Kinetic energy recovery for buses

Anyone who has watched formula one racing and experience a bus journey will appreciate the similarities, as buses repeatedly accelerate and decelerate for bus stops and junctions in the same way as the formula one car is repeatedly changing acceleration to allow it to be steered around corners. A kinetic energy recovery system (KERS) usually [...]

How much is 1 tonne of carbon dioxide

I have a problem visualising 1 tonne of carbon dioxide. Firstly it is colourless, secondly it is usually a gas. So what sort of volume are we talking about? Relative Molecular weight = 12 + 16 + 16 = 32 + 12 = 44 g / mol. 1 tonne of CO2 = 1000 × 1000 [...]

Boeing 787 Dreamliner Launch

The Boeing Dreamliner was launched for the first test flight yesterday. The Boeing 787 is around the same size as 767-300. However the 787 is planned to be 20% more fuel-efficient than the 767. The efficiency comes equally from improvements in the engines, aerodynamics and reduced weight by use of composite materials, and the use [...]

Saving Energy

If we all make a small saving it will make a large difference. No, that will make a small difference Small changes could only make large changes is we thought that Chaos theory could be applied. In that case “making a small saving may make a large difference” could have been used. For a more [...]
