Solar Ivy-The new future of Sustainable Design

The problem:Integrating solar panels in building facades can pose as a challenge given the shape,orietaton and angle at which solar panels have to be placed.

The solution and technology :Solar Ivy ,a  system of thin, fluttering solar panels in shape of a leaves  that generate energy by sparkling in the sunlight. These panels can be easily integrated to the side of a building.The Solar Ivy consists of a thin film like material on top of a polyethylene with a piezoelectric generator attached to each leaf. When the sun is shining or the wind is blowing, energy is being generated via Solar Ivy.

Stakeholders:1.Makers of Solar Ivy.


3.Building Homeowners


1.Developthe best possible shape of the solar leaf to maximise the capacity to absorb sunlight.

2.Work with architects and engineers to increase aesthetic appeal and energy generating capacity.

3.Make these solar leaves cheaper to buy and easy to install.

4.Train building owners or  building facilities managers on maintaining the Solar Ivy efficiently.

This is something that would definitely work given the amount of coffee consumed int he world.However, collecting these coffee grounds will be a challenge given people are careless about how they throw their waste.A proper collection system needs to be planned out in order for this to work.Coffee ground bins and some small form of a rebate for coffee shop owners is the way to go!

Smart Cooling technologies for Data Centers


Data centres today generate huge amounts of heat.This impacts the hardware systems functions in the data centre.Therefore,cooling is a major requirement in data centres .Electricity costs from data centres take up a chunk to the IT budget each year.

The Technology:

Dynamic Smart Cooling  technology combines sensors with control nodes that monitor temperatures in parts of the data center. These nodes control the computer room air conditioners for better control of the whole IT environment, so you don’t have to cool a whole room for a few racks in one area.This technology can help reduce  the power to cool a data centre from 30-60 percent.

Vigilent is a company that develops smart cooling technologies for Data Centre.The Vigilant Dynamic cooling System consists of four main components:monitoring, dynamic control, analytics, and extensive alarms.These components work together in reducing energy costs.

The monitoring system uses wireless sensors to determine the data centre’s thermal environment.The dynamic control uses machine learning and combines it with the temperature data gathered from the monitoring device and determines how to best adjust the data centre’s resources  to match the current heat load, all while using the minimum amount of energy possible.The analytics  that is built on advanced AI technology transforms  Data into actionable information to model  Airflow ,subtle interactions between cooling resources and identify  heat load.The alarm notifies when human intervention is required during issues with the cooling system.


1.IT companies with Data Centres

2.Energy Engineers

3.Developers of Vigilant.


1.Develop technology to suit requirements of all data centres.

2.Work with all major IT companies with Data Centres to deploy this technology.

This I brilliant and works very well in cities.I visited Norway this summer and the streets are planned in a way that have multiple electric vehicle charging stations.There is also free street parking for electric vehicles in Norway.Tesla is heavily subsidised in Norway too!Time for other countries in the world to take this example!


Wakati:Keep food fresh using solar power


Keeping food fresh in areas without refrigerator or electricity.


A solar-powered,sterlized microclimate called WAKATI that stores and ventilates food and vegetables.It consists of a tent-like box with a 3W solar panel on it.he solar power runs a ventilator that gradually evaporates a weekly supply of about 6.7 oz of water, creating a humid environment within the Wakati that keeps produce fresh.

Crops can dry out quickly after being harvested, but with the Wakati system the humidity keeps the cells of the crops intact and the acids and enzymes inside the cells that would normally begin to digest the crops are kept under control.


1.Farmers, specially in developing countries who can keep their produce fresh for long and can earn profits.

2.Makers of Wakati.

3.Citizens of developing countries where electricity is inaccessible.


1.Increasing the  storing capacity of Wakati and manufacturing it on a larger scale to make it affordable for citizens in developing countries.

2.Providing Wakati to farmers in a subsidised rate by partnering with local agriculture government agencies.

3.Demontrating and showing citizens specially women on how to use it effectively.

Very important solution given the world is facing so many natural disasters.But this will take a long time to deploy as it involves so much planning and intervention of its governments.As you mentioned institutions like hospitals need this technology so a smarter way to approach it would be to public private partnerships.



Mitticool-Keeping food fresh without electricity

Environmental Problem:

Refrigerators  pose a huge problem today as they emit toxic HFCs which  reduces ozone layer, pose health risks and also consume a lot of electricity.


“Mitticool” -a refrigerator is completely made of clay and consumes no amount of electricity to keep food fresh.

How it works:

Mitticool works on the principle of evaporation. Water from the upper chambers drips down the side, and gets evaporated taking away heat from the inside, leaving the chambers cool. The top upper chamber is used to store water. A small lid made from clay is provided on top. A small faucet tap is also provided at the front lower end of chamber to tap out the water for drinking use. In the lower chamber, two shelves are provided to store vegetables, fruits and milk etc.



1.Makers and distributors of Mitticool

2.Homeowners:Will significantly reduce utility bill costs for homeowners using Mitticool.

3.Citizens:Improved air quality and less GHG emissions.


1.Increase the production of MittiCool and increase its size to fit more contents.

2.Increase awareness among citizens on the benefits of electricity free refrigerators.

3.Make Mitticool more accessible to rural and urban residents.

Solar Crematorium:Solving India’s problem of pollution from Crematoriums

Background and environmental problem:In India,the body of a person is burnt according to the Hindu traditions using logs of wood that causes air pollution, respiratory problems to nearby residents  and cutting down of trees.Between 500-600 kg of wood is required to burn one body.

Solution:Pollution free solar crematorium that uses  concentrated solar energy to burn the dead body.The processes involved in this technology are:

  •  Igniting the dead body locally with the help of a huge concentrating reflector having very high CR and to maintain the combustion of dead body by supplying the fresh atmospheric air with the help of blower.
  • Once combustion of dead body starts within the cremation chamber, it also releases heat which automatically in combination with solar energy obtained from concentrating reflector maintains continuous burning of dead body until complete dead body gets converted into ash.Screen Shot 2017-10-04 at 23.30.04.pngdead body until complete dead body gets converted into ash.


Organizational Stakeholders:

1.Concentrated solar reflector distributors.

2.Solar Engineers.

3.Religious Groups.

4.Local Citizens living  close to the crematorium.


1.First step is to educate religious groups and citizens of having a wood free crematorium.

2.Partnering with local solar engineering firms to develop the technology.

3.Working with local municipalities to help fund the project.

Building low cost Air Conditioners using only water and terrra-cota

Week 2

Environmental Problem:Release of harmful CFCs and HFCs from refrigerants.

In many developing countries during peak summers, the pollution from air conditioners is huge and utility bills are the highest.

The solution:Building a low cost air conditioning system that is built using  cone shaped terracotta pots arranged to from a beehive pattern.The evaporative cooling starts when water is poured onto the terracotta structure using a motor.The porous terracotta pots absorb water, and as hot air passes through them, it is turned into cool air.

The model can be built anywhere, in remote locations with a consistent electrical grid. But in regions that suffer a shortage of power supply, the model can work as a zero-energy installation with the manual pouring of water over the pots.


1.Architects/engineers will have more contracts to build this technology.

2.Rural/Urban homeowners save money spent on air conditioners and utility bills.

3.Factories/Large facilities that can use recycled water from their operations and deploy this to cool their surroundings and save money.


1.The first step is to educate homeowners/facility owners where this technology can be deployed about the cost savings and effectiveness of the system.

2.Make it a part of building code to provide provisions for implementation of this technology.

3.Employ good architects/engineers to effective build this technology.

Hydronic heating:Energy efficient heating for homes


The problem:

Regular heating appliances increase utility bills and also add to the carbon emissions in the atmosphere.

The solution:

Hydronic heating provides residential heating at a lower cost by lowering utility bills and also has a very low impact on the environment.

How it works:

Hydronic heating uses  tubing to run a hot liquid beneath the floor, along base board heaters, or through radiators to heat a home.The heated liquid ( heated via a source like boiler) is circulated through loops of plastic piping.These are more viable in new construction as they can be installed within the concrete slabs.The liquid is then returned for reheating  via a reticulating system.



  • Homeowners:Reduce their utility bills but also have the benefit of cleaner air as there are no suspended particles in the air.
  • Contractors:Installing more hydronic heating will provide more income for the contractors.
  • Pipe suppliers/manufacturers:More pipe manufactures will profit from an increased used of hydronic heating.
  • Developer/Building owners:Energy savings for the building and reduced dependence on traditional heating equipment lowering maintenance costs for the building owner.


  • Provide tax incentives to homeowners/building owners to increase the use of hydronic heaters.
  • Implement hydronic heating as a part of building code.
  • Educate homeowners/building developers on the benefits of hydronic heating.
