On the propulsive force developed by asymmetric capacitors in a vacuum

Physics Procedia, 2011
AbstractThe present work provides a detailed analysis of already published reports on the observation of an anomalous force in a vacuum associated with vacuum sparks in asymmetric capacitors charged with “constant” high voltages. Known experimental details of these experiments are put forward and propulsion performance is compared with the only known ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

Advanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...
