The interlaced video method is introduced on TVr to reduce image flicker. The transmitter Witzleben uses the new standard with 441 lines and 25 image changes, i.e. 50 fields of 220 half-lines. Until the HDTV era the interlace method remains in use. First movie encoder make it possible not to send the TV live, but to rely on recordings. 1938
Streetcars created enormous demand for early electricity. This Siemens Tram from 1884 required 500 V direct current, which was typical. Much of early electricity was direct current, which could not easily be increased or decreased in voltage either for long-distance transmission or for sharing a common line to be used with multiple types of electric devices.

Students and engineers developed several commercially important types of battery. "Wet cells" were open containers that held liquid electrolyte and metallic electrodes. When the electrodes were completely consumed, the wet cell was renewed by replacing the electrodes and electrolyte. Open containers are unsuitable for mobile or portable use.
