Home automation. I’ve only just get into relay but man, the ability to turn it on or off based on other devices status is just so futuristic for someone that love and still love simplicity and dumb device.
Also ebike. A motorized bicycle that use electric motor to run, doesn’t smell, quiet, and can assist me so my journey isn’t as exhausting? Where is this thing when i ride my bike 16km round trip to my school every day 20 years ago?
Also, even ICE car can be very quiet in low speed, the insulation and exhaust muffle help a lot. I work with car a lot and often time the noise came from the radiator fan, without it running it’s quite hard to tell if the engine is running or not. The only thing electric car ever gonna solve is the tailpipe emission, which is good, but not quite enough.
