Cars possible..

But heavy equipment.. impossible yan...

Especially large capacity diesel engine... ex. 1Mw

If ever... Yung battery will be as big as a 14 storey bldg.

Yup,- for all its worth,- battery technology is still way way behind the current technology-requirements.

Matter-AntiMatter powerplant-reactor modulated by dilithium crystals comes to mind...

"Beam me up Scotty"....

There has to be a jump in technology to obsolete fossil fuels...

wait 'til they can replicate dilithium crystals. that way, they won't have to mine it anymore. (sa TNG yata, replicable na.)
bagsak presyo ng dilithium sa galactic market.

btw, what fuel did cochrane use, that first, fateful time...?

as an aside...
"tobacco? nobody cultivates that toxic plant now! but i suppose we can scrounge up a few leaves.. they're weeds now, growing in small patches here and there..."

OT. back to regular programming.

toyota is close to releasing their solid state batteries 😁

hyundai ioniq has the best miles-per-kwh

gotta love tech 😊

the only thing thats keeping people from buying electric cars is price, due to the cost of lithium batteries, that will change soon, the only reason why the americans are in afganisthan, they found a vain of lithium worth more than a trillion dollars there....galing talaga ni bush

"Produce a lot less plastic bags" is oversimplifying it. We still need plastic for almost everything. Products from petroleum are everywhere, used in our daily lives. It's been said that there are over 6,000 items that are, one way or another, came from or was processed using crude oil.

Drilling for oil is not going to stop or slow down for EV. And without internal combustion engines to burn up the petrol, we'd literally have lakes of unused "undesired" gasoline and other fuels. Imagine what that will do to the environment.

oil production depends on demand. we all know what happens when there's oil oversupply. the price crashes and oil production stops being profitable

now take note that solar is right now already cheaper than coal. renewable energy continues getting cheaper while oil keeps getting harder and more expensive to get. see where things are going? at some point in the near future we're definitely going to start dropping oil production for purely economic reasons

take note that we use petro byproducts because they're cheap coz they're byproducts remember LOL. so it's not economically viable to pump oil just to produce these byproducts as "main product". so those lakes of gasoline isn't going to happen LOL

as we taper off oil production the cost of oil byproducts will go up, so the cost of the previously more expensive alternatives start to be become viable. i'm not a chemist but i'm pretty sure we'll find alternatives. it's not like these byproducts contain rare elements or something like that

Good luck replacing petrochem to manufacture the countless raw and finished materials that requires it. There had been alternatives to the use of petrochem. Yes, I did have to research, but the sustainability for it to totally replace crude oil is questionable. It's what's referred to as the Fischer–Tropsch process, where coal, natgas, or biomass are converted to hydrocarbons. But simply put, that will just put us in the same predicament.

Fischer-Tropsch feedstock can essentially consist of any material containing carbon. The most common feedstock materials are coal, natural gas (methane), and more recently biomass. Of these three, coal and natural gas are both geological and will eventually be depleted with varying time tables. Biomass is renewable; however when it becomes the only major available feedstock, synthetic fuel production will be limited by the availability of the biomass material.

dunno why this is even an issue

the global economy runs on carbon (oil, coal, natgas, whatever)

electric cars barely make a dent in lessening global burning of carbon

ocean freight -- those ships that carry container vans from port to port, you gonna put electric motors on them?

airliners -- you gonna power them with solar panels and electric motors?

[uls]

electric cars will be the death of oil?


don't believe the hype

[ice15]

ocean freight -- those ships that carry container vans from port to port, you gonna put electric motors on them?

There are modern ships whose engine is partly electric (like the Prius)
Some has an ICE which generates electricity which powers the electric motor
And there are some who are now running on LNG (still ICE but cleaner)

global economy runs on oil coz it's the cheapest energy. unfortunately this cheapest energy is also harmful

fortunately solar+batteries keep getting cheaper. while oil gets harder and more expensive to get. guess what'll happen when they intersect

the transition isnt' going to happen overnight so don't worry too much LOL

airliners. check out the airbus electric called e-fan i think. simple and reliable electric motor. i guess you already know how complex and super-high-maintenance the jet engines are electric cars and planes operate with the same laws of physics, so why do you think electric planes aren't going to work? soon we'll start seeing cheap short-haul flights because these electric planes are going to be very cheap to operate

ocean freight. did you know that just the few numbers of those large ships account for a very large percentage of the world's pollution? and you wanna continue using them just because they're cheap

If solar is cheaper than coal.... then why is it.. we beat solar phils. In an open bidding for A Power supply agreement.. solar phils. their bid was 9.50 per kw hr.

And by the way, Ours is diesel powered.kung sa Diesek hindi sila nanalo.... sa coal pa...

And AFAIK coal powered power plant cost between Php2-2.50 per kwh...

Alternatives...? I dont think so..... kung magkaron man... can it sustain the worlds demand for oil? But
IF ever they discovered or invented one...

Definitely not in our lifetime...

Maybe the engine won't be replaced but the source of fuel. Heard about those algae that produces fuel in their poop.

but still burning organic matter

corn and sugar cane ethanol and other biomass

cooking oil diesel etc

pero renewables are carbon neutral. it does not add more carbon to the atmosphere as what the plants it came from absorbed from the air.


ships? yeah no way. mas malaki/mabigat pa battery kesa sa cargo.

planes? again, the weight of batteries and motors. also those turbines are very reliable. have not heard of any turbine engines on planes giving up in mid flight for the longest time. and you want to replace them with electric? how many kw is one 777 engine? na google ko na, 110,000 hp. HOW BIG AND HOW HEAVY DO YOU THINK A 110,000 HP ELECTRIC MOTOR IS? naaaaaah, it won't fly. baka ni hindi gumalaw yan ng walang humihila hahaha!

[yebo]

yung submarine oo pwede. pero naman, good for 2-3 days lang and only at speeds a fraction of what it can do when running on diesels. saka ano ang cargo ng diesel-electric submarine? 40-50 guys and maybe 18-24 torpedoes. sabi nga ng mga ss guys na nakasama ko (they work mostly as electronic tech on the rig) natutulog sila sa ibabaw ng torpedo kasi wala silang quarters. sabit lang ng hammock o latag ng mattress. nuclear subs pa yun e di lalo na pag diesel-electric sub mas tipid sa weight.

Hehe.

I've seen some demo flights of electric planes.

A passenger carrying electric is possible... but size, range and speed will be much lower than we're used to... and the battery packs will be horrendously heavy barring some major breakthrough in battery tech.

EVs are a possibility, but I think we will need a paradigm shift to occur for the EV ecosystem to work. We're just too spoiled by what we get with gasoline that it raises the bar too high for the current EV state of the art. Not that EVs cannot perform as well as gas cars. It's just that they cost a hell of a lot more for the same "performance".

And no, don't cite Tesla. When you're talking luxury sports cars, a lot of what's in the price is not down to the actual cost of the vehicle. Bring it down to the mass market level, and an EV is still around twice the price of a comparable "family" car (Nissan Leaf).

[Vodka]

yep airbus' e-fan is already flying and they're already building the e-fan X which has like 10x the power. but of course battery tech has to improve in order to get to A380 capacities but as i said short-haul is already on the horizon. imagine not having to do the usual servicing that you have to do so often on conventional aircraft engines

as for electric car costs, they just keep going down. the physics certainly allows them to get cheap so there's no "brick wall" here. it's just a matter of developing the tech and leveraging economies of scale. in fact the car i'll pick up tomorrow would probably be my last combustion engine car

How many poop do u think will power a 1Mw engine.. for a day? Maybe as big as Q.c. hall.. he he..
