Ovenbird

Our buyers are plant managers and the finance people above them. They hear “climate tech” and file us under science project. We need them to see a boiler they can schedule, with a business case, not a climate pitch.

Plant people trust what they can see working, and they buy uptime before they buy carbon. The site has to look like it was made for the boiler room. It has to show the system working on their plant’s day, not on an abstract planet.

An ovenbird builds its nest out of clay: a small oven that holds warmth long after the sun goes. Ovenbird does the same thing at factory scale. So the whole page runs on one 24-hour clock. The core charges while power is cheap and delivers while the plant works.

In the live concept

The concept is one long homepage. Everything below is in it, and you can try it in the frame above.

• The hero (#plant). The headline “Steam on schedule.” sits over the 24-hour plant, with a site-assessment button and a “How it works” link.
• The 24-hour plant (#ring, #controls). A code-drawn core sits inside a 24-hour ring, with steam lines running out to a simple plant outline. Details under Signature interaction.
• Three plain answers (#answers). What it replaces, where it fits, and who maintains it. Each answer has a small drawn figure, one of them a maintenance calendar.
• How it works (#how, #cut, #parts). A labelled side cutaway with four numbered parts: heating elements, storage core, insulation, steam generator. Pick a part from the list or the drawing, and its short explanation opens while its number lights amber in the drawing.
• Two readers, one machine (#readers). Two columns on the same page. For plant managers: a six-point site checklist covering loads, steam tie-in, grid connection, controls, maintenance and faults. For finance: the business-case method (inputs, assumptions, sensitivities) and a sample-data chart of which inputs move the case most. It shows no promised numbers.
• Reserved slots (#standards). One empty slot for customer proof and three for safety certifications, all marked “supplied by client”. We never fill these in ourselves.
• Site assessment, step one (#assess, #assessForm). Steam load, delivery pressure, operating hours and tariff structure. Three of the four fields arrive already filled from the 24-hour plant and are marked “carried”. A three-step indicator shows what comes next.

Designed, not built in the concept

• We specified a separate How it works page, with a two-sentence explanation of each part written for a site engineer. The concept puts this on the homepage.
• We specified a printable For plant managers page and a For finance page. In the concept these are one section, and their links stay on the homepage.
• We specified a Safety & standards page. The concept has its reserved certification slots and nothing more.
• We specified steps two and three of the site assessment (your site, then you). The concept builds step one. “Continue” moves the step indicator and sends nothing.

Try it in the frame above. Scroll, or drag the hand around the ring, to move through a day. Overnight the core charges and glows deeper as cheap power comes in. At shift start, steam lines draw out to the plant. The clock, the core’s charge and temperature, the grid draw and the steam rate all follow the hour.

Set your own steam demand, operating hours and tariff shape (flat, day/night or dynamic), and the charge and delivery pattern redraws around them. A line under the ring sums up the day. It is labelled “Illustration, not a quote”, and your inputs carry straight into the site-assessment form.

With the keyboard, focus the ring and use the arrow keys. Under reduced motion the same diagram and inputs stay, and it redraws on change without animating.

These are the concept’s colours, not Vivid’s.

Role	Name	Hex
Ground (dark)	Graphite	#17191C
Ground (light) / panels	Refractory	#E4DCCF
Core heat, the one hot colour	Ember Amber	#F28A1E
Steam / delivery lines	Steam	#A9CFDB
Structure, rules, secondary text	Steel	#7F8A91
Warning / fault states only	Signal Red	#C7361F

Type: Archivo, using its width axis: Expanded for headlines and part labels, Normal for body. It is paired with JetBrains Mono for readouts, the clock ring and form inputs. Both are open-licence fonts, served from the concept itself.

Mood: heavy, warm, engineered. Callouts are drawn like engineering drawings, with leader lines, mono labels and part numbers. There are no leaves, no globes and no green-for-good.

After one visit, a plant engineer should be able to explain to their own boss how Ovenbird would sit in their plant. The site assessment should arrive already holding the numbers a sales engineer would otherwise spend the first call collecting.

Figures inside the concept are sample data. Ovenbird is a fictional brand.
