A pot of boiling water to steam eggs faster than boiled eggs. Because the steam temperature is high, the steam once exothermic into water, but also the second exothermic, so steaming the egg can make the egg to get more heat, so steaming faster.
Imagine if the water temperature has not reached the boiling point, such as 80 ℃, it is possible to cook the eggs, but in this case you want to steam the eggs, it should be unlikely.
