Jeff Lee’s 2013 talk Singularity Propulsion: The Acceleration Curves of a Schwarzschild Kugelblitz Starship

The petawatt Hawking radiation of γ-ray laser-created subatomic black holes (Schwarzschild Kugelblitzes or SKs) has been proposed as a propulsive and power source for interstellar starships. In order to avoid underestimates of a SK’s Hawking power by approximately 3 orders of magnitude and overestimates of its life expectancy by 2-3 orders of magnitude (which occur when assuming purely photonic emission), this paper accounts for the entire instantaneous Hawking spectrum. Additionally shown is that 45% of the Hawking power and 55-58% of the Hawking flux are emitted on inaccessible channels. Based on the accessible Hawking spectrum, the acceleration curves of a SK-powered starship, in which the Hawking radiation is incident upon a fully-absorbing inertial plate, are determined.

Femtotechnologies and Revolutionary Projects By Alexander Bolonkin has analysis of micro blackhole drive.

Production of a black hole requires concentration of mass or energy within the corresponding Schwarzschild radius. In familiar three-dimensional gravity, the minimum such energy is 10^19 GeV, which would have to be condensed into a region of approximate size 10^-33 cm. This is far beyond the limits of any current technology; the Large hadron collider (LHC) has a design energy of 14 TeV. This is also beyond the range of known collisions of cosmic rays with Earth’s atmosphere, which reach center of mass energies in the range of hundreds of TeV. It is estimated that to collide two particles to within a distance of a Planck length with currently achievable magnetic field strengths would require a ring accelerator about 1000 light years in diameter to keep the particles on track.

Simplified explanation of MBH (microblackhole) radiation and work of AB-generator.

As known, the vacuum continuously produces, virtual pairs of particles and antiparticles, in particular, photons and anti-photons. In conventional space they exist only for a very short time, then annihilate and return back to nothingness. The MBH (microblackhole) event horizon, having very strong super-gravity, allows separation of the particles and anti particles, in particular, photons and anti-photons. Part of the antiphotons move into the MBH and annihilate with photons decreasing the mass of the MBH and return back a borrow energy to vacuum. The free photons leave from the MBH neighborhood as Hawking radiation. That way the MBH converts any
conventional matter to Hawking radiation which may be converted to heat or electric energy by the ABGenerator.

This AB-Generator utilizes the produced Hawking radiation and injects the matter into the MBH while maintaining the MBH in stable suspended state.
