A. Element in microcomputer chip.
Students are invited to find the 31 words/expressions, associated with
carbon capture and storage, hidden in this grid contributed by Bert
Neary. Words read in any direction, but are always in a straight line.
Some letters may be used more than once.
When all the words are found, the unused letters, when read in order,
will spell a further 8-letter word. Please send your answers to the editor
at the usual address to arrive no later than Monday 23 May. First correct
answer out of the editor’s hat will receive a £25 Amazon gift voucher.
