Reply to comment by Hot-Praline7204 in NASA invents ‘incredible’ battery for electric planes by HaikuKnives

I've been reading about battery tech breakthroughs since 2008 or so. It's normal that such things take 5 to 10 years to become commercially available and only a fraction manages to get there at all.

Most people aren't aware however how much battery tech developed in a disruptive way. For the past 2 decades, battery prices per kw/h halfed roughly ever 4.5 years. This is due to all these advances that people think never arrive in products because there are so many news on it.

You can see the historic price development graph here: https://ourworldindata.org/battery-price-decline

And btw, for photovoltaic and wind energy, the price development looks fairly similar.

sorry, but price is - at least for me - not THE relevant factor, but energy density is.
Look at this brand new electric vehicle - it only costs 37000€ instead of 38000€ but you still only get 200km range out of it.
yeah.

Daily, few ppl need more than 100km if they can charge at home

This is the one thing keeping me from getting an electric vehicle. There is exactly a 0% chance my apartment will put in a charger so I'm stuck for now

The worst part is they just need a couple dedicated normal outlets in the parking section. Most people would be fine charging their car off a tradional 13A outlet. 1.5-2 kWh would result in 6-8 kWh over night. And at an avr of 0.2kwh per km we get between 6-8km/h so over night that should be 30-50km which is much more than the average city travel.

I know plenty of people who have an electric car in nyc. Apartments don’t have them there. They charge when they go grocery shopping or travel. I do realize that we don’t drive as much as most people though so that might not be realistic for everyone.

yeah, but i don't drive daily, i do most of the stuff in 20km radius with the bike or the cargobike (or with my 50ccm moped)
The distances i use my car for are usually between 400-1100km...

For situations like Urs it would never really be green or economical to go electric. If you can use ur personal transport vehicle or public transport the majority of the time it would be more polluting to get an electric car than it would be to just continue as your were and rent gas when you need distance. Untill we hit some massive breakthrough in battery tek I really see electric as the way to offset our daily travels and then maybe a hybrid solution for long distance
