More Hilarious Notes From Annoyed Neighbors Page 13

Jan 20, 2021 · This is just priceless. We don't know which note is funnier (or more worrying) - the one asking tenants to use a specific type of toilet paper because the building's sewage system is so bad that it can't handle the quality kind toilet paper, or the one from a tenant asking if he can use socks instead.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Power Generation Efficiency - an overview | ScienceDirect

The first electrical power plants were very inefficient, with the thermal efficiency steadily increasing with improved equipment design. Data summarized by Haywood 1 and shown in Figure 7-4 illustrate this improvement in electrical powergeneration efficiency over the past century. In 2002, the most efficient power plants converted 53% of the energy in natural gas to electricity.

Lighting - Wikipedia

Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings.
