Another source for hydrogen is natural gas. From wikipedia, "Hydrogen can be generated from natural gas with approximately 80% efficiency". Where are you going to get your renewable power? It's a lot like running your car on recycled french fry oil from restaurants. One or two guys do it, and they're visionaries out to save the planet. (And everyone in the neighborhood starts craving some McD's fries) The whole town does it, there isn't enough (free) recycled cooking oil to go around, we have to divert corn production from feeding the masses to making fuel, the masses can't afford corn any more and the visionaries can no longer find recycled cooking oil. If you're going to get your hydrogen from natural gas, why not just run them on natural gas? The technology exists, the infrastructure to refill is already in place in many locations. I'm all for electric cars for the vast majority of commuting. (Not hydrogen until they get the cost/HP for fuel cells down and prove we can haul high pressure hydrogen in millions of autos without burning up a bunch of people). But the electrical grid is already heavily loaded in lots of places, lots of us live in high rise apartments with no charging facilities, and I don't want to be locked into 1 car for commuting and a second car for long road trips, even though I could afford it. Edit: Still, my next car will probably be an electric. Even though I make my living in the oil business. I'm an engineer, and I'm hoping to build my own solar charging facility since solar panel prices are dropping so fast. But I'm willing to concede compromises that the majority of the motoring public can't or won't (I'll be retired). And I can afford some experimentation as a hobby.

It also might lead to certain businesses having plug-in parking spaces dedicated to such vehicles. Central Chitlom already have a charging station at the 2nd floor parking area. In time all shopping centers, condos and office buildings will have charging areas. Since everybody reverse park, they might even automatically plug when you park and disengage when you drive out. The car could have a top-up credit card system, that is automatically deducted when charging. Easy and simply. Link to comment Share on other sites More sharing options...

I wasn't advocating the use of hydrogen, just explaining on how and where to get it. Regarding your last comment of 2 cars, that is where a plug-in hybrid slots. You use the electric motor for driving around town (about 40km range currently) and the petrol motor for longer trips. I understand the current electrical grid might not be up to the challenge but that could change. Link to comment Share on other sites More sharing options...

These plug in cars can't be charged by their own combustion engine so you need access to a electricity source. Where will we find this in Bangkok? Sent from my iPhone using Thaivisa Connect For now plug-in hybrids get a tax break, that is the reason for BMW and Mercedes to introduce the 7 and S-series as plug-in hybrids in Thailand.

All these guys love to say 60 miles per gallon , but do not factor in th cost of the electric , batteries have only so many charge cycles before they need to be replaced at huge cost , What happens when 20 electric cars need to recharge for 1-2-hours and there are 5 plugs ? ( sometimes 4-8 hours) right now the answer is Hybrid electric , and maybe make the electric a larger part of the "hybrid" mix , But consider using a Hybrid in Thailand , limited battery power and high temps so you need AirCo , do you use up you battery power to keep cool in traffic , or your Petrol ? As is said , not ready for prime time yet , but it is getting better and a better battery power to weigh ratio plus quicker recharging is the key..... Electric vehicles will probably go through a product cycle similar to that of flat screen TVs. Do you remember back when a 42" plasma TV with a resolution of 480p was 300,000+ baht? Now they throw a 50" LED with a gazillion pixels at you for less than 20,000 baht. I thing we will see a huge battery recycle or refurbish industry coming along, bringing down the price of replacing the batteries. Link to comment Share on other sites More sharing options...

Had to chuckle at that one when I see that a lot of people can't even keep it between the 2 lines when they park, especially back-in. Don't get me wrong, it's a great concept. And that brings up the question of compatibility. If you're using standard extension cords, no problem. But any kind of rapid charge system is probably going to need something specialized, heavier and more expensive. And I can't even charge my Samsung phone on an IPhone charger. And now they're going to USB C. Imagine the $$ billions to spend keeping up with the standards as e-vehicles evolve.

impulse Posted December 5, 2016 Share Posted December 5, 2016 BTW Great Youtube called "The revenge of the electric car". Pretty inspiring for anyone who remembers "Who killed the electric car", which can be found all over, but I'm not sure if it's legal, so ya gotta find it yourself.

Cars may be parked for 95% of the time, but most people drive in spurts at least occasionally. Just the thought of having to plan a weekend days' outing to accommodate a 4-8 hour break for charging up the car would reduce the potential customer base. These are the same people who pay big $$$ for AWD for the 0.5% of the time they may need it. We're spoiled. Link to comment Share on other sites More sharing options...

Grouse Posted December 5, 2016 Share Posted December 5, 2016 All great ideas but you need to do the maths. Let's say we assume 100kW required for say 4 hours driving. How many batteries for 400kWh? Let's assume a lead acid battery rated at 100Ah. About 1.3kWh. So that's about 300 batteries. Weight? 5kg? So that's 1.5 tonnes in batteries! Now, what about charging? Maximum 2 hours? How many amps? Volts? 230V ac is 400V peak so 4 banks of 75 batteries at 400V DC. Maybe 40kW charging requirement? The above is a very rough indication.... In short this all requires big infrastructure and power generation. Nuclear is the only way. Link to comment Share on other sites More sharing options...

Take away all those freebies, Tesla recently removed the free charging already, and look how the popularity declines. Solar energy was also very popular, until they removed the tax breaks. Oil powered vehicles have been getting tax subsidies forever as we spend $$ trillions on defending corrupt governments in the Middle East (Edit: then spend $$ billions fighting the terrorists and supporting the refugees that spawns) $$ billions to keep the sea lanes open for tankers, and $$ trillions to treat diseases brought on by pollution. Not to mention the millions of years of life cut short every year, including our kids' blood spilled defending the world's oil. Seems a reasonable investment to subsidize alternatives to help them get caught up to oil's head start. Edited December 5, 2016 by impulse Link to comment Share on other sites More sharing options...

oldcarguy Posted December 5, 2016 Share Posted December 5, 2016 I could use a EV as a 2nd car .......if....... it was a real size car , not a SMART car minicar it had 75-100 miles real range , up and down hills , highway speed with either the AC or Heater on plus Headlights , That when you came home you could park it on its charging center, not have to plug it in , just park it , full recharge can be overnight , but you could FAST charge in 2 hours or so.... Batteries were 5-7 years and if they did not do 70% charge at that time the replaced them for free , That would do 80% of my driving needs , but I would still have a 2nd "regular" car for days like today where I needed my Truck Link to comment Share on other sites More sharing options...

mania Posted December 5, 2016 Share Posted December 5, 2016 (edited) Prediction from the cheap seats...... All this electric vehicle stuff is making the mistake of trying to move via brute force much like our space programs mistake to break thru gravity with brute thrust Someday someone will look for energy from a clean slate ignoring old tech They will use something that exists all around us freely like the geomagnetic field They will surf over & with waves rather than try to swim thru them as they now do Edited December 5, 2016 by mania Link to comment Share on other sites More sharing options...

I am not arguing with you and I am pro electric cars! My point is that whereas using electrical energy directly or using fuel cells will require a huge increase in generating capacity! BTW 100kW is 134bhp, 25kW is 33.5bhp. In addition to power to achieve a constant speed we need sufficient power to accelerate up hill with full load including a "ton" of batteries. My calculation was wrong again - that's what you get for going on TV in the middles of the night! 230V ac is 325V peak So, probably 12 banks of 25 batteries. The mass and volume is a serious issue. Lithium Ion is much more efficient but still not good enough. We need a breakthrough here! So, in conclusion, electric cars are indeed the future. Generating capacity and battery technology are the issues. Charging infrastructure is no problem. BUT many homes will not have the electrical capacity to install fast charging gear in the garage !
