Take the Displace Wireless TV, for example. This 55-inch 4K TV prototype is completely wireless and runs solely on four batteries, eliminating the need for any cables or remote controls. It even uses vacuum sealing technology to stay in place without mounting brackets.

However, the batteries that power the screen also run the vacuum, so when they run out, be prepared for some movement. On the other hand, we have Li-Fi, a technology that uses light to transmit data instead of radio waves. It's incredibly fast, about 100 times faster than Wi-Fi, although it can't penetrate walls, making it more secure.

While it won't replace Wi-Fi completely, it has its uses in military communication and providing internet access on planes. Lastly, solar panel stickers are revolutionizing the way we generate electricity. These thin and lightweight solar cells are 18 times more efficient than typical panels, making them versatile and easy to install.

You can place them on buildings, drone propellers, backpacks, or use them for disaster relief, providing power quickly and efficiently. From future technologies like nuclear fusion to current innovations like wireless TVs and solar stickers, the future is looking bright for these inventive ideas
