Scientists Invent 30 Year Continuous Power Laptop Battery!
Scientists Invent 30 Year Continuous Power Laptop Battery!
Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory. The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years.
Although betavoltaic batteries sound Nuclear they’re not, they’re neither use fission/fusion or chemical processes to produce energy and so (do not produce any radioactive or hazardous waste). Betavoltaics generate power when an electron strikes a particular interface between two layers of material. The Process uses beta electron emissions that occur when a neutron decays into a proton which causes a forward bias in the semiconductor. This makes the betavoltaic cell a forward bias diode of sorts, similar in some respects to a photovoltaic (solar) cell. Electrons scatter out of their normal orbits in the semiconductor and into the circuit creating a usable electric current.
The profile of the batteries can be quite small and thin, a porous silicon material is used to collect the hydrogen isotope tritium which is generated in the process. The reaction is non-thermal which means laptops and other small devices like mobile phones will run much cooler than with traditional lithium-ion power batteries. The reason the battery lasts so long is that neutron beta-decay into protons is the world’s most concentrated source of electricity, truly demonstrating Einstein’s theory E=MC2.
The best part about these cells are when they eventually run out of power they are totally inert and non-toxic, so environmentalists need not fear these high tech scientific wonder batteries. If all goes well plans are for these cells to reach store shelves in about 2 to 3 years.
Experts hailed the breakthrough as a potential “game-changer” as scientists seek to solve the world’s energy crisis. The small company from the north England has developed “air capture” technology which creates synthetic petrol with only air and electricity. Company chiefs say they have produced five litres of petrol in less than three months at a small refinery in Stockton-on-Tees, Teesside by removing carbon dioxide from the atmosphere. They now hope to build a large plant generating more than a tonne of petrol per day within two years – and a REFINERY size operation within the next 15 years. The fuel works in any petrol tank and promises to be “completely carbon neutral” so long as renewable energy is used to provide the electricity. The technology, pioneered by company Air Fuel Synthesis, was presented to a London engineering conference this week. It mixes sodium hydroxide with carbon dioxide before zapping the resulting sodium carbonate with electricity, to form pure carbon dioxide. At the same time, hydrogen is produced by electrolysing water vapour captured with a dehumidifier.
Breakthrough … scientists hope it could help solve the energy crisis
The carbon dioxide and hydrogen are then used to produce methanol which in turn is passed through a gasoline fuel reactor, creating petrol. The £1.1m project has been in development for the past two years and is being funded by a group of anonymous philanthropists. They unnamed sponsors hope it could prove to be a lucrative way of creating renewable energy. Stephen Tetlow, the Institution of Mechanical Engineers chief executive, hailed the breakthrough as “truly groundbreaking”. “It has the potential to become a great British success story, which opens up a crucial opportunity to reduce carbon emissions,” he said. “It also has the potential to reduce our exposure to an increasingly volatile global energy market.”
Members of the upper classes are more likely to lie, cheat and even break the law than people from less privileged backgrounds, a study has found:
In contrast, members of the “lower” classes appeared more likely to display the traditional attributes of a gentleman. It suggests that the traditional notion of the upper class “cad” or “bounder” could have a scientific basis. But psychologists at the University of California in Berkeley, who carried out the study, also suggested that the findings could help explain the origins of the banking crisis – with self-confident, wealthy bankers more likely to indulge in reckless behaviour. The team lead by Dr Paul Piff, asked several groups of people from different social backgrounds to perform a series of tasks designed to identify different traits such as honesty and consideration for others. Each person was asked a series of questions about their wealth, schooling, social background, religious persuasions and attitudes to money in an attempt to put them into different classes. The tasks included asking participants to pretend to be an employers conducting a job interview to test whether they would lie or sidestep awkward facts in pay negotiation. They were told that the job might become redundant within six months but were encouraged conceal this from the interview candidate. There was also an online game involving rolling dice in which participants they were asked to report their own score, thinking they would be in line for a cash prize for a higher score – and that no one was checking. Members of another group were given a series of made-up scenarios in which people spoke about doing something unethical at work to benefit themselves and then questioned to assess how likely they were to do likewise. The scientists also carried out a series of observations at a traffic junction in San Francisco. Different drivers’ social status was assessed on the basis of what car they were driving as well as visible details such as their age. Those deemed to be better off appeared more likely to cut up other drivers and less likely to stop for pedestrians. Overall the study, published in the Proceedings of the National Academy of Sciences, concluded that those from richer or powerful backgrounds appeared greedier, more likely to lie in negotiation and more likely to cheat.Being in a higher social class – either by birth or attainment – had a “causal relationship to unethical decision-making and behaviour”, they concluded.Dr Piff concluded that having an elevated social rank were more likely to display “self focused” behaviour patterns than those from more modest backgrounds, were less aware of others, and were less good at identifying the emotions of others. He said that the findings appeared to bear out the teachings of Aristotle, Plato and Jesus that greed is at the root unethical behaviour. “On the one hand, lower-class individuals live in environments defined by fewer resources, greater threat and more uncertainty,” he said. “It stands to reason, therefore, that lower-class individuals may be more motivated to behave unethically to increase their resources or overcome their disadvantage. “A second line of reasoning, however, suggests the opposite prediction: namely, that the upper class may be more disposed to the unethical. “Greater resources, freedom, and independence from others among the upper class give rise to self-focused social cognitive tendencies, which we predict will facilitate unethical behaviour. “Historical observation lends credence to this idea. For example, the recent economic crisis has been attributed in part to the unethical actions of the wealthy. “Religious teachings extol the poor and admonish the rich with claims like, ‘It will be hard for a rich person to enter the kingdom of heaven’.”
