Quantum network will provide billions of people secure and fast connection. Researchers have yet to incorporate into it nodes of different types to make a bright quantum future the case.

And here we have a breakthrough, one in building a hybrid quantum system. Researchers managed to pass a qubit, a unit of quantum information, from one node based on cooled gas to another based on a rare-earth doped crystal. This is a sure sign of progress, so let's see how the work can be advanced further to consumer-oriented devices.

In the study researchers report they also changed the wavelength of a carrier of a qubit, i.e. a photon after generating it to fit into a conventional optical fiber used to link the two nodes. Upon receiving the wavelength was changed second time to match that of the receiving crystal itself.

Finally the team reports successful encoding.

"We demonstrate that quantum correlations between a photon and a single collective spin excitation in the cold atomic ensemble can be transferred to the solid-state system.

"We also show that single-photon time-bin qubits generated in the cold atomic ensemble can be converted, stored and retrieved from the crystal with a conditional qubit fidelity of more than 85 per cent.

"Our results open up the prospect of optically connecting quantum nodes with different capabilities and represent an important step towards the realization of large-scale hybrid quantum networks.

What is the next step? As we are at ReptileCoin community going to provide our users with advanced quantum networks we need more research in this field, especially we aim to find ways of reducing costs for mass user. Therefore work to be done includes surveying and comparing different types of quantum nodes available. Looking at them in the perspective of being used as components of a network to come is to be in the focus of research we need and are going to support. It is being a part of a bigger network that might have impact on weighing pros and cons of different physical platforms representing nodes.

This time we are looking at ways of delivering our clients energy on mass scale that comes from renewable sources and is green, among other products to come from ReptileCoin community of developers.

Let’s have a look at a new device that produces electricity and at the same time serves as a storage. The device was recently made by a team and is so new there isn’t a name for it. Before we look at how it works, we are going to elaborate a little on what mass consumer wants. It’s time when we have to develop and deliver to the whole planet solutions that are effective, green and don’t pollute the air, soil and ocean. Our users want affordable and inexpensive things to use daily and be happy with them.

By effectiveness we mean the device powering other stuff has to be effectively obtained from renewable sources, which are many. Green solutions are those that are friendly to the environment. And besides its manufacturing, the product’s lifecycle doesn’t have to put unwanted pressure on nature. We orient towards the demanding consumer and all the more is bigger challenge for our developers.

So by far we have a product, a hybrid one, that promises to fit the high requirements to bring the whole of our planet to a genuinely green world and provide everyone with power effectively.

The product of team research work is described as an integrated solar-powered system for both electrochemical energy storage and water electrolysis. That is a user will be able to use it both as a battery, or supercapacitor and as a hydrogen fuel cell.

The team has placed a nickel-cobalt-iron layered double hydroxide (Ni-Co-Fe LDH) on a substrate of nickel foam. The unique mesoporous structure of the LDH enables more charge/ion diffusion pathways and available active sites which contributes to the high performance of this novel material.

The Ni-Co-Fe LDH plays role as an active electrode material in supercapacitiors first and as a catalyst in the oxygen evolution reaction (OER). The paper notes its remarkable electrochemical properties:

When employed as the positive electrode in a supercapacitor, along with activated carbon as the negative electrode in an asymmetric configuration, the ultrathin and porous Ni-Co-Fe LDH nanoplatelets delivered an ultrahigh specific energy of 57.5 W h kg−1 with an outstanding specific power of 37.9 kW kg−1 and an excellent cycle life.

As an OER electrocatalyst, Ni-Co-Fe LDH exhibited superior electrocatalytic performances with a very low overpotential of 0.207 V versus a reference hydrogen electrode (RHE) at 10.0 mA cm−2, and a small Tafel slope of 31 mV dec−1.

So we have here a dual-functional device; a claim has been made for the device to become the major energy device of the future. This claim is backed by using such earth-abundant elements as cobalt, iron and nickel. Summarizing, researchers has wired up the device to a solar cell for simultaneous successful energy harvesting and storage. An “excellent cycle life” has been claimed as well.

Before the device can come to homes of billions of users in the form of consumer electronics some work has yet to be done. First of all, is this thing safe? Is it easy to be manufactured on mass scale and be maintained by user?

To go ahead and come up with new devices based on the novel Ni-Co-Fe LDH platform developed we need to ask some more questions and carry out a lot of work.

First, this is research into what there is demand for. True, people can use this device to power their cars. Can this device be used both in hydrogen and electric cars? It’s up to research.

Next, in our ReptileCoin community one of our objectives is to produce consumer wallets, ATM and payment terminals to promote electronic payment systems everywhere.

Central to life of many cryptocurrencies – not to all – is the process of mining. Mining is the process of finding a solution of a very difficult mathematical problem, to put it simply. And the more electronic cash spreads the more hash power is needed, the higher grows demand for power for miners which are the devices that make these cryptocurrencies tick.

Key to our community is funding ways to provide our users with high quality products that are safe, green and make those using them happy. The dual-function energy device proposed may be used in powering say mining facilities for mass users as a kind of service delivered by our developer community.

The device has been synthesized by the team lead by University of California, Los Angeles (UCLA). read paper

We need as the next step to focus on newly designed research that will put the device to the test to see its capabilities, and especially if it fits the high requirements, being tested in a large scale setting. In the focus is the question of mass production, finding ways to produce it on large scale and have the whole lifecycle without putting pressure on the environment. That’s what our consumers are going to like. And we need to ensure this is the case.

The device is not yet bio-inspired, either. So can we do better? To bring this tecnology closer to biologically compatible - which is our community's ultimate goal - we need more research as well.

If you have ideas on the research design, let us know: send us a letter or post your comment.

How we can have our pets speak - let's look at advances in neuroscience that can highly likely lead us to a position of being able to develop speech in any creature having brains.

What happens in the brain when we hear something? Researchers took a patient who plays a piano well and recorded his brain activity when playing.

Then they turned the sound off and the same was done once again: this time the sound existed only in the brain. The striking results may suggest a way of developing a certain area in the brain that can compose music. And then a human - or any other creature with brains - can play the music by using mental power only. The sound of the music can be scanned or read from the brain directly - and music can be played out loud, in the form of sound waves and be heard by others.

Another way of advancing this result is to try to develop certain areas of the brain to reflect ideas we usualy express through words, that is speech. And then process the sound generated in the brain in a similar way - convert or translate the activity into sound that can be heard.

It is worth working in this direction to make a device that is able of reading brain activity in a creature and translate it straightaway into speech understandable by others.

Actually we might want to have this kind of reader-translator as we want to please all people keeping whatever pet they keep - dogs, cats, parrots, snakes, lizards, tortoises, even fish!

The goal at that is to make owners of pets even happier by enabling their pets with ability to sing songs, speak and have conversations.

Lets get back to the study which however was done on humans.

First, the participant played two piano pieces on an electronic piano with the sound volume of the digital keyboard on. Second, the participant replayed the same piano pieces, but without auditory feedback, and the participant was asked to imagine hearing the music in his mind. The result is similarities between perception and imagery was found.

The experiment done was a pretty simple one. Of our interest are ways to advance it.

The first thing we need to do is to determine what makes the two conditions different. That is to determine different mechanisms in the brain that are involved in a) generating music that is imaginary, unheard and b) actual hearing the sound in physical form. We are going to support this research and get involved in it many different teams.

The original paper is called "Neural Encoding of Auditory Features during Music Perception and Imagery: Insight into the Brain of a Piano Player". In terms of authors this research task is laid out this way:

"It remains unclear how the human cortex represents spectrotemporal sound features during auditory imagery, and how this representation compares to auditory perception.

This is the first turning point for further research.

The second is to replace recording electrocorticographic signals from electrodes in the brain with more suitable non-invasive technique to move towards developing devices for mass user, ones doing scanning and translation.

And the third turning point in research work to be done. We first focus on music, on auditory information that is reperesented by high and low frequency sounds. In more advanced research we are going to work on linguistic information, on its representation in the brain and ways to scan and translate it to be able to recreate it to be heard.

To save the world – and the human race from extinction- scientists propose to drill supervolcanos.

A supervolcano eruption could devastate humanity, the main threat being starvation all over the world during volcanic winter. One way of thinking about ways to prevent the apocalyptic scenario is to make sure we know exactly what is the trigger causing the eruption and to try to turn it off.

So what we can do about the danger and what research we need in order to be able to come up with a working plan - let’s get into it.

The Yellowstone National Park in the US is famous for hot springs. Through them heat leaks out of gigantic magma chambers under the ground. What is of interest is how we can utilize this heat. The prevailing belief is that humanity can calm supervolcanos down by cooling them down: there is a threshold in the amount of heat that accumulates inside a supervolcano after reaching which an explosive eruption happens. Therefore to prevent it from happening we need to make a supervolcano into a geothermal plant.

Lets consider this option. We drill far down inside a supervolcano in multiple places. Then we pump water down under pressure. The water is heated deep inside and comes back in the form of steam. We get energy through using turbines and obtain finally electricity.

Sounds well: instead of having a colossal bomb just underfoot we get electricity and can power whatever we want. But this sketch of what can be developed further into a plan raises a lot of questions.

First of all the very belief that if enough amount of heat builds up this causes an explosive supereruption needs to be checked. We need research on this.

Up to what depth do we need to drill down inside? In how many places?

What are provable ways to ensure we take into account all the magma chambers that are in play?

What amount of water will a super geothermal plant consume?

Under what pressure is the water going to be pumped down?

What are risks of damaging magma chambers in an undesired way and releasing harmful gases?

These are questions going into the subject of research work to be done in a way that ensure independent scientists are involved. No research of this kind has been done by far. So we are going to address to professionals with different backgrounds to find out how we can go about organizing this research. The discussion of the research to be carried out is publicly open.

One of the major challenges is to confront the corrosive power of volcanic setting. No material known can stand up to the high acidity and liquids in magma for long enough. Water pipes are not going to last for long and this alone makes any plan to harvest heat from supervolcano almost impossible to implement.

Any of this kind of plan is highly likely to come to a sticky end and effort to go to smoke without having developed absolutely new materials able to withstand the severe corrosive conditions inside magma chambers.

We face unprecedented technological challenge to create long-lasting reliable materials of absolutely new type. Let’s take on this task and get these materials developed.  First we can turn to nanotubes made from carbon and explore them as well as other options to be able to build on them needed machinery to be used in volcanic magma chambers.

We organize an expedition towards Yellowstone Park; we have to do it right now. If you are someone who is going to take part in it let you know it is the most dangerous adventure on the Earth,  and the time to go there is now. Join Orbital Train community on G+.

Author’s word.

As my mission on the Earth is to show humanity a way to stars we are going to build Orbital Trains around the planet and let billions settle in over there, on orbit.  My mission would not be completed without Space Musical in which people will find themselves flying to stars. And the first episode takes place in Yellowstone.

Volcanism is the very mass killer who has been behind all mass extinctions on the Earth in which entire species of animals and plants died out. The disaster is underway and humankind in next in line. What has happened to others will happened to us unless we find ways to harness the power rising up from the depth. The objective of expedition is to start arranging thing this way.

If supervolcanos like that awakening deep below Yellowstone Park are to be turned into geothermal plants, electricity should go to our plants where space cars for mass space settler will be produced, shouldn’t it? Besides this spot in North America we have some about 20 of them over there. They are also going to be made into plants. I want the research also to find out friendly to environment ways to operate over there.

Our goal is to make our way to stars so let's go ahead and let brilliant artists gather together in Space Musical and sing about it to make sure the whole humanity has got the message. The scenario of Space Musical is the scenario of you getting to space.

Love will save the world.
