Hydrogen Fuel Technology Growing in Popularity
HyperSolar, Inc. (OTCQB: HYSR), the developer of a breakthrough technology to produce renewable hydrogen using sunlight and water, commented today on the significance of hydrogen growth in foreign countries, further signifying and advancing hydrogen fuel cell expansion. In just the last two months, Japan, Denmark, and the United Kingdom have announced significant technological breakthroughs and ambitious plans to support hydrogen fuel powered vehicles, and industrial and manufacturing development. On June 19, 2014, Japan laid out a timeline for objectives and actions over the next 25 years to commercialize fuel cell vehicles and utilize hydrogen energy applications for other areas of use. Similarly,…

Health Tips – 5 Ways to Use Tomatoes for Rosy Cheeks and Beautiful Skin
Tomatoes have often been called ‘the poor man’s apple.’ They have been called “the apple of love,” by the French. The Germans even called it “the apple of paradise.” In fact, tomatoes are more popular than apples as 60 million tonnes are produced around the world every year. As much as tomatoes are cheaper to buy than apples, they are rich in vitamins and enzymes that can help you achieve radiant health, from inside out. The humble tomato, which we don’t even give second thought to in this day and age, is actually laden with multiple health benefits. Here are…

Energy Storage – A Breakthrough Super capacitor for Storing the Energy of the Sun
Conventional batteries store electricity by changing the chemistry of their internal chemical compounds. During discharge, the chemistry is reversed and electrons leave the battery to power an attached load. The chemical reactions that convert electrical energy to and from chemical energy take time, therefore are slower to charge and discharge. This is the reason why you can’t charge your iPhone very fast. In technical terms, batteries exhibit low power density and high energy density. Unlike batteries, supercapacitors store charge in sub-nanoscale crevices through electric fields that naturally form inside its structure. During discharge, electrons rapidly leave through the terminal without…

CCNP (switch) – How to configure VLANs
How to configure VLANs? Suppose you have two members of IT department connected with fastethernet 0/3 and 0/4 ports of switch and you want to create VLAN 2 for IT department. And you have two members for HR department connected with fastethernet 0/7 and 0/9 and want to create VLAN 3 for HR department. Switch#config Configuring from terminal, memory, or network [terminal]? Enter configuration commands, one per line. End with CNTL/Z. (Creating VLAN 2) Switch(config)#vlan 2 Switch(config-vlan)#name IT Switch(config-vlan)#exit (Assigning membership of VLAN 2 to 0/3 and 0/4) Switch(config)#interface fastEthernet 0/3 Switch(config-if)#switchport mode access Switch(config-if)#switchport access vlan 2 Switch(config-if)#exit Switch(config)#interface…

CCNP (switch) – VLAN
VLAN (Virtual Local Area Network) Broadcast Domain Collision Domain HUB 1 1 Bridge 1 4 Switch By default 1 Each port contains separate collision domain Why you have to create VLAN? If you have one broadcast domain, than there is no privacy of any department in the company. There are two solutions to solve this problem. One is, provide a separate switch to each department, but this would increase cost. And the other solution is, you have to break one physical broadcast domain to multiple logical broadcast domains. One VLAN already exist on every switch and this VLAN is…

CCNP (switch)- Network Design
Network Design There are three layers of a network design: Access layer Distribution layer Core layer Each network design consists of minimum two layers of network design. Access layer: Where end users are connected, this is called as access layer. And the devises through which they are connected are called as access devices. Core layer: Layer which is directly connected to service provider (internet) is called as core layer. Distribution layer: Layer which provides services to above two layers is called as distribution layer. Policies are running on this layer. This layer is used for policies because we need speed…

CCNP (switch)
CCNP (Switch) The purpose of switch is to switch the data from one device to another. By default, switch is a layer 2 device. Cisco switches are known as Catalyst. A switch, which works on more than one layers of OSI model, is known as Multilayer switch. Cisco Switch Series: CAT 1900 and CAT 2900 are the series, which works on layer 2. CAT 3500, CAT 4000, CAT 5500 and CAT 6500 series switches are multilayer switches. You can check the model of a switch by show version command on privillage mode. Switch Ports: Interfaces on a switch which connects…

Things to Consider When Designing Your Low Energy Dream House – Part 1
Low Energy Dream House . – My wife and I are considering selling our home and building a smaller house set up for two people that makes efficient use of space and uses as little energy as possible. Since I make my living as an industrial energy efficiency and renewable energy expert this should be right up my alley right? It also sounds like a lot of fun designing our perfect new place that we will enjoy for many years to come. We started looking for designs off the internet for net zero or super-insulated homes which got us thinking…
