Sie strahlt vor Freude über ihre Auszeichnung – TH-Alumna Melanie Klaus. Für ihre Bachelorarbeit im Bereich Erneuerbare Energien wurde sie vom Solarenergieförderverein Bayern geehrt. In ihrer Bachelorarbeit im Studiengang Elektro- und Informationstechnik untersuchte sie das Zusammenspiel von Wind- und Solarenergie und den Nutzen, der sich hieraus für die regenerative Energieerzeugung erzielen lässt. Untersucht wurde also die Nutzung der natürlichen Kombination von Wind und Sonne für die Energieerzeugung. Um die Rentabilität dieser Einspeisekombination zu ermitteln, hat Melanie Klaus ein Software-Tool entwickelt, welches zur Planung und Simulation abgestimmter Photovoltaik-Wind-Kombinationen dient und bereits für die Errichtung einer Photovoltaik-Anlage zu einem Windpark eingesetzt wird. |

“…The solar panels will populate the gothic chapel roof, producing an approximate 105,000 kWh of energy a year – enough to run the chapel’s electricity, and saving around £20,000 in energy bills per year. The college confirmed that any excess energy would be sold off to the national grid.

Solar panels perform better when listening to music:
A 2013 study by researchers at Imperial College London and Queen Mary University of London showed that solar panels actually work better when exposed to music, of multiple genres. Scientists at the university proved that when exposed to high pitched sounds, like those found in rock and pop music, the solar cells’ power output increased by up to 40 percent. Classical music was also found to increase the solar cells’ energy production, but slightly less so than rock and pop, as it generally plays at a lower pitch than pop and rock. Whether they know it or not, British band Coldplay are just one of the artists benefitting from this research. During their 2021 tour, they installed solar photovoltaic panels in the build-up to each show, “behind the stage, around the stadium and where possible in the outer concourses”…

Self Reliance: Ralph Waldo Emerson
“Self-Reliance” by Ralph Waldo Emerson is an essay that emphasizes individualism, nonconformity, and the importance of trusting one’s own instincts. Here are some passages from this influential accomplishment that informs American culture:
“Trust thyself: every heart vibrates to that iron string.”
” A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines.”
“To be great is to be misunderstood.”
“Whoso would be a man must be a nonconformist.”
“Nothing can bring you peace but yourself. Nothing can bring you peace but the triumph of principles.”
These excerpts capture the essence of Emerson’s philosophy in “Self-Reliance,” promoting the idea of individualism, self-trust, and the pursuit of one’s unique path in life.
We have avoided listing interpretations offered by artificial intelligence algorithms because those algorithms are informed by at least one-hundred years of biased interpretation by scholars funded by the US federal government which has long since grown hostile to individualism; worthy coffee-house debate. We recommend you consult the original text, linked above.

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.

Gabriel Fauré’s “Cantique de Jean Racine” is a choral work composed in 1865 when Fauré was 19. Written for a four-part choir, it’s a setting of a Latin text by the 17th-century French playwright Jean Racine, which reflects a deep, devotional tone. The text is a hymn of praise and supplication, asking for divine grace and mercy.
Fauré’s composition is noted for its lyrical beauty and sophisticated harmony, showcasing his early mastery of choral writing. The piece begins with a serene, flowing melody in the sopranos, which is then developed and harmonized throughout the choir. The work features lush, rich chords and a gentle, flowing rhythm, characteristic of Fauré’s style, blending simplicity with depth. Its mood is one of quiet contemplation and reverence, aligning with the text’s themes of divine worship and reflection.
AFNOR a organisé une discussion autour du nouveau livre La Loi Ne Fait Plus le Bonheur (The Law No Longer Makes You Happy) de Françoise Bousquet et Stéphane Jock, préfacé par Alain Lambert. L’ouvrage se distingue par son caractère grand public : après une clarification du désordre sémantique autour du mot « norme », Les auteurs y présentent de manière simple, ludique et concrète les bienfaits des normes volontaires pour l’individu, l’entreprise et le pays. Ils proposent une voie nouvelle pour mettre enfin un terme à l’inflation de textes législatifs et réglementaires : développer leur complémentarité avec les normes d’application volontaire co-construites par celles et ceux qui sont concernés.
