Patent Attorney Office River-Vu

Patent Lawyer View

My law firm, Young & Thompson, moved into nice new offices at the northern edge of Old Town Alexandria, Virginia. Somehow I was given a prestigious (but not corner) office with a view of the Potomac river.

Although you can barely see it, the Alexandria boathouse is at the end of Madison street, and one can see the rowing team practice in the late afternoon.

AACHEN GEOTHERMAL ENERGY

The Goozner Solar Review arises from my long standing interest in all forms of alternative energy. This not only includes solar energy, but all kinds of energy that are non-carbon based. Above, you see me in front of the geothermal project at the University of Aachen (Germany). The geothermal energy is obtained by sinking a shaft about 1km straight into the ground, and exploiting the temperature gradient between the abyss and the surface. This shaft will supply most of the energy used by the University.
