Planetary phase of civilization - Wikipedia, the free encyclopedia - 1 views

  •  
    Michio Kaku says in his book that all technological revolutions are leading to the creation of a planetary civilization. "The planetary phase of civilization is a concept defined by the Global Scenario Group (GSG), an environmental organization that specializes in scenario analysis and forecasting. Proponents of the planetary phase of Civilization State that it refers to a current historical transition from a world of capitalist states and consumerist societies to a world of increased global connectivity with new global institutions (like the United Nations and the World Trade Organization), new information technologies, environmental change in the biosphere, economic globalization, and shifts in culture and consciousness. Although the concept is hotly debated in some circles, most reputable scientists give little credence to the theory and assert that current global economic interconnectedness is a function of advanced technology rather than the emergence of anything new in cultural or sociological terms."

Superconductor Uses - 0 views

  •  
    possibly used in flying cars    Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to "float" on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have to be physically much larger than superconducting magnets. A landmark for the commercial use of MAGLEV technology occurred in 1990 when it gained the status of a nationally-funded project in Japan. The Minister of Transport authorized construction of the Yamanashi Maglev Test Line which opened on April 3, 1997. In December 2003, the MLX01 test vehicle (shown above) attained an incredible speed of 361 mph (581 kph)."

    nanotechnology is a branch off of nanotechnology. they are small machines that can be used for anything. "Nanorobotics is the emerging technology field creating machines or robots whose components are at or close to the scale of a nanometer (10−9 meters).[1][2][3] More specifically, nanorobotics refers to the nanotechnology engineering discipline of designing and building nanorobots, with devices ranging in size from 0.1-10 micrometers and constructed of nanoscale or molecular components.[4][5] The names nanobots, nanoids, nanites, nanomachines or nanomites have also been used to describe these devices currently under research and development"

We all know that hydroelectricity is both renewable and green, but what are the other advantages this technology offer? Are there any disadvantages?

Wind Energy Pros - 0 views

  • Cons of Wind Energy Wind is highly variable. Wind speed varies by numerous factors, including weather, location and season, so not all places are appropriate for wind energy. At Inn Serendipity, we rarely overproduce electricity during the summer months. Equipment requires a sizeable upfront investment, depending on the size of system selected. To meet the needs of a modest hobby farm, like ours (after energy conservation and efficiency efforts have been exhausted), a 10 kW system that costs $40,000 to $70,000 would be needed to become a net producer of electricity on an annual basis. Evaluating projected wind-system output is difficult due to variability of turbine design and production conditions. “Wind turbines are not created equally,” Hippensteel says. “Some require considerably more maintenance and service than others.” Living with a renewable energy system demands a more energy-mindful way of living. After any big storm, we check our inverters in much the same way that our farmer neighbors check on their animals. State or municipal zoning laws may result in expensive hearings or possibly prevent you from erecting a tower of sufficient height. NIMBYism: Some neighbors may voice objections to the sight or sound of a swishing turbine. While possible harm may be done to birds, research studies, such as one by the National Wind Coordinating Committee, have found that collisions with windows in buildings and vehicles, capture by outdoor cats, as well as poisoning due to chemicals cause far more avian fatalities than encounters with residential wind systems. Depending on location, securing capable technicians or service workers for possible repair or maintenance can add significant costs to owning a system.

    "Pros of Wind Energy Wind is renewable, freely available and tax-free. Farm businesses may even be eligible to receive a wind-production tax credit. No pollution or waste is generated by the system's operation. Depending on the wind turbine selected, the equipment can be low-maintenance. In general, the more complex the system and the moving parts, the more likely repairs or maintenance will be needed. (Note: After five years, our 10 kW Bergey's generator and inverter required no special repair.) A growing number of utility companies offer simple net metering contracts. (More than 40 states have net metering according to the Database of State Incentives for Renewables and Efficiency.) Under net metering, a wind energy system owner would receive credit for at least a portion of the electricity they generate. There are numerous statewide wind-energy financial incentives, according to Database of State Incentives for Renewables and Efficiency. Numerous national manufacturers of wind turbines have proven reliability track records, including Bergey, Proven, Abundant Renewable Energy, Wind Turbine Industries Corp., and Southwest Windpower, according to John Hippensteel, and engineer with Lake Michigan Wind and Sun, Ltd. Land within the acre or two needed for a residential wind turbine can still be used for pasture, gardens or other agricultural purposes. In our experience-as as noted by the American Wind Energy Association, the Midwest Renewable Energy Association and others-as of 2009, wind is the most cost-effective source of renewable energy, especially when compared to solar electric (photovoltaic) systems. Depending on the system and electricity rates, which continue to rise, your investment might break even in about 17 years."

    "It might look like two circuit boards trapped inside some glasses, but Avegant's prototype Virtual Retinal Display (VRD) is not your run-of-the mill head-mounted display (HMD). Using an array of two million micro mirrors, this dorky-looking pair of spectacles is able to deliver an incredibly sharp virtual 3D experience by projecting two separate images directly onto each of your retinas."

Virtual retinal display - Wikipedia, the free encyclopedia - 0 views

  •  
    "A virtual retinal display (VRD), also known as a retinal scan display (RSD) or retinal projector (RP), is a display technology that draws a raster display (like a television) directly onto the retina of the eye. The user sees what appears to be a conventional display floating in space in front of them. (However, the portion of the visual area where imagery appears must still intersect with optical elements of the display system. It is not possible to display an image over a solid angle from a point source unless the projection system can bypass the lenses within the eye."

Advantages and Disadvantages of Solar Energy - 0 views

  •  
    "Advantages of Solar Power? Solar energy is a clean and renewable energy source. Once a solar panel is installed, solar energy can be produced free of charge. Solar energy will last forever whereas it is estimated that the world's oil reserves will last for 30 to 40 years. Solar energy causes no pollution. Solar cells make absolutely no noise at all. On the other hand, the giant machines utilized for pumping oil are extremely noisy and therefore very impractical. Very little maintenance is needed to keep solar cells running. There are no moving parts in a solar cell which makes it impossible to really damage them. In the long term, there can be a high return on investment due to the amount of free energy a solar panel can produce, it is estimated that the average household will see 50% of their energy coming in from solar panels.   Disadvantages of Solar Power? Solar panels can be expensive to install resulting in a time-lag of many years for savings on energy bills to match initial investments. Electricity generation depends entirely on a countries exposure to sunlight; this could be limited by a countries climate. Solar power stations do not match the power output of similar sized conventional power stations; they can also be very expensive to build. Solar power is used to charge batteries so that solar powered devices can be used at night. The batteries can often be large and heavy, taking up space and needing to be replaced from time to time."
