Original Title: Five Grand Ideas That Will Shape This Century
NetEase Technology News, November 1 — According to a BBC report, asteroid mining, lab-grown meat, seawater-based clean energy, driverless cars that could reduce traffic fatalities, and blockchain technology that might replace traditional banks are five groundbreaking innovations that will soon reshape the world — and faster than we think.
1. Lab-Grown Meat: A Greener Future for Food
Imagine a future where burgers are grown in vats instead of on farms. Scientists extract animal stem cells and nourish them until they develop into edible tissue — this is the concept behind lab-grown meat, also known as "cultured meat." While it may sound strange, it's far more humane than traditional livestock farming, as no animals are killed in the process.
Additionally, lab-grown meat has a significantly smaller environmental footprint. A 2011 study showed that producing 1 kilogram of lab-grown meat requires 200 times less land, about 30 times less water, and half the energy compared to raising a cow for beef. In 2013, the first lab-made burger was cooked and eaten in London, marking a milestone. Recently, a U.S. startup announced success in growing chicken and duck meat in labs, with plans to sell the product by 2018. Although the cost is still high (around $19,800 per kilogram), it's rapidly decreasing.
2. Driverless Cars: Saving Millions of Lives
Every year, over 1.2 million people die in road accidents worldwide, with nearly 40% of those deaths occurring in China and India. Most of these incidents are caused by human error, from speeding to distracted driving. Experts believe that replacing human drivers with autonomous vehicles could prevent up to 90% of these accidents, potentially saving over a million lives annually.
Elon Musk predicted that fully automated cars would be available by 2019, but others suggest it may take until 2026 or later. While challenges like hacking and ethical dilemmas remain, driverless cars promise safer travel. You won’t have to worry about texting while driving or fighting over the steering wheel — you could even sleep during your commute.
3. Blockchain: Revolutionizing Finance for All
Two billion adults lack access to traditional banking due to cultural, economic, or geographic barriers. Blockchain technology offers a solution by enabling peer-to-peer transactions, savings, and loans without the need for banks. Cryptocurrencies like Bitcoin are already changing how people manage money, especially for low-income individuals who can now start businesses, apply for insurance, or send money globally with ease.
Blockchain isn’t just for finance — it’s being used to secure voting systems, track land ownership, and improve government transparency. While its full potential is still unfolding, its impact could be transformative, provided it is implemented responsibly and inclusively.
4. Seawater: A New Source of Clean Energy
Nuclear fusion, which powers the sun, holds immense potential as a clean energy source. Unlike fission, which produces radioactive waste, fusion generates minimal hazardous byproducts and uses abundant fuels like helium found in seawater. The energy produced per gram of fusion fuel is far greater than coal or uranium, making it an attractive alternative for sustainable power.
Despite decades of research, scientists have yet to achieve a net energy gain from fusion. However, projects like the international tokamak in France aim to produce positive energy by 2025. While commercial use may still be years away, the long-term benefits of fusion energy could revolutionize global power systems.
5. Mining Asteroids: The Next Frontier
Asteroid mining may sound like science fiction, but companies like Planetary Resources are already working on it. These space rocks contain valuable minerals such as platinum, gold, and water — a key resource for future space exploration. While the costs are high, the potential rewards are enormous. One asteroid alone could provide more platinum than the entire world currently produces.
Experts predict that by the mid-2020s, we may begin extracting water from asteroids, paving the way for sustainable space colonies and deep-space missions. Though still in its early stages, asteroid mining could become one of the most lucrative industries of the future.
TFT (Thin Film Transistor) is a thin film field effect transistor. The so-called thin film transistor means that each liquid crystal pixel on the Liquid Crystal Display is driven by a thin film transistor integrated behind it. This can Display Screen information at high speed, high brightness, and high contrast. TFT is an active matrix liquid crystal display.
The TFT-LCD liquid crystal display is a thin film transistor type liquid crystal display, also known as "true color" (TFT). TFT liquid crystal has a semiconductor switch for each pixel, and each pixel can be directly controlled by dot pulses, so each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display, but also can be accurately controlled Display color gradation, so the color of TFT liquid crystal is more real.
In the fierce competition among many flat panel displays, why TFT-LCD can stand out and become the next-generation mainstream display is by no means accidental, it is the inevitable development of human technology and thinking mode. The liquid crystal has avoided the difficult light-emitting problem successively, and the light-emitting display device is decomposed into two parts by using the excellent characteristics of the liquid crystal as a light valve, namely the light source and the control of the light source. As a light source, brilliant results have been achieved in terms of luminous efficiency, full color, and life, and they are still being deepened. Since the invention of LCD, the backlight has been continuously improved, from monochrome to color, from thick to thin, from side fluorescent lamp type to flat fluorescent lamp type. The latest achievements in luminous light sources will provide new backlight sources for LCDs. With the advancement of light source technology, newer and better light sources will appear and be applied to LCDs. The rest is the control of the light source, the technology and process of the semiconductor large-scale integrated circuit are transplanted, the thin film transistor (TFT) production process has been successfully developed, the matrix addressing control of the liquid crystal light valve is realized, and the light of the liquid crystal display is solved. The cooperation of the valve and the controller enables the advantages of the liquid crystal display to be realized.
