Twitter-Like Tech For First Responders

Area: Health


Hospitals and First responders tend to have communication problems due to poor connection and surrounding noises at incidence scenes.

Twiage is a web-based app that enables first responders to easily snap and send photos to hospitals, as well as communicate important information regarding patients. This helps hospital better prepare and evaluate situations before patients are transported or before they arrive at the hospital.

In the latest version, the app is connected to Google glasses which makes the process even more user-friendly responders don’t need to use their hands to activate the function. They can easily send photos or messages using a voice-controlled option.


Stakeholders: Hospital / First Responders / Google


  • The company needs to contact hospital that are early adopters of technology to have them try Twiage
  • In parallel, the company needs to start working with major ambulance companies
  • The company should work with Google to help market their product and join they R&D efforts regarding Google glasses


Comment on other technology :

This technology has an interesting feature: the leaves are not static which means that they can get solar rays coming from more directions than regular panels.

HY4 to Change the Way We Travel (Sustainably)

  1. Sustainability Issue (Energy, Pollution):

Transportation consumes a lot of fuel and contributes to pollution and environmental harm. While all means of transportation contribute to greenhouse gas emissions, frequently flying can significantly increase your personal carbon footprint. According to CNN, “a flight from London to New York generates roughly as much emissions per person as the average European generates by heating their home for a whole year.”

  1. Summary of Technology (HY4):


  • HY4 is a zero-emission plane that is powered solely by a hydrogen fuel cell system and electric propulsion, with a battery to provide extra power during takeoff
  • The only emission generated by this plane is water
  • The plan is that HY4 could be used in regional transport such as electric air taxis, which would offer a faster alternative than driving, bus, or train.
  • Estimated that city to city travel in such planes could be commonplace in the next 20 years, with extension to large capacity, long haul flights within 50 years


  1. Stakeholders

Key stakeholders include:

  • Air travelers
  • Airlines
  • Aviation regulators
  1. Next Steps
  • Continue to demonstrate proof of concept with long range flights of existing plane
  • Continue development work on larger capacity aircraft
  • Explore extent to which hydrogen fuel cells can be incorporated into existing engine structure as an interim step to reduce emissions from passenger planes
  1. Comment on “How about use waste to build green artificial islands?”

This seems like a very interesting idea, though I would be interested to see a cost comparison between this proposal and the existing disposal methods. I fear the construction costs, particularly the underwater infrastructure to prevent leakage into the New York harbor, would exceed existing disposal costs. I also wonder how the compositing facilities (which can at times give off strong odors) would be integrated into the green space.

SaltX HeatBoost for heating hot water

Sustainable Problem: Energy Efficiency

Hot water is used in residential applications for washing dishes, clothes, and humans. Typically, there is a natural gas or electric hot water heater that heats a 30-50 gallon tank of water, maintaining the temperature around 120F before being delivered to its final purpose.

Technology Solution: SaltX’s HeatBoost Gas Powered Heat Pump

SaltX is a company from Sweden whose founding product is a salt crystal used for thermal storage. They also make a gas-powered heat pump used to heat hot water. They claim to be able to save 500 Euros per year with each installation with a simple payback of 1.5 years. It is clear from the company’s website, this solution is made for residential hot water heating.

The problem:

The thing that first caught my attention is the claim for 50% increase in efficiency. It doesn’t say over what, though. Most hot water heaters, especially those being sold now, are already 90-95% efficient, not leaving much for improvement. The second issue I have is the claim of 500 Euros savings per year. That would mean a family would have to spend at least 60 Euros per month just heating water. I’m not too familiar with the utility usage of Europe, but in the US, typically families only spend $10-20 per month heating water.

My job is being an Energy Engineer and all the time, we have to sift through new technologies. These are simple questions that get brought up as part of our job and are addressed before supporting a product. We would need to verify the claims of savings and determine how the technology works. Without talking with the company, it seems like these are dubious claims.

Next Moves:

This company is working with the Northwest Energy Efficiency Alliance and Rheem to break through the US market. It’s a good strategy. If they can get the recommendation of the utility company, getting trust in the public is easier. If they are going after the residential market, it will be much more difficult to market to all of the different people buying hot water heaters. A good solution is to market to Energy Services Companies, which have customers interested in energy efficient products. Some commercial applications, schools, universities, etc have higher hot water uses, but again, the efficiency of these systems is over 90% and I would wonder if SaltX makes a HeatBoost large enough to meet those demands, certainly not at 750 Euros.

Organizational Stakeholders:

Homeowners, Utility Companies, Building Owners, Energy Services Companies, Mechanical Contractors.

Article – “World’s first “negative emission” plant”
Great find! I’m so interested in the cost aspects of this and how it compares to energy efficient measures, renewable energy, and other carbon capturing technology. The article states their goal is $100 per metric ton, but can go as low as $30. That would be great and definitely worthwhile. Also, I wonder how a localized plant would be able to have an affect on a global issue…

Energy from Evaporating Water could rival Wind and Solar.

Ch2217 is my uni.


1: Energy, air, water









This machine could harness the energy from water that evaporates from existing dams and lakes in the U.S. It could provide up to 2.8 billion megawatt hours per year or about 2/3 of the electrical production in the U.S in 2015.


3: Stakeholders are anyone currently using electricity generated by burning fossil fuels. Additional stakeholders would be less developed nations who would not have to spend billions upgrading their infrastructure to burn fossil fuel burning generating plants.


4: If this technology can be refined it would sell itself to countries, states and cities currently using fossil fuels to generate electricity or facing huge infrastructure upgrades to generate electricity using fossil fuels.


My comment: For the rapid electrical cell recharging technology article;

I particularly like the safety improvement offered by this technology. The removal of the membrane in the fuels cells which become clogged and cause overheating and fires makes this technology important for the future of transportation fuels cells being utilized on a larger scale


Fashion’s solution to waste methane

Sustainability problem:

Methane is a greenhouse gas contributing to climate change by trapping heat in the atmosphere.

Methane is emitted by natural sources, but also by human activities such as leakage from natural gas systems, landfill and dairy farms.

CH4 is more efficient at trapping radiation than CO2: the comparative impact of CH4 is more than 25 times greater than CO2.


Mango material is a startup using Methane to create fabric for apparel. The technology involves using waste methane to feed bacteria that then produce PHAs, a fully biodegradable bio-polyester fiber that can be turned into thread.

Mango Material is currently working on a pilot project, with a wastewater facility in California.


  • Waste facilities
  • Apparel companies
  • Apparel consumers
  • Textile industry
  • NGOs
  • General population


  • Expand network of waste facilities to recycle waste methane
  • Develop technology to expand Methane sourcing to dairy farms and natural gas leakage
  • Implement an awareness campaign on the technology and quality of product
  • Business development campaign to partner with apparel companies


Scientists Create Robotic Replacements for Declining Bee Populations

Ch2217 is my uni.


1—Health, Food



Bee populations are collapsing worldwide, as a potential solution for the replacement of their pollination duties, researchers are creating robotic replacements for them.


3—The stakeholders are owners and operators of vineyards, orchards and farmers in general.


4—I would market this development to beekeeper associations as well as directly to consumers of the beekeeper’s services. Perhaps to augment the present population of bees, to reduce the pressure on weakened bee populations

My Comment is for The Smart Yarn Tech Article. I appreciate how important it is for this tech to communicate alarms after an impact, I am curious however as to it being properly insulated so that even after repeated wear, would it retain it ability to be waterproof.

The FarmBot Genesis Brings Precision Agriculture To Your Own Backyard

by Andrew Hayward
Published 6/27/2016 on modern farmer at

  • A three-person team from California has developed a data-enabled machine to sow and water seeds in small gardens.
  • The FarmBot Genesis is pre-programmed to optimize spacing and watering for thirty three common plant varieties – but the open source coding means that it can be adapted by the user for specific applications.
  • The bot can be controlled from a smartphone or computer, and users can customize plantings using in a simple interface that looks like a computer game.
  • The current system can manage a plot up to 2.9 meters × 1.4 meters, with a maximum plant height of 0.5 meters – but there is potential to develop and customize the technology for a variety of applications.

3. Organizational Stakeholders

This technology is now available for pre-order, and the immediate stakeholders will be:

  • Backyard farmers
  • Urban agriculture organizations and cooperatives

Because the technology is open source and has potential for development, future stakeholders could include:

  • Operators of commercial-scale greenhouse operations
  • Plant researchers working in controlled environments

4. Deployment

The next three stages in deploying this technology could be:

  • Creators: disseminate the Genesis model
  • Early adopters: identify value-add applications
  • Creators: scale up manufacturing to bring cost below $1000/unit
