How would a turbine that takes energy from the air current generated by a passing car decrease the energy of the car?
Not sure where you got that idea from, but how would that generate a meaningful amount of energy? It seems very unlikely that such a system would ever recover the energy spent on its construction.
Sure, but those are completely different approaches. Dams have the advantage that they have a much larger capture area for water and that they can accelerate the water beyond the 10 m/s terminal velocity of raindrops.
Raindrop energy harvesting is a rubbish idea. The raindrops simply don’t have a meaningful amount of energy to begin with: https://news.ycombinator.com/item?id=36907674
I would argue that any majoritarian electoral system (winner-takes-all), including ranked choice, incentivizes large parties. There is some nuance between them, but I don’t think that ranked choice can fundamentally solve that issue. Sure, you can enter a protest vote, but will it really change anything? I think that parties need realistic changes at gaining (some) power in order to be viable in the long term.
Would you mind explaining how introducing ranked choice voting would substantially help smaller/additional political parties? I always find it confusing how much Americans focus on the presidency and ranked choice voting when it comes to breaking the party duopoly. At the end of the day, there is only a single president and he/she will probably always come from one of the largest parties. The presidency somewhat inherently limits the influence of smaller parties.
What I would focus on, if I wanted to increase the number of political parties in the US, is the House of Representatives. If proportional representation (e.g. biproportional appointment, party lists, MMP, …) was introduced there, it would allow smaller parties to hold real power. (With biproportional appointment, the seats are distributed according to party voter share while also ensuring regional representation). Do you know why this hardly ever comes up in the context of the US?
What kind of junk energy is there to harvest from a car (in meaningful amounts)? I guess breaking is the obvious answer, but that’s already covered by regenerative breaking. Most car-based energy harvesting systems seem to employ speedbumps that clearly take useful (kinetic) energy away from the car (probably at a very poor efficiency).
