How could you rapidly increase a black hole's mass?

Say you were using a black hole as a propulsion drive á la Crane and Westmoreland http://arxiv.org/pdf/0908.1803.pdf- so your black hole has a radius of around .9 attometers - super tiny - around 600,000 tonnes. How much energy would be required to increase its size to say 100 earth masses? And how quickly could you do it? Is there any way that much energy could be contained in a bomb or weapon? Crane and Westmoreland talk about using spherical gamma lasers to create their artificial black holes. Is there a possible solution here? We are obviously talking about advanced technology, but if it's just too absurd, I want to know.
