How is energy used at home in America? We need heat, we need a lot of heat! As of 2009, close to 60% of energy used in American homes heats our water and living space.
What if we could make better use of the heat generated from computation? Instead of solving for the most cost effective computation process vs. heat generation, why don’t we look at the most effective heat generation vs. computation process?
We call it combined heating and computation and we built a prototype.
To promote the concept of Exergy – energy productivity – by exploring energy and its co-benefits. Co-benefits include economic productivity, resource efficiency and adaptability just to name a few.
Technology and Product
We built a high-performance prototype with off-the-shelf components which then used to run Stanford’s Folding@Home distributed computation application. Our prototype generated, captured and thermally stored enough heat to supply space heating for a 1000 square foot apartment. We are currently developing the next prototype with hardware and software that will be ready to plug into HVAC and water heating systems.
- 2006 Beginning of Idea
Lawrence wondered “what use we could get out of a water-cooled computer?”
- 2009 Formation of Concept
Installed radiant hydronic floor heating and ground source heat exchanger at our San Francisco house
- 2012 Summer/Fall First Prototype Build
A 1.5 kW computer with cooling blocks, a storage tank and piping to a radiator and cooler. The prototype provided heat for the 2013 and ’14 winter seasons
- 2014 Spring Spreading our message on line
Our team members start working together towards spreading the Project Exergy message online
- 2015 Winter/Spring
Engage a the crowd to further the design, integration, and application of Henry
- 2016 Second Prototype – Liquid Immersed Model
Fabrication of a 2nd prototype for field demonstration and laboratory performance testing. Secure more funding from R&D grants, crowd funding and other resources.
- 2018 and On…
Design refining and production.
With more than ten years of experience in all aspects of commercial energy efficiency programs – design, management, implementation and marketing – as well as a strong understanding of the Energy Efficiency policy and regulatory environment, Lawrence is well versed in the inner workings of the efficiency industry. Lawrence’s broad industry experience runs the gamut, from field auditing to managing relationships with Fortune 100 utility and corporate clients, affording him a unique ability to draw connections between policy driven utility energy efficiency program requirements and bottom line driven business spending.
Julianna Yun Wei
Engineering and Operations Lead
Julianna is a mechanical engineer with experience in project management and building energy codes and standards research. Her exposure in areas ─ including technical research, policy development, program implementation, and evaluation ─ provides her with a unique perspective that spans across major aspects of energy efficiency. She has led extensive outreach and advocacy activities with industry stakeholders, regulatory agencies and building science researchers. Julianna also dabbled in renewables and worked for a utility-scaled solar PV manufacturer and developer, where she interfaced between the R&D and business departments.
Julianna is a believer in resource efficiency, and is enthralled by the core concept of combining and aligning two important issues of our times – energy and computation. She is ready to help connect the dots between technologies and people through the project.
An agile, test driven approach to software product development (and a sense of humor) has helped John navigate his way around the world a few times. Along the way he continues to learn and refine his craft, focusing on best practice product development, with an emphasis on test driven development and validated learning methodology.
John is a cryptoeconomic advocate, having been an early Bitcoin adopter inspired by block chain technology and a proponent of distributed, decentralized, cryptographically secured peer to peer networks. The synergy between combined heating and computation and distributed computing is of particular interest. John considers it a privilege to work on this project.
Composites Fabricator and Manufacturing Specialist
Chris is a master tradesman with 25 years of prototyping, manufacturing and tooling experience in advance composites. He makes commercial and custom molds and parts based on individual client needs. His work provides support for experimental, aviation, marine, recreational, infrastructure, educational and defense applications. A few example projects from his diverse repertoire include carbon fiber masts for Americas Cup racing yachts, wing parts for Boeing 787s in maintenance repair operations, faux architectural elements for thematic effects, and molds for composites and urethane foams for energy efficient homes. Chris also has management experience in production facilities.
As a master mold maker, Chris creates from plastics, metals, wood, stones and ceramics. He will channel his creative and maker energy to build functional yet aesthetically pleasing prototypes.
Energy Markets and Financial Advisor
Bill is a finance professional with decades of experience in investment banking, structured finance, and environmental markets. Working as a derivatives specialist in Asia, Bill used his creativity and knowledge of financial markets to spot unique and innovative ways to help his customers (large government, state and private counterparties) identify and manage complex financial risks. This knowledge and skill set was subsequently leveraged in the international carbon markets. For seven years, Bill led a team at EcoSecurities tasked with sales, trading and risk management of the largest private sector carbon project portfolio. Bill serves on OneEnergy Renewables’ Advisory Board.
Bill has significant expertise financial structuring, modeling, business development, and negotiation and will bring those skills to bear for LO3 Energy as we look to build partnerships, finance our business and share benefits with stakeholders.
