An apparatus detects complex time-variant electromagnetic disturbances resulting from a high-altitude nuclear electromagnetic pulse (EMP) or solar storm. The device relies on a circuit (104, 1301) to monitor the input power lines (301, 401, 501) for sustained conducted electrical disturbances associated with the E3 phase of an EMP or solar storm. A separate circuit (105, 1302) monitors the power lines and the ambient environment (503) for transient electromagnetic pulse disturbances associated with the E1 and E2 phases of an EMP. A housing (901, 902) has a pair of AC mains wall plug prongs (905) extending from a side. When sustained electrical disturbances or transient electromagnetic pulse disturbances are detected, the apparatus provides a visual alarm (603, 609), audible alarm (608), and discrete indication signal (607) that can be used to disconnect (702) or redirect the flow of electrical power.

In various units, a coating of chips or pellets comprising a deuterium-containing micro-fusion fuel material produce energetic reaction products and/or EM radiation in the presence of an ambient flux of cosmic rays and muons generated from the cosmic rays. The chips may contain solid Li.sup.6D or encapsulate liquid or frozen D.sub.2O. Micro-fusion reactions proceed via muon-catalyzed fusion, particle-target fusion, or both. These may produce usable heat for a space heater to heat surrounding spaces directly or communicate via circulating fluid with a heat exchanger located for more remote heating of spaces away from the generator. EM radiation can be converted to electricity, either directly or via heating of a circulating liquid and thermoelectric conversion. Mechanical work may also be performed by the energetic reaction products, wherein a coated panel mounted on a transport vehicle may serve as a propulsion unit, the energetic reaction products directly providing horizontal thrust or providing electricity via heating (as before) to drive the vehicle. Other mechanical devices include paddle wheels coated with the chips to generate rotary motion, and levers coated on one lever arm to produce a beneficial force at the other lever arm.
