 Renewable resources are resources that can be reused and never run out. Fossil fuels are non-renewable energy sources and solar energy is renewable energy. But is gold renewable or non-renewable?

Does the solar battery that stores solar energy work at night or has a time limit?

A solar panel, or photo-voltaic (PV) module, is an assembly of photo-voltaic cells mounted in a framework for installation.

In 1839, the ability of some materials to create an electrical charge from light exposure was first observed by Alexandre-Edmond Becquerel. Though the premiere solar panels were too inefficient for even simple electric devices they were used as an instrument to measure light. The observation by Becquerel has not replicated again until 1873 when Willoughby Smith discovered that the charge could be caused by light hitting selenium. Now, most solar panel systems attach to the grid and combine net metering where it’s available. Also, installing battery storage is rising increasingly. These two indirect methods can work together at night to increase your energy security and decrease electric bills.

Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), which forms a soluble tetrachloroaurate anion. Gold is insoluble in nitric acid, which dissolves silver and base metals, a property that has long been used to refine gold and to confirm the presence of gold in metallic substances, giving rise to the term acid test. Gold also dissolves in alkaline solutions of cyanide, which are used in mining and electroplating. Gold dissolves in mercury, forming amalgam alloys, and as the gold acts simply as a solute this is not a chemical reaction.Because the processes forming ores happen on geologic time scales, the most economical mineral resources are truly nonrenewable. New deposits cannot be formed in human timescales. But, as mentioned earlier, if the reserves of materials become depleted, it is probable to find other sources that are more expensive to exploit. Moreover, mineral resources are not equally distributed.

Today’s climate challenges and fossil fuel risks affect our neighborhoods, our lifestyle, and the earth. Solar battery storage is going to be the apparent energy solution for emergencies and nighttime.

 Solar energy is one of the useful and renewable resources and does not harm the environment. Solar energy is stored using a solar panel and converted into electrical energy. The important point is whether the do solar panels work at night? Join us to find this answer.

A solar panel, or photo-voltaic (PV) module, is an assembly of photo-voltaic cells mounted in a framework for installation. Solar panels use sunlight as a source of energy to generate direct current electricity. A collection of PV modules is called a PV panel, and a system of panels is an array. Arrays of a photovoltaic system supply solar electricity to electrical equipment.

According to the facts, No! Solar panel does not generate energy at nights. Solar panels consist of photovoltaic cells that must have sunlight to produce electricity. However, that’s not the last word. Solar panels give two indirect nighttime energy answers.

Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions.

Gold is a very valuable and expensive metal that is mined. Is Gold Renewable or Nonrenewable? Join us to find the answer.

Mining companies expect the amount of gold that remains in the ground in two ways:

Reserves – gold that is economical to mine at the current gold value

Resources – gold that will probably become economic to mine after further investigation or at a costlier price level.

We can measure the number of gold reserves more accurately than resources, but this is still not a simple task.

 In this article, we will briefly introduce 4 types of gearboxes. Helical Gearbox,  Bevel Gears, Worm Gearbox, Planetary Gearbox.

Helical Gearbox 

A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called cogs), which mesh with another toothed part to transmit torque. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their gear ratio, and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Helical gears are power transmission instruments primarily utilized to reduce speed and increase torque between turning shafts. Fundamentally, they can be divided into two forms, those that transmit energy between parallel parts and those that transfer power between non-parallel components, typically introduced as cross-axis gears.

Bevel Gears

The cylindrical gear tooth profile corresponds to an involute , whereas the bevel gear tooth profile is an octoid. All traditional bevel gear generators manufacture bevel gears with an octoidal tooth profile. IMPORTANT: For 5-axis milled bevel gear sets it is important to choose the same calculation/layout as the conventional manufacturing method.

In general, we have 3 categories of Bevel Gears: one of which we will explain here.

• Bevel gears are employed in differential drives, which can transfer energy to two axles rotating at different velocities, such as those on a cornering automobile.

Worm Gearbox

A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm wheel (which is similar in appearance to a spur gear). The two elements are also called the worm screw and worm gear. The terminology is often confused by imprecise use of the term worm gear to refer to the worm, the worm wheel, or the worm drive as a unit.

For applications that need higher speed, a worm gearbox can be employed. Some of the applications of a worm gearbox are:

• Mining
• Presses
• Rolling mills
• Escalator/ Elevator Drive systems

Planetary Gearbox

An epicyclic gear train (also known as a planetary gearset) consists of two gears mounted so that the center of one gear revolves around the center of the other. A carrier connects the centers of the two gears and rotates to carry one gear, called the planet gear or planet pinion, around the other, called the sun gear or sun wheel.

The planetary gearbox got its term because of how the various gears move in a set together. We see a satellite (ring) gear, a sun (solar) gear, and two or more planet gears in a planetary gearbox. The sun-gear is normally run and thus move the planet gears bolted in the planet carrier and form the output shaft. The satellite gears have a constant location in relation to the outside components.

 In this article, we are going to talk about the gearbox. To begin with, it is better to know what a gearbox is and what it does.

The gearbox includes a power supply and a power transmission system that provide a specific application of power. The Maryam Webster Dictionary defines transmission as a set of components that include gearshift gears and bolts by which power is transmitted from the motor to an axle under load.

In the following, we will introduce and review four types of gearboxes.

Worm Gearbox

A worm gear is a gear including a shaft with a spiral section that engages with and runs a toothed wheel. Worm gears are a traditional form of gear and a sort of one of the six simple machines. Fundamentally, a worm gear is a screw butted up in front of what looks like a normal spur gear with slightly curved and angled teeth.

The most common use is in motor vehicles , where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a relatively high rotational speed, which is inappropriate for starting, stopping, and slower travel. 

What is Planetary Gearbox?

A planetary gearbox is an instrument with the output and input shafts aligned. A planetary gearbox is employed to transmit the greatest torque in the most compact form (introduced as the torque density).

An epicyclic gear train (also known as a planetary gearset) consists of two gears mounted so that the center of one gear revolves around the center of the other. A carrier connects the centers of the two gears and rotates to carry one gear, called the planet gear or planet pinion, around the other, called the sun gear or sun wheel. The planet and sun gears mesh so that their pitch circles roll without slip. A point on the pitch circle of the planet gear traces an epicycloid curve. In this simplified case, the sun gear is fixed and the planetary gear(s) roll around the sun gear.

Everything about Helical Gearbox

Helical gearboxes are one of the most widely employed gearboxes and they are more effective than any other gearbox. Their configuration facilitates many performances.

Two or more meshing gears, working in a sequence, are called a gear train or a transmission. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is that the teeth of a gear prevent slippage. 

Bevel Gear

Now you will introduce Bevel Gear and Types of Bevel Gear :

Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well.The pitch surface of bevel gears is a cone.

Bevel gears are categorized in different forms according.

In this article, we are going to introduce a gas turbine. We will also examine the Gas Turbine Cycles and its different types.

What is Gas Turbine: 

Which cycle is used for gas turbine?

The basic operation of this turbine type has roots in the gas turbine cycle which is also known as the Brayton cycle. The gas turbine cycle works like this:

Though this cycle is not ideal for open circle gas turbines, it’s still used for them with a small change in the steps. They are perfect for the closed-cycle gas turbine. This cycle contains four steps:

A gas turbine, also called a combustion turbine, is a type of continuous and internal combustion engine. The main elements common to all gas turbine engines are:

an upstream rotating gas compressor

a combustor

a downstream turbine on the same shaft as the compressor.

The first gas turbine type was turbojet engines. Although they look entirely different from reciprocal engines, they operate on the same principle: intake, compression, power and exhaust. In this type of engine, air is moved at a high speed to the fuel inlet and ignitor of the combustion chamber. The turbine induces accelerated exhaust gases by expanding air Click here to read more about different types of gas turbine.

Each year there are many death reports caused by respiratory and lung disease which are estimated that their main reason is previous lung exposures at works. knowing that their lungs are at risk in worksites, some workers and staff don’t pay enough attention to protections. the main reason why workers are sometimes indifferent to the health of their lungs in the workplace is that the hazard of respiratory disease is not often visible to see and consequences may not be apparent immediately. Sometimes symptoms take years to be revealed. There are a couple of things that employers can do to protect their workers’ lungs against airborne particles produced in the work environment. These particles can seriously affect workers’ health. One of the most easy-to-do solutions to protect workers’ lungs from exposure to harmful dust and fumes in the workplace is wearing disposable respirators or disposable masks.

Disposable Masks

One of the most frequent usages of disposable masks is in industries and different workplaces. Disposable respirators are masks mostly designed cup-shaped to be worn over nose and mouth. These masks are held on the face by straps running behind the head. Wearing disposable masks can prevent harmful substances produced from any working activity, from entering the lungs. By wearing these masks, workers, and staff greatly protect their lungs from possible damages. Good to know that most of these masks will only provide a certain level of protection, and protect against only some potential respiratory dangers. There are many different types of industrial masks and the most considerable thing one should think of is the protection level of the mask.

During the COVID-19 pandemic, face masks have been employed as a public and personal health control measure against the spread of SARS-CoV-2. Their use is intended as personal protection to prevent infection and as source control to limit transmission of the virus in a community or healthcare setting. The use of masks has received varying recommendations from different public health agencies and governments. The World Health Organization and other public health organisations agree that masks can limit the spread of respiratory viral diseases such as COVID-19. However, the topic has been a subject of debate, with some public health agencies and governments initially disagreeing on a protocol for wearing face masks.

Choosing an industrial mask mostly depends on the element and substances may be present in the air of the working environment. Some provide a limited level of protection while others may protect lungs from most of the threatening hazards. Now that we have to live in a world infected with the Coronavirus COVID-19, wearing masks can be like achieving two aims with one action which covers a recommendation and a world obligation.

Energy efficiency can be improved even more in central heating systems by introducing zoned heating. This allows a more granular application of heat, similar to non-central heating systems. Zones are controlled by multiple thermostats. In water heating systems the thermostats control zone valves, and in forced air systems they control zone dampers inside the vents which selectively block the flow of air. In this case, the control system is very critical to maintaining a proper temperature.

HVAC maintenance is an indispensable part of owning an HVAC system. Well, these systems are composed of multiple mechanical and electrical components as well as the means to connect these components to each other in order to create the system, and therefore, it is clear that maintenance would be crucial for them to keep their performance at desired levels, as well as lowering heating and cooling repair or retrofit costs.

All modern air conditioning systems, even small window package units, are equipped with internal air filters. These are generally of a lightweight gauze-like material, and must be replaced or washed as conditions warrant. For example, a building in a high dust environment, or a home with furry pets, will need to have the filters changed more often than buildings without these dirt loads. Failure to replace these filters as needed will contribute to a lower heat exchange rate, resulting in wasted energy, shortened equipment life, and higher energy bills; low air flow can result in iced-over evaporator coils, which can completely stop air flow. Additionally, very dirty or plugged filters can cause overheating during a heating cycle, and can result in damage to the system or even fire.

Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics and heat transfer. 

In the past, water heating was more efficient for heating buildings and was the standard in the United States. Today, forced air systems can double for air conditioning and are more popular.

Some benefits of forced air systems, which are now widely used in churches, schools and high-end residences, are

• Better air conditioning effects
• Energy savings of up to 15-20%
• Even conditioning

In general, heating and cooling repair costs range between $150 to $450 on average. The heating and cooling repair cost is mostly on the AC service and then on the furnace service. Diagnostic tests could cost about $80 to $100. The average cost for AC service is about $320, and $270 for furnace services. Should your system require any tune-ups, they could cost between $80 to $120.

In order to avoid replacement and heating and cooling repair costs for the components of the HVAC system, some preventive precautions could be taken. This would help save money for the users of the HVAC system, keep the system’s reliability at desired levels, and also provide high quality air and comfort for the system users consistently.

• Lithium Solar Batteries

This item is among the best solar batteries available. Lithium Solar Batteries are a great option with a really low maintenance need and they can cycle almost all of their rated capacity. That’s why they’re great intermittent and full-time use in demanding solar storage applications.

Storage for the home

One of the Bosch products to be seen at the worlds leading exhibition for the solar industry and its partners is Bosch Power Tecs BPT-S 5 Hybrid. The size of a refrigerator, this electricity storage system is suited to home use, storing the electricity a photovoltaic system generates during the day so that a family can draw it down when the sun is not shining any longer. The BPT-S 5 Hybrid is available with a basic storage capacity of 4.4 kWh, which can be expanded as required in modular steps of 2.2 kWh up to a maximum of 13.2 kWh. The BPT-S 5 Hybrid is the worlds only PV storage system to have received security certification for all components of the system from an independent institute. This satisfies the highest international safety standards. Bosch Power Tec has already amassed 200,000 hours of experience with its electricity storage systems.

A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Individual solar cell devices are often the electical building blocks of photovoltaic modules, known colloquially as solar panels. The common single junction silicon solar cell can produce a maximum open-circuit voltage of approximately 0.5 to 0.6 volts.

• Solar Power Battery Bank

The second item is the Solar Power Battery Bank. It is cost-effective and can withstand low temperatures. Just like Lithium Solar Batteries, this type also has very low maintenance needs. But keep in mind that they are not suitable for applications that require frequent cycling since they store less energy. Don’t forget that they should be stores in a ventilated and dry place and away from any heat sources.
