A Little History about the Electric Garage Door Opener

Ever wonder where the electric garage door opener came from?  Believe it or not, it was invented as early as 1926 complements of inventor C.G. Johnson from Hartford City, Indiana. I imagine being from the Midwest he probably came up with it after tiring of having to exit his new Ford Model T Speedster in the hard cold winters to open his manual garage door in several inches of snow.  Having grown up in the automobile capitol myself with a manual garage door, like many, I am grateful for this wonderful creation.

EN-V - Concepts Of Electric Vehicles For The City

All three concepts were presented in Shanghai and so are the Chinese names - Yaao (Pride), Miao (Magic) and Xiao (Laughter). All the models on the intention of the authors should use the motors with the possibility of charging a lithium-ion batteries from an ordinary wall socket. One charge should be enough for a 40-kilometer trip (to the office and back with a stop in a shop, restaurant or anywhere else can go after work, man). If desired, the driver can pass control to on-board computer that uses GPS-navigation. Pay attention to the dashboard instead of the usual steering column - it can be hidden in the armrest. Authors EN-V argue that electric can turn a 10-cents coin, and quite independently bring in the right place its passenger, using the built-in GPS.

 

Electric mini-farthing

The yikebike can comfortably be ridden by anyone from 160cm to 195cm (5’3” to 6'5"). There is no need to adjust the seat because you do not pedal – your height relative to the seat is only important to how much your knees are bent when riding. The bike can comfortably take a rider (and personal effects) weighing up to 100kg.




The 'yikebike' by inventor grant ryan and engineer peter higgins of new zealand, is a mini-farthing bike designed to battle the increasing urban congestion of today. The carbon fiber frame is the foldable and weighs under 10kg. Yikebike's electronic motor allows you to travel at speeds up to 20 kph. The design means that your feet remain static on the footrests and your fingers work the accelerator and a brake.
