Bêtavoltaïque
Bêtavoltaïques cells are generating power, developed 50 years ago, using energy sources emitting radioactive electrons. Tritium, isotope Hydrogen is a commonly used source. This is a passive process, unlike that used in nuclear power plants for which causes collisions between radioisotopes.
Biometrics
Mathematical analysis of biological characteristics of a person to determine his identity conclusively. Biometrics based on the principle of recognition of physical characteristics. The fingerprintsAnd the range of indices generally referred to biometrics, including iris, retina, Hand and voice prints, offer irrefutable proof of the identity of a person as they are unique biological characteristics that distinguish one person from another and can be associated to one person. Suitable for Internet, Biometrics makes it possible to filter access to sites and commercial Intranets. Biometrics can be the ally of privacy to safeguard our identity and theintegrity data.
