One such solution is EHT. EHT lowers the viscosity of many processes, as it acts as a compensating heat source to maintain

Self-regulating EHT therefore reduces power output as temperature increases and conversely, increases it systematically as the temperature lowers, which in turn leads to improved energy efficiency. |
