- Solar power
Solar-powered cars are currently being developed, with the goal of absorbing enough solar energy for long excursions. Fortunately, many of the current solar cars in a development resemble cars rather than flying saucers.
The Lightyear One car, which is a solar-propelled vehicle which can convert the solar energy into electricity as a fuel source, was released in August 2021 by Lightyear, a Dutch automobile manufacturer formed in 2016. The vehicle can drive up to 450 kilometers on a single charge and, happily, resembles ordinary cars on the road today.
Since water is constantly created in our atmosphere, steam is a fantastic renewable energy supply. Unlike the other fuels discussed here, steam has been utilized to power automobiles for over a century. Steam engines, on the other hand, began to lose favor after the introduction of the compact commercial combustion engine.
However, with continuing technological advancements, steam engines may make a comeback. With the development of their cyclone engine, Cyclone Power Technologies, which is an American corporation, has been focusing on reinventing the steam engine for current use.
The most prevalent element in the universe is hydrogen. It can be found in water, air, and biological creatures. Furthermore, it has the potential to be a wonderful fossil fuel replacement in automobiles!
You’ve probably heard about hydrogen fuel cells before. They’re frequently utilized for portable and backup power. The process is a little complicated, but it basically requires an anode and a cathode breaking hydrogen atoms into electrons and protons, which may then be utilized to generate electricity.
Hydrogen-powered vehicles are already on the market, such as Toyota’s Mirai. The Toyota Mirai was introduced in 2015 as the company’s first hydrogen-powered vehicle.
Nitrogen has a wide range of industrial applications, but it can also be used to power a vehicle. Since the first condensation from its gaseous state, there has been a desire to utilize liquid nitrogen as a fuel. This entails converting liquid nitrogen to pressurized gas and driving a piston or even rotary engine with it. Although there isn’t a fully nitrogen-propelled vehicle on the market yet, liquid nitrogen engines are being developed for this purpose. In the 1970s, British inventor Peter Dearman developed a specialized model known as the Dearman engine. Dearman’s son is now putting his father’s idea into action.
Traditional diesel and biodiesel are two totally different entities. While diesel contributes to the release of damaging greenhouse gases into the atmosphere, biodiesel is made from plants. It emits about four times the amount of CO2 per gallon as its non-renewable predecessor.
So, how does it come to be? Take a peek at that vegetable oil bottle in your kitchen. Through a process known as transesterification, animal fats, yellow grease, and cooking oils can all be transformed into biodiesel (with glycerin as a byproduct). To make this alternative fuel, the glycerin is extracted from the oils and fats.
