Three Ways to Make a Star on Earth

Massive magnets to confine plasma

This year, construction will begin on the 35-nation megaproject ITER, located in France. A doughnut-shaped, powerplant-size reactor, ITER will contain a fusion reaction within a magnetic ﬁeld and siphon oﬀ energy through its metal walls. Scientists hope to have a test-scale reaction running within the next decade.

A reflective wall in a compact reactor

In Lockheed’s design, a row of magnetic coils create a reﬂective wall to contain the plasma. The company’s small-scale reactor allows scientists to tweak experimental setups more nimbly than they can with a reactor the size of ITER. Lockheed says it has already ﬁred up its reactor 200 times but won’t release any data—so whether those attempts were successful remains to be seen. If they were, well, we may all be driving literal Ford Fusions before long.

A micro-explosion ignited by lasers

At the National Ignition Facility, scientists approach fusion diﬀerently. They ﬁre dozens of lasers at a BB-size bead of solid deuterium and tritium. In a billionth of a second, the hydrogen-based fuel collapses into a dense plasma and bursts into a puﬀ of energy. Last year, scientists produced the ﬁrst-ever net positive fusion reaction, meaning they got slightly more energy out of the plasma than they put in.

How do QR codes work?

QR codes allow symbols, phrases and URLs to be hidden from sight. But how do they work? A QR Code (QR stands for ‘quick response’) is a two-dimensional matrix barcode that consists of a series of black modules arranged in a square pattern on a white background. They work by embedding a series of information within preset boundaries, the data being located and identiﬁed by a series of alignment, timing and positional patterns within the code. The codes are read by scanners and smartphone cameras installed with a QR-deciphering software (these tend to be freely available as apps, or in some cases, are natively installed in the phone’s ﬁrmware). In practice, this allows any smartphone user to hold their device up to a QR code and decipher its encrypted data, receiving a message, image or URL link. READ ALSO:- How a speaker works ?

Hyper Automation (New Technology)

Automation is nothing but an amalgamation of two super technologies of this error RPC and machine learning understanding the automation mechanisms and how it is controlled and coordinated using machine learning MBA main Circus of the screen in the year 2020 automation is employed to have a major macroeconomic implication on the market hence top companies need to give up for this convergence in demographic shapes for now company Wipro and Infosys are experimenting with this technology but other companies are not very far behind..

How ASPs works?

The Web and the Internet began to really heat up and receive significant media exposure starting around 1994. Initially, the Web started as a great way for academics and researchers to distribute information; but as millions of consumers flocked to the Internet, it began to spawn completely new business models. Three good examples of innovative models include: • Amazon - Amazon (which opened its doors in July, 1995) houses a database of millions of products that anyone can browse at any time. It would have been impossible to compile a list this large in any medium other than the Web. • Ebay - Online auctions make it easy and inexpensive for millions of people to buy and sell any imaginable item. It would be impossible to do this at a reasonable cost or in a timely manner with any medium other than the Web. • Epinions - Thousands of people contribute to a shared library of product reviews. One of the Web's greatest strengths is its worldwide view a...
