- The Cologne region, or on a larger scale the Rhineland as a whole, has a wide-spread chemical industry, that has been producing large amounts of hydrogen as a by-product for decades. HyCologne has taken the leadership in an initiative to supply this hydrogen for ambitious trendsetting projects at attractive conditions.
Since May 2011 RVK (Regional Verkehr Köln) as a local public transport service provider is operating two hydrogen fuel cell busses under normal transport conditions. These Buses are operated jointly together with European Partners under the CHIC Project: www.chic-project.eu.
This is very educational.
We have to safe our environment from polluted air
I also want to see regenerative braking systems fitted on all busses, today. This goal should have been attended to a decade ago.
It does not matter if it is feeding into a resistor grid. Even diesel busses benefit from regenerative breaking. Hot brakes do not work too well on heavy vehicles. By keeping the brake temperature down, the safety and efficiency of those braking systems are increased. Look up the Voith fluid retarder; an accessory which mounts onto the vehicle's gearbox.
As vehicle body producers become accustomed to installing these dynamos, they can gradually start storing power in the vehicles ignition and accessory battery systems. Finally, an advanced regenerative braking system can be fitted to this fuel cell vehicle, storing everything it generates 100% of the time.
You are so right. The supercaps make so much sense in this inner-city bus, because it is braking and accelerating all the time. A Diesel engine could be designed much smaller and turned off during stand-still. Of course, fuel cell is even better.
wow! Nice video.. How much does it cost though? Why can't we use water and make the hydrogen on runtime and then use it in fuel cells? That would be less riskier than carrying the hydrogen bomb overhead. wouldn't it be?
One really does wonder why we just dont pool our minds together and quicken the transition to these non-polluting types of vehicles. Everyone agrees that electrical and hydrogen is the fuel source of the future. Yet, no doubt, entrenched financial interests i.e. the fossil fuel industries, would rather us transition so slowly that by the time we make an appreciable shift the symptoms of the disease i.e. climate change, will by then become far more apparent than it is today.
Nothing is more dangerous than indolence. No sane person would jeopardize their health in this way. And yet, you have ignoramuses who don't know how to reason properly, who somehow mitigate the severity - or even the existence - of what burning fossil fuels does to the atmosphere, and thus, to our climate and thus, to our ecosystems. There really shouldn't be any debate about the existence of a problem. And it also should be understood that changes in climate have a high probability of inducing positive feedback loops between the effects caused by higher co2 in the atmosphere, which in turn become causes for further deletorious effects.
Systems theory should be apart of any curriculum that tries to explain climate change. But I suppose that is too abstract for most peoples comprehension? In any case, theres good reason why most scientists/intellectuals believe in the existence of climate change, and are justifiable terrified that if we don't do something now - at a stage where the disease is still not bearing many signs - it might be a situation of "too little too late", by the time it becomes incontrovertible.
Fusion power requires something to fuse.
It's easier to use solar energy as well as wind. I especially value the decentralization of energy supply, and as much else as possible, so as to reduce the political power of any one group, and to make it as easy as possible for people to boycott misbehavers. It's hard to boycott the Saudi government these days because of their control over oil, but if everyone simply used decentralized renewables like this, it's no big problem.
yeah Facts matter, nature works on it´s own way, the climate Change is a Long process which is Happening all over again and again. It´s not right to claim there is a Problem but the fact that we humans hit the numbers of billions and still growing is a extreme condition for the planet and it´s nature so the future is very dark in sorts of drinking water, living ground, resources, cutting down all woodlands and Pollution, the list goes on....
Facts Matter it needs to be done in a specific way. Certain cities would have to become green cities and certain roads and highways would have to become green routes. Norway has already done this to a degree but it has to come from legislative institutions as oil companies cannot be relied upon.
the future is this or salt water.
Well know they Gone sadly
