Allowing for the mass of the interstitial air, the true density of the structure is approximately 2.1 mg/cm 3 (2.1 kg/m 3), which is only about 1.76 times the density of air itself at 25 °C. The material is described as being 100 times lighter than Styrofoam. [9] Microlattices can also be 100 times stronger than regular polymers. [10]
[2] Ultralight material also has elastic properties. Some ultralight materials are designed with more pores to allow the structure to have better heat transfer, which is needed for many materials, like pipes for example. [3] [1] In compression experiments, ultralight materials almost always show complete recovery from strains exceeding 50%.
The car and rocket are products of Tesla and SpaceX, respectively, both companies headed by Elon Musk. [5] The 2010 Roadster is personally owned by and previously used by Musk for commuting to work. [2] It is the first production car launched into space.
Stuff Matters: Exploring the Marvelous Materials That Shape Our Man-Made World is a 2014 non-fiction book by the British materials scientist Mark Miodownik. The book explores many of the common materials people encounter during their daily lives and seeks to explain the science behind them in an accessible manner.
An aerogel material can range from 50% to 99.98% air by volume, but in practice most aerogels exhibit somewhere between 90 and 99.8% porosity. [12] Aerogels have a porous solid network that contains air pockets, with the air pockets taking up the majority of space within the material. [13]
Significantly, the Scout was the first ultralight aircraft to be covered by airworthiness regulations in the world, in this case-Australia's Air Navigation Order(ANO)95.10 issued by the Department of Transport. In 1975 Ron Wheeler approached The Department of Transport to issue an Air Navigation Order regulation for ultralight and minimum aircraft.
The General Motors Ultralite was a 1992 low emission vehicle concept car intended to demonstrate the benefits of advanced materials and low fuel consumption.. It was rated at 88 miles per US gallon (2.7 L/100 km; 106 mpg ‑imp) by the EPA, [1] but could achieve 100 miles per US gallon (2.4 L/100 km; 120 mpg ‑imp) at a steady state cruising speed of 50 mph.

In 1946, the Fulton FA-2 Airphibian was an American-made flying car designed by Robert Edison Fulton Jr., it was an aluminum-bodied car, built with independent suspension, aircraft-sized wheels, and a six-cylinder 165 hp engine. The fabric wings were easily attached to the fuselage, converting the car into a plane.
