What is Marine Energy?

Marine energy (also referred to as marine power, ocean energy, ocean power) refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences. The movement of water in the world’s oceans creates a vast store of kinetic energy or energy in motion. Some of its energy can be harnessed to generate electricity to power homes, transport, and industries.

The term marine energy encompasses both wave power i.e. power from surface waves, and tidal power i.e. obtained from the kinetic energy of large bodies of moving water. …

Chinese artificial sun beats the Korean one by 60 million degrees.

Korean Artificial Sun

It is called ‘artificial sun’ and actually, a more appropriate nickname could not exist: the Korea Superconducting Tokamak Advanced Research (KSTAR) broke all records, maintaining the temperature of 100 million degrees for 20 seconds.

The KSTAR is an advanced research device on magnetic nuclear fusion, built at the National Fusion Research Institute in Daejeon, South Korea. With the aim of studying the possibility of obtaining magnetic fusion energy, it was approved in 1995 but has delays due to the East Asian financial crisis which has significantly weakened the South…

A study presents the display prototype made with compostable materials that will serve to reduce the production of electronic waste.

Among the large amount of waste that is produced every day, particular attention must be paid to the component of electronic waste. The latter, in fact, represent one of the highest percentages of waste that human beings produce in the world and, often, they are non-recoverable disused electronic devices that end up in landfills.

A considerable share of electronic waste is also represented by screens, which are very difficult to recycle. Thus a group of scientists has well thought of solving at least part of the problem of electronic waste by producing an innovative display built with biodegradable materials. …

How can one possibly create electric energy with heat?

I’m not talking about converting water into steam or burning gas to rotate electric generators. Those days were over I believe. I’m talking about “Thermo Electric Generators”. Okay, now What is this Thermo Electric Generator?

Thermo Electric Generator

Thermoelectric generators (TEG) are solid-state semiconductor devices that convert a temperature difference and heat flow into a useful DC power source. Thermoelectric generator semiconductor devices utilize the Seebeck effect to generate a voltage. This generated voltage drives electrical current and produces useful power at a load.

Earth is spinning too fast, breaking records of fastest days in 2020

2020 the year in which the coronavirus pandemic broke out, is finally over. And while for many of us it seemed interminable, this year ended unexpectedly faster. The Earth, in fact, has rotated much faster than the average, with 28 days which have been the shortest since 1960.

Before going into the actual story, I presume everyone knows that our earth spins once around its axis causing sunrisings and sunsets while rotating around the closest star Sun. But if anyone wants to know why does it rotate, here’s a beautiful article “Why Does the Earth Rotate?”. That's totally fine not…

An easier way to import, rearrange, merge, and indexing data from multiple text files along with exporting the combined data.

I presume that you already know how to import data from a single data file. If not no worries we’re going to start with it.

One can import data into python through two methods:

Importing Manually: In the case of JupyterLab, one can simply import data by navigating to File browser (Ctrl+Shift+F) and clicking on the file we need to import. It’s easy right…!
But what if we need data from more than one file?

Importing through Command: This method will be helpful to import data from multiple files. Let’s see how to import data from a single file first.

Computer devices made with mushrooms? A team of scientists believe in it and are working on it.

The Pleurotus Ostreatus also know as oyster mushroom or oyster fungus is a rather common, edible, and considered good mushroom. Also called Oyster Mushroom, Pleurotus mushrooms belong to the Pleurotaceae family and are a species that lends itself well to cultivation.

Scientists found that the electrical networks of fungi of the Pleurotus ostreatus species are excellent, for creating computing networks.

Mushrooms could also be used for wearable technology, for example for sensors that can be applied to clothing, or even for sensor computing circuits. In a study, entitled Reactive fungal wearable and published on Biosystems, it is explained that there…

2020 is the second hottest year on record, just a little colder than 2016.

Finally, the northern hemisphere recorded, in the course of 2020, the fourth most limited snow cover in the period 1967–2020.

2020 was the second hottest year ever recorded on Earth: the official confirmation comes from the periodic analysis published by the US NOAA. 2020 ranks second just behind 2016 with global earth and ocean surface temperature of 0.98 ° C above average.

2020 turns out to be only 0.02 ° C cooler than the record year, 2016.

26 Richest People in the World Own Wealth of the Poorest 3.8 Billion

The world’s economic inequality is growing more and more and Oxfam’s new annual study, taken up by the Times, points this out: the 26 richest people in the world have an amount of wealth comparable to that owned by the poorest 3.8 billion individuals. Last year, on the other hand, the 43 richest people in the world had the same wealth as the poorest 3.8 billion individuals (therefore half of the earth’s population), a fork that has therefore expanded even further.

As Winnie Byanyima, executive director of Oxfam International explains, in most countries of the world, it is the bank…

What is financial independence and what does it mean to follow this path? In this post, I will explore the basic concepts of FI.

What is Financial Independence?

These words may seem not so familiar. Or they may seem unclear.

Financial independence may be a little vague, or even like spam, too good to be true. I’m going to try to simplify the meaning for you now.

Financial independence does not mean acquiring the wealth of the richest man in the world. The journey to FI (Financial Independence) is not just about creating a nice nest egg in your bank account. It’s more about being able to do what you want, when you want, in the way you want. It’s about designing your lifestyle.

Why let’s face it…
