What Salto does not have yet.
Twenty-five things that do not exist and make more sense here than anywhere else, because the hot water, the sun, the fruit, the border and the university are already in place. Each one says what is missing. They are my own proposals, written for someone to take.

From the hot springs
-
01
A tropical garden under glass
Salto's hot-spring water comes out at between 38 and 46 degrees, according to Uruguay's thermal-water Vademécum, and leaves the pools still warm, straight to the river. That return heat can keep a glasshouse going, glass rather than plastic: a tropical garden of palms, orchids and fruit trees from another climate, enclosed and at 25 degrees in the middle of July, one more attraction of the springs rather than a farm plot beside them. Big cities have their palm houses; here the heat would come from the well, burning nothing.

02
A skincare line made with Salto's water
Vichy, Avène and La Roche-Posay are villages with a spring and a brand. Salto has the water, the analysis (Uruguay's thermal-water Vademécum describes it) and not a single cream with its name on it. What is missing is the lab and the packaging; the argument is already written.
-
03
Warm-water fish farming
The water leaving the pools holds an even temperature all year: what a tilapia farm pays for in energy, here the well provides. Fish farming next to the springs, with the fish on the tables of the restaurants around them.
-
04
A coworking space a hundred metres from the pool
Remote workers choose where to live, and Salto can compete on price, hot-spring water and fibre. What is missing is the place: desks, meeting rooms and monthly lodging at Daymán, priced for Argentines and Brazilians who stay for weeks rather than weekends.

From the land and the fruit
-
05
A freezing plant for strawberries and blueberries
At the peak of the harvest the price collapses under oversupply, and the price analysis shows it year after year. Freezing the fruit that has no buyer that week and selling it all year, instead of dumping it, is what fruit regions that have been through this already do.
-
06
Essential oil and pectin from citrus peel
Salto exports citrus at scale and the peel is worth money: orange and mandarin essential oil for perfumery and food, pectin for industry. Today those by-products leave the country inside the whole fruit or go to waste at the juice plant.
-
07
A geographical indication for Salto's mandarins
Uruguay has had the law and the register for years and not a single food product on it: Colonia cheese only started down that road in June 2026. Export mandarins do not need it, because they sell by patented variety under the exporter's brand. Where it would add value is the small mandarin and the juice for the home market, and across the river, now that Argentina recognises Mercosur geographical indications and "Salto" means something there. What is missing is not the law: it is a growers' association to apply for it and agree on the rules. The scale is already there in the prices since 2011.
-
08
Parametric insurance for greenhouses
The storm of 18 July 2026 damaged some 150 hectares of greenhouses and hit around 300 growers. A policy that pays out on wind measured at a weather station, with no loss adjuster, would pay within days. What is missing is the insurer to design it and the open-data station to trigger it.
-
09
What the city throws away, back to the land
A city of 125,000 people and a market-garden belt ten kilometres out: municipal compost from organic waste, delivered to the farms instead of buried. The logistics already exist at the Central Hortícola del Norte; what is missing is the plant and separate collection.

From the border
-
10
A Salto–Concordia pass
Two cities, two sets of hot springs, one river and fifteen minutes across the dam. A single ticket for the springs, the museums and the buses on both banks, priced in each side's pesos. Today each city sells itself alone, and the visitor picks one.
-
11
A timetable, a ticket and a connection for the boat
The boat has crossed the river since before most people can remember: the Don Demetrio, run by the Sancristóbal family, ten minutes bank to bank. What it lacks is a published timetable, a ticket bought from a phone and a bus waiting on the Concordia side. With that, the loveliest crossing on the border would stop being a local secret.
-
12
Both banks' prices in one place
Petrol with the border discount on this side, the blue dollar on the other; whoever crosses does the sums by hand. A binational board (fuel, exchange, tickets, groceries) that updates itself. The Salto half is already published in Live in Salto.

From the sun and the grid
-
13
Charging the car on the street, overnight
On UTE's overnight tariff, 100 km in an electric car cost several times less than on petrol: the sums are done. Whoever has no garage cannot use it. Slow chargers on the kerbs of streets without driveways, on that tariff, in the sunniest city in the country.
-
14
Electric taxis on the official fare
The official meter fare is the same for every taxi; the cost per kilometre is not. An electric fleet charged overnight keeps the difference on every ride to the hot springs and the airport. What is missing is the finance for the car and chargers at the rank.
-
15
Solar drying at the peak of the harvest
The highest solar irradiation in the country falls on the area that grows the most tomatoes. Solar dryers for tomatoes, citrus peel and strawberries in the weeks of oversupply: a shelf product made with the sun that is already there and the fruit that finds no buyer today.
-
16
Solar panels on the Central Hortícola
The Central Hortícola del Norte has 75 stalls, cold chambers that draw power all day and a huge roof under the best sun in the country. Panels on that roof would cut the refrigeration bill exactly when it bites hardest, at summer midday, and the Central's public-private board can sign it off. The large-scale energy case is in Invest in Salto; this is the small one, in full view of every grower.

From the university and the airfield
-
17
Drones for the farm
A flight school, a degree in control and automation engineering and more than 780 growers in the same department. A drone service to look at greenhouses and citrus from above, with pilots trained here rather than hired from Montevideo.
-
18
A farm-data lab
The prices are open, month by month since 2011, in the observatory. What is missing is a course or a lab that uses them: price forecasting, oversupply alerts, with the data and artificial intelligence engineering taught ten blocks from the market.
-
19
Sensors in the well, the river and the greenhouse
River level, well temperature, greenhouse humidity: a network of cheap sensors published as open data, maintained by the water-resources degree. It is what the parametric insurance above needs, and what nobody measures continuously today.
-

A technology park next to the Central Hortícola
Salto does not yet have a working industrial park: the Altos del Uruguay one has been a project for more than twenty years. The Central Hortícola del Norte was built on a site of about 90 hectares, at Routes 3 and 31, set aside for a future agrifood and logistics park. The idea is for that park to be born a science and technology park too: software, data and automation companies next to the Central, with Udelar, which teaches those degrees a few blocks away, and the aerospace policy the country announced in September 2026. COMAP gives projects located in science and technology parks 15% more benefit and time, plus a credit on the employer contributions of the new jobs. The incentive exists and so does the site; the park is what is missing.

21
A bilingual immersion school
Salto has schools with strong English: the strongest, Crandon Salto, offers eight hours a week and Cambridge certificates. What it lacks, and Concordia too, is an immersion school, where half the day runs in another language from pre-school, as several do in Montevideo. It is the first question any family asks before moving for Salto Grande, the solar farm, the university or remote work, and today the answer decides against. With Concordia fifteen minutes away, the same school would serve families on both banks, and Portuguese is the obvious third language three hours from Brazil. What is taught in Salto today is in Study in Salto.

From the city and the river
-
22
A literary festival for the river country
Horacio Quiroga, Enrique Amorim and Marosa di Giorgio were born in the same city. A festival that brings them together, with readings at Las Nubes, Amorim's house, and panels on the riverbank, would carry a name no other city in the country can use.
-
23
The buses in real time
The map of the 12 lines is already on this platform: the route street by street and an estimated passing time at every corner, worked out from the departures at each terminus. What is missing is what makes any transit app useful: a GPS on each bus saying where it is right now, and with it the real time at every stop. A GTFS file published by the Intendencia, with live positions, would put Salto on Google Maps and in any app without writing a line of code.
-
24
Beds for peak dates
When Pope Leo XIV visits Paysandú on 7 November 2026, Salto takes the overflow, as the piece on the visit explains (in Spanish). A registered pool of beds in private homes, with published prices, for the weekends the hotels cannot cover and that today get sorted out over WhatsApp.
-
25
A public API for Salto
Everything this platform publishes (the river, the weather, the power, the agenda, the prices) as an API with a timestamp, so anyone can build an app without asking. It is the next step here, and the only idea on the list that already has an owner.

How to read this list
This is not a plan or a list of projects under way. These are my own proposals, subjective ones, written from the data and from outside the sector: I may be wrong about any of them, and some may already exist or have been tried. I chose them because they make more sense in Salto than elsewhere, because what makes them possible is already here: the hot-spring water, the sun, the fruit, the border, the university, the river. Each idea says what is missing, which is almost always less than it looks.
The data behind them lives in the rest of this platform, with sources: the price analysis, the prices since 2011, the Central Hortícola, the cost of 100 km. The ideas carry no source because they are not data: they are what comes out of crossing it.
If one of them already exists, or you are building it, write to me: I take it off the list, or I tell the story.
They drilled for oil and found hot water. Arapey, 1941. Daymán, 1957.
Salto's greatest find was an accident. The next ones do not have to be.
What comes next
An idea that is not here
If you have one and want to see it on this list, with your name or without it, send it. And if you want the department's full investment case, it is in Invest in Salto.
