Israel is putting together a plan for a national investment fund that would tap an anticipated natural gas bonanza to fuel both an export-geared economy and provide a nest egg of $10 billion in under a decade for future generations. Some of the revenues would be invested in strategically critical targets such as education, health, and using some of the proceeds to endow a new set of export-oriented, technology-based industries that would build on what has traditionally been the country's greatest resource: human capital. Based on Bank of Israel and Finance Ministry assessments, the fund could be managing $10 billion by 2021, with revenues starting to accumulate by 2015.
