Expect hundreds of megabits per second, maybe even a gigabit, even in sparsely populated areas — as long as homes are near power lines.

The world’s largest offshore windfarm has officially opened. The project commanding the Numero Uno status is the Walney Extension. An official inauguration was marked as September 6, and it now means that the Walney Extension overtakes the London Array as the world’s largest offshore wind farm.
How large? Stats say the farm, located in the Irish Sea off the Walney Island coast in Cumbria, covers an area of around 145 sq km (55 square miles). Project watchers are talking electricity for nearly 600,000 UK homes. It’s especially being touted as having been built on time and on budget.
It’s also being described as a “659-megawatt project.” The Danish company Orsted, PKA and PFA are the names behind this project.

One day in the not-so-distant future, light sails may hurtle through space at speeds of around 20% of the speed of light (or 60,000 km/sec), propelled not by fuel but rather by the radiation pressure from high-power lasers on Earth. Traveling at these relativistic speeds, laser-powered light sails could reach our nearest neighboring star (other than the Sun), Alpha Centauri, or the nearest known potentially habitable planet, Proxima Centauri b, in about 20 years. Both objects are a little more than four light-years away.

This video is the first in a two-part series discussing 5G. In this video, we’ll be discussing the many many aspects of current generation mobile networks that 5G is set to improve.
As well as the technologies and communication techniques that will be required to enable these upgrades in speed, latency, bandwidth, energy consumption and more!
[0:35–8:15] First we’ll take a look at the core technologies that 5G is composed of, how they work together and the benefits they will each bring.
[8:15–11:50] Following that, we’ll look at the upgrades 5G will bring to current mobile generation speeds, latency, bandwidth and energy consumption.

We are undeniably using up what little remains of Earth’s petroleum, and because of that, it’s getting expensive. To reduce fuel costs, shipping companies are turning back to sailboats. Yes, seriously. Sailboats. But they don’t look like any sails you’ve seen before.
You know sails – most of the time big rectangle things, sometimes big triangle things, almost always (but not always-always) made out of cloth. But while those things in the top gif don’t look like your normal sails, that’s what they are. They just don’t work like any sail you’ve ever seen before.
Most sails you’ve seen rely on the wind directly acting against them to provide propulsion. But these new types of sails, known as “rotor sails” rely on a physics principle called the Magnus Effect. Here, I’ll let the people with delightfully thick Finnish accents from Norsepower, the company that makes them, explain it:

A sapphire-colored dye called methylene blue is a common ingredient in wastewater from textile mills.
But University at Buffalo scientists think it may be possible to give this industrial pollutant a second life. In a new study, they show that the dye, when dissolved in water, is good at storing and releasing energy on cue.
This makes the compound a promising candidate material for redox flow batteries—large, rechargeable liquid-based batteries that could enable future wind farms and solar homes to stockpile electricity for calm or rainy days.

Scotrenewables Tidal Power, a Scottish engineering company, is focused on an energy source they call “tidal energy generation.” A video promoting their solution: They have plenty to show for their efforts, namely, the world’s most powerful operational tidal turbine, the SR2000 2MW.
A reduction in manufacturing and installation costs plus simple, quick and low cost maintenance strategies will be key to success.
The company release said, “Scotrenewables Tidal Power has set another record with its first 2MW floating tidal stream turbine with the unit clocking up over 3GWh of renewable electricity in its first year of testing at the European Marine Energy Centre (EMEC) in Orkney, Scotland.”

How 5G Will Change The World! https://www.facebook.com/singularityprosperity/videos/438504459964467/
In this video, we’ll be discussing 5G – more specifically, what it is and its ability to change our world!
5G is a core technology in establishing the digital infrastructure of the future and will be essential in how all of the over 50 billion mobile and connected devices by 2020 will communicate together!
[0:25–2:55] First we’ll take a quick look at the history of mobile networks, and how they have evolved over the years to present day.
[2:55–14:20] Following that, we’ll focus on the technologies a 5G network is composed of and the improvements in speed, latency, bandwidth and energy consumption they will bring.
