Basic Design - Atomic Rockets

Everything about fundamental spacecraft design revolves around the Tsiolkovsky rocket equation.. Δ v = V e * ln[R]. The variables are the velocity change required by the mission (Δ v or delta-V), the propulsion system's exhaust velocity (V e), and the spacecraft's mass ratio (R).Remember the mass ratio is the spacecraft's wet mass (mass fully loaded with propellant) divided by the dry mass

Mapped: The world's coal power plants in 2019

Since 2000, the world has doubled its coal-fired power capacity to around 2,000 gigawatts (GW) after explosive growth in China and India. A further 236GW is being built and 336GW is planned. More recently, 227GW has closed due to a wave of retirements across the EU and US. Combined with a

Special Report - U.S. 'clean coal' program fails to

By Tim McLaughlin Champions of coal say the superabundant fossil fuel can be made environmentally friendlier by refining it with chemicals - a "clean coal" technology backed by a billion dollars in U.S. government tax subsidies annually. But refined coal has a dirty secret. It regularly fails to deliver on its environmental promises, as electric giant Duke Energy Corp found.
