A car that doesn't run at all beats an engine that never starts
En La Habana, donde los apagones llegan con la misma certeza que el amanecer y la gasolina ha desaparecido de las calles, los cubanos han comenzado a responder a la escasez no con resignación, sino con invención. Un mecánico ha convertido un viejo Fiat para funcionar con carbón vegetal; otros han adaptado bicicletas con paneles solares para moverse sin combustible. Es una historia tan antigua como la humanidad misma: cuando los sistemas fallan, el ingenio humano busca otro camino.
- Cuba enfrenta una crisis en cascada —sin combustible, sin electricidad estable— provocada por el endurecimiento del embargo estadounidense bajo la administración Trump, que ha cortado el flujo de petróleo hacia la isla.
- Las calles de La Habana han enmudecido de una manera que va más allá del simple inconveniente: la gente no puede moverse, trabajar ni sostener su vida cotidiana.
- Juan Carlos modificó el motor de un Fiat para funcionar con carbón vegetal —más barato y abundante que la gasolina— y sus vecinos, que dudaban, lo vieron funcionar con sus propios ojos.
- Los viejos Cadillac que simbolizaban la resistencia cubana están siendo reemplazados por bicitaxis solares y 'riquimbilis' artesanales que no consumen ningún combustible.
- Los paneles solares no solo mueven bicicletas: también hierven agua en dos minutos para cocinar, desafiando los apagones con la energía del sol.
- Si estas soluciones pueden escalar más allá del ingenio individual y sostenerse en el tiempo sigue siendo una pregunta abierta, pero por ahora demuestran que la crisis no ha dejado a los cubanos sin poder.
En las calles de La Habana, un hombre llamado Juan Carlos ha reconstruido el motor de un viejo Fiat para que funcione con carbón vegetal —no carbón mineral, sino el carbón barato y abundante que se consigue en la isla. Cuando sus vecinos lo ven moverse, no pueden creerlo. "Pensé que no podía ser real", dijo uno de ellos. "Pero lo vi con mis propios ojos."
Cuba atraviesa una crisis en cascada: sin combustible, con apagones que llegan como el amanecer, y con las calles de La Habana en un silencio que habla de algo más profundo que una simple incomodidad. El embargo estadounidense, endurecido bajo la administración Trump, ha cortado el petróleo que antes llegaba a los puertos cubanos. La gente necesita moverse. Necesita trabajar. Necesita vivir.
Así que están inventando. El Fiat de carbón de Juan Carlos no es solo un truco mecánico; es una declaración de supervivencia. La solución, insiste él, no daña el motor de inmediato, funciona, y cuesta menos que la gasolina que ya no existe. Sus vecinos, antes escépticos, se han convertido en testigos de una ingeniería impulsada por la necesidad que se extiende por toda la isla.
Pero la innovación no se detiene en los coches. Los viejos Cadillac americanos que simbolizaban la resistencia cubana están siendo reemplazados por bicitaxis con paneles solares que se recargan mientras circulan por la ciudad. Sin gasolina, sin emisiones, sin angustia por un combustible que no existe. "Esto vale más que un coche moderno en Cuba", dicen los vecinos, y lo dicen en sentido literal y figurado.
Existen también los riquimbilis —vehículos artesanales ensamblados con lo que se pueda rescatar— que no consumen nada. Y los mismos paneles solares que mueven las bicicletas sirven para cocinar: una olla sobre un panel hierve agua en dos minutos, sin factura de luz ni apagón.
Lo que ocurre en Cuba no es una elección. Es adaptación nacida de la desesperación, del entendimiento de que esperar a que llegue el combustible no es una estrategia viable. Si estas soluciones pueden escalar más allá del ingenio individual sigue siendo una pregunta sin respuesta. Pero por ahora, en las calles de La Habana, la gente ve a sus vecinos conducir coches de carbón y pedalear bajo el sol, y empieza a comprender que la crisis, por severa que sea, no los ha dejado sin recursos. Solo los ha obligado a imaginar de otra manera.
On the streets of Havana, a man named Juan Carlos has done something that stops his neighbors in their tracks. He has rebuilt the engine of an old Fiat—a small, ordinary car that has seen better days—to run on charcoal. Not coal. Charcoal. The kind that is cheap and plentiful on the island. When people see it working, they struggle to believe what they're witnessing. "I thought it couldn't be real," one neighbor said after watching it move. "But I just saw it with my own eyes. I was stunned."
Cuba is running on fumes, and not in the way that phrase usually means. The island faces a cascading crisis: no fuel, no electricity, blackouts that come as reliably as sunrise. The American embargo, tightened under Donald Trump's administration, has choked off the oil that once flowed into Cuban ports. With gasoline gone, the rumble of engines has largely vanished from Havana's streets. The city has gone quiet in a way that speaks to something deeper than inconvenience. People need to move. They need to work. They need to live.
So they are inventing. Juan Carlos modified his Fiat's motor to accept charcoal as fuel—a solution he insists won't damage the engine immediately or catastrophically. It works. It's cheaper than gasoline ever was. It's available. His neighbors, initially skeptical, have become witnesses to a kind of necessity-driven engineering that is spreading across the island. The charcoal-powered car represents something more than a mechanical hack; it is a statement about survival, about refusing to be paralyzed by scarcity.
But the innovation doesn't stop with cars. The old American Cadillacs that once symbolized Cuban resilience and style are being replaced by something altogether different: bicitaxis powered by solar panels. These are bicycles retrofitted with seats and solar cells that recharge as they move through the city. No gasoline. No emissions. No stress about fuel that doesn't exist. "This is worth more than a modern car in Cuba," residents say, and they mean it literally and figuratively. A solar bicitaxi represents freedom of movement in a way that a beautiful but immobilized Cadillac cannot.
There are other creations too. The riquimbili—a handmade vehicle assembled piece by piece from whatever materials can be salvaged—consumes nothing. It is pure ingenuity made mobile. And the solar panels that power bicycles are also being pressed into service for cooking. A pot placed on a solar panel will boil water in two minutes. No electricity bill. No blackout. Just the sun doing what it has always done.
What is happening in Cuba is not a choice. It is adaptation born from desperation, from the understanding that waiting for fuel to arrive is not a viable strategy. These are not hobbyists tinkering in garages for fun. These are people who need to get to work, who need to feed their families, who cannot afford to be still. The charcoal car, the solar bike, the handmade riquimbili—they are all expressions of the same impulse: to keep moving when the system that once kept you moving has collapsed.
Whether these solutions can scale beyond individual ingenuity remains an open question. Whether they can sustain themselves over time, whether they can be manufactured reliably enough to serve an entire population—these are the harder problems. But for now, on the streets of Havana, people are watching their neighbors drive cars powered by charcoal and ride bicycles powered by the sun, and they are beginning to understand that the crisis, however severe, has not made them powerless. It has simply forced them to imagine differently.

This is worth more than a modern car in Cuba— Cuban residents, on solar-powered bicitaxis
The Hearth Conversation Another angle on the story
Why charcoal specifically? Why not something else?
Because it's there. Cuba has agricultural waste, wood, things that can be burned down to charcoal. Gasoline has to be imported, and the embargo makes that nearly impossible. Charcoal is local. It's abundant. It works.
But doesn't it damage the engine?
Juan Carlos says not immediately. That's the honest answer—nobody really knows the long-term effects because this is new. But the alternative is a car that doesn't run at all. A broken engine is better than no engine.
What about the solar bikes? Are those actually practical for a whole city?
They're not meant to replace cars for everyone. They're meant to move people short distances without fuel. In a city where gasoline is gone, a solar bicitaxi becomes luxury transportation. It's practical because it has to be.
Do people actually believe these solutions will last?
They don't have to believe they'll last forever. They just have to work long enough to get through the next crisis. That's the real innovation—not the technology, but the mindset that says we'll solve today's problem today and worry about tomorrow when it comes.
Is this what desperation looks like?
No. Desperation is giving up. This is the opposite. This is people refusing to accept that they're stuck.
