Electric Vehicles

Why are people getting bigger vehicles? It makes no sense.

Efficiency and recycling has already reduced the need for mining raw materials for EV batteries. With the right policies, it might be possible to reach a fully circular battery economy with no need for further mining.

So it might be the fleet of EVs could be created with less mining less material than just one years worth of fuel fossil fuels for transportation

Doing things like mining asteroids and being able to create and clear space junk aka satellites are exciting prospects, but getting into space is dirty business. So how about we remove that dirty and expensive step by simply installing an elevator that takes us outside of the atmosphere and essentially cuts the cost down to be negligible.

I asked Gemini and it said this:

Space elevators are a theoretical concept for a megastructure that would provide a permanent connection between Earth's surface and space. While there are significant engineering challenges to overcome, the idea remains an exciting possibility for the future of space exploration. Here's a simplified breakdown of how a space elevator might work:

• A massive cable, made of a yet-to-be-developed ultra-strong material, would be anchored to the equator and extend tens of thousands of kilometers into space.
• A counterweight at the far end of the cable would balance the structure and keep the cable taut.
• Earth's rotation would generate centrifugal force, counteracting gravity and keeping the cable upright.
• Vehicles or climbers would ascend and descend the cable, transporting cargo and people into space. The potential benefits of space elevators are numerous:
• Drastically reduced launch costs compared to traditional rockets.
• Easier and more frequent access to space for scientific research and tourism.
• Potential for revolutionizing space-based solar power generation.

However, there are significant challenges that need to be addressed before space elevators become a reality.

• The development of a material with sufficient strength-to-weight ratio to construct the cable.
• Maintaining the cable's integrity in the harsh space environment.
• The enormous financial and engineering resources required for construction.

Despite these challenges, space elevators remain an intriguing possibility for the future. Research into advanced materials and engineering techniques continues, and one day, they may become a reality.

Am I the only one that thinks Scaringe looks like Steve-O?
