After yesterday's ACTIVATION, 
Shield Generator 8
Shield Generator generated a shield around your depots, which makes stealing of resources impossible. Attacking ships is still possible and ships might thus also be destroyed. But the attacker will be unable to steal your resources. Before activation however, you first need to charge the Shield Generator, which takes time. While active, the Shield Generator will consume 10% of your resource production. With higher levels, the duration of the activation period will increase. However, the charge time will increase as well. Generally, due to charge times, you can protect your planet by max 50% of the time with a Shield Generator.
Protection current level: 19:12:00
Protection next level: 21:35:59

While the Shield Generator is being charged, production is curtailed. The production rate of all your mines are reduced by 10% during charging.
