Mercedes to be petrol free in 7 years?

this article on TheSun.co.uk indicating Mercedes are looking to make petrol-free cars sooner rather than later:
Mercedes are convinced that these two crucial areas of industry can be saved by making vehicles independent of crude oil - to improve costs, become more eco-friendly and because the oil supply will eventually run out.

The company have already spent �2million on their new long-term Sustainable Mobility plan and are set to invest a further �7billion before 2014.
Of course, the sensationalist headline which I have shamelessly ripped as the subject and is being spouted all over the internet stems from a less-than-concrete comment:
Professor Dr Herbert Kohler, responsible for Mercedes� advanced engineering, told me he believes that by 2015 motorists will have switched almost completely to alternative fuel cars, certainly in cities, to eliminate the need for petrol and diesel in urban areas.
So it's not official Mercedes policy yet, but hopefully will kick off more changes.

Totally agree Insom.

Until a 'Major' Car Maker starts mass producing a Fully Electric Vehicle, they will always be too expensive.

However, as mentioned previously, Toyota and GM do have their 'Plug-In' Serial Hybrids due for release in the next few yrs.

These 'Range Extended' Electric Cars are basically an Electric Car with a petrol engine as a generator only. Unlike a standard Parallel Hybrid (Prius/Civic) the drivetrain of a Serial Hybrid is powered exclusively by the Electric Motor/s.

Plug-In Hybrids really are the best of worlds. Charge up at night for your daily 40mile commute to work and on the weekends when you want to drive up/down the coast the petrol engine kicks in for the typical range of a petrol car 300+miles.

theres almost 14million cars on the road in australia, australians buy 1 million new cars a year.

10,000 cars a year is a piss in the ocean to the 1 million cars sold. and its completely blown out of the water by the 14million cars still on the road.

plus, even with petrol at $1.60 its still cheaper for me to drive a 2.5tonne 4wd to work everyday than it is catch a bus or train.

It wont. The pending 10,000 Aussie Camry Hybrids are powered solely by Petrol. Standard Hybrids and Diesels are simply 'rearranging the deckchairs on the Titanic'.

The Australian Car Industry is finished. 'Hairdresser Hybrids' will only keep the Altona Plant open a few more yrs. Reason being that Major Carmakers are already setting up plants in China where they could probably make a fully Electric Car (or any car) for a pittance compared to what it would cost to build the Car and Batteries here in Australia.

Totally agree. However not all cars can be converted to Electricity. Its simply not practical. Electric Drive works best in residential commuting. Using ED for Heavy Commerical Vehicles, Aviation and Marine, just doesnt work. Maybe Hydrogen will be better suited to those applications.

Either way we will need a s*** load more power generation to create electricity for transport and to make Hydrogen via large scale electrolysis.

My guess is that they will use the lot: Nukes, Coal, Wind, Solar, Tidal, Hydro and Geothermal over the next few decades.

Interesting times ahead.

hydrogen isn't really a great option. its got a pretty horrible energy content, and fuel cells (atleast currently) require loads of expensive metals. quick google says fuel cells are about $4000 per kw. even for a small vehicle you'd be wanting something like 25kw as a minimum to satisfy peak demand. thats a lot of cash. the metals are also quite rare, so mass producing would actually increase the cost of a fuel cell because of good old supply versus demand.

if you burn the hydrogen you end up pumping out nitrous oxides which negates the whole zero pollution thing in the first place. they are also less efficient because hydrogen is a horrible fuel in a ICE.

Plug in electrics aren't really the answer... Most people will be plugging their car in to get it charged by a coal power plant that burns coal that relies on oil to be mined.

Hydrogen fuel cells are also a joke. There's the problems nF mentioned, and there's also the difficulty in harnessing hydrogen. Where do people propose we get it from? Water? OK, then you just need a s*** load of energy to separate the water molecules. Where's the energy going to come from? A coal power point most likely.

Biofuels are also a joke. Even if we started growing hemp for biomass to create fuel (hemp is one of, if not the best biofuel crop AFAIK), we'd need to plant so much of it to replace the excessive amounts of petrolium we use that we'd run out of space to grow food.

The manufacturing of a 'oil free car' is also an issue. To manufacture a car it takes about as much oil as it will use in its first year of running (this is a very broad average). Even if a plug in car uses no oil once it's made, it will use a year's worth of oil used by an average car just to be manufactured. Everything in our society is touched by oil in some way, and the vast majority of people fail to comprehend just how much our lives will have to change as oil gets more expensive. It won't just be hard to get around.

Don't get me wrong mate - mining does use a bit of diesel, but all the massive mobile machines you see (dragchains, draglines, stacker-reclaimers etc) + the conveyoring systems use HV electricity (usually 3.3 or 11 kV).

I'd wager that you'd see a massive reduction in oil. The CO2 emissions from new coal-fired stations would be the next thing to look into. The bag-filters & electro precips on a modern station get pretty much all the particles.

There are coal deposits out West in Queensland that make the Bowen Basin reserve look tiny. There's no way we'll be changing over from coal as our base-generation fuel of choice in the next couple-of-hundred years.

orbs might have some idea, but i wouldn't be surprised if electricity prices double or triple in 5 years. and thats without people plugging in cars.

you'd be better off getting a hundred amp hours worth of batteries an inverter and rewiring your household lights to run off it. cause thats about all it'd be worthwhile for. atleast you'll have a light to turn on then when the noise of the wind turbine stops you from sleeping.

Yeh wind turbines in urban area's would suck. The noise problem would pretty much get them banned.

Solar panels ftw, especially here in sunbaked oz. Before someone says 'Solar Panels cost to much' (which is currently true) the fact is that Solar Panels and NanoTech is improving at a steady rate. Once the chinese start pumping out these cheaper next gen panels it will be more feasible to cover your roof with panels. Although even the most well intented and efficient use of resisdential Solar Panels will only offset a portion of an average household's power needs during daylight hours. It will never provide base load power!
But with the pending increases in electricty costs, Solar is looking better all the time.

there is already a guy who has invented "solar paint", so you just run the pickup wires across a surface and then paint it with the "solar paint" instead of using panels.

are you sure about that? i always thought burning hydrogen with oxygen at an optimal mix of 2 to 1 results in H^2O, i.e. water.

last i heard tapping into the power grid earnt you something like 10c a kw/h


if you have solar panels and are doing grid feed (hooked into the grid as well) when you are using less power then you are producing your meter runs backwards. therefore it stands to reason that you are getting paid the same amount as you pay for Kilowatts from the electricity company.

at present that might be ~12c/KW but it is only going to get more expensive where as with the continual focus on energy efficiency household power use is hopefully going to stay the same or decrease.

nitrous oxides are produced by a hydrogen ice in exactly the same way that they are produced in a petrol or diesel ice. its due to the temperatures of the gases causing the atmospheric nitrogen to form oxides. its not a direct by product of the burning of hydrogen.

ok its about 3.5c per kwh for grid connected solar which in brisbane would make about 10-14c a day with a 1kw solar array.

so within about 80 years a $4000 or so grid connected solar install (after rebates) would be earning money.

basically, solar sucks balls. and its being propped up by government rebates when the dollars would be better spent elsewhere.

The big cost in solar though is still the panels, right? As soon as demand gets high enough won't we see a decrease in the panel cost?

just for arguement sake, i called AGL to ask them. They gave me the following figures (it appears it does vary based on the distributer for your particular area).

Victoria
Origin
15.61c/KW
AGL
15.42c/KW

Queensland
Origin via Powercor
15.77c/KW

Origin via Citypower
14.17c/KW

All these seem pretty good considering that the current tarrif i pay is ~11c/KW.

I realise this is a bit vague, but about 6 years ago when we built the house we're living in now, we worked out it was going to cost us about 17k in equipment and labour to get ourselves completely powered off solar - and based on the calcs energex did with us after we provided all our appliances and looking at our previous usage it was going to take about 25 years to break even using moderate to worst case figures.

A grid feed system uses electricity produced by your solar panels to off-set or negate the amount of electricity purchased from your energy retailer. It does this without the need of batteries using a sophisticated grid interactive inverter to produce mains voltage electricity. A special meter provided by your local energy authority meters both import and export of electricity.

Currently the solar energy that is produced off-sets the amount you buy at 1:1, however, with feed in tariffs already operating in other countries and soon in Australia, a premium price for your electricity would be your reward for producing clean, green energy

Oh sorry, my mistake. I was reading the REC value as the tariff (which is 3.5c/kwh). That goes to the electricity company which probably explains where i got the initial ~10c/kwh from.

I'll try again.

4000/0.65c a day ~= 17 years to pay it off if you're doing nothing but pump out solar. if you are using electricity it'll be more than that as it'd be reaped as savings at the 11c tariff.

By saying make energy cost more, I mean tax the f*** out of it. Use that revenue to fund R&D tax rebates on currently marginal technologies to accelerate their viability.

While present polluting technologies remain cheaper people will delay jumping on the next wave of technologies.

It astounds me that no government has started factoring the environmental costs of polluting energy into its economics.

by marginal you mean uneconomical.

aka, solar. niche solutions that don't work on a larger scale.

also, jacking up local energy costs (especially for polluting ones) pushes energy intensive processes off shore into countries who don't give a f*** about dirty energy. nothing is solved there, atleast globally. its probably a big step backwards. there needs to be a global system in place and it has to be market driven, if it isn't then its not a real solution.

s*** like solar just can't work mainstream, if it was mandated that every new house had 2kw of solar on the roof the only thing that'd change would be that raw material prices would go through the roof (selenium has increased in price by a factor of 5 in as many years as it is). the economies of scale would vanish under the increased cost of materials and to be honest i doubt there'd be anymore benefits to scale than have already been seen. certainly not enough for solar to stand on its own two feet without subsidies even without the increase in raw material costs.

no, marginal means due to the current lack of popular use the minimal number of units are too expensive.

all technologies have high startup costs when they are in their early development (think BluRay players, Plasma TVs and DVD recorders etc).

if government acknowledges the economic benefits of non-polluting energies with financial incentives/disincentives, then this curve can be accelerated and allow popular take-up prior to the breaching of the necessary pricing points in the market.

see for example the speed with which the water tank rebate program flew off at with government and council rebates, and they were very small amounts of money which changed consumers minds and acceptance levels.

re jacking up energy costs, they are already spiraling out of control (petrol duh). aussie exporters are well-versed in keeping costs low as we battle a strengthening aussie vs us dollar.

I used to think that we need to wait until a scheme exists which includes China, India and Africa etc but to be honest that may never happen. Someone has to take the leap, I want to start moving in the right direction, the benefit to Australia in the long run may be that technologies are developed which are even cheaper than fossil fuels.

Aside from Head and Shoulders, what else is selenium used in that I would care about?! (thank you David Duchovny and Evolution)

Surely some other raw material prices would come down. If everyone had 2kw of solar (even 1kw) then during the day we'd need (x) amount less of coal burned, meaning demand for coal would go down, right? At least in .au industries. Then there's the other benefits such as massively reduced CO2 emissions.

As has been pointed out we don't NEED it in Australia cuz we have awesome coal (not to mention uranium), but I'd still like to see it. It annoys me to see our stupid sun wasting all its stupid photons on things like roads and tin roofs.

the calcutions dont take in inflation. its like people doing the maths on LPG v Petrol. When i got my car done (7years ago) petrol was $.60 a ltr

Man I love that Tom Hanks is pushing electric cars



I don't want a roof full of solar panels or wind gens to stop me having to pay for electricy ever again... I just don't want to buy petrol ever again.

ever.

ever.

again.

of course if it goes like this baby that'll kinda be a bonus. not a bad car considering it runs on modded electric forklift motors

hi all
i'm back


also

There have been cars around for years that don't use any petrol. They're called LPG cars!

I don't know why people overlook LPG so much, when they are happy to put up with the exceptionally slow/small hybrids.

welcome back!

re lpg:

...

it comes from crude oil and/or naturally occuring LIMITED sources from under the ground - and it's btu sucks

which means it's just like using petrol, but you churn through your limited supply much much faster. haven't we been through this before?

I was chatitng to a guy who is heavily involved in the solar hot water heating industry, and he was telling me that when you consider the outlay for the product, the savings over the years and the current life cycle of the product, you should just cross the line over breaking even financially. So I guess it's just one of those things you do for the sake of doing a good thing.

there is already a guy who has invented "solar paint", so you just run the pickup wires across a surface and then paint it with the "solar paint" instead of using panels.

I remember reading something a few years back about a solar cell that could be literally 'printed' onto a material as thin as paper. So essentially you could coat roof tiles in a sheet of this material and rig the tiles up to feed power into the house/grid. As with all things solar, the extreme cost to power output ratio was the killer. There's also the factor of being a new technology, so it's not entirely dependable etc.

all technologies have high startup costs when they are in their early development (think BluRay players, Plasma TVs and DVD recorders etc).


big difference is that chips get cheaper over time because they get smaller. smaller chips meaning you get more chips on a given area of silicon. early adopters also pay the majority of the r&d costs. bluray players aren't getting too much cheaper anytime soon because of the rarity of the s*** in the lasers.

if government acknowledges the economic benefits of non-polluting energies with financial incentives/disincentives, then this curve can be accelerated and allow popular take-up prior to the breaching of the necessary pricing points in the market.

see for example the speed with which the water tank rebate program flew off at with government and council rebates, and they were very small amounts of money which changed consumers minds and acceptance levels.


water tank example is a good one, what happened to the price of water tanks. they doubled. and what difference did it make in the end? how many people with the water tanks have actually tapped them into their toilet, washing machines, etc?

I think the vast majority of people need to wake up to the fact that we really don't have some sort of viable 'genie in a bottle' to save us from the demise of oil. There simply may not be such a high energy yielding substance/process as fossil fuels/nuclear materials. We may have to entirely rethink and change the way we live. Name ONE alternative energy option that isn't a joke or propaganda.

Biodiesel? Unfeasible on a large scale.
Solar? Stuck in its infancy.
Wind? As mentioned, the problems with sound and efficiency.
Fuel cells? The materials used are largely reliant on fossil fuels.
Tidal? This has potential, but it would be a tremendous undertaking to use this on a large scale using current tech.
Hydroelectric? Good luck getting hippies to let you build dams.
Geothermal? Unless you're piping water down there yourself, it will eventually run out (see what happened in California in the 70's). Plus only 10-15% of the world's population live in places where geothermal energy can be utilised.

Every step companies like Mercedes take is a help, every little bit counts. Don't go thinking that plug in cars will save the world and keep your life the way it is now. Most 'oil alternatives' just result in a longer tail pipe.

Cizane Tribal I posted 2 utube vids showing a solar printing machine on the previous page.

Also there is a Solar Thermal plant operating in Spain.



Basically its a field of mirrors reflecting the sun's energy towards a solar tower that heats water, turns a turbine.

Just seems crazy that here in Australia we have insane amounts of useless desert wasteland that's baked s***hot everyday and we do f*** all with it.

Thers is no silver bullet technology. Power generation has and always will be best served by a variety of technologies used where appropriate and supporting each other to overcome their individual deficiencies.

Biodiesel: agree, currently. Better to use biomass to feed high efficiency power stations anyway and run electric cars from them.

Solar: solar PV is a well-developed technology, but it's too expensive except for remote communities. Nanosolar-type tech might give a technological breakthrough that is needed to make it feasible. Solar thermal is an emergying tech with good potential. Distributed solar may get an economic boost if you take into account the cost in new powerlines etc. that would otherwise need to be built. If the price comes down significantly in the next 10 yrs, we'll probably see legislation that forces all new buildings to incorporate solar (or other).

Wind: there is no problem with efficiency. This is the best and cheapest form of renewable energy for us to tap. Not particularly viable in QLD but in VIC, SA and TAS there are potentially thousands of megawatts possible. Sound isn't a problem if you put them somewhere really windy as you can't really hear them over the wind!

Fuel cells: long, long way to go before they're remotely affordable.

Tidal: potentially massive resource, current tech is expensive and unreliable but emerging techs (buoy surface type) are making this look promising.

Hydro: ain't gonna happen in Aus. Our big hydro resources are declining. Snowy's Eucumbene is at record lows and would need years of biblical floods to restore it. Tassie is struggling big-time too. New hydros are infeasible if your storage isn't reliable.

Geothermal: Another tech with massive potential but large scale plant is a long way off yet. It's also located nowhere near the load centres which means massive, very expensive transmission is needed. Your comments about water use are only relevant to steam-type geothermal which is different to the new closed loop hot-rocks technology proposed for australia's geothermal resources.

Then there's the BIG one you haven't mentioned, which is Energy Efficiency. At the moment we waste amazing amounts of energy as our houses, apartment & office buildings, shopping centres, warehouses, etc. are designed with very little consideration of minimising energy needs. Then there's the energy waste in inefficient lighting, air conditioners, heating and refridgeration. Then there's every appliance you can buy - they're all currently designed to the lowest purchase price rather than minimising energy use.

Energy efficient design will definitely be legislated and new buildings will all have to meet stringent designs so that they minimise the need for lighting, heating and cooling. This is a good thing as it will in fact save money in energy bills while only increasing build cost by a small amount.

Check this crazy s*** out:



200MW Solar Tower concept to be built in the Outback. Best thing about it is that it uses no water. The Solar Tower uses turbines that utilise the air rushing into the base of the tower.

Arizona has lots of it too.. I never thought I'd see a US govt dept push the 'green' card for this, but given the new solar gold-rush that was on it had to happen.

the same thing has already happened with wind power here in Aus already if you google it

"it's all going diesel" is actually a bit out of date now - they already went diesel bigtime in EU several years ago - it's just that australia is behind in that regard, to some extent anyway (and the US even moreso due to emissions laws). merc bmw and audi have all had diesel models in aus for a few years but the newer technology is only just arriving here and even it isn't the latest. for example in aus you can only get the 280/320 in merc while europe enjoy the juicy 420 diesel as well. and australia only just got the twin turbo 3.0sd X5 from bmw at xmas (previously only had the 3.0d), and in the audi department I think we might've only just gotten or are about to get their new 4.2 diesel (previously just the 3.0)

and even now, we still don't get the urea injected versions which eliminate (claimed) 99% of nox, although we do get selective catalyst reduction in the form of additional particulate filters which is still good. the bmw x5 with the new twin turbo 3.0 diesel has absolutely no visible smoke or soot or diesel smell at all, so apart from the noisy idle you can't even tell it's diesel until you put your foot down and feel the extra torque at low rpm

bmw are pretty heavily into hydrogen, they've been parading a 7 series around the place even in australia for the past 6 months or so. conveniently, it has it's own hydrogen refuelling station that gets trucked around with it - if only it were that simple for everyone who has a car ;)

and several of the euro manufacturers are bringing out diesel hybrids (which makes a lot more sense than petrol hybrids) audi bmw and merc included. bmw even have an X5 diesel hybrid which is basically production ready

the performance figures of that hydro 7 are undrastandably since its in its infancy are so crap though :(

Regarding the engines though they have some very nice stuff, I went to the BMW welt last month and they had the X6 with that twin turbo diesel. A mate bought a 330xd and that thing hauls on the autobahn as well, was so suprised at how much torque it had compared to my old bimmer and couldnt get used to the fact that I didnt have to rev the s*** out of it to enjoy the driving.

I have no idea what you're referring to here koopz ^^ besides, while the 280 obviously had better fuel economy than the 3.5 litre petrol variant, it did not 'flog the s*** out of it' - the 350 was 8.4 seconds 0-100 and the 280 was 9.8 seconds. I've still got the brochures right here.


anyway I checked the merc site and now there's even fewer options available. when I was shopping a few months ago they had a 280 and 320 diesel, a 3.5 litre petrol as well as the 500 which is a 5.4 petrol. not to mention the 63 in the M class.

now they only have a 320 diesel which is a 3.0, and the 500 petrol which is 5.4
so we're still missing out on the 4.2 diesel here :( this is across both the M and GL classes

nF, find a way to complain about the awesome of THIS!
The tower project is called �PS10″ and it uses 624 large movable mirrors called heliostats. Each of the mirrors has a surface measuring 1,290 square feet that concentrates the Sun�s rays to the top of a 377 foot high tower where a solar receiver and a steam turbine are located. The turbine drives a generator, producing electricity.
