Analyzing the Impact of Bapco 5 MW Solar PV Grid-Connected Project on Bahrain’s Outlook for Energy-Mix Production

The impact of Bapco 5 MW solar PV grid-connected project on Bahrain’s outlook for clean energy and energy-mix production was analyzed since solar electricity obtained from PV installation is considered as a non-linear system. Several positive impacts were counted. These impacts were on business, economy, environment, research, green jobs creation and rooftop installation and other large-scale installation. This project had attracted public, investors, developers to invest in similar projects in the Kingdom of Bahrain;especially it is an environmentally friendly and smart technology. This innovative smart grid-connected 5 MW solar PV power plant is enough to electrify 500 houses @ 10 kW and had answered lots of frustrating questions such as the effect of dust on PV performance, need of man-made cleaning compared to naturally cleaned PV panels, reliability of the system, greenhouse gases reduction and pay-back period.

There has been some extensive research investigating the effect of Far Ultraviolet Radiation (UVC) on SARS and MARS. However, to the best of our knowledge, there have not been any detailed experiments looking at the effect of UVC on COVID-19 (now is called SARS-CoV2). Many researchers in this field believe that UVC destroys SARS-CoV2 because it warps the genetic material of the virus hurdling the viral particles from reproduction. In this paper, we report the result of our novel experiments on the effect of UVC on SARS-CoV2 using a commercially available UVC source, i.e. Krypton Disinfection lighting CM15W12V Series (wavelength of 222 nm), which is sold and marketed for the disinfection of pathogens. The experiments were extended to study the effect of UVC exposure to Bacteria and Fungus. Our experiments show that UVC has no effects on SARS-CoV2 when it is close to the SARS-CoV2 culture plate (4 - 5 cm) or at a distance (2.0 to 2.9 m), i.e. when fixed at the ceiling. This observation is important as the public seems to have the impression that commercial UVC ceiling light can kill SARS-CoV2 while this study has proven the opposite. Moreover, it shows no effect even when the UVC ceiling light is radiating on SARS-CoV2 for overnight. This proves that the intensity of the UVC from these devices is relatively low. However, the UVC light is found to be effective in destroying Bacteria and Fungus (part of pathogens), substantially, in 30 sec, and completely kills them when it’s at 2.9 m (or less) away from them and exposure for one day. This indicates that the UVC light is effective for bacteria disinfection.

Worrying about Climate Change

It is becoming clear that Climate Change is getting severe. It was reported that the improved ocean heat measurements have a rate of warming upwards from 4 to 5 Hiroshima bombs liberated heat per second or 388,800 per day. It was reported also that our climate has accumulated the equivalent of a total of more than 2.8 billion Hiroshima bombs’ worth of heat since 1998. Despite this global concern about the effect of global change on environment, it is believed that the problem is much more severe and with greater impact on all facets of life. The effect of Climate Change, especially with a 1℃increase in global temperature (from 14℃to 15℃) is equivalent to the heat liberated from explosion of about 300 million Hiroshima of atomic bomb. This is why this CoP 26 becomes more serious and had targeted year 2060 as a year of zero CO2 emission. This paper discusses the impact of climate change on ten sectors;water, water desalination, energy, renewable energy supply, health, society, agriculture, economy, industry, and built environment.

Do UV LED Devices Immolate SARS-CoV2?

Health 2020年第11期12卷 1445-1456页

Some manufactures made UVC LED Strip as disinfection tool against SARS-CoV2. Therefore, three types of commercially UVC lights were used to evaluate their efficiency to warp bacteria and viruses. We tested three commercially available UV lights devices. They were put at 4 to 5 cm to spiked sterile Petri dishes (samples) for 10, 20, 30, and 60 seconds and compared it to control (without UV light exposure). Also, the same three UV LED devices were used on Positive SARS-CoV2 swab samples (used for the Petri dishes). Serial dilutions of the cultured microbes were used for the experiment as follows: 1/10 (high concertation), 1/100, 1/1000, 1/10,000, 1/100,000 (low concertation). All three UV LED devices (DA, DB, DC) were found to have no effects on the pathogens (Bacteria or SARS-CoV2), even to the lowest Bacteria Concentration (1/100,000), when pathogens were exposed to UV radiation for 10, 20, 30, and 60 sec at distance a 4 to 5 cm. One of the manufacturers of these UVC lights (DB) claims that the device is very effective in killing Bacteria and Virus immediately at a 99.93% killing rate (in 20 sec.). This observation was not noticed. False claims may lead to severe spread of SARS-CoV2 as customers may think that the DB was disinfecting, after short exposure, while truly having no effect.
