In the past 20 years the commercial space industry mainly through the efforts of Space X has pushed down costs to low earth orbit from $22,000 to $3,300 USD per kilogram. As reusable boosters become a reality this cost ratio is likely to dramatically improve again and for the first time bring the economics of space travel into the range of business for mining and other purposes. In the early 2000's David made his first venture into aerospace, only to find the economics of launch vehicles were not yet ready to support private space resource commercialization. With this equation finally tipping toward a new more economically attractive status, there will likely be great strides in this trend in the near to middle term.

The clothes you wear, the transportation you use, the abundant food you eat, the luxuries we all take for granted, are largely the result of the huge surplus of energy we enjoy. However as finite fossil fuels such as oil, coal and gas become ever more expensive to find, extract, and refine it is ever cheaper wind, solar and nuclear power that will serve as the growing means for us to continue maintaining our energy rich societies. Realizing this trend in the mid 2000's David developed first a biofuels company in Maryland and later a biotech company in Louisiana, and a Solar project in Hawaii in order to take advantage of this new economic reality of expensive oil and cheaper renewable energy.

In our lifetimes we can all bare witness to the unimaginable improvements in computational power, storage and bandwidth that have taken place. As Moore's Law passes its 50th year with no sign of abating, David has followed this trend closely by first investing heavily in the development of internet technology in the late 1990's & has since in the early 2010's ventured into developing machine learning, natural language processing and personal data aggregation applications that leverage these trends.
