Manas Choudhary · Delhi, India

At the intersection of Markets, Startups, and Frontier Engineering.

Mechanical engineer and ISB Merit Scholar bridging applied engineering research and physical systems with techno-economics, market adoption, and frontier venture diligence across clean fuels, climate systems, and industrials.

Core Framing

Three Lenses of Exploration

How physics, market mechanics, and venture building inform every thesis.

markets

Markets

Techno-economics, adoption curves & energy transition

Analyzing unit economics, infrastructure capital expenditure, regulatory forcing functions, and adoption curves across clean energy carriers, electric mobility, and industrial transitions.

Guiding Inquiries

  • •Where does the economic bottleneck sit along the physical supply chain?
  • •What is the true lifecycle total cost of ownership (TCO) vs legacy incumbents?
  • •How do regulatory inflection points (EUDR, carbon pricing, subsidies) alter market equilibria?
Techno-EconomicsHydrogen LogisticsEV AdoptionPolicy ModelingInfrastructure
startups

Startups

Venture diligence, commercialization & technical defensibility

Evaluating early-stage frontier technologies, stress-testing whether laboratory breakthroughs survive manufacturing scaling, and advising founders on go-to-market and investor positioning.

Guiding Inquiries

  • •Is the primary risk fundamental physics or manufacturing engineering?
  • •Does the product deliver unit-cost parity without relying on permanent subsidies?
  • •What is the customer acquisition wedge and real deployment friction on the factory floor?

Frontier Engineering

Applied physics, remote sensing & autonomous hardware systems

Grounding market theses in quantitative engineering—from satellite foundation model embeddings for regulatory ESG proof to multi-criteria robotics optimization and high-energy directed systems.

Guiding Inquiries

  • •How do thermodynamic and sensor resolution limits constrain real-world performance?
  • •Can multi-modal foundation models replace noisy heuristic computer vision pipelines?
  • •How does software flexibility on the plant floor outrank upfront equipment Capex?

Dictate: Local-First macOS Dictation & Context-Aware Speech Engine

A local-first, context-aware speech-to-text dictation application for macOS running speech recognition and formatting entirely on-device via whisper.cpp. Users hold a global hotkey, speak naturally, and cleanly structured text appears directly at their active cursor without audio frames ever leaving their computer.

Core Insight: Achieves sub-150ms latency with <35 MB idle RAM footprint on Apple Silicon, eliminating $15–$30/month cloud subscription fees and latency while guaranteeing complete air-gapped privacy in airplane mode.

Plot Passport: Satellite EUDR Verification Engine

A plot-level satellite verification system designed to help agricultural commodity exporters prove deforestation-free provenance under the strict EU Deforestation Regulation (EUDR) cutoff date.

Core Insight: Achieved 1.00 recall vs 0.23 recall against standard FAO Whisp baselines on dense tropical smallholder plots.

Fuel Cell Vehicles: Techno-Economic & Infrastructure Feasibility

A quantitative review comparing proton-exchange membrane fuel cell vehicles (PEMFCs) against battery electric vehicles (BEVs) and internal combustion engines across lifecycle total cost of ownership.

Core Insight: Demonstrated that fuel cell commercial viability is constrained by midstream distribution and dispensing Capex (over 58% of fuel cost), not stack efficiency.

Domain Adaptation

Custom Vocabulary & Phonetic Biasing

Provide phonetic biasing tokens for uncommon engineering terms, repo names, acronyms, and teammate names.

Active On-Device Phonetic Biasing Tokens:
