yea, 48kwh to produce 1kg of h2 with electrolysis ?! lol
but also we could rely on saudi arabia’s infinite sunny desert to produce h2 in sustainable quantites.
if solar panels could become more efficient that also would be nice.
also because batteries would require african kids to mine for ur cathode (cobalt) and argentinian kids to mine for the anode (lithium). maybe solar panels are less impactful ?
a tesla model 3 100kwh battery charges from 10% to 80% in 30min with 250kw charger, that means 70kwh for 376km autonomy in 30 min. if u want 1200km range, u need a pack of 223kwh to get that range, and a charging speed of 2390kw to do that in 10min. a pack of 223kw would weigh 1338kg. wouldn’t that affect the car autonomy ? probably. with a hydrogen car, a 5kg of h2 would give u 400km of autonomy, refillable in 10 min, so u would need 3*5kg of h2 tanks to get that charging speed, also 3 ports. are those feasible ? will see.
probably ur battery already formed dendrites, causing it to have micro shorts internally and thus spreading heat in the phone case. a phone with 10w charging causes the battery to heat, let alone ur galaxy s20 charging at 15w. i actively cool my phone battery while charging by putting it in front of a fan so the battery stays cool and doesn’t form dendrites, and thus stays healthy. i also use a silicon case instead of leather else u ll be thermally suffocating ur phone: it uses metal as a case material for a reason. exynos for s20 seem to be made on the 7nm process node which usually should be efficient in term of temps. even when the cpu heats up (even using the 4g antenna, let alone a 5g one when active, the camera flash, all those heats up and causes the phone case to heat up too and then a chain cycle ensues by causing the battery to heat up sponatneously too, then it dries up faster than usual which compels the user to plug the charger and the infinite cycle of heat will never end…i never owned an exynos phone but sometimes a phone need to be underpowered so it could last.samsung phones are really overperforming but unluckely their users aren’t just thermal conscious. no engineering degree is needed to have a grasp over phone thermals but sometimes having some knowledge is needed if u cherich ur phone
