Undoubtedly, nuclear power will make a substantial contribution to

emissions of pollutants, is effective, safe and soon it will reach the bottom of the
bag on oil, coal and gas. But nuclear plants do not operate simply clean. The
risks of nuclear power include: the risk of major accidents (like Chernobyl or the
Fukushima Daiichi), leakage of radioactive substances that can damage both the
environment and human health in the area, disposal of radioactive waste
resulting from the operation, the proliferation of nuclear weapons (in reactors use

USING WASTE AS AN ALTERNATIVE ENERGY SOURCE
Urban waste in storage can be an inexhaustible source of energy.
Under the action of bacteria, an organic substance from waste undergoes
anaerobic reduction as a result the significant amount of biogas, which contains
an average of over 50 % methane, which has a high calorific value. These
gases can be captured by a network of pipes, filters, dryers can be fuel for an
internal combustion engine driving a generator, or can be liquefied. Thus from
the waste, obtain electricity, clean energy and easy to carry. In this way all
urban landfills in Romania can become energy producers. The benefits are

ELECTRIC CARS – Part I
In recent years, in all countries, urban transport pose specific
problems and produce significant damage to political, social and environmental
(pollution, noise, and stress). The best solution to problems of environmental
pollution is electric vehicle (EV) as an alternative means of transport.
Electric car is a vehicle that uses an electric motor as a drive with
electric power from a source, usually battery. The major advantages of electric
car are fuel economy, pollution near zero outside production, efficiency/high
yield, instant acceleration, very low noise, easy maintenance by eliminating
much of the classic motor car. High price and low autonomy are barriers to the
success of such vehicles. Over nearly two decades, 86 % of cars in circulation
will be powered by conventional motors. However, they have several
disadvantages. Major disadvantages are high cost, relatively high load time,
lifetime low of about 3-5 years, reduced autonomy max. 300 km. Batteries are
reducing capacity by 50 % or more at temperatures below 10 0C and above 40
0C and tend to overheat and even explode under certain conditions. In 1996,
the first serial production electric car, EV1 (Electric Vehicle 1), were
manufactured in the U.S. by General Motors, and circulated on California
roads. Although General Motors has built and launched on the market between
the years 1996-1999 the first electric car, EV1 was withdrawn and recycled to
pressure oil companies and the argument of lack of market demand.
Lithium batteries have been proposed for the first time in 70 years, but
their sale started only after 20 years. Lithium is a metallic substance such as
highly volatile and corrosive, which reacts violently with many other substances.
Corrosive properties of lithium are strongly enhanced with increasing
temperature, leading to accelerated oxidation coatings and the membranes that
separate the battery components, leading eventually to irreversible damage.
Much lighter than regular batteries, rechargeable, usually made of nickel
components with better performance and longer life Li-ion cells were deejay Li-
553
ion cells have been used for proper laptops and mobile phones. Using lithium
batteries to power electric vehicles involves ensuring some form of Li ion
batteries, many experts feel that the technology is ready for the first generation
of electric vehicles. The year 2008 is the de facto beginning of the era in allelectric
vehicle range. This year she has launched various marketing concepts
battery with a relatively high yield and affordable. Thus, it is expected that by
2010-2015 an electric car can be manufactured on a large scale performance
series at a price close to the price of petrol cars.

2010-2015 an electric car can be manufactured on a large scale performance
series at a price close to the price of petrol cars. A study by University of
California at Berkeley shows that about 86 % of cars running on the streets will
be electric in 2030. The percentage is subject to the emergence of centres of

Le travail présente les principaux types d’usures qui apparaissent aux
pompes des machines pour la protection des plantes. Pendant le
fonctionnement d’un system technique, appraising des usuriers, dues aux
frictions et aux agressions physique et/ou chimiques, usures qui modifient
géométriquement, dimensionnelle et structurale, les qualités fonctionnelles du

ECONOMICHAL EVOLUTION OF ROMANIA
Before and after EU accession, statistics show a modest position of
Romania in the EU and its lack of improvement over time, the absolute value of
GDP/capita (taken in $), the relative value of GDP/inhabitant (considered as %
of EU average) and, worse, a worsening world order number NOM, i.e. the
number of orders in the list of world states considered in descending order of
GDP/capita. The situation can be explained by statistical data on the number of
international patents for invention obtained by each country. Currently have
GDP/high only countries that have large natural resources and capitalizes

ABOUT INVENTIONS AND INVENTORS
An invention is a solution or a technical achievement in a field of
knowledge which shows the progress from the novelty stage known until then.
An invention is defined ”as a machine, a process, an improved etc.-new and
useful, which existed previously and which are recognized as the product of an
intuition or a unique genius, outstanding mechanical skills common or craft”
Henry Ford, founder of the American automotive industry; Swedish engineer
Alfred Nobel considered the inventor; American inventor Thomas Alva Edison,
the owner of the 1903 patent research, known in the whole world as the
inventor of the incandescent bulb; American engineer William BULLOCK in
1863 invention of which revolutionized the industry tipăritului: a more efficient
and more press. But his was the one that finally brought death. Only a few
inventions and those which they have achieved. This is the message of the

NANOTECHNOLOGY-TECHNOLOGY
OF THE NEAR FUTURE
Nanotechnology is a collective term for Nano scale technology
customized development. Nanotechnology is manufacturing a product with a
geometric size controlled at least one functional component has a particle size
of less than 100 nanometres. Physicist Richard Phillips Feynman’s first man
spoke about the technologies at the molecular level. Nanotechnology is the
technology of the future, enabling the introduction of new functionality in a
product. For instance, Bucky balls can be crowded in the form of cylinders,
called „nanotubes”. Nanotubes are made from fibre that can be included in
various materials, which are incredibly resilient. Wall paints with carbon fibber
and carbon black particles of Nano size acts as a screen against 99 % of highfrequency
electromagnetic waves. The 30 year Nano robots complexes will
appear – Nano doctors. And the examples can continue.
