Fuel-cell technologies are being used to generate power for telecom and industrial customers. Roll-out of the new technology has been dogged by technical problems and secrecy. Cleaner technologies are being developed to cut pollution from coal-burning power plants. The new cars will be energy efficient, environmentally friendly and technologically advanced. Although the technology originated in the UK, it has been developed in the US. Australia Launches $738m Fund To Support Green Tech In medicine, this era brought innovations such as open-heart surgery and later stem-cell therapy along with new medications and treatments . Scientific advances and the discovery of new concepts later allowed for powered flight and developments in medicine, chemistry, physics, and engineering. The rise in technology has led to skyscrapers and broad urban areas whose inhabitants rely on motors to transport them and their food supplies. Communication improved with the invention of the telegraph, teleph...
