Intéressant, ça ouvre des trucs/idées, et c'est une collaboration MIT / CNRS.
Là ils parlent évidemment de courant et aussi chauffage.
Je cite:
In their experiments, they found that even a small voltage — as low as 5 volts — could increase the surface temperatures of their samples (approximately 5 cm3 in size) up to 41 degrees Celsius (around 100 degrees Fahrenheit). While a standard water heater might reach comparable temperatures, it’s important to consider how this material would be implemented when compared to conventional heating strategies.
Le rêve de ma femme, 40°C un peu partout de tout temps ;)
