COVER LETTER
The article “Planetary Economic Strategy for a sustainable development on the Earth”, author
Prof. Roberto Visentin, presents an original economic strategy which allows to reduce the cost of
planetary energetic investment up to 65% of its foressen value. The study, presented in the
forementioned article, makes reference to the necessary investments to link the planetary
development of the next near future to the consumptions of new energetic fuels which have to
substitute the derived fossil fuels. The consumption intensity of these fuels contributes to the
atmosphere global warming and it is cause of the exhaustion of their reserves in a time period
around a century. On this frame the Nobel prize in Economy 2015, has been alloted to Prof. Angus
Deaton (Princeton University, USA) for his studies on “consumptions in a poor world”. A diffuse
perception of the next near future problems causes the instability of the stock exchange markets, in
addition the global effort to increase the consumptions of goods and services by a planet population
which becomes poorer, while the science discovers how to lenghten the human beings life duration.
A stable transition to the Planetary Hydrogen fuel economy (Hydrogen is the main candidate to
subsitute the fossil derived fuels), foresees a world investment around 500000 billion USD, which
have to be spent in 125-150 years time period, that is 3333-4000 billion USD / Year, which reduce
1166-1400 billion USD / Year when the Planetary economic strategy (described in the article) is
adopted. If the number of taxable subjects on the planet will be 5 billion persons the added min tax
to be payed is 666-800 USD / Year per person, which is reduced to 232-280 USD / Year per
person when the forementioned Planetary economic strategy is operative. In the years 1972-80,
at the MIT, Boston, USA, has been produced the document “The limits of development” in which
are evaluated the socio economic effect of energetic fuel shortage (2030-2050), as well as of not
sufficient mais production from cultivated lands to feed 10 billion persons living on the planet (now
7 billion).
These are some of the arguments in favour of the publication on Nature of the article “Planetary
Economic Strategy for a sustainable development on the Earth”, author Prof. Roberto Visentin.
Yours sincerely,

Prof. Roberto Visentin
