Cactus juice being used to make fuel
As more attention is being paid to global warming and climate change, new fuel ideas have to be introduced. One Mexican company is turning to prickly pear cactus to produce biofuel. Aptly named “the green gold of Mexico”, the cactus is first pureed and mixed with manure. The mixture is then left to decompose, producing methane in the process. Since 2015, the fuel has been used on a machine called the biodigestor but is now being tested on government vehicles. As long as the cactus is regularly replanted, this process will remain sustainable. The water and waste produced is used to fertilise crops. The fuel is a third cheaper than normal fuel and is believed to last longer. Surely, with the right innovations, fuel will no longer be expensive.
Smart freeway to be completed by 2022
China’s first smart freeway is set to be completed in 2022. It is meant to support self driving cars so it will be embedded with driving sensors and photovoltaic cells. Warning systems are also built into the system, using the internet of vehicles to avoid accidents. The 6 lane, 161 km freeway will link Hangzhou with Ningbo. The journey which normally takes 2 hours will be reduced to just 1 hour. Self-driving cars are coming soon. This is a sign.
Countries using 100% renewable energy
Four countries, Iceland, Paraguay, Norway and Costa Rica run nearly 100% on renewable energy. Iceland generate most of its power from geothermal energy and hydropower also plays a key role. In Paraguay, most of the power comes from hydroelectric projects. They actually often have a power surplus. Since the 1800s, Norway has used hydropower to generate energy. Wind power usage is on the increase. Hydropower is also a major source in Costa Rica although geothermal and wind are also used. Brazil is 75% reliant on renewable energy while Denmark is on 69.4%. 100% renewable surely is feasible and sustainable.
China’s parking solution
Parking problems are increasing the world over. More and more land owners prefer to build properties rather than use the land to build parking spaces. In Shanghai, the first vertical circular garage was recently built. It can accommodate 20 cars in a space that normally would fit only 2 cars. It’s like many floors for cars. This is certainly one to be replicated around the world. You just have to see it to understand how it works.
