A 300 Watt pico hydro turbine can be purchased in Vietnam for as little as $20 and will meet the electricity needs of a whole family. There is no need in most cases for expensive battery storage since the power generation is constant 24 hours a day 365 days of the year.
A mixture of 90% HFO1234ze (E) and 10% SF6 has a critical electric field of 360 Td, similar to pure SF6. We attribute this effect to the high efficiency of HFO1234ze (E) in moderating down the electron energies, which enhances electron attachment to SF6 and reduces electron impact ionization.
