The eye is designed to allow one to focus at different distances. It does this by reshaping its own internal lens and hence changing its power. The lens are attached to a muscle. To see the nearby object, contraction of the ciliary muscle will make the lens thicker and more curved, and thereby decreases it’s focal length. To see distance object clearly, the muscle relaxes to the decreases the curvature of the lens and thereby increases its focal length . The process is called accommodation.

To focus for close objects, the lens needed to be made fatter to provide more power. In a young person the lens are very soft and jelly like and easy to reshape. Throughout our ...

Are you ever on the go and find that your cell phone battery is running low? Isn't it a pain in the butt when this happens? All too often, when we're on the go outdoors we simply don't have access to a plug to charge up.

We at Sol Power LLC grew tired of being on the go and never having outdoor charging options available when our cell phones were dying. Nothing's more frustrating than searching frantically for the nearest Starbucks to find a charging outlet when your battery is down to that last bar.

We recognize people today use their phones to do just about everything, and that we need charging solutions in more convenient locations to support ...

For over 33 years I have proposed the following "free lunch" solution to "movers and shakers" in the US and internationally, without obtaining any cogent replies or rebuttals.

The only remaining well paying jobs left in our slow recovery are in the Defense Establishment, which are presently used for "make work" jobs on weapon systems unsuitable to the War on Terror. A more suitable use for the Defense sequestration, which will be fully paid for, and will ultimately reduce deficits and pay off the National Debt is presented following:

In order to recover from our present malaise, we need a huge infusion of government funds similar to those of World War II, which brought us out of the Great ...

This generator uses solar and/or electricity supply from power holding company of Nigeria (PHCN) to charge battery which is connected to the inverter for alternating current output. the generator does not use Diesel oil, petrol or any other hydrocarbon fuel as it does not as well, use an internal or external combustion engines.It is a stationary, silent, clean and sustainable source of electricity production. The machine can however, be used as stabilizer during low voltage supply from the PHCN. The generator comprises of seven major sub-systems. They are the solar module, the PHCN supply, the charge controller, the battery, the inverter, system architect and the control panel.

The generator is initiated by a solar and/or PHCN charge to the ...

This design is all about sustainable personal transportation and maximized energy efficiency without relying on non-renewable energy sources like fossil fuels. The fuel for driving this vehicle is extracted from sunlight by high efficiency but conventional silicon solar cells, which you may even find on your neighbours rooftop. The sunlight is converted into electrical energy which is used directly for driving the car or is stored in the lithium battery pack in case of a surplus of energy. That’s right, this car may very well reach a velocity of 80 km/h and still produces a surplus amount of energy due to the extremely high energy efficiency >90% and the extremely low energy expenditure due to a lightweight carbon monocoque ...

Two common features are generally found with every human activity: the presence of light, either from the sun or man made sources, and the presence of fibers, such as in the clothes we wear. Now imagine if the fibers making our clothes are efficient converters of light into energy. This would not only help make individuals more energy independent, but enable scaling up of light energy harvesting products to carpets, curtains, tents, and even textile-based solar farms, as shown in the figure. One can also envision immediate impact in scenarios requiring energy sources far away from convenient locations, such as when rescue workers and the military are deployed in disaster effected or remote areas.

Our patent pending design for ...

The P.C.D. - Prominence Commuting Device, proposes a sustainable and attractive battery-powered single-seater electric vehicle.

We have been demonstrating our concept using bicycle components that anyone can buy on general market. This concept can rebuild the way of mobility as people's daily transportation. In addition, new culture of DIY - with intellectual excitement, is born when anyone can produce a very compact mobility like the P.C.D.

The P.C.D. has a highly functional electric propulsion system with KERS -Kinetic Energy Recovery System, at low cost. This system is composed of electric hub motor-500W of rated output and a motor controller for an electric bicycle. Anyone can buy these components on general market at an affordable price.

What is more important ...

Today we are faced with Climate and Environment challenges. In the past few years I had seen on www.LinkedIn.com lots of issues on this topic. Some say we should require Green Energy and other people say trees should grow but what  in the present situation are we not thinking about?

To make Green Energy what we require our vehicle emission should be eco-friendly and if there is vehicle how much percent people are buying and still today’s vehicles are not 100% pure eco-friendly.

To grow trees we require small plants and from this stage to become a full tree it will take 4 or more years and within this time between 0 to 4 yrs lots of changes ...

You will be shocked to know that-Globally 1.3 billion tonnes of food are wasted per year due to lack of proper processing.On the other hand, according to the head of the U.N. food agency 18,000 children die every day because of hunger and malnutrition. So, food processing should be emphasized to promote food security and combat hunger and reduce that huge losses. Drying is one of the oldest and easiest method of food processing. But conventional (convective) drying takes longer drying time and food quality of food degrades during drying. Our new drying method, solar microwave drying, which will improve both energy efficiency and product quality in drying. Application of microwave boost up the drying process by driving the ...

The impact of climate change on coastal communities in the Canadian and other circumpolar Arctic requires building more robust sustainable community infrastructure with less dependency on outside resources. The melting of permafrost and the erosion of shorelines due to both permafrost melt and increasingly violent storms in the Arctic Ocean as the ice cover decreases requires a redesign of Arctic communities if they are to be sustainable in the future.

Housing can be built using a shell concept with greater flexibility of the support structures that enable simple methods of adjustment to cope with permafrost melt and also allows for the movement of the whole structure should the shoreline be endangered by the action of storms such as is ...
