    "device_name": null,
    "goal": "Explain and harness the properties of the newly described exclusion-zone (EZ) phase of water for biological and energy-related applications.",
    "problem_addressed": "Conventional science treats water as a simple H_2O liquid, overlooking a structured phase that may store charge and energy, which limits understanding of cellular processes and potential energy technologies.",
    "concept_summary": "Pollack proposes a fourth phase of water, called exclusion-zone (EZ) or structured water, with a chemical formula H_3O_2 and a hexagonal crystalline lattice. When water contacts charged or hydrophilic surfaces and is exposed to light (especially infrared), it forms layered sheets that exclude solutes, acquire a negative charge, and can store electrical energy similar to a battery.",
