This short articles describes how to find how many shells needed in series that would be sufficient to perform the duty required.

Hyundai tech reduces cabin noise by three decibels November 13, 2019
Hyundai has revealed details of its new noise cancellation technology, a claimed world-first that’s been six years in the making. Known as RANC (Road-noise Active Noise Control), it uses velocity sensors, amplifiers and microphones to calculate vibration and noise from the road, then uses a digital signal processor (DSP) to produce an inverted soundwave to […]
Perovskite solar cells have new potential November 13, 2019
Researchers in Saudi Arabia have used computational modelling to determine the best materials for perovskite solar cells, an advance that could add commercial viability to the promising power source. Perovskite solar cells can be cheaper and easier to produce compared to silicon solar cells, but they lack long-term stability, and this has hindered their progress. […]
Superconducting wind turbine passes first test November 13, 2019
The turbine, which uses high-temperature superconductors in its generator, could form the basis of future high-capacity wind energy systems A Denmark-based consortium called EcoSwing has designed, developed and manufactured a full-size superconducting generator for a 3.6 MW wind turbine, and subjected it to its first trial in which, as they report in the journal Superconductor […]
