is no reliable mains. An MPPT controller charges the buffer battery from the array, and a power-aware scheduler, the same method the HELIOS Aegis runs, draws model size and agent concurrency down as charge falls and lifts them again as the sun returns. Where the HELIOS Phaethon is the laptop you carry and the HELIOS Eos is the power bank that feeds the kit, the Phoebus is the fixed off-grid desk machine, a small sovereign computer that draws its own light. The full SIOS is sealed on the box, the Open Audit Record is signed under FIPS 204 ML-DSA-65 in place, and nothing leaves the unit unless the operator sends it. Phoebus is for the off-grid office, the field station with a desk, the cabin, and the operator who wants a sovereign mini PC that runs on solar rather than a wall socket. The energy-aware scheduling method is the subject of UK patent application GB2612790.2, filed June 2026; the application is filed, and the Phoebus does not carry a separate application of its own. The operator owns the hardware, the keys, and the audit record. No subscription for context or usage. The price you pay on day one is the price you pay for life.
Phoebus, the bright and radiant, is the epithet of the sun in its full light. The solar mini PC carries the name because it is the HELIOS family on a desk, a small sovereign computer that draws its light directly and runs the brains where the grid does not reach.

Conversational and light agentic workflows on harvested solar, scaled to the charge available, signed throughout.
Beyond the standard Windows and Linux workflow, here is what HELIOS Phoebus does with the Mickai SIOS running on the box. Concrete capability per category, with the level the hardware can carry.
The full cooperative of brains on a desk node that draws its own light. The scheduler keeps reasoning, retrieval, and the audit ledger alive at low charge and lifts model size and agent concurrency as the buffer fills. Open Audit Record signed at every commit, sealed on the box.
A folding array charges a 1 kWh buffer battery through MPPT, smoothing cloud and night, and the energy budget is the first-class scheduling constraint. Runs indefinitely under adequate sun, around 30 hours conversational off the buffer in the dark.
IP54 sealed, wide temperature range, no mains required. The fixed desk computer for an off-grid office, a field station, or a cabin, where the HELIOS Phaethon laptop is the one you carry and this is the one that stays.
A low-power monitor off the DC pass-through, document drafting, research, mapping, and field data capture, all on local solar power with the SIOS resident.
8 GB VRAM holds the brain quorum on smaller models within the power cap, or an integrated-graphics build for the lowest draw. Conversational and light agentic latency on harvested energy. OAR signing throughout.
Sealed in the OAR, no egress by construction, no subscription for context or usage. The operator owns the hardware, the keys, the audit record, and the solar that runs it.
- Solar array and internal buffer battery bundled, runs the SIOS on a desk with no reliable mains
- Power-aware scheduler runs the brains inside the harvested-energy envelope, the same method as the HELIOS Aegis (GB2612790.2, filed)
- Low-draw mini PC, discrete GPU power-capped or integrated for the lowest-draw build
- Mickai SIOS sealed on the box, full cooperative of brains within the power envelope
- Open Audit Record signed under FIPS 204 ML-DSA-65, sealed in place
- No network egress unless the operator sends it, no subscription for context or usage
- MICKAI(TM) wordmark etched on the front face
Mickai is held privately by its founder, Micky Irons. One hundred and one UK patent applications have been filed against the substrate, with approximately 2,234 claims across them, on the public UK IPO register under GB2607309.8 onwards. The corpus covers the cooperative architecture, the Open Audit Record, the FIPS 204 ML-DSA-65 signing primitive, the clearance-gated retrieval, the audio dual-layer watermark, the silicon root of trust, and the host-acceptance attestation that lets the Mickai bundle migrate from one machine to another without breaking its signed chain.
Poseidon, the Mickai Sovereign AI SoC. In-house silicon that complements the GPU fabric on every SKU. Carries the OAR signing primitive in silicon, holds the hardware identity and cryptographic root of trust, and sits between the network interface and the GPU fabric so every action that crosses the bus can be policy-checked before commit. Optional on every SKU as the silicon lands.
Pricing TBD. The price on day one is the price for life. No subscription for context or usage. Only paid upgrades through the sandboxed channel, optional.
Launch window: Late 2026
