A plan involving the use of 4,500 service drivers and 1,650 tipper lorries was considered capable of moving 100 kilotonnes a day of coal to the power stations.
In 2006 it produced 826 kilotonnes of CO2.
But wouldn't earth-penetrating weapons with much lower yields (under five kilotonnes) be even better, since their lower yield would surely make them politically more acceptable to use?A dangerous detourLow yield is not no yield.
Its break-up released 500 kilotonnes of energy, equivalent to the yield of a large nuclear bomb, blowing out windows and injuring more than 1,000 people.
Such coverage is essential to deter cheats if possible and to detect them if necessary, since below five kilotonnes of explosive yield it becomes hard to tell a nuclear test from an earthquake, and below one kilotonne a test might be taken for a large chemical explosion.
The missing mass - equivalent to that of three suns, or six trillion trillion kilotonnes - was converted into energy and released as the gravitational waves LIGO is believed to have detected.
This bomb had an explosive energy of 16 kilotonnes of TNT, it killed an estimated 90,000 166,000 people and destroyed roughly 50,000 buildings.
To date, while NetJets argues that "it is impossible to achieve zero emissions in the short term," it has capped greenhouse gas emissions (down from 234 kilotonnes of CO2 equivalent in 2009 to 229 kilotonnes in 2011), with aircraft operations accounting for 95% of the firm's overall emissions.
Bob Cywinski, of the University of Huddersfield, said: "One tonne of thorium is equivalent to 200 tonnes of uranium and it doesn't need processing or enriching – 57 kilotonnes of thorium would provide the total energy need of the planet for a year, not just electricity but transport".
These harrowing exhibits are among the few physical reminders of the devastation that greeted survivors after the US B-29 bomber Enola Gay released Little Boy, a 16-kilotonne atomic bomb, over Hiroshima at 8.15am on 6 August 1945.
Anti-fracking campaigner Will Cottrell, chairman of the Brighton Energy Co-operative, claimed a 10-well fracking facility was "like setting off a 4.4 kilotonne nuclear bomb".
