Scientific research has shown that infusing salt onto hydrophobic filter media successfully inhibits microbial growth on various surfaces. The experiment in this article aims to test such a theory by treating several types of fabrics with salt-based solutions to inhibit bacterial growth from a simulated potential droplet infection. In the spirit of collaboration with the global fight against COVID-19, a team of researchers, composed by Marcos Lopez, Corinna Nielson, and Roberto Baldizon partnered with Hospital Privado de Peten in Guatemala to carry out these tests to ignite their vision of positive social impact for low-income communities around the world.


The energy industry is known as one where widespread technological adoption moves rather slowly due to the high capital costs of switching current equipment, behavior, and culture. It is important to note that for a change to be impactful in the energy industry, it would have had to reach large scales compared to what an impactful breakthrough adoption would mean for other industries. Over the long term, and through cumulative observation of system deployment, disregarding of current socio-political, economic trends, the longer-term outlook for Solar plus Storage remains bullish. The reason for such optimistic forecast for the industry lies in that distributed generation products deployed in the market already provide users with energy resiliency, independence, reliability, and security, all which are becoming continuously more valuable as the effects of climate change aggravate. …

Solar power capacity has been continuously increasing in our world during the last recent decade. In fact, according to Bloomberg Business, since 2013 our society has been increasingly adding more Capacity from Renewable Energy Sources rather than from Fossil Fuel Burning Plants. In the United States mainly, Federal tax credits and financial incentives from government and utility companies have fueled an increase in the renewable energy percentage share of the energy mix. The Solar Energy Industry Association reports that since 2013 solar has had a larger share than wind and coal in new generating capacity.

Although solar has had golden years, as the Tripleundit website states, to maintain the increasing value of solar energy work will have to be done by the government, and industry. The US government will have to reevaluate the benefits from solar energy and introduce a new incentive after the Solar Tax Credit comes to an end. Similarly, utility companies will have to readjust their business models to individuals with excess solar capacity in their roofs. The solar industry will need to keep up with research to gain higher profitability in an era where natural gas resources have become so abundant. …

Oil & Gas logistics are a significant economic driver for many areas of our world, producing jobs, businesses, and profits for small, medium, and large corporations. Both of these resources are essential for our modern way of life, thus understanding their commercialization and production process is vital for professionals in this and related fields. In this article, we will examine how each section of the supply chain impacts positively our global economy.

Soteris Kalogirou describes fully how to desalinate water using common materials and sunlight in his book “Solar Desalination Systems for Solar Energy Engineering.” To automize the quantifiable nature of the problem we will use Scilab (Matlab’s open language and environment twin) in this article to simplify the problem and solve it quite quickly. The code will be included below and can be replicated by anyone which would like to give it a try and experiment with it in the real world to give people in dry places access to fresh water.

All industries need to be regulated to ensure public safety and maintain confidence in products and processes. As Cari Williamette describes in her Solarpro article, there are two central industry regulators for solar, standards and codes. As she explains it, standards are legally enforceable while laws are more like recommendations. Understanding both and following at least the lawfully enforceable rules (standards) is of extreme importance for project development. Installers should maintain proper communication with the system’s local authorities with jurisdiction (AHJ) to avoid misunderstandings. Companies that have no adequate dialogue with authorities get into possible projects delays that cost money. …

Pennsylvania is historically a state rich in natural resources extraction. In fact, Colonel Drake drilled the first Oil Well in the World in this state more than one hundred years ago. The economy of the commonwealth has been fueled through the ages by industries related to the extraction of natural resources such as coal, oil and recently natural gas. Not only have all these fuels increase the income of households in this state but they have also been vital in the development of global civilization.

Recent advancements in technology are allowing the state of Pennsylvania and the entire Appalachian Basin region to become a hot spot for natural resource extraction again. Devonian shales from the Basin, which have natural geological fractures have become reserves with the usage of horizontal drilling and fracking. Drilling and fracking have allowed the fractures to connect in a manner that increases permeability and allow first gas producing wells. Understanding the orientation of fractures is key for drilling companies as the direction of such can be adjusted for maximum production. Figure one shows a map with displays the extension of the Marcellus and also indicates some points that the course of the rock has been proven to be constant as predicted by Geological theory. …

This article will examine a hypothetical proposal for a possible solar project for a hotel located in Boston, Massachusetts. The city of Boston has friendly policies towards renewables for which has been named a Solar America City by NREL. Boston’s solar resource information is displayed in table 1 where we can see that it is located at one of the higher latitudes of the United States where greater weather variability through the year is expected.

Guatemala is a country with 15,000,000 people slightly smaller than the state of Pennsylvania in land area. The nation has a GDP of about 60 billion dollars, and abundant natural resources as seen in the daily solar resource map from the Global Energy Network Institute attached in figure 1 below.

Solar thermal systems are competitive in many industries, but it is in the applications related to industrial processes where it outshines other energy sources. One of the most exciting forms of solar thermal systems is in its usage for water desalination in our planet’s most arid regions. Desalination using solar systems has an edge on remote areas using smaller operations in the Middle East and North Africa, where lack of potable water poses big problems due to groundwater salinity, and scarce rainfall.

There are mainly two methods for desalination using solar thermal systems, indirect and direct. Direct systems use solar energy to produce distillate directly in the collector, while indirect systems combine with conventional desalination technologies. For indirect methods, the solar part produces heat/electricity energy that can be used in the desalination process. Direct systems are lower cost, more straightforward, but require a larger area than indirect, for which they are intended for small projects. Conventional Desalination techniques are Multistage Flash Desalination, Vapor Compression, Reverse Osmosis, Membrane Distillation, and Electrodialysis. …
