(University of Manchester) Scientists from the University of Manchester are working on how to use the energy of the Sun to make fuels, which could help to solve the world’s escalating energy crisis.

Leonardo probably drew this model of a war machine for a presentation to Ludovico il Moro, “The Moor”, Duke of Milan, around 1485. The drawing in the original manuscript therefore appears neat and well laid-out.

Leonardo’s armoured car contained many light cannons. These were arranged on a circular platform which was based on four wheels and provided a firing range of 360 degrees. The whole platform was surrounded by a conical cover with a sighting turret at the top. At the centre of the car, two cranks were used to set the machine in motion.

Many consider this armoured car as the precursor to the modern tank.
