JUSE: World’s First Solar Nano Smartphone Charger


1) As smartphone usage continues to grow and devices evolve to support more applications, this represents a large power draw – more devices and more frequent charging. In addition, as mobile phones offer more services for residents in developing countries, these cannot be utilized in areas without consistent access to power.

2) JUSE is the first perpetually powered solar nano case for smartphones.

  • JUSE incorporates the most efficient Photo Voltaic Cells (PVC) available (up to 2-3 times more efficient than the typical cells used in current external cell phone chargers) to store energy in a nano battery
  • JUSE charges your phone automatically, removing the need for traditional charging
  • It takes about 2 hrs of sunlight to charge JUSE to 75%, so combining outdoor light with indoor light provides perpetual power for the whole day.
  • JUSE is designed to work under low light conditions, but shouldn’t be left for 24 hours in a pocket or purse with no light
  • Replaces protective cases purchased by the majority of smartphone users

3) Organizational stakeholders: Smart phone users in both developed and developing nations, NGOs, mobile service providers

4) Steps to deploying the technology:

  • Publish performance results from initial users from Indiegogo campaign
  • Partner with AT&T or Verizon on a promotion to reach new users and fund additional production
  • Consider partnering with several device manufacturers on a revenue share to become the default case/charger

Rain Tunnel: Drinking water from moisture in the atmosphere

1) Millions of people around the world don’t have access to safe, clean drinking water. Increasing droughts are worsening the problem and could leave more people without access to clean water.

2) A Bangalore-based scientist has developed Rain Tunnel technology to produce clean drinking water from moisture in the atmosphere.

  • The Rain Tunnel uses a “Hypersonic Precipitator,” which employs extreme high-frequency sound waves to produce nano-water particles. The nano-particles can freeze at temperatures as high as 50-60 degrees Fahrenheit, and form ice crystals through vapor deposition in the precipitator chamber.
  • The “rain” is collected in a food-grade tank and treated with a five-stage process only when you are ready to drink, to avoid risk of stagnant water becoming contaminated.
  • The group has designed a household plug-in machine that can produce 30 liters of clean drinking water for a family, which it expects to be ready for commercial use by September.
  • As the first version will be plugged in, it will not address areas without electricity, but there are plans to ensure the device can leverage renewable energy sources like solar, wind or biomass.
  • Using water from the atmosphere is not a new idea, but previous technologies required energy-intensive systems to chill the air and high atmospheric humidity over 65 percent. The Rain Tunnel technology does not require very low temperatures to produce water, and depends on atmospheric conditions such as water vapor pressure, temperature, altitude and wind flow, instead of humidity.

3) Organizational stakeholders: Residents in areas with frequent droughts and/or lack of clean drinking water, senior government leaders, local government, small businesses, NGOs

4) Steps to deploying the technology:

  • Partner with several communities to conduct pilots to ensure device is ready for production & household use
  • Increase production and target communities that have access to the grid or community solar installation but face water shortages
  • Partner with NGOs that provide home & community solar installations

Jet fuel from municipal solid waste

TechnologyDiagram-Fulcrum Bioenergy

1) Airlines account for 3% of the U.S.’s GHG emissions and 2% of the world’s GHG emissions. Airlines are increasingly under pressure to reduce carbon emissions, but the development of sustainable, affordable biofuels has been a challenge.

2) Fulcrum BioEnergy, Inc. has developed a proprietary thermochemical process that converts municipal solid waste, or MSW, feedstock into low-carbon renewable transportation fuels including jet fuel and diesel.

  • Fulcrum will extract commercially recyclable material and inorganic waste from the MSW, then send MSW feedstock to the Biorefinery.
  • Gasification of the MSW feedstock produces a synthesis gas (syngas) consisting primarily of carbon monoxide, hydrogen and carbon dioxide, which is purified and processed through the Fischer-Tropsch (FT) process to produce a syncrude product which is then upgraded to jet fuel.
  • The fuel will qualify as an “Advanced Biofuel”- independent analysis shows a net lifecycle reduction in CO2 emissions of over 80% vs. petroleum fuels.
  • United Airlines’ $30 million equity investment in Fulcrum is the single largest investment by a U.S. airline in alternative fuels.

3) Organizational stakeholders: United Airlines, other domestic and international airlines, governments who will support biofuels development, environmental groups

4) Steps to deploying the technology:

  • Focus on first phase with United – complete joint testing
  • Increase production to deliver 90 million gallons per year to United as agreed
  • Proceed with option for joint development of up to 5 projects near United’s hubs that could produce up to 180 million gallons of fuel per year

The Finite Faucet

Finite Faucet

1) As water shortages become more widespread due to droughts, population growth, etc., new technologies for water conservation are needed.



2) Finite Faucet is a new design for a water-saving public restroom faucet installation.

  • Based on CDC guidelines for handwashing that only require two short bursts of water – once to wet your hands, and once again to rinse off the soap
  • The Finite Faucet is made almost exclusively of reclaimed metals, plastics, and parts, and can be fully recycled again at end of lifespan
  • When you turn on the Finite Faucet, it drains until it is empty, and must be turned off to refill
  • Upper cylinder acts as a visual reminder of water usage
  • Refilling water acts as timer for scrubbing your hands (20 seconds)

3) Organizational stakeholders: facilities managers in corporate offices, airports and other transportation facilities, etc.

4) Steps to deploy:

  • Contact management at airports scheduled for renovation, to include Finite Faucet as part of the project
  • Estimate costs and develop plan to retrofit restrooms in office buildings
  • Identify corporate partners for pilot projects in office buildings

Portable solar LED lanterns

Personal lanternFamily Lantern

As we discussed in class, about 1.3 billion people lack access to grid electricity, and up to 2 billion lack access to reliable electricity.

d.light was founded in 2006 to deliver safe, bright, clean lighting, through both personal LED solar lanterns and micro-grid solutions for homes and businesses. The features below focus on the personal, portable lanterns.


  • The high-efficiency, integrated solar panels enables the d.light S2 and S20 LED lanterns to charge even on cloudy days, and the lanterns are 3x brighter than a kerosene lamp
  • Low-cost: the individual d.light S2 Learning Light is currently $16 on Amazon.com; the d.light S20 Family Lantern is $17.24
  • Both lanterns are portable & lightweight, with at least 4 hours of light when charged (S20 gives up to 8 hours on the lower light setting)

3) Organizational stakeholders: NGOs working in developing nations, homes that lack access to grid electricity, schools, hospitals, etc.

4) Steps to increase deployment:

  1. Reach out to additional NGOs working in developing nations
  2. Partner with US schools that would like to provide students in developing nations with solar lanterns to allow them to learn outside of school/daylight hours
  3. Focus on additional dealers in all nations, as additional sales of the lanterns in developed nations to environmentally-conscious consumers could help fund deployment in other countries

Transforming carbon-rich waste gases and residues into commodity fuel and chemical products


Many industrial processes such as steel production produce high levels of carbon-rich waste gases (including carbon dioxide, carbon monoxide, and methanol), which continue to increase global GHG emissions without some form of carbon capture. Other air pollutants are also generated during these processes.

2) Summary of the technology:

  • LanzaTech is addressing the problem of waste carbon through a new approach to carbon capture and reuse, using a gas-to-liquid technology to produce low-carbon chemicals and fuels that displace petroleum, without the environmental issues of crop- and land-based bioproducts.
  • The process converts carbon-rich wastes and residues produced by industries such as steel manufacturing and oil refining, as well as gases generated by agricultural residues and municipal waste, into commodity fuel and chemical products by using gas fermentation (example – 2,3-Butanediol from steel mill waste gases is a chemical used for the production of nylon and rubber).
  • Carbon-rich waste gas streams enter a fermentation bioreactor, where naturally-occurring microbes consume the gas and grow biomass, producing ethanol as a byproduct. Valuable products are then separated from the fermentation broth – to date, 20 chemicals have been produced, as well as fuel grade bio-ethanol.

3) Organizational stakeholders: Industrial waste managers, product manufacturers that utilize chemicals produced, chemical distributors, fuel companies

4) Steps in deploying this technology:

1) Complete initial proof-of-concept projects utilizing carbon-rich waste gases from different industries

2) Establish relationships with environmental groups and governments to promote carbon capture & reuse

3) Form partnerships with chemical distributors and fuel companies who will purchase products generated through LanzaTech’s process
