#Guazi used cars

Xiao Zhao takes an order: make me a Dongcheng battery, 20V with 2000 cells, deliver to the 23rd floor when done. Grab purple-wrapped cells and a yellow holder, spot weld (DA DA DA), case it; labelling: no label looks unprofessional, ‘let’s get professional’, stick on the 20V (20Ah) label, now it looks the part; 130 (yuan), little sister takes the battery up to the 23rd floor; the square impact socket set goes to one side; her e-scooter dies one block out and she pushes it back, call a courier? how much can this order make and we’d hire a courier; take my car, petrol costs more than a courier; ours is electric, no petrol, just bought from Guazi Used Cars for only 99k (placement: official inspection, OEM warranty on the three electric systems, 100-day battery-degradation guarantee); a scatterbrained day, this family would fall apart without me. Another battery ‘this one’s no good now’, put back as it was, 80; done, 50. Sister comes back, the car’s in nice shape. Imported STIHL 381 chainsaw: an old sawyer managed to fit the chain backwards; won’t start, swap one; too much oil too, not turning so look at the brushes, rotor isn’t great; 10 yuan; screws all gone makes it easy, pull the battery first; 5 yuan; the all-rounder, 10 yuan, take it slow. 1812 comments: fix this for me (150), Bosch drill burned drilling steel, can I mail it in (99), you dare let sister deliver, not afraid it goes dark (37), they asked for 20V and what’s yours (2, about the 20V20Ah label); how big can a Metabo 18V go.

The previous generation, a turbojet built from a car turbocharger, reached self-sustain (0.0009 t of thrust, on LPG alone) and then blew its intake-side pressure hose after a dozen seconds. This time the intake is metal elbows joined and polished, sealed with aluminum tape; the bearing oil loop gets 120°C / 3.2MPa high-strength pressure hose with a pump circulating the oil. Because rich-oxygen combustion was wasting oxygen, an afterburner goes on the tail: a can cut up and steel tube sleeved over it — the tube was so thick he spent ¥3000+ on a higher-power welder before it would take a weld; a necked-down outlet adds thrust; a branch fuel line with several injection holes is tied into the main line so preheated fuel partly enters the afterburner for a second burn; a relief valve on the intake side guards against runaway rpm. A Guazi used-car ad is cut in midway. Test run: after self-sustain the shaft suddenly seizes, thrust hits 0.0023 t (more than double the last gen); opened up, the shaft spins freely again — suspected dust or over-speed, so a bigger steel-tube relief valve is added (screw sets the tension). The retry lacks pressure; he plugs it and patches leaks, but in the end it never self-sustains again — “give me my money back, I quit” — and looks ahead to gen 15.
