Just in the news:

Mexico City has started a women-only bus service to protect female passengers from groping and verbal abuse common on the city's packed public transportation system.

A strange side effect of crowded public transportation, his and her busses and trains.

Interesting design problem. I mean for buses and trains, not God's design of the female.

Just look at the huge amount of pollution generated by the old socialist countries of the east block!

Or the massive amounts of hot air socialists produce during their tirades against anything that reeks of personal freedoms...

Hot air! That reminds me, riding/flying in a hot air balloon is an interesting alternate mode of transportation. Even though the landing can be a bitch.

Landing is easy, the trick is landing where you want to in such a way that you can walk away from it and ideally use the vehicle again without major repairs :)

A trishaw, what a cute way to get around town.

As long as you are not the one that has to pedal the contraption.

Well there is also the bicycle, the rickshaw, and the trishaw powered by a human.

All of which produce masses of hot air and CO2... Not to mention human excrements in larger amounts than would be created had their operators not used them (and thus had to eat more to gain the energy to use them).

Plus for longer distances they're clearly impractical. Try biking from say Seattle to San Francisco. Unless you have a few weeks you're not going to get there in time.

Come on JW, you can't possibly be that dense. It is recommended for short distances, and you can't go to Hawaii with it. Large amounts of human excrement gets created no matter what, and it is after all biodegradable (has been for thousands of years).

What this world really needs is one dust powered vehicle. Hehe, I could power it up in my room.

So, in your hypothetical situation, there would only be one dust-powered vehicle and everyone else would still drive normal vehicles?

Or would only the owner of your one DPV be allowed to drive? (Hmmm...dust kicked up as others walk might give fuel savings...)

Well EnderX, there is a foreign thing called humour involved here. Bumsi, was telling you that there is enough dust in his room alone to drive one of those newfangled DPVs.

There is something misanthropic about cars that run on food. I can just see some rich jerk running a car on steak and eggs.

Hehe, haha, that's the spirit EnderX, deep down you are a funny person. Thanks for giving many of us a nice chuckle!

Great find twomers!

A car driven with energy stored in compressed air makes sense. As the air expands it cools off, so city traffic should keep the city cool in the summer.

Conversely, as you compress air it heats up. In bigger air stations this heat can be used to heat homes and businesses. Now we need just a good source of electricity to power the compressor.

I wonder why the big car makers (other than India's Tata) are not interested in this?

The nice thing about electricity is that it can come from many different sources, and sources that have no CO2 emission like solar, wind, hydro and nuclear. Using compressed air to store enough energy to drive a car might just be a very nice solution.

In warmer climates people could actually cool off on or next to a busy road. I assume that the air powered engine is rather quiet. If you can use the heat generated by compressing the air for other purposes, then that would be another plus. I wish the French inventor and India's Tata success.

looks like your mcdonalds car is going to die from cholestral very soon mate lol

how about promoting more battery powered cars that do a top speed of 70 mph.
That would be good for the ozone layer & less on speeding fines to pay out too.
Like most things in the world it is all found out that it is bad years down the line when the damage has been done allready , but we will be paying for it till we die.

Exactly what portion of the exhaust of a normal car is damaging to the ozone? I was under the impression the supposed problem was at a somewhat lower level of atmosphere.

And exactly how would the battery-car be any better? The exhaust would simply be factory-created rather than engine-created; you still have to provide power for those batteries.

I'm assuming this will not be done by connecting them with copper wire then flying a kite off the last one during a thunderstorm.

Simple and pretty dumb. You are suggesting that all methods of generating electricity give off the same exhaust.
0

yup. It all depends on how you calculate the environmental impact of something.
Under the current fad the only things looked at are CO2 and dust (for diesel engines) emissions.
10 years ago NOx was all the rage and had to be reduced to nothing (which caused an increase in fuel consumption as engines had to run richer mixtures).

But for now I'm going to make excellent use of the idiocy of the whole CO2 hype and get myself a Civic Hybrid as a company car with a massive tax incentive, saving me something like €150 a month in taxes :)

Wow, a thunderstorm powered car! You need to patent that one quickly!

China just annonced that it will spend $30 billion to connect Beijing with Shanghai via a maglev bullet train that can travel at speeds of up to 300 mph, cutting the travel time between the two cities in half.

They already have a maglev bullet train that connects Shanghai with its airport (20 miles).

Mass transit doesn't work, unless a lot of people want to make the same trips. In a city like mine, there are so many different possible trips that mass transit to cover even a tenth of them is prohibitively expensive.

St Louis began a mass transit rail system about 10 years ago and was an immediate hit. The trains are always full and there is a train going by each rail station every 15 minutes. When there is a baseball game at the down-town St Louis Cardinals Bush statium (no relation to our president) there is a train every 5 minutes. And the city continues to expand the system every few years with the overwhelming taxpayer support.

And its inexpensive too. The last time I rode it I could go anywhere I wanted for only $1.50USD. The St Louis airport is about an hour's drive from my home. Now I just drive to the nearest station's free paring lot, about 10 minutes away, and take the train.

And environmentally safe I think (electric engines).

I'd hate to be hit by a maglev shuttle.....

You'd never know what hit you and there would be no mess to clean up because there would be nothing left of you to find :) But I wonder what they will do about wild animals getting on the tracks ?
