Engines generated energy in short bursts (8)

I believe the answer is:

turbines

'engines' is the definition.
(turbine is a kind of engine)

'generated energy in short bursts' is the wordplay.
'generated' is an anagram indicator.
'energy' becomes 'e' (physics symbol as in E=mc2).
'short' means to remove the last letter.
'bursts' with its final letter taken away is 'burst'.
'e'+'in'+'burst'='einburst'
'einburst' anagrammed gives 'TURBINES'.

(Another definition for turbines that I've seen is " Machines producing power from water, steam, etc".)

I've seen this clue in The Independent.
