Cars of the 21st century are emitting less and less pollution.Despite this, fossil fuel burning is still necessary to power the car and thus emit pollution.With the technology that we have today, it is impossible to have 0 emissions while burning fossil fuels.But alternatively,
Vehicle propulsion systems are the integration of energy storage (diesel, gasoline, batteries etc) with energy transformation (chemical to mechanical, chemical to electrical to mechanical, etc) systems. For an electric (core technology) based vehicles, electric storage in batteries has been limiting.
With over 50 years of development and literally tens of thousands of testers, roller coaster rail system technology has more than proven itself as a transportation technology. However, it has never been transitioned into use by a commercial or public sector transportation system.
People and sensitive electronics traveling in space need protection from high energy radiation. Solid shielding materials are very dense.
I assume that a very small proportion of particles strike the craft at a right angle. My idea is to make some walls, bulkheads, floors,
This system works as a straw. When you put the finger at the straw’s upper end, the liquid does not drop because of the air pressure. Fig 1 presents the system at quiet state. We organize the set so it takes the lesser space on board.
