From an InterestingEngineering.com online article:

With encouragement from his boss, Motorola’s chief of portable communication products John Mitchell, Cooper and engineers at Motorola produced the working prototype for the first cell phone. On April 3, 1973, before stepping into a news conference in Manhattan to demonstrate the new device that would go on to revolutionize communications, Cooper placed the first cell phone call in history.
While cell phones are a fairly modern invention–if you consider 1973 ‘modern’–the idea of a telephone that could travel with you is as old as the telephone itself. For decades though, the best anyone could offer were bulky two-way radio devices that were essentially walkie-talkies that filled the trunk of your car, but a couple of key engineering developments and a classic American business rivalry would help lay the foundation for the device that revolutionized the way people communicate.

A startup called Bumblebee Spaces is trying to make micro apartments more appealing by adding movable furniture. Beds, wardrobe and drawers are stored up on the ceiling, to be lowered quietly on white suspension cords at the touch of a tablet, like a scene change on a theatre stage. In theory this frees up floor space. Once he’s raised his bed in the morning, Dabdoub sometimes does yoga and meditation. In the evening, he can sit on the couch and project Netflix onto a blank wall, which would otherwise be occupied by the bed’s headboard.
Technologists, particularly those who make consumer products, will have a strong influence over how we’ll live tomorrow. By treating older adults not as an ancillary market but as a core constituency, the tech sector can do much of the work required to redefine old age. But tech workplaces also skew infamously young. Asking young designers to merely step into the shoes of older consumers (and we at the MIT AgeLab have literally developed a physiological aging simulation suit for that purpose) is a good start, but it is not enough to give them true insight into the desires of older consumers. Luckily there’s a simpler route: hire older workers.
Here’s how Airport’s service works: A passenger checks in online. The company collects the bags from their doorstep after confirming the person’s identity. The driver puts the bag in a coded, tamperproof, and trackable security bag, the company said. The driver delivers the luggage to the airport, where they check in the bag.
The difference is simple. There is nothing else like Living Vehicle. Every inch is designed and built without compromise. Our mission is to create a Net-Zero vehicle capable of supporting the best possible human life. No energy in, no waste out. We are guided by this vision and grow closer to this goal every single day. 
Going far beyond industry standards, 2020 introduces a Living Vehicle with unprecedented capabilities. We’ve partnered with the most advanced and innovative products from the military, disaster relief and marine sectors and now have several patents pending. From being able to power the AC with solar to technologies that create life sustaining resources, the 2020 model is a true functional work of art.
