Those clever people at Futurelab, the learning technology charity, think long and hard about how our schools should look in 2025.
Amid the rush of headteachers keen to buy new computer technology, a report commissioned by Futurelab points out that schools already have access to their own big data-processing pools.
Apparently, they consist of well-engineered computers and are attractive to engineers for mundane reasons. And they are abundant in schools.
Each is compact (approximately 1,300cc), very light (about 1.4kg), runs cool (37C), uses cheap and renewable sources of energy (glucose and oxygen), and requires very little power (about 20 watts).
Yes, scientists are already trying to build biological computers, modelled on the human brain.
