Biofuels are fuels, which are chemically similar to gasoline and diesel, but are produced by processing crops, algae or microbial culture. The carbon in biofuels comes from carbon dioxide that plants convert to their biomass through photosynthesis. Biofuels are regarded as promising alternative to satisfy growing energy demands. Biomass …

The increasing energy demands to support continued (and sustainable) global economic growth, thrust for renewable power because of environmental/climate concerns, has inspired researchers to look for fundamentally new energy technologies. Space-based solar power (SBSP, SSP) is the concept of collecting solar power in outer space by solar power satellites (SPS) …

3D printing or additive manufacturing is ongoing revolution in manufacturing with its potential to fabricate any complex object and is being utilized from aerospace components to human organs, textiles, metals, buildings and even food. Additive manufacturing is defined by ASTM International as the process of joining materials together, layer by …
Read More »Electromagnetic propulsion (EMP) is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields. The term electromagnetic propulsion (EMP) can be described by its individual components: electromagnetic – using electricity to create a magnetic field, and propulsion – the process of propelling something. …
Read More »A big push has been to increase the efficiency of aircraft engines, mainly to make them go faster, to fly higher and use less fuel. Now a new concern has come to the fore, that of environment. We have to use as little fuel as possible, create as little …

High-altitude platforms (HAPs) are aircraft, usually unmanned airships or airplanes positioned above 20 km, in the stratosphere, in order to compose a telecommunications network or perform remote sensing. Aerospace companies have been trying for years to create a solar-powered plane that can fly at high altitudes for years at a …
Read More »There are three major launch types for spacecraft: vertical takeoff, horizontal takeoff, and air launch. The cost of launching into space is often measured by the change in velocity required to reach the destination orbit, known as delta-v or Δv. The amount of Δv required for a mission depends on …
Read More »A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.0 miles per gallon and drives around 11,500 miles per year. Every gallon of gasoline burned creates about 8,887 grams …
Read More »In the history of spaceflight, almost all spacecraft have been manufactured and assembled on the ground, then integrated into a launch vehicle for delivery into orbit. This approach imposes significant limitations on the size, volume, and design of payloads that can be accommodated within the fairing of a single launch …
