# Two markets, one machine.

Nearly half the energy on earth goes to making heat.[1] Data centers are set to double their electricity use by 2030.[2] One market pays to make heat. The other pays to get rid of it. We sell them the same machine.

*Why now*

## The world is ready and waiting for computationally generated heat.

### The hardware arrived

The product is now possible. Current compute hardware can output roughly 180°F, hot enough for hydronic comfort and process heat.

### Decarbonization pays

Households get a reason to leave gas. An electric heater that earns gives them one, and can replace recently repealed solar incentives.

### The grid wants it

Capacity is no longer the obstacle. New homes have more electrical capacity than ever, and networked equipment responds to grid conditions.

### The cloud goes local

Smaller wins on timing. Distributed compute is on the rise, and smaller deployments are less risky and faster to market than a data center.

*Our advantage*

### IP and trademarks

**Patent**: Patent pending, with broad utility.
**Brand**: Heatoshi®
**Tagline**: Have Fun Staying Warm™

### Safe, clean, efficient

**Safety**: Safer than fossil-fuel heating.
**Clean**: Cleaner than fossil-fuel heating.
**Efficiency**: Efficient on its own. Pair it with heat pumps or solar for more.

### Our competition

**Gas boiler**: Low cost, low efficiency, no reward.
**Heat pump**: High cost, high efficiency, no reward.
**Heatoshi**: Subsidized cost, high efficiency, significant reward.
