Multi-engine clean energy

Leave more than footprints.

Travel usually ends as a memory. ZEV City is designed to turn part of that spending into real clean energy in the place you once loved.

A New Kind of Keepsake

A souvenir that never gathers dust.

Not a magnet. Not a postcard. A living piece of energy in the place you once loved.

That makes the emotional logic of travel visible first, before we explain the bigger system underneath it.

Travel is where memory and infrastructure can finally meet.

The Model

Three footprint sectors. One clean energy system.

ZEV City starts with travel, then expands into other major footprint sectors. The chart below uses a developed-market household footprint framing, so the early target countries are a better fit than using a global average.

Daily life footprint sectors
Travel

About 26%. Transport and travel in developed-market household footprint studies. Engine 1 starts here.

Buildings

About 28%. Housing, home energy, and building use in developed-market household footprint studies. Engine 2 expands into this sector.

AI / Compute

About 18%. Food systems are one of the largest household-linked footprint categories today. ZEV City does not start here, but it shows how large everyday consumption categories can be.

Other sectors

About 28%. Goods, services, and the rest. ZEV City does not need to solve everything at once. It focuses first on the biggest everyday categories where value can be reclaimed and redirected.

Working source basis for this review version: developed-market household footprint framing, aligned to OECD / UN-style consumption categories such as transport, housing, food, and other goods & services. Exact citation line can be tightened in the next pass once we lock the final source table.

Why place travel first? Because travel is emotional, visible, and easier to narrate than most consumption categories. It is not necessarily the single biggest slice, but it may be the best entry point for turning footprint into participation.

Engine 1

Travel

Human mobility creates a major share of personal carbon footprint. ZEV City uses travel margin to route that value into local clean energy allocation.

Move Travel margin Local energy zTokens
Engine 2

Buildings

Home and office energy use creates another major footprint sector. Plug-in solar and building-linked energy data let ZEV City route indoor energy value into a verifiable clean energy network.

Future Engine

AI / Compute

AI compute is becoming a new footprint sector outside the classic household breakdown. ZEV City is designed to add AI routing later, extending the same logic beyond the current developed-market consumption categories.

Use AI Compute margin Renewables zTokens

Why this structure? ZEV City is designed to start from one emotionally resonant category, travel, then expand into other large everyday footprint sectors and eventually new ones like AI. Travel opens the story. Buildings deepen the system. AI extends the model.

Engine 1: Travel

Every trip funds energy where you visit

Book trains, EVs, hotels, and flights through ZEV City. The goal is price parity with major platforms, while net margin is redirected into local clean energy allocation.

1

Book Low-Carbon Travel

Search and book through ZEV City. We aim to match normal market pricing while earning standard affiliate commissions from OTA partners (Trip.com, Agoda, and others).

2

Commission → Local Energy

Net commission is allocated to clean energy projects in the destination country. London hotel → UK solar. Tokyo flight → Japan renewables.

3

Energy Is Tokenized

Each £1 allocated creates 1 zToken, an energy-linked token representing verified participation in real infrastructure allocation. Not a loyalty point. Not a carbon credit.

4

Tokens Flow Back

In Phase 1, 80% of tokens go to users and 20% to the team. In later phases, governance may activate broader airdrop distribution. Team participation remains token-based, not cash-based.

Commission Rates (via ZEV UK)

Hotel 4.4% Car 3.6% Train 1.4% Flight 0.8% EV Lease £80

These rates define the pool from which net clean-energy allocation is calculated. Pricing is intended to remain competitive with direct and OTA channels, but may vary by inventory and market.

Engine 2: Solar Mining

Your balcony is your mining rig

Your balcony has been wasting sunshine for years. Every morning, light hits your railing, warms your coffee cup, and disappears. What if that same sunshine powered your home, earned you tokens, and connected you to thousands of other balconies doing the same thing? One panel. One plug. You're part of something.

1

Buy a Plug-in Solar Panel

Purchase through ZEV City at standard market pricing where possible. Works with Hoymiles, Deye, and other major brands with WiFi-enabled inverters.

2

Connect Your Inverter API

Link your inverter's cloud account to the ZEV City dashboard. Generation data flows automatically — no manual input needed.

3

Mine zTokens with Sunshine

Every month you maintain active data (≥25 days), you earn zTokens. A $300 panel earns 12–24 tokens over 3 years, depending on phase.

4

Join the Energy Network

Your panel becomes part of a verified, decentralised energy portfolio. 500 balcony nodes in Bavaria = a real, measurable clean energy project.

Buy from a competitor

  • Pay $300 for a solar panel
  • Save on electricity
  • That's it

Buy from ZEV City

  • Pay $300 — same panel, same savings
  • Earn 12–24 zTokens over 3 years
  • Airdrop eligibility (wholesaler phase)
  • Verified energy network membership
  • Performance-based purchase discounts

Same hardware category, with added tokenized participation through ZEV City. Value depends on margin, phase, and verified data continuity.

Solar Mining Economics

The numbers behind solar mining

ZEV City treats each solar sale as a fixed-term micro energy project. Revenue is captured at point of sale — not dependent on actual generation.

Affiliate Phase (5% commission)

Panel: $300 · Commission: $15

Mint: 15 zTokens

User: 12 tokens (80%) over 3 years

= 0.33 zTokens/month

Wholesaler Phase (20% margin)

Panel: $300 · Margin: $60

Mint: 60 zTokens

User: 24 (40%) · Airdrop: 24 (40%) · Team: 12 (20%)

= 0.67 zTokens/month + weekly airdrops

Each sale is registered on-chain as a 3-year micro energy project. Users earn monthly mining rewards by maintaining active data uploads. ZEV City cash flow is positive from day one — zero subsidies, zero additional capital required.

Why This Is Different

Participation, not offsets

You don't want to offset your guilt. You want to mean something to a place.

Carbon offsets are a transaction. You pay, you forget, nothing changes in your life. ZEV City is different — every trip becomes an ongoing relationship between you and a place. You visited. You invested. And every month, you see proof that your energy is still flowing. That's not sustainability theatre. That's belonging.

Traditional Carbon Offsets

  • Abstract, unverifiable claims
  • Money disappears into opaque projects
  • No ongoing participation or verifiable allocation
  • "Guilt tax" that changes nothing
  • AI cannot verify impact

ZEV City Dual Engine

  • On-chain, machine-auditable proof
  • Direct investment in named projects
  • Tokenized participation with verifiable allocation rules
  • Live energy data from solar mining nodes
  • AI agents can independently verify

Token Economics

Community-Governed Distribution

Token distribution evolves with the ecosystem — and the community decides when to unlock the most powerful feature.

Phase 1 (Affiliate) — Early Stage

80%
To the user
20%
ZEV City team

Phase 2 (After Community Vote) — Full Ecosystem

40%
To the user
who booked or purchased
40%
Airdrop pool
shared weekly with all holders
20%
ZEV City team
tokens, not cash — aligned

The airdrop pool isn’t a company decision — it’s a community vote. Phase 2 starts at 40:60 (user:team). Token holders vote to choose between keeping 40:60 or activating the airdrop pool (40:40:20). No pre-mine. No ICO. Every token backed by real energy investment.

Why 40% > 80% in practice

Phase 2 means ZEV City has become a full OTA (10–15% commission) instead of an affiliate (3–5%). For an £800 hotel: Phase 1 = 80% of £35 = 28 zGBP. Phase 2 = 40% of £96 = 38 zGBP. Users earn more tokens per booking despite a lower percentage.

zTokens — Regional Energy Tokens

Each country has its own zToken denomination target. Both engines are designed to mint into the same regional token pools. Today, the live on-chain deployment is still a Sepolia prototype, not a production mainnet asset.

zGBP £1 TESTNET PROTOTYPE zEUR €1 SOLAR PRIORITY zUSD $1 zTWD NT$1 zJPY ¥1

Community Governance

Token holders govern two critical decisions: which energy projects get funded and whether to activate the airdrop pool. The smart contract includes an airdropEnabled boolean from day one — the community votes to choose between Option A (40:60 user:team) or Option B (40:40:20 with airdrop). Solar miners get data-weighted voting power. Because your token reward is fixed by purchase amount, you’re free to choose social impact over financial returns with no penalty.

Transparency

Energy Balance Sheet

A fair comparison: energy consumed (by travel) vs. energy produced (by our projects + solar mining network).

kWh Consumed
by travel booked
kWh Produced
projects + solar nodes
Net Balance

This balance sheet is still under construction. Solar mining node data and project-level energy records will populate it once the new contract and data pipeline are live.

Verify Our Claims

Smart contracts define what is verifiable today, and what is being upgraded next

The current on-chain deployment is a Sepolia prototype for the earlier travel-first design. It is verifiable today, but it is not yet the final multi-engine v3 architecture.

The Flywheel

4 self-reinforcing loops

Energy Loop

Both engines invest in clean energy → cleaner grid → greener travel options → more users → more energy.

Reward Loop

Every transaction (travel or solar) mints tokens + feeds airdrop → stronger incentives → more participants.

Impact Loop

Token holders vote on community projects → greater impact → stronger stories → more attention → more users.

Data Loop

Solar nodes provide real-time generation data → stronger proof of impact → better AI evaluations → more trust → more users + nodes. This is the proof layer that lets the system expand toward a multi-engine model.

Travel provides capital. Solar provides data. Neither alone creates a complete ecosystem. Together, they define the target system ZEV City is now aligning into one verifiable architecture.
