3 Inventions that Should be Created
The world we live in is in constant evolution, and the last century has brought changes of modern life more than in millenniums of gradual progress before. The technological advancement is explosive and today dreams are the realities of tomorrow.
Interstellar travel
With interstellar travel we have been fairly well familiarized for some time through reading and the science-fiction films. The term suggests a a vehicle moving through [..]
Multicast Traffic – Ethernet
Most industrial producer-consumer (or publisher-subscriber) protocols operating over Ethernet, such as EtherNet/IP and Foundation Fieldbus HSE, are IP multicast-based. The first advantage of IP multicasting is network efficiency; by not repeating the data transmission to the multiple destinations, a significant reduction in network load can occur. The second advantage is that the sending host need not be concerned with knowing every IP address of every destination host listening for the [..]
Is it a good have 2 firewalls running simultaneously ?
We recommend that you run only one antivirus and one firewall at a time. Having more than one antivirus or firewall active in memory uses additional resources and can result in software conflicts, network and software access problems and false virus alerts. Your best defense against computer viruses and malicious programs is to keep your antivirus virus definitions up to date and update your antivirus and firewall to lasts [..]
Distributed Firewalling
Distributed firewalling is an emerging security technology in firewall deployment that moves security from the perimeter to device endpoints. This is accomplished by placing a firewall in or directly in front of every endpoint and other appropriate devices in the network. The theory of distributed firewalling is that this can ease the burden on the perimeter and internal firewalls, which have traditionally been major chokepoints for network access. As distributed [..]
Firewalls Testing
New firewalls should be tested and evaluated before deployment to ensure that they are working properly. Testing should be completed on a test network without connectivity to the production network. This test network should attempt to replicate the production network as faithfully as possible, including the network topology and network traffic that would travel through the firewall. Aspects of the solution to evaluate include the following:
- Connectivity. Users can establish and [..]
Three Cheap Solar Projects
Solar fountains
Solar fountains offer all the beauty and elegance of any other type of fountain for under $100.
The water will flow when the sky is sunny and cut back when it’s cloudy. You’ll be aware of how much sunshine you are receiving at any given time.
You can locate a solar fountain anywhere, as long as you put the PV panel in sunlight.In order for the fountain to run at night[..]
Electric Vehicle Availability
Electric vehicles (EVs) are available as neighborhood electric vehicles (NEVs) and as scooters and bicycles. Conversion kits are also available to transform a conventional light-duty vehicle into one that runs on electricity.
Current Electric Vehicle Models
- Neighborhood Electric Vehicles
- Electric Bicycles
- Electric Scooters
Electric Vehicle Conversions
The cost of converting a gasoline-powered vehicle to an electric vehicle can be high. Electric cars [..]
What is an Electric Vehicle ?
In an electric vehicle (EV), a battery or other energy storage device is used to store the electricity that powers the motor. EV batteries must be replenished by plugging in the vehicle to a power source. Some electric vehicles have onboard chargers; others plug into a charger located outside the vehicle. Both types, however, use electricity that comes from the power grid. Although electricity production may contribute to air pollution [..]
Grid-Connected Small Wind Electric Systems
Small wind energy systems can be connected to the electricity distribution system. These are called grid-connected systems.
A grid-connected wind turbine can reduce your consumption of utility-supplied electricity for lighting, appliances, and electric heat. If the turbine cannot deliver the amount of energy you need, the utility makes up the difference. When the wind system produces more electricity than the household requires, the excess is sent [..]
Wind Turbine Power Generation | Industry Growth
The development of wind turbine power generation has been expanding during the past 10 years.
The global market for the electrical power produced by the wind turbine generator (WTG) has been increasing steadily, which directly pushes the wind technology into a more competitive arena. Recently, there have been positive trends shown by the utilities to offer renewable energy to customers. Many customers who are environmentally conscious now have the option of [..]
