BMW Hydrogen 7

[starnberg2413]

...das mag am 12.09.2006, also vor fuenf Jahren, gestimmt habe, als diese Video gepostet wurde....

Mittlerweile hat MBW, wenigstens offiziell, ALLE Waserstoff-Fahrzeug-Aktivitaet­en eingestellt. Es lauft lediglich ein (1) letztes Fahrzeug vom Typ BME Hydrogen 7 (alle anderen sind entweder verschrottet oder stehen in Museen) in Berlin, wo es noch ein kleines Foerderprogramm gab/gibt. Also bitte bei der Warheit bleiben..bzw. abund an mal updaten...

[EsterinMovement]

super schlecht das video

[ukuleleles]

@RCPhilN also, i forgot to mention, you would need a huge amount of solar panels to power these cars because is not only one or two, there is millions of cars, once again we need an efficient energy source. also if you are powering these cars with electricity  (as a source) let me say that the bmw h7 takes 254 kWh per 100km. other cars like the tesla roadster or the aptera, take 15 and 6 kWh per 100 km. once again electrolisis is a waste of money, time and low entropy energy.

[ukuleleles]

@RCPhilN solar photovoltaic is so expensive you wouldnt even dream about it, also their lifetime is around 30 years and they give you benefits after the 31st. they need subsidies, also solar panels are around 30% efficient, 40% the expensive ones (with mirrors and good quality of silicon) what it means that the other 70% left is converted to heat. this heat produces changes in the environment like changing the levels of humidity in air and evaporating any water around. do you really want that??

[ukuleleles]

how do we get hydrogen?. from electrolisis. How does electrolisis work?? passing a current through water. how do we get the electricity?? burning fossil fuels. if anything, this car is wasting the energy waste in all those nonefficient ways of transforming energy. making these cars is easy, what is difficult to get is a sustainable energy source! for example nuclear fussion.

[RCPhilN]

@ukuleleles Solarbatteries give enough Hydrogen power for a small city car.

[xparade0de]

Beste Technologie ! - kein E10 das weltweit zu Hunger und Regenwaldvernichtung führt und keine Batterien die Sondermüll sind und nur wenige Jahre halten - sondern einfach nur umweltfreundlichen Wasserstoff den man auch wunderbar mit Solarenergie oder Windkraft herstellen kann - es gibt noch hundertausende von Dächern in Deutschland auf die man Solarmodule bauen kann

[barrettski189]

Ich will garnicht wissen was der kosten soll....

[and87gamer]

@barrettski189 ~8€/KG das wären beim 7er 16-20€ Verbrauch, da er 2-2,5KG verbraucht auf 100km.

[UglyButPsycho]

@and87gamer Ich denke, er meinte in der Anschaffung, nicht im Verbrauch... Außerdem, wieso denn 8 € pro Kilogramm Verbrauch auf 100 Kilometer? Man tankt da doch simples Wasser, Literpreis etwa 1ct oder hab ich irgendwo was nicht mitbekommen?

[and87gamer]

@UglyButPsycho ne du simples Wasser wird da nicht getankt... somit isses Teuer!

[UglyButPsycho]

@and87gamer Jop, warn Denkfehler!

[xparade0de]

@and87gamer teuer ? Strom in Akkus zu speichern ist teuer ! Normalerweise bezahlt man für den Strom und den gleichen Preis noch mal für den Akku denn der hält nur ca. 5 Jahre und dann ist der Sondermüll. Wasserstoff hingengen kann man auch günstig mit Windenergie und Solarstrom herstellen. Wenn man Ihn aus Windenergie herstellt ist auch das Problem mit den Stromspitzen der Windräder weg. Da überschüßige Energie dann einfach umgewandelt werden kann.

[dzanicjasmin]

THis is the future. But the problem is the engines and fueltanks size and the performace and range.

But fueling destilled water wich is turned into H2 is awesome and water is nearly free. Wonder what the big oilcompanies thing og this.

[Errorbgkn1]

@dzanicjasmin preformance should be no real problem because hydrogen is much much more explosive than petrol but your right the question of range still remains

[DiggaBua]

@dzanicjasmin But compare the Range of a BMW Hydrogen with a Electic Car... Hydrogen 500Miles, Electric car: Not even 200 Miles..... And the Hydrogen is faster than 120MPH !

[xparade0de]

@DiggaBua - Yes and Hydrogen Cars are working without toxic batteries and do not cause a giant amount of hazardous waste

[xparade0de]

@DiggaBua Yes and it does not need toxic batterys and produces water instead of toxic waste (accumulators do only work for 5 years) and It is refueled in a few Minutes and not hours.

[nformby]

This is a much better way of powering a car using hydrogen than the way the Honda uses to power it's FCX Clarity. I never thought that you could use hydrogen like petrol because I thought that Honda used it to generate electricity to power electrical motors because there wasn't another way. This video just makes that way look stupid to me, and much less efficient. Well done BMW! Hydrogen, Petrol V12 hybrids all the way!

[MadsWest]

The thing is that this way is VERY insufficient compared to Honda's hydrogen cars. This way is actually quite stupid as you still have the biggest bottleneck as in a normal petrol-driven car: the insufficient, internal combustion engine. This is a very unambitious sullotion compared to the traditional hybrid car, because of the big losses of kinetic enegy in the engine.

[glennimmortal]

Youre an idiot, Hybrid cars are marketed to well to do middle classes so they feel good about the money they spent and they are a step backward in replacing the fossil fuels. Feel bad buy a motor cycle and save way more then any other solution get rid of cars, step back and look at it globally there is a hard place in front of us and behind is a big rock. Even if GM announced tomorrow that they had a car that run on nothing replacing the worlds current fleet would be a massive world eco drain.

[glennimmortal]

Hydrogen allows us to upgrade our existing fleet any combustion engine can run Hydrogen, plus hydrogen can greatly increase the inefficiencies of the old combustion engine by increase the flam or burn speeds of gasoline or diesel which is way to slow. Hybrid cars have some cool stuff in them but as Proven any many economy races it loses the battle lugging around all the junk, where as the super efficient modern common rails diesels are winning. Cars are to big and heavy as a rule!!

[MadsWest]

Well.. thank you for the kind words..

And NO a motor cycle is NOT more sufficient than an electric driven car and does not eliminate the emission of carbondioxide, NOX and sulphur particles.

As you seem to know nothing about the subject I want waste more of my time on you.

[sailboot]

@madswest

its not wrong what u say that hydrogen cars are not more efficient than electro cars, but there is actually zhe fuel cell wich conjunct electro engine with hydrogen.

p.s:sry for my english i know its not really well

[donaldaholmes]

In physics there is a law called the Carnot's Law (Efficiency): in brief it states the maximum amount of heat energy that can be harnessed and turned into movement is around a third. That is why coal fueled power stations only convert about a third of the chemical energy stored in the coal into electricity (the rest is heat). Since the Honda uses a fuel cell and converts much closer to 100% chemical to electrical to movement energy, the Honda therefore must be greatly more efficient.

[apeson89]

Believe in Hydrogen! There's no better alternative!

[240SSONLY]

@apeson89 wise words... 130 octane i agree...

[DiggaBua]

@apeson89 Produced by Nuclear Power! Nuclear = Future!

[apeson89]

@DiggaBua Ja, aber das Problem mit der Lagerung vom Atommüll ist etwas, das unlösbar ist ^^

[DiggaBua]

@apeson89 Ein Atomkraftwerk Produziert jährlich ca. 30t Abfall.... davon werden ca. 2/3 wiederaufbereitet = 10t Abfall der nicht aufbereitet wird. das ist nicht mal ein 2x2x2m großer Würfel. Und wer sagt denn dass nicht in 20 Jahren diese Würfel aufbereitet werden können ? Ein Kohlekraftwerk verbraucht im Jahr einen Würfel mit 100m Seitenlänge an Kohle! Das sind über 5 Mio Tonnen Co2 !!! Ein Kubikmeter Luft hat ca. 1kg, also sind das 5 000 Mio Kubikmeter Co2. Lieber 2x2x2m Uran !!!

[apeson89]

@DiggaBua Wenn die Kohle mal reicht...könnte mir vorstellen dass es noch mehr ist. Die bekommen die Kohle ja jeden Tag per riesigen Güterzügen...aber die Sache mit dem Uran ist trotzdem arg heikel...wenn der Würfel in falsche Hände gerät wirds schmutzig!

[EsterinMovement]

@apeson89 lol u dont know anything about handling energy....

[NorEaster07]

I love the people who respond about fuel cells who know nothing about it. The same people who said "gasoline is too dangerous, it can blow up!". Or better yet.."we have candles, who needs wires inside our walls?" OR "wood is cheaper then oil, why should we use up our oil in the earth?".

[Phalanxpursos]

Humanity already destroyed so much.

Hydrogen is found no where on this planet but in water, if humanity will use Hydrogen as water it will cause serious drought & starvation. If you thought an oil crisis was bad, try to imagine what a Hydrogen crisis would be like. You can live without Oil, but you can't live without Water.

So everyone who wants Hydrogen as petrol replacement is a serious hazard to all life on Earth.

[radiods]

Firstly, you cant say that H is found no where on this planet but in water.. there are SO many organic molecules that contain hydrogen other than dihydrogen oxide (water).. what about all the hydrocarbons? Methane for example.

[radiods]

In this case, H is NOT derived from water. It can be, but the process is more expensive and less efficient than just deriving H from natural gases. H can also be produced through solar energy, which they're doing a bit of for the CITARO buses in europe, but is not widely used at the moment because with current technology it's not as efficient.

[sammyj13]

water covers nearly 2/3 of the earth, so i'm sure we won't have a hydrogen crisis unless the population hits 10 billion or so

[Shepson1]

Thats ridiculous. H2 is the most abundant resource on the planet. It's in water (both salt and fresh), fossil fuels, the plastic in your water bottle, the air you breathe, in the soil under your feet, in every living plant form and just about anywhere you can think to look. Secondly, when you burn hydrogen, you get steam (with H2 in it).

[Shepson1]

IE, you're not using something that isn't immediately replaceable (like oil). It's not a loss-less process due to heat loss, but using H2 won't cause a drought. It might rain more though. :o)

[my83merc]

even very inefficient hydrogen vehicles say they consume 1L of Hydrogen for every 5 miles (mind you that is very inefficient for todays standards in hydrogen cars) still produce few enough emissions to be considered a "Zero Emissions Vehicle". Fewer CO2's no matter what wikipedia tells you... :-D

[manolis1080]

this car is a fraud according to wikipedia it doesnt produce less CO2 its just capable of burning Hydrogen in a old technology not energy efficient internal combustion engine plus there is the problem of where you can find Hydrogen plus it takes long to fil up on hydrogen

[sikunis]

when you burn hydrogen the product will be water. you should learn your chemistry

[manolis1080]

yea but today its too expensive to make hydrogen frm solar power so they use petrolium so they produce CO2 ! to make Hydrogen for Hydrogen cars.. plus hydrogen 7 is usually burning gasoline (hydrogen is still rare..) thus producing CO2..

[basketci90]

it is really great for our environment

[HAL11000]

No its not. The most cost effective way to extract hydrogen is through fossil fuels. This is why many automotive companies are doing research on hydrogen cars rather than electric cars. It is better to apply hydrogen fuel-cell technology on solar homes rather than vehicles. I bet the same amount of hydrogen to power that Beemer a hundred miles is more than enough to power a home for the entire winter.

[ROCKSOLID19]

The technology exists, lets use it.

[98209276]

hydrongen power is very efficiant i wonder why we are currently useing oil for fuck sake.

[Psgpimp16]

luft=air

modus=mode

benzin=gasoline

[carbonfreefuel]

Thanks BMW it was great seeing you in San Antonio, Texas at the 18th National Hydrogen Association conference. The ride and drive was a huge success.

Sincerely,

Andrew John Heath

[extreme111oc]

Nice video... i want this car

[cant7think7clearly]

LOL - I love the windmills in the background. Hydrogen isn't clean, it comes from oil at present you gimboids.

[imkansizartikbu]

hydrogen just needs more energy to be produced than the amount which can be taken from. But whether using or not using fossil fuels to provide the energy needed at the time of hydrogen extraction is just up to supplier..

[carbonfreefuel]

it doesn't have too come from oil just split water

[fpstina]

you can get hydrogen from other sources than oil genius... think... THEN speak.

[cant7think7clearly]

It uses too much electricity to extract it from water. Do a little research and you'll see just how much electricity. Just to convert 1 bucket of water you'll need 2 weeks' worth of normal household power. Try converting enough for a thousand cars. Hydrogen from oil is cheaper.

[Shepson1]

It may be cheaper now, but not in the future. And oil isn't renewable, or clean (cite the quickly increasing rates of asthma). We have an opportunity to switch the infrastructure over now. There's no reason not to.

[cant7think7clearly]

You're exactly right, but governments wont switch to cleanly sourced Hyrdrogen. Perhaps there's no money in it? Maybe it's too hard?

The only thing we know for sure is that it's easier to get all our Hydrogen from Oil. Believe me, if Hydrogen was sourced from clean renewable sources I'd be all for it.

[Shepson1]

I think the reason govts won't switch over now is because of money and power. You're into research... find out how many millions of campaign dollars are donated by big oil companies and big auto makers, both of whom stand to lose a LOT from cleanly sourced H2. There's plenty of money in clean H2 in the way of jobs, research, and manufacturing, and nothing is too hard for the dedicated.

[Shepson1]

There's just no stimulus to make the required changes to make H2 work. It has to be mandated by a government that will only make a mandate if the public outcry is loud enough. And there are far too many ignorant haters out there to make an outcry loud enough to offset the billions of dollars.

[halusinojen]

a.q.

[naturalmotionraptor]

Just beautiful. I wonder if it can run entirely off hydrogen. That would be the perfect car, so long as the electrolysis at the begining runs of solar or wind power. Water in, water out. Solar car. Perfect.

[Ailanto]

Cool! let's begin avoiding fucking Oil

[sandcrab132]

i just wish it wasnt in german :P

[hildegueden]

i wish i knew german
