Inflatable latex rubber balloon, (the most common balloon) was Michael Faraday in 1824, via experiments with air and various gases. Inflatable castles and similar structures are temporary inflatable buildings and structures that are rented for functions, school and church festivals and village fetes and used for recreational purposes, mainly used by children. The growth in popularity of moonwalks has led to an inflatable rental industry which includes inflatable slides, obstacle courses, games, and more. Inflatables are ideal for portable amusements because they are easy to transport and store. The name given to such structures varies. They have been marketed with such
Solar balloon a little over 6 seconds. Below is the energy balance equation of the rate of energy lost of a solar balloon when drawing the boundary line around the balloon. The Solar Balloon experiences heat transfer due to convection and heat transfer due to radiation. Ėout= tσπr(TS4-TF4) + hπr(TS-TF) Tds=du+PdV Δs = ∫(cv/T)dT + Rgasln(V2/V1) Δs = cvln(T2/T1) The system is in equilibrium when the energy lost from the balloon through convection, radiation and conduction, equals the energy received through radiation from the sun. In 1972, Dominic Michaelis, a British architect and the inventor of many solar utilities and projects, invented
