In this episode, Michael Roche discusses the intersection of financial technology, AI, and the solar industry. Roche shared his background in fintech, particularly in stopping credit card fraud and the evolution of big data and machine learning into Al, including large language models like ChatGPT. They discussed the pervasiveness of Al, data privacy concerns, and the potential for Al to surpass human intelligence. The main topic was Roche's theory of the "energy ledger," a standardized financial record for a home's energy system, akin to a credit score, which he believes is crucial for banks to finance residential solar installations. Roche argued that the solar industry needs to cooperate and standardize, similar to how the financial industry did with credit cards, to enable widespread bank financing of solar systems. They proposed using the podcast as a platform to openly discuss and develop this concept, potentially involving banks, utilities, and inverter manufacturers.   Topics Covered Fintechnology Group www.fintechnologygroup.com Paypal Mafia AI = Artificial Inteligence LLM = Large Language Model Fraud Screening and Authentication Visa and Mastercard Bank AI Plagiarize Books AI Spy Quantum Computing Data Center HeatSpring Credit Score Tax Credit PPA = Power Purchase Agreement FICO Score BIPV = Building Integrated Photovoltaic AVM = Automated Valuation Model DMZ = Demilitarized Zone Everything can be Converted to Energy Energy Consumption of Banks   Reach out to Michael Roche here: LinkedIn: linkedin.com/in/michael-f-roche-b5999a238 Website: www.fintechnologygroup.com Email: [email protected]   Previous Episode: From Fintech to Solar Energy with Michael Roche Link: www.podcasts.apple.com/us/podcast/from-fintech-to-solar-energy-with-michael-roche/id1441958371?i=1000790786948   Learn more at www.solarSEAN.com and be sure to get NABCEP certified by taking Sean’s classes at www.heatspring.com/sean   solarsean.com/intro • solarsean.com/pvip • solarsean.com/pva • solarsean.com/pvds • solarsean.com/esip • solarsean.com/omat • solarsean.com/center • solarsean.com/sfev • solarsean.com/40hrpv • solarsean.com/pv2020nec • solarsean.com/18hrpv • solarsean.com/30hrpv • solarsean.com/ess • solarsean.com/10hress • solarsean.com/pvsiprep • solarsean.com/2hrbfc

This podcast interview featured Sean hosting Tony Alley, an inventor who developed a residential thermal energy storage system using ice. Tony explained that his technology addresses the need for cost-effective energy storage behind the meter, particularly for California residents, by using water as the storage medium instead of expensive battery systems. He described how his design can store enough cooling for an average house for 10 hours using a relatively small 3x3x3 foot block of ice, compared to the much larger tanks required for chilled water storage. Tony emphasized that thermal energy storage has been around for over 100 years in industrial applications but hasn't been successfully adapted for residential use due to challenges in getting both cold in and out of the system economically. He noted that his design is reversible for both heating and cooling, uses tap water as the storage medium, and can be installed as a box-like unit on the side of a house. Tony is currently seeking funding through the National Science Foundation to develop prototypes and bring the technology to market within a few years.   Topics Covered Ice Power Energy icepowerenergy.com Thermal energy storage Residential ice storage Patent process & inventor challenges Patent trolls Solar energy storage Grid infrastructure BTU = British Thermal Unit NSF = National Science Foundation Chilled water grids Radiant ceiling cooling Battery cost comparison Wright brothers’ story Solar industry growth   Reach out to Tony Alley here: LinkedIn: www.linkedin.com/in/tony-alley Website: icepowerenergy.com Email: [email protected]   Podcast with Jack West Inventor Apple Podcast YouTube Spotify Pandora Podbean   Learn more at www.solarSEAN.com and be sure to get NABCEP certified by taking Sean’s classes at www.heatspring.com/sean   solarsean.com/intro • solarsean.com/pvip • solarsean.com/pva • solarsean.com/pvds • solarsean.com/esip • solarsean.com/omat • solarsean.com/center • solarsean.com/sfev • solarsean.com/40hrpv • solarsean.com/pv2020nec • solarsean.com/18hrpv • solarsean.com/30hrpv • solarsean.com/ess • solarsean.com/10hress • solarsean.com/pvsiprep • solarsean.com/2hrbfc

In this podcast, Eli Paster, CEO of Polyjoule, discussed polymer-based battery technology and how it differs from conventional metal-based batteries. Eli explained that Polyjoule uses conductive polymers instead of lithium, nickel, cobalt, lead, or sodium, synthesizing its own conductive polymers from abundant hydrocarbon feedstocks. Eli detailed the safety advantages of polymer-based batteries, including the inability to enter thermal runaway, and demonstrated this by cutting open a cell and applying a blowtorch for five minutes with no fire. Sean and Eli explored potential applications in residential energy storage, building codes, and the possibility of Polyjoule batteries being rated as firewalls.   Topics Covered: Polymer-Based Battery Conductive Polymers Hydrocarbon Feedstock Monomers and Polymers Polyacetylene PVC = Polyvinyl Chloride Lithium-Ion Battery LFP = Lithium Iron Phosphate NMC = Lithium Nickel Manganese Cobalt Oxide NCA = Lithium Nickel Cobalt Aluminum Oxide Sodium-Ion Battery Solid-State Battery Lead Acid Battery Thermal Runaway Short Circuit Arc Flash Battery Separator Electrochemistry Anode and Cathode Electrolyte Prismatic Cells Depth of Discharge Nominal Voltage Energy Density Round Trip Efficiency Schneider Electric UPS = Uninterruptible Power Supply UL 1973 UL 9540A IRC = International Residential Code NEC = National Electrical Code EV Auxiliary Battery Hybrid Battery Systems Hydrogen Fuel Cells   Reach out to Eli Paster here: LinkedIn: www.linkedin.com/in/elipaster Website: www.polyjoule.com Email: [email protected]   Learn more at www.solarSEAN.com and be sure to get NABCEP certified by taking Sean’s classes at www.heatspring.com/sean   solarsean.com/intro • solarsean.com/pvip • solarsean.com/pva • solarsean.com/pvds • solarsean.com/esip • solarsean.com/omat • solarsean.com/center • solarsean.com/sfev • solarsean.com/40hrpv • solarsean.com/pv2020nec • solarsean.com/18hrpv • solarsean.com/30hrpv • solarsean.com/ess • solarsean.com/10hress • solarsean.com/pvsiprep • solarsean.com/2hrbfc
