Air turborocket – Types

Turborocket A turborocket is a type of aircraft engine combining elements of a jet engine and a rocket. It typically comprises a multi-stage fan driven by a turbine, which is driven by the hot gases exhausting from a series of small rocket-like motors mounted around the turbine inlet. The turbine exhaust gases mix with the [...]

Climate change mitigation – Methods and means

] At the core of most proposals is the reduction of greenhouse gas emissions through reducing energy waste and switching to cleaner energy sources. Frequently discussed energy conservation methods include increasing the fuel efficiency of vehicles (often through hybrid, plug-in hybrid, and electric cars and improving conventional automobiles), individual-lifestyle changes and changing business practices. Newly [...]

Candle – Introduction

candle is a solid block of fuel (commonly wax) and an embedded wick, which is lit to provide light, and sometimes heat. Today, most candles are made from paraffin. Candles can also be made from beeswax, soy and other plant waxes, and tallow (a by-product of beef-fat rendering). Gel candles are made from a mixture [...]

Hybrid vehicle – Power

Power sources for hybrid vehicles include: *On-board or out-board rechargeable energy storage system (RESS) *Petrol or Diesel fuel *Hydrogen *Compressed air *Liquid nitrogen *Human powered e.g. pedaling or rowing *Wind *Electricity *Compressed or liquefied natural gas *Solar *Waste heat from internal combustion engine. *Coal, wood or other solid combustibles *Electromagnetic fields, Radio waves Adapted from [...]

Hydrogen tank – Introduction

Hydrogen tank (other names- cartridge or canister) is used for hydrogen storage. The first type IV hydrogen tanks for compressed hydrogen at 700 Bar (10000 PSI) were demonstrated in 2001, the first fuel cell vehicles on the road with type IV tanks are the Toyota FCHV, Mercedes-Benz F-Cell and the HydroGen4. At the hydrogen station [...]

Fuel efficiency – Transportation

Fuel efficiency in transportation Vehicle efficiency and transportation pollution Fuel efficiency directly affects emissions causing pollution by affecting the amount of fuel used. However, it also depends on the fuel source used to drive the vehicle concerned. Cars can, for example, run on a number of fuel types other than gasoline, such as natural gas, [...]

Hybrid electric vehicle – Technology

The varieties of hybrid electric designs can be differentiated by the structure of the hybrid vehicle drivetrain, the fuel type, and the mode of operation. In 2007, several automobile manufacturers announced that future vehicles will use aspects of hybrid electric technology to reduce fuel consumption without the use of the hybrid drivetrain. Regenerative braking can [...]

Gasification – Introduction

Gasification is a process that converts carbonaceous materials, such as coal, petroleum, biofuel, or biomass, into carbon monoxide and hydrogen by reacting the raw material, such as house waste, or compost at high temperatures with a controlled amount of oxygen and/or steam. The resulting gas mixture is called synthesis gas or syngas and is itself [...]

Musudan (missile) – Development

In the mid-1990s, after the collapse of the Soviet Union, North Korea invited the Makeyev Design Bureau’s ballistic missile designers and engineers to develop this missile, based on the R-27 Zyb. It was decided that, as the Korean People’s Army’s MAZ-543 Transporter erector launcher could carry 20 tonnes, and the R-27 Zyb was only 14.2 [...]

Samuel Brown (engineer) – Brown’s Gas Vacuum Engine

In patents dated 4 December 1823 and 22 April 1826,, Brown proposed to fill a closed chamber with a gas flame, and so expel the air; then he condensed the flame by injecting water, and operated an air engine by exhausting into the partial vacuum so obtained. The idea was evidently suggested by James Watt’s [...]
