In 2007, the crew of a Dutch ship crossing the Mediterranean Sea unearthed a well-preserved ancient Greek helmet near the Israeli city of Haifa. As required by local law, the dredging vessel’s owner promptly handed the find over to archaeologists from the Israel Antiquities Authority (IAA).
Now, reports the Greek City Times, researchers have offered new insights on the object, which is the only intact helmet of its kind found along Israel’s coast.
Crafted in the sixth century B.C., the Corinthian armor was likely used during the Persian Wars, which pitted Greek city-states against the Persian Empire in a series of clashes between 492 and 449 B.C.
“[It] probably belonged to a Greek warrior stationed on one of the warships of the Greek fleet that participated in the naval conflict against the Persians who ruled the country at the time,” says Kobi Sharvit, director of the IAA’s Marine Archaeology Unit, in a statement.
After spending 2,600 years on the seafloor, the helmet’s cracked surface is heavily rusted. But scholars could still discern a delicate, peacock-like pattern above its eyeholes. This unique design helped archaeologists determine that craftsmen made the armor in the Greek city-state of Corinth.
According to Ancient Origin’s Nathan Falde, metalworkers would have fashioned the piece to fit tightly around the head of a particular person—but not so tightly that it couldn’t be swiftly and safely removed in the heat of battle.
“The helmet was expertly fabricated from a single sheet of bronze by means of heating and hammering,” notes the statement. “This technique made it possible to reduce its weight without diminishing its capacity for protecting the head of a warrior.”
As Owen Jarus wrote for Live Science in 2012, archaeologists excavated a similar helmet near the Italian island of Giglio, which is about 1,500 miles from where the crew found the recently analyzed artifact, during the 1950s. That headgear—also around 2,600 years old—helped modern scholars determine when craftspeople manufactured the Haifa Bay armor.
Experts speculate that the headpiece’s owner was a wealthy individual, as most soldiers wouldn’t have been able to afford such elaborate gear.
One theory raised by researchers speculates that the helmet belonged to a mercenary who fought alongside the Egyptian Pharaoh Necho II, per the Express’ Sebastian Kettley. Another explanation posits that a Greek soldier stationed in the Mediterranean donned the headpiece, only to drop it into the water or lose it when his ship sank.
Though archaeologists aren’t sure exactly who owned the artifact, they do know that the warrior sailed the seas at a time when Persia controlled much of the Middle East. As Live Science’s Jarus explains in a more recent article, the Persians attempted to invade Greece around 490 B.C. but were defeated near Athens during the Battle of Marathon.
A second attack by the Persians culminated in the Battle of Thermopylae, which saw a heavily outnumbered group of Spartans led by King Leonidas mount a doomed last stand against Xerxes’ Persian forces. (The 480 B.C. clash is heavily dramatized in the film 300.) But while Thermopylae ended in a Greek loss, the tides of war soon turned, with the Greeks forcing the Persians out of the region the following year.
In the decades after the Persians’ failed invasions, the Greek military continued the fight by campaigning against enemy troops stationed in the eastern Mediterranean. Ancient Origins notes that the helmet’s owner was likely active during this later phase of the war—“when the Persians were often on the defensive” rather than offensive—and may have served on either a patrol ship or a battleship.
The helmet is now on display at the National Marine Museum of Haifa.
The Future of IoT in Solar Energy: How Innovative Technology Is Expanding the Solar Sector – 2020 | Cllax – Top of IT
What is solar energy?
Solar energy is the heat and radiant light received from the sunlight. Sunlight that is received is composed of most visible light. This energy is abundant in most of the areas. It is a good source of energy as it is renewable as well as cheap to get. It is harnessed and utilized for tasks such as Water heating, Heating, cooling and ventilation, Process heat, Water treatment, Molten salt technology, and electricity production. The largest practice of the resource is electricity production. That is an efficient source for the purpose.
It is the most excessive source of energy on this planet earth. It can be used in several ways to make life better for human beings around this globe. The main source of solar energy is the sun. It originates from the sun and is then captured using various methods.
How does solar energy work?
Sun has been a point of discussion for mankind. From the first day of mankind, there were different theories that were associated with the sun. It was believed in old ages that the Sun has ultimate power and is running the whole system of the earth. Some people thought that the Sun was God and started praying for them.
Truth is that the Sun has some powers and it also produces energy. Due to the production of its energy many systems of this world are running. For example, the system of our weather is solely dependent on the Sun. Plants need sunlight to do their photosynthesis process. Without the sun all these things are not possible.
Actually, the sun contains photons. Each photon is a pack of energy. The energy that the sun produces is called solar energy and is used by various things in this world. Moreover, it is very vital for the survival of many processes like photosynthesis.
All this energy that is making different processes run is coming from the Sun. Centre of so much energy is the sun because of the nuclear fusion that is taking place at the core of the sun. This nuclear fusion produces a huge amount of energy that is transformed to our earth in the form of heat and light.
This solar energy is then collected via various sources and is utilized in the best capacity possible for all the users. This is a very good source of energy for the world in this modern era where each and every device requires some sort of energy to run. Solar energy is a very clean energy source compared to other forms of energy. It is also renewable and will not damage our environment like other sources of energy.
Solar energy is relatively very cheap as compared to other sources of energy. This technology is getting popular among people and it’s technology is also growing and improving rapidly. There will be a surge in the use of solar energy in the near future.
Types of Solar Energy:
Mainly there are two types of solar energy. Different technologies are used to extract the energy that is produced by the sun. Both of these methods are really common and are used among people according to their ease. These are explained below:
What is cloud computing?
Cloud computing is the delivery of on-demand computing services which includes applications to storage and processing power which have now adopted solar based green data center solutions. Typically cloud computing is practiced over the internet and on a pay-as-you-go basis and it has become cheaper for green hosting.
Clouds may be limited to a single organization (enterprise clouds) like a central bank server. Or it can be available to many organizations (public cloud). Their access varies according to application. A large cloud system can be accessed from wide locations such as Google drive by Google which also plans to adopt to a green data center soon.
One of the most significant advantages of cloud computing is availability. The main server needs to be active in operational hours. Thus, the users can access the service at any time through the network without any problem.
Emerging applications of this remote service are wide. It will be utilized for the data and instructions stored in many AI projects. Its availability and fast access to the whole data makes it practical for such places where the fast response is mandatory.
However, ensuring cloud data security for cloud desktop, QuickBooks server hosting etc. and eliminating malfunctioning is the biggest challenge for the type of computing. Assuring both is the most important step for the setup.
Uses of Solar energy
Solar energy is the fastest growing renewable energy today. Among all the environment-friendly processes of electric production, this is the most practical. Practical in many ways like it doesn’t need too many organizations for control and management like Nuke needs. Also, its raw material or source is sunlight. Which is abundant and has no cost to receive. Moreover, unlike other renewable practices, it is easiest to manage and install. For other methods such as dams need a huge structure. But this is quite simpler to install. And it yields a great amount of energy.
Because of the mentioned properties, it is growing rapidly. A large number of houses, firms, and housing societies have shifted to it. Many are opting for this setup for their energy production.
Solar Energy is used for various purposes. One of the most common uses of solar energy is to produce electricity. Electricity is an important essential in this modern world. There are a huge number of devices that run on electricity and without electricity these electronic devices are useless. Electricity produced in the world right now has many complications. Many countries are producing electricity with the usage of natural resources. So, a lot of natural resources like fossil fuels are wasted for the production of electricity. Many nations are using gasoline and oil for the production of electricity.
All these methods are really expensive for the production of electricity. Moreover, they are not only costing high but they are also making this beautiful world polluted. The environment is an important issue than money in this modern world because changes in the environment have resulted in many new complications and challenges. There are some countries which do not have any natural resources. For such countries production of electricity is really a big problem.
For all these problems related to electricity production. Solar energy comes out to be a viable solution. It does not have any environmental-related challenges and is also a very viable solution for those countries which do not have any kind of natural resources. Moreover, solar energy is also very cheap compared to other sources and it is such a natural resource that is available to the majority of people of this globe. Hopefully, it will solve the problem of electricity production in the world.
Solar Energy is also used for heating the water. As we discussed earlier, energy from the sun is transferred in the from heat and light. So this heat is basically used to generate warm water. There are many countries where the temperature is usually low which results in coldness. This is all done with the usage of solar water heaters. These heaters absorb sunlight and heat the water which is then transferred to the water and then eventually used for different purposes. This is really a good and easy technique that can solve the problem of warm water.
Solar lighting is also becoming very common among people now. People are using solar energy to do lightening of their homes. This is much more reliable, convenient and easy to use for them.
Similarly, solar vehicles are also introduced now. They are also a hot topic for research and development nowadays. Many tech giant companies and developed countries are working on such working models. This will be really innovative if solar vehicles start operating commonly. It will surely lessen the pollution caused by most of the vehicles. Surely, it will make our environment better and clean. Many such bikes and cars have been developed in America and many electric cars can also use solar energy in the future.
IoT – Future approach for the management of solar energy
The use of solar panels has increased worldwide in the last decade. In the coming decades, this pattern will continue up to a 600% to 700% increase. As much as the industry is growing, several challenges have arrived. While fulfilling the power need of the whole society or dealing with a large production, hundreds or thousands of panels are used. More installations mean more endpoints to monitor and guarantee. Monitoring all of them is really a big deal for the administrators. While solar energy companies have depended on manual processes to supervise everything. However, this approach is no longer practical due to the sector’s size and increase.
To cope with the issue, solar energy firms can adopt the Internet of Things, also known as the Internet of Everything. With IoT, solar panels will have Internet-connected endpoints. Those points will be designed with machine-to-machine interactivity. They will track the condition of panels with some regular duration and send the real-time insight report to management teams through the network.
The use of IoT will change the sector dramatically. Experts assert that IoT’s largest contribution to energy industry firms is in the area of predictive analytics and big data. Because these sensors collect large amounts of data, companies can use this information to monitor their installations more closely. In addition, data analysis tools can provide organizations with an opportunity to use past data and more accurately predict future results.
All the data will be stored in a cloud server. That server will also have appropriate commands and programs to be executed in a different situation. If AI is utilized then this network will automatically execute the commands from the main storage. A fast network and practice of the central cloud server will ensure the activity in real-time.
Data-driven using connected devices will bring a wave of innovation in the Solar energy yield. In the future, cities will be smart by the means of IoT. And in such cities, solar energy will be the main production source. From plant to home level, solar will be used for heating homes, electricity production, cooking purposes, and water heating. So, cloud computing and monitoring solar panels will give ease in managing the system.
IoT networks are complex to install. Before integration, you need to connect solar panels to the utility grid. You also need to ensure that your cellular modules, gateways, and web platforms are all integrated properly, without breaks in connectivity or issue in data security.
Solar energy has its own benefits. Cloud computing and the Internet of things will enhance it further. Actually, cloud computing will receive data from installed devices in real-time.
Many countries have started to rely on solar production. So both the technology will be fruitful for them as well.
Artificial Intelligence, machine learning, and self-learning machines will lessen the effort of IT professionals. Automated machines and programs will govern the field. Hence, fewer people will be required and more efficiency will be ensured. Also, this modern type of monitoring will reduce vulnerabilities of outages.

IoT and Smart Gardening Adds up to a More Convenient Life
Anyone who’s been following technology – or even just general – news will have heard a lot about Internet of Things (IoT) or “smart” devices recently. And some might be asking just how much of a real impact will these products have on my everyday life?
The answer, as it turns out, is more than you might think. Individually, smart devices may appear to offer only minor conveniences (with the exception of connected medical devices). But when combined, these items can radically transform the way we live.
For instance, let’s say that the first thing you do upon waking up each day is make a bee-line to the kitchen to brew a pot of coffee. Sure it only takes a few minutes, but what if your coffee maker could begin the brewing process itself as soon as its sensors tell it that you’ve woken up (or maybe when you switch off the alarm clock). You could walk into the kitchen to be greeted by a steaming pot of coffee and have more time to get ready or check the news, before jumping in the car and heading to work.
In the car, you might pop on some music or listen to some drive time radio. However, your mind always wanders to what tasks and issues may await you when you arrive at the office. If your car had reliable 4G LTE connectivity, it could enable you to open your email via voice command and then read the email content to you. If anything urgent pops up, you could use voice commands to craft a reply email or place a call to the appropriate contact to begin resolving the situation immediately.
Once in your office, a wide array of connected devices can make your life easier. A connected printer can not only warn you when you are low on ink but can automatically order replacement cartridges. Connected lighting and HVAC systems can help you conserve energy, and smart security systems eliminate the potential for human error.
When work is over, you have a few hours to yourself to unwind. Perhaps you will play a few holes of golf, tracking your swing statistics using your connected clubs and an application. Or, maybe you will spend a little time out in your garden using smart gardening devices to automatically manage your sprinkler system.
These are just a few of the many products that can help you make small improvements that, combined, will improve your overall quality of life. The IoT has huge implications for businesses in nearly every sector, but it can also make our own day-to-day lives more convenient. Additionally, the advent of LTE chipsets that consume less power at lower cost is driving the smart device market forward at lightning speed. We are only just beginning to see the potential for what innovation manufacturers can dream up.
