Possible new green inventions for Pakistan and my suggestions

Below is an iPhone charger powered by a hand grip. It is powered by a person constantly squeezing it. This could be useful for all cell phone users in Pakistan who miss out on exercise and seek to save costs on electricity.

The only problem I find with this is most people with a cellphone in Pakistan have full time jobs and may not have the time to exercise their hands and when they're not working, they'll be too tired and busy resting. (Click on images to enlarge).


Below are lights that teach children how to save energy by changing colors. I don't know how it exactly works, but it be put in schools across Pakistan both in government and private schools.


These are staples that are supposed to be so bad to the environment that a company decided to create a staple-free stapler. This product promises to make collation eco-friendly. Instead of using those thin metal planet-killers, the staple-free stapler "cuts out tiny strips of paper and uses the strips to stitch up to five pieces of paper together." You can even order them customized with your corporate logo so you can, you know, brag about what your company is doing to stop the staple epidemic.

Companies in all over Pakistan could use this in their offices and others.


Designer creates a shower that forces you to leave when you've wasted too much water.
20% of our total domestic energy usage is from hot water for showering and bathing. That's over 6 times the energy usage of domestic lighting. So designer Tommaso Colia came up with his eco-friendly shower design that will force you to get out when you take too long and waste much water. The eco_drop shower features beautiful concentric circles that will rise to force you to stop showering when you take too long, and accordingly save water.

This is something hotels, households, public facilities and just about every place that uses a shower.


Designer creates a sink that uses wasted water to grow a plant. Made of polished stained concrete, the Zen Garden Sink has a channel that allows the water used while washing your hands to water a plant. Created by young Montreal designer Jean-Michel Gauvreau the sink comes in single or double basin model. The sink is designed in a way you won't get your plants all soapy. There is a main drain at the bottom of the basin for soapy grime. Your little plant friend just gets whatever you choose to dole out.

Perhaps this could be also installed in showers of houses in Pakistan that have gardens with a separate drainage that connects to the gardens?


University constructs a green roof as a gathering place. Green design is an enormously popular trend in modern architecture, just take a look at this amazing green roof at the School of Art , Design and Media at Nanyang Technological University in Singapore . This 5-story facility sweeps a wooded corner of the campus with an organic, vegetated form that blends landscape and structure, nature and high-tech and symbolizes the creativity it houses. The roofs serve as informal gathering spaces challenging linear ideas and stirring perception. The roofs create open space, insulate the building, cool the surrounding air and harvest rainwater for landscaping irrigation. Planted grasses mix with native greenery to colonize the building and bond it to the setting.

I don't really understand this so well, but my guess is places in Lahore, Karachi and Islamabad especially could use them if they help.


Company creates a desktop printer that doesn't use ink nor paper. Who says printers only use paper to print documents? It's time for you to meet the PrePeat Printer then. Different from conventional printers, PrePeat adopts a thermal head to print on specially-made plastic sheets. These plastic sheets are not merely water-proof, but could be easily erased, just feed the sheets through the printer again, and a different temperature will erase everything or just write over it. Also claimed by the manufacturer, such one sheet could be used up to 1,000 times so that you'll reduce your expenses on paper for sure.

This could be used in offices all over Pakistan, no question.


Disco pub gets electricity produced by people dancing at specially modified dance floor.
All the flashing strobes and pounding speakers at the dance club are massive consumers of electrical power. So Bar Surya, in London, re-outfitted its floor with springs that, when compressed by dancers, could produce electrical current that would be stored in batteries and used to offset some of the club's electrical burden. The club's owner, Andrew Charalambous, said the dance floor can now power 60 percent of the club's energy needs.

I doubt Pakistan could make much use of this as nightclubs are still not as popular in Pakistan.
Perhaps this could be used for floors of large public buildings and offices as well as airports that thousands of people pass through on each day.


Hotel offers free meal to guests who are willing to generate electricity.
The Crown Plaza Hotel in Copenhagen, Denmark is offering a free meal to any guest who is able to produce electricity for the hotel on an exercise bike attached to a generator. Guests will have to produce at least 10 watt hours of electricity - roughly 15 minutes of cycling for someone of average fitness. They will then be given meal vouchers worth $36 (26 euros).

These could be used at public gyms and health clubs all across Pakistan. It could reduce membership costs for customers and cover most of the electricity bills such as air conditioning.
