Cell phones are the most common electronic device in the world, coming in various colors, models and brands. However, it is not the same as a TV, its use depends on the battery charge, which is recharged by a mobile charger. Over the years, technology called wireless charging was developed. This method allows the device to be charged without having to physically connect a cable to the cell phone. Instead, the phone is placed on a charging base or dock that uses electromagnetic fields to transfer power to the device. The convenience and durability of this system are great advantages, but cell phones that contain this technology can cost over R$5,000 in Brazil. In my opinion, the price is a bit exaggerated, but I still think wireless charging is a great invention.

What used to be nothing more than theory, today studies have been improved and it is possible for a car powered by a solar panel to exist! How much does a solar powered car cost? The supply of fully solar-powered electric cars for end consumers is still scarce, with many models still in the study and development phase. The North American company Aptera announced the development of a solar-powered vehicle. The expectation is that the product will be sold for US$ 25,900.00. Even projects from more traditional automakers, such as Mercedes-Benz's Vision EQXX, which features photovoltaic cells on the roof to provide additional energy to the vehicle, are still in the conceptual phase. Following this same idea, the North American automaker Fisker sells an electric SUV with solar energy on the roof for US$61,499. Advantages and disadvantages of solar powered car. A car powered by solar energy has the main advantages of sustainability, through the reduction of polluting gas emissions, fuel savings and the possibility of greater autonomy, reducing the need for recharging. Disadvantages include dependence on weather conditions and higher purchase costs than a traditional electric car. Furthermore, the technology has not yet been. 4 models of solar powered cars: *Mercedes-Benz Vision EQXX. *Lightyear One. * Fisker Ocean. *Hyundai Ioniq 5. How does a solar powered car work? This electricity powers the engine which, in turn, runs the vehicle. Even on cloudy days or at night, a battery contained in the car recharges it when stopped.

The Pixie sensor can be used by anyone on a daily basis.

How it works is simple, just stick one of Pixie's points on the object and pair it with the app on your mobile device The application creates an augmented reality map, capable of “visualizing” the environment on your cell phone and seeing a target at each point on the Pixie, in the places where the items are. The company guarantees that the device can track with centimeter precision, and this is the big advantage. It is also much easier to locate lost objects, whether long-distance or close-up. Its disadvantage is that it is a bit high, costing approximately 40 dollars, which converted to Brazil is 110 reais each.

However, despite being a little expensive, I believe that Pixie is very useful for everyday life and very practical to use.

The Segway PT is a dicycle (means of transport with two wheels side by side) invented by Dean Kamen and launched in December 2001, which works based on the balance of whoever uses it. It is an electric vehicle that promised to revolutionize urban mobility. The inventor compared the Segway to the car, which replaced horses and carriages.
The dicycle is easy to maneuver. To propel it forward, the driver must place his weight onto his toes. When you want to brake, just do the opposite movement. In the first generation of Segways, a button was used to turn right or left. In this second generation, simply tilt your body to turn right or left; in addition to being a more robust vehicle. Its use is aimed at urban mobility, where it could represent a reduction of between 71 and 93% in carbon dioxide emissions compared to any motorized or hybrid vehicle.
Unlike regular motorized vehicles, the Segway does not need to be powered by normal energy resources such as gasoline or gas. This factor is perhaps the main benefit of this vehicle, as it directly implies an advantage for the user, who does not have to spend money at gas stations; and indirectly at a global level, as there are no polluting emissions. To start the Segway, its batteries must be charged. And to do this, you don't need to go anywhere or have any specific machine for the function.
The Segway is above all a stable and safe vehicle, it works based on electrical impulses and, as such, does not produce sound.
However, the disadvantages to the user's reference are the market value of the dicycle, it has a very limited longevity for longer distances covered, having to be governed by urban areas, where it is easily portable and there are several places in the world that limit the free circulation of the Segway, which restrict it by requiring the use of additional accessories or which simply prohibit it.
In my opinion, this invention was very genius as it helps mobilize the population and is very creative.

The iPhone (also known as the Original iPhone or iPhone 2G, after 2008) is the first smartphone model developed and marketed by Apple. After years of rumors and speculation, it was officially announced on January 9, 2007, and was later released in the United States on June 29, 2007.

The development of the iPhone dates back to 2005, when Apple's previous CEO, Steve Jobs, conceptualized the idea of a device in which the user can interact directly with the screen. The design evolved in complete secrecy during the next 2 years, before being announced in early 2007. It contains GSM quad-band mobile connectivity with support for GPRS and EDGE data transfer. Although many iPhone features are considered obsolete by modern standards, the device is seen as a representation of the modern mobile phone, removing physical hardware buttons in favor of a touch-based interface. Its successor, the iPhone 3G, was announced in June 2008.

THE HISTORY

In 2005, Apple CEO Steve Jobs conceived the idea of ​​using a Multi-Touch screen to interact with a computer in a way in which he could write directly on the screen. He decided that a triple-layer screen was needed, a very new and advanced technology at the time. This would help in removing the physical keyboard and mouse, the same as a tablet. Jobs recruited a group of Apple engineers to investigate the idea as a side project. When Jobs reviewed the prototype and its user interface, he conceived a second idea of ​​implementing the technology on a cell phone. This entire effort was called "Project Purple 2" and began in 2005.

Apple created the device during an unprecedented and secret collaboration with AT&T, formerly Cingular Wireless. The estimated cost of developing the collaboration was $150 million over a thirty-month period. Apple rejected the project that had yielded the Motorola ROKR E1, a major collaboration with Motorola. Instead, Cingular Wireless gave Apple the freedom to develop the iPhone itself.

Launch

The iPhone was launched on June 29, 2007 in the United States, where hundreds of people lined up outside Apple Stores and AT&T stores days before the devices were launched. To avoid a repeat of what happened at the launch of the PlayStation 3, which caused robberies and even a shooting, police officers were hired to protect the stores at night. It was later made available in the United Kingdom, France and Germany in November 2007, and the Republic of Ireland and Austria in autumn 2008.

Six in ten Americans surveyed said they knew the iPhone's release date.

Design

The design of the original iPhone was centered around a 3.5-inch (89 mm) touchscreen. The original iPhone features two physical buttons that have remained consistent throughout more recent iPhone generations. The device features a metal frame. The back is made of aluminum with a black polycarbonate base. The 2 megapixel camera is located in the top left corner of the back of the iPhone. The headphone jack is incompatible with most headphones without using an adapter. Other models do not have this problem.

The original iPhone is the only iPhone model not available in multiple colors; the other models are available in black or white

The first quantum machine was created in 2010 and considered the most important scientific discovery of the year by Science magazine. The creation was carried out by a group of American physicists and was the first connection point between the visible world and the quantum universe. The discovery was published in the journal Nature.

Quantum computing has evolved since the first theoretical proposals in the 1980s. Some companies, such as IBM, Google and Rigetti, have been pioneers in materializing quantum theory into operational machines.

Some important discoveries in the history of quantum physics include:

Quantum mechanics

The German theoretical physicist Max Planck is considered the father of quantum physics, after explaining that heat radiation occurs in small portions of energy, called quanta.

Quantum atomic model

The quantum atomic model was proposed in 1926 and is known as the "electron cloud model".

USB Flash Drive, better known as a pendrive, is a device made up of flash memory and used to store data. Pendrives are shaped like a lighter and are very useful today, as they are small and offer a large storage capacity.

These devices were created in 2000 to replace floppy disks, which, when compared to pendrives, have a much smaller capacity. To give you an idea, most floppy disks only have 1.44 MB of storage space, while pendrives have capacities ranging from 64 MB to 64 GB. In addition to being faster and more compact, a pendrive is also much more durable. Due to the absence of moving parts, it can last up to 10 years.

USB flash drives are activated when connected to a computer's USB port, which provides the devices with all the power they need to operate. On most machines, device detection is automatic; on some older systems, specific drivers may need to be installed.

Boots that generate energy
Every step you take with these boots generates an electric current. As? Every time we step on the ground, we squeeze sequences of mercury and accumulate energy stored in the heel, enough to charge small electronic devices such as a cell phone.Published on October 10, 2010 at 03:37.
São Paulo - A pair of special boots promises to do more than keep their owners' feet protected and warm - it will also be able to recharge their cell phones. Called the Orange Power Boot, the turbocharged model is capable of transforming the heat from the feet into electrical currents.Twelve hours of walking, dancing or performing any other activity with the boots can generate enough thermal energy to provide the equivalent of an hour of charge for a cell phone. The recharge capacity is directly proportional to the amount of movement performed and the heat generated inside the boots. galoshes

In 2000, Trek Technology, a hardware company from Singapore, launched the ThumbDrive, the first pendrive to be sold, on the market. The new feature had two major highlights: its tiny size (almost equal to a thumb, hence its name) and its, at the time, incredible 8 MB space for you to store your things.

Pen drives can be more than just storage units, offering a series of interesting features. These features are less well known, and range from using the accessory as a key to lock and protect your computer to speeding up your PC through Windows' Ready Boost feature.

What is additive manufacturing?

Additive manufacturing, also known as 3D printing, is a process used to create a physical (or 3D) object by layering materials based on a digital model. Unlike subtractive manufacturing, which creates its final product by cutting away from a block of material, additive manufacturing adds material to form its final product.

Additive manufacturing expedites prototyping, allowing designers, engineers, and manufacturers to quickly refine designs, saving time and reducing costs. Additive manufacturing also enables customized manufacturing and promotes sustainability through the reduction of waste and energy consumption.

Skype revolutionized the concept of video calls over the internet. At the beginning of the last decade, it's very likely that you were swapping ICQ or mIRC for MSN to chat with your friends. However, from 2003 onwards, when talking about video calls over the internet, the first name that came to everyone's mind was just one: Skype. Launched in 2003, the program that today belongs to Microsoft helped popularize VoIP technology in various parts of the world and firmly resisted the migration of chats to e-mails and social networks (such as Gtalk/Hangouts and Facebook) and, more recently, for smartphone apps
