Question: How many households can be supplied with 1 megawatt of power and how large would the solar panel be?
The number of square meters of solar panels required to generate 1 megawatt (MW) of power depends on several factors, including the efficiency of the solar panels, the amount of sunlight available in the location where the solar panels are installed, and the specific technology used.
On average, solar panels have a conversion efficiency of about 15-20%, which means that for every square meter of solar panel area, you can expect to generate between 150 and 200 watts of power in direct sunlight.
So, to generate 1 MW of power, you would need between 5,000 and 6,667 square meters of solar panels (assuming an average efficiency of 17.5%).
There are 2.58999 square meters in one square mile.
To convert 6,667 square meters to square miles, we can divide 6,667 by 2,589.99:
6,667 sq meters / 2,589.99 sq meters/sq mile = 2.572 square miles (rounded to three decimal places).
Answer: Therefore 2.572 square miles of solar panels are required to supply 9345 household of power for 1 hour.
The number of households that can be supplied by 1 megawatt of power depends on a variety of factors, including the amount of electricity each household consumes, the time of day, and the season.
However, as a rough estimate, the US Energy Information Administration (EIA) reports that in 2020, the average US household consumed about 9,369 kilowatt-hours (kWh) of electricity per year, which is equivalent to an average of 0.107 MW of power.
Based on this average, 1 MW of power could supply approximately 9,345 households (1,000,000 watts / 0.107 MW per household) with electricity for one hour, assuming that all households are consuming the average amount of electricity.
Again, this is a rough estimate, and the actual number of households that can be supplied by 1 MW will depend on various factors such as the region, the time of day, and the actual energy consumption of each household.
Discussion: A typical residential lot is one-half acre. Rounding 9345 households to 10,000 households; the households themselves have a footprint of 7.8125 square miles; with 1/3rd of the 2.572 square miles for 1 megawatt taken up by the panels.

Duncan Stroik Architect
“The ideal architect should be a man of letters, a skillful draftsman, a mathematician,
familiar with historical studies, a diligent student of philosophy, acquainted with music,
not ignorant of medicine, learned in the responses of jurisconsults,
familiar with astronomy and astronomical calculations.”
Duncan G. Stroik is a practicing architect, author, and Professor of Architecture at the University of Notre Dame specializing in religious and classical architecture. Gathered here are images from Christ Chapel, Hillsdale College Michigan. His award-winning work includes the Our Lady of the Most Holy Trinity Chapel in Santa Paula, California, the Shrine of Our Lady of Guadalupe in LaCrosse, Wisconsin, and the Cathedral of Saint Joseph in Sioux Falls, South Dakota.
A frequent lecturer on sacred architecture and the classical tradition, Stroik authored The Church Building as a Sacred Place: Beauty, Transcendence and the Eternal and is the founding editor of Sacred Architecture Journal. He is a graduate of the University of Virginia and the Yale University School of Architecture. Professor Stroik is the 2016 winner of the Arthur Ross Award for Architecture. In 2019, he was appointed to the U.S. Commission of Fine Arts.

Can Voters Detect Malicious Manipulation of Ballot Marking Devices?
Can Voters Detect Malicious Manipulation of Ballot Marking Devices?
Matthew Bernhard, et. al
University of Michigan
Abstract: Ballot marking devices (BMDs) allow voters to select candidates on a computer kiosk, which prints a paper ballot that the voter can review before inserting it into a scanner to be tabulated. Unlike paperless voting machines, BMDs provide voters an opportunity to verify an auditable physical record of their choices, and a growing number of U.S. jurisdictions are adopting them for all voters. However, the security of BMDs depends on how reliably voters notice and correct any adversarially induced errors on their printed ballots. In order to measure voters’ error detection abilities, we conducted a large study (N = 241) in a realistic polling place setting using real voting machines that we modified to introduce an error into each printout. Without intervention, only 40% of participants reviewed their printed ballots at all, and only 6.6% told a poll worker something was wrong. We also find that carefully designed interventions can improve verification performance. Verbally instructing voters to review the printouts and providing a written slate of candidates for whom to vote both significantly increased review and reporting rates-although the improvements may not be large enough to provide strong security in close elections, especially when BMDs are used by all voters. Based on these findings, we make several evidence-based recommendations to help better defend BMD-based elections.
