What are Electrochemical Cells?

Many electronic devices used by humans are powered by batteries that generate electricity from chemical reactions. These devices that convert chemical energy into electrical energy are commonly referred to as Electrochemical Cell. An example of such a cell is the common AA battery.

Electrochemical cells that generate electricity from spontaneous redox reactions are known as Voltaic cells or Galvanic cells (named after the Italian physicists Alessandro Volta and Luigi Galvani respectively). They are generally made up of two different metals that are connected by a salt bridge. Electrolytic cells are the electrochemical cells that consume electrical energy in order to drive a redox reaction that is not spontaneous.

Electrochemical cells can be broadly classified into two categories – primary cells and secondary cells.

Primary Cells

Primary cells are the electrochemical cells that generate electrical energy from irreversible reactions. These cells cannot be recharged once the reactants are completely consumed, and must be discarded when depleted. Common examples of primary cells include use-and-throw galvanic batteries.

Secondary Cells

The electrochemical cells in which the cell reaction is reversible are commonly referred to as secondary cells. These cells can be run as both electrolytic cells and galvanic cells. They are also known as rechargeable batteries.

Most electrochemical cells consist of two half-cells, which are made up of an electrode dipped in an electrolyte. These half-cells are generally connected by a salt bridge, which provides a platform for ionic contact. Oxidation occurs in one half of the cell whereas reduction occurs in the other. Once chemical equilibrium is reached, the net voltage of the electrochemical cell reaches zero and the production of electricity is halted.

Cannabis and H-2A Guest Worker Program

Cannabis is a plant that has caused mass hysteria for an extended period. Canada legalized marijuana across the board in 2018, and the United States will hopefully do the same shortly. The economic benefits are evident and needed in an economy that many people believe is trending toward another recession. While this industry continues to grow, many citizens remain hesitant to partake in the consumption or business of cannabis. With this said, countless individuals are looking to move to the United States from other countries. Cannabis farmers can use the h2a guest worker program to help these businesses grow.

Setting a Precedent

There are some Americans that believe foreigners are taking jobs in this country and are a detriment to the economy. Whether this is true or not, foreigners are willing to perform job functions that many citizens are not willing to do. Since the agricultural industry is not receiving much attention concerning job prospects, H-2A guest worker programs are necessary. As the demand for cannabis increases, cannabis companies can bring agriculture back into the limelight. These are by no means the most appealing positions on paper, but the amount of value they provide cannot be understated.

Starting Mass Legalization

The stigma attached to cannabis is questionable on many grounds. However, once proper research reaches the public eye, this should change. Aside from the potential medicinal benefits, potential profits in this industry are staggering. Since cannabis is a commodity, it will be highly sought after once it becomes legal countrywide. Start-up costs for any business are steep, and this certainly pertains to labor also. Cannabis companies looking to capitalize on early adopters may be able to create a profitable business by using H-2A guest worker programs. Managing crops is a difficult task, but someone needs to do it for this industry to thrive soon.
