When infant mortality goes down and Children are expensive (need long educational investment) instead of being helping hands in low skilled menial tasks then population growth tends decrease. Modernity reduces the advantages of large families, in fact in some cases modernity causes huge disincentives to large families.
US Census Bureau: annual world population growth slowing, projected to soon slip below 1% for first time since 1950
World population is estimated to reach 7.58 billion this month as World Population Day is celebrated on 11 July, but the US Census Bureau is projecting another milestone: Annual population growth will slip under 1.0% in 2020-2021 for the first time since 1950. The United Nations declared 11 Jul...
I think it's viable but I also think you could either make them one third the weight or three times more HP and torque , also you could use carbon fiber wheels and low weight tires - https://nironmagnetics.com/#technology , http://curtran.com/our-products/magnetic-wire/ , https://insideevs.com/news/318031/breakthrough-insulating-material-lets-electric-motors-perfom-hotter-than-ever-before/
NEVS buys in-wheel motor developer Protean Electric
National Electric Vehicle Sweden (NEVS), a subsidiary of Evergrande Health, has acquired Protean Electric, a leading developer of in-wheel motor technology. The acquisition is part of Evergrande’s strategy to become a major player in the global electric vehicle (EV) industry, and paves the wa...
Give me a car with a 100 miles battery range (around 30kwh) and a 25kws of fuel cells and a tank that lets me have 350 more miles or how about a car that goes around 150 miles on batteries and has a built in hitch and connections that lets you attach a trailer with 35kws of fuel cells and a big enough tank to go an extra 700 miles- you can see the possibilities, you could get away with hydrogen refueling say every 300 miles or so, people would do the majority of their driving on cheap electricity and a couple times a year take long drives powered mostly on hydrogen.
New hydrogen storage material could enable smaller, cheaper, more energy dense systems for vehicles; Kubas binding
An international team of researchers, led by Professor David Antonelli of Lancaster University, has discovered a new material made from manganese hydride that could be used to make molecular sieves within hydrogen fuel tanks. The material—KMH-1 (Kubas Manganese Hydride-1)—demonstrates a rever...
Stronger than pure aluminum but there are stronger aluminum alloys out there, my guess is that the cost must be the breakthrough.
Russian researchers find simple, efficient way to strengthen aluminum-based composite materials
Scientists from the Russian National University of Science and Technology MISIS have doped aluminum melt with nickel and lanthanum to create a material combining benefits of both composite materials and standard alloys: flexibility, strength, lightness. A paper on their research is published in...
A good reminder that while the energy density of the cell is very important, that in the end it's the energy density of the whole energy storage system that truly matters.
SGL Carbon produces prototypes of fully integrated composite battery enclosures for NIO; battery swapping
In collaboration with SGL Carbon, Chinese automotive manufacturer NIO has developed prototypes for battery enclosures made of carbon-fiber reinforced plastic (CFRP) for its NIO high performance electric vehicles. The battery enclosure is extremely lightweight, stable and safe. The entire b...
