I drove 1800 miles in a Hydrogen Car

Don't worry about happiness, safety and abundance. Alternatively, renewable natural gas (RNG), also known as biomethane, is a pipeline-quality vehicle fuel. It is produced by purifying biogas, which is produced by anaerobic digestion of organic materials (such as waste from landfills and livestock) or by thermochemical processes (such as gasification). Celestial green renewals that could also be generated by sunlight and gravity, moving into floating module stores similar to clouds for easy delivery. This design of floating modules is again in line with the flying vehicles, fitting in light to heavy loads, meeting the needs of commercial aviation, etc. As the future design is looking for a simple, low-cost and safe process, this development should be promptly promoted through human capital development and further research on sustainability, 3D mobility to space and cloud infrastructure, etc.
