SASSARI — The raw material costs absolutely nothing, and to fill up your tank there’s no need to look for a gas station. All you need to do is drink some water to stimulate your diuretic system and take a break at a rest stop.

Yes, the solution to expensive petrol may be a car that runs on urine.

This actually isn’t a new idea, but a Sardinian researcher named Franco Lisci has developed a way to get around the problems that prevented the use of urine as power until now. His environmentally friendly cars are supported by the University of Sassari and other observers, such as Legambiente — the Italian Environmentalist Association.

Lisci created two types of engines: one for cars and one for domestic use, to power lights as well as water heaters, dishwashers and washing machines.

Among many of his innovations, the formation of condensation and abundance of polluting particles has been avoided by using a special filter: pure sheep’s wool.

On going green (or, well, yellow), Lisci is willing to bet that “the energy produced by the machinery from the urine is not just suitable for domestic use but for engines of cars, trucks and boats and could replace gasoline and other fuels. In Italy this is illegal, but you can use it as an additive,” explains the entrepeneur.

To this end, Lisci has developed transformers that allow the use of urine as an additive in cars that run on other fuels. The results from these tests are more than encouraging. A car that runs on petrol can save 35% with the addition of urine while a car that runs on diesel saves 60% and one that runs on a gas combination can save up to 80%. A boat or trawler could reduce their diesel costs by 65%.”

Savings aside, this proposal also solves the smog problem. “At the end of the process the urine turns into clean water,” says Daniela Ducato, coordinator of the project Casa Verde C02.0 (Green House CO2.0). “This clean water is full of useful substances to nourish the earth.”

The Perfect Paranoia

A synthetic professional observation of the psychological phenomenon driving the anti-vaxxer movement.

Driven not to see

COVID and vaccines can be considered "the perfect paranoia:" The delirium that's swept through those with an internal conflict between the ego and the outside world, just waiting for the right issue to spark their persecutory delusions.
