As the great Martin Luther King Jr. once said, Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity. How often have you heard that renewable energy sources such as solar power are useless?

The fact is that this couldn't be further from the truth, with renewable energy sources such as solar power making up around 20% of worldwide electricity generation. While the technology certainly isn't perfect and has room to improve, it's moving in the right direction.

An affordable solar-powered car from US-based start-up Aptera Motors is now closer to production.

With new prototype cars now being made, a small, green, suburban three-wheeled vehicle is even closer to production. As announced by Aptera Motors, a start-up in the United States, this production of customer cars is expected to start next year.

There are rumors that the two-seater, the three-wheeled vehicle might come to Australia, but that seems unlikely given the Australian Design Rule (ADR) compliance requirements.

According to its claim, more than 32,000 people have already put down deposits, and Aptera Motors is negotiating its location, finalizing plans for a production facility in Carlsbad, a coastal city south of Los Angeles.

The car has an all-wheel drive system, a drag coefficient of just 0.13, compared with 0.20 for the Tesla Model S, and a lightweight composite body.

Also, the company sells shares by reaching out to potential investors on its website and promising them at least a thousand dollars for their commitment to invest at a ten-dollar and fifty-cent share price.

Earlier this year, an Aptera prototype raced ahead of a Tesla Model 3 during a short drag race in California, as Aptera covers its test work on the car - even though that may not come as a surprise, as the Model 3 variant chosen for the test has a slower 0-100km/h claimed time than the Aptera.
