New air-free tires will be made of fully recyclable thermoplastic-resin spokes, making them completely immune to punctures. Wider spokes will radiate from the center of the tire to the radius, where the spokes will attach. The spokes will curve from left to right as they will extend from radius to the tread, creating a balancing force that will not distort the tread.

Website creation is a time-consuming and complicated process on the one hand, but exciting and interesting on the other hand. What do you need to create a website? What are the main stages of work? How could the idea be materialized in the website which is interesting for visitors? Website creation process consists of several stages: 1. Defining goals of the Internet Project for which the site is going to be created and its potential audience. The site can be defined as...

Each of us once in life wanted to leave the stuffy apartment and to go somewhere outside the city, away from the smog and the exhaust to breath with pure sea or mountain air. Even in perfectly clean apartment with a daily wet cleaning and airing we still suffocate and feel that we do not have that pure air. Why is this happening? There are particles in the air which are called air ions, positively and negatively charged. They are ranked as light, medium, and heavy. The...

People often use a flashlight to make some notes at night in a place where there is no electricity (for ex., during a hike, fishing or in some other place). They just fit it in some way and make records. This seems to be very inconvenient. A small light bulb, 3 feet of bell wire, a flashlight battery and a pen, connected to the circuit shown in the attached figure, allow you to make notes in the pitch darkness. One more advantage of this solution is that one can write with such a tool...

The suitcase will communicate with a smartphone to automatically follow the user, even locking itself and sounding an alert if it gets lost. The suitcase will move about on small set of treads powered by compressed air and will include a microcontroller able to identify and triangulate signals from the user's smartphone. It will follow at a constant distance, and will lock itself and send a vibration alert to the phone if the signal is lost. The bags can also be programmed to...

As soon as the ski season is finished, skis should be put away so as not to be damaged during the summer. First, remove the old grease from the skis. To do this you need a clean rag, gasoline or kerosene. Do not wet the rag a lot as you can spoil the top of the skis. After removing the old grease, let the skis dry. Then tar the skis heating them with a blowlamp. On a hot sunny day it is good to "warm up" skis, placing their work surfaces to the sun. In the sun the...

Either you want to glue something, to bind up a book or anything else you always need a press. I attached the picture with three simple press designs. You can choose any. Each construction creation require only a few minutes.

A wireless system for monitoring bridge integrity will transmit minute-by-minute updates and will cost as much as one-hundredth the amount of wired network. The sensors will be made up of four flexible layers and will be less that 5 millimeters thick. The different layers will measure parameters, store energy, transmit the data, and harvest energy from ambient light and radio waves. The sensors will be strong and self-adhesive and will require no wires or batteries since they will...

I've already posted the idea with several simple press designs. They are all easy to be created but have one main disadvantage: they can be used only with flat materials such as books. But what are you supposed to do if you have to stick a piece of plywood on a curved surface? I suggest you using a simple bag of sand as a press. And also do not forget to put a paper insert between the plywood and a bag.

If the skates are not ground down properly, you will not achieve a real speed no matter how hard you try. Skates with a wide blade can be ground down with a thick round file or an emery stone rotating in the machine. Only sharp skates allow you to feel comfortable while skating on the ice and, of course, to develop the maximum possible speed. So do not let yourself go skating with blunt skates! Grind down your skates regularly!
