The other end hybids

[Jasen]

I drive a gas guzzler, but I always get a chuckle when I look over at some 3 ton SUV and see a little green leaf badge. Was doing a little googling for a laugh...

Goliaths of the open pits have been using monster generators to power equally massive in-wheel electric motors for years, but GE is now testing a system which puts a battery between the generator and the motors, creating a true hybrid rather than just a monstrously torquey one.P

The new system integrates a 447 kW-capable, sodium-based battery from the GE locomotive division in place of the dissipative resistor system which previously was used to dump the heat of braking. Instead of wasting all that energy, the battery stores it up and uses it to get the mini-mountain moving again later.

We achieved 70% of fuel consumption partly because of the inherent characteristics of series hybrid system and partly because of special environment of the mine.
All data we collected points that expenses for conversion may be recuperated with 2 years after conversion by saving in fuel and maintenance. .

Now in a HOV-lane near you!

Hey, energy savings is energy savings no matter where it comes from, right? Do you have links to the quotes you posted?

I could just imaginr one of those things on the highway. It wouldn't be a HOV lane, it would be these are all my lanes!

but the more you guzzle the more you can save

13 civic hf - 33mpg combined - 3.0 gal/100miles
13 civic hybrid - 44mpg combined - 2.3gal/100miles

13 escalade awd - 15mpg combined - 6.7gal/100miles
13 escalade 4wd hybrid - 21mpg combined - 4.8gal/100miles


back when gm didnt have squat for hybrid passenger vehicles a field engineer told me that every hybrid bus that gm made saved as much fuel as 26 priuses

Yup, at least their trying.

Not much of a read, but here's the link's

Does saving fuel really work that way?
I could save a lot more taking just 1 Prius to work instead of 26.
Or even better 0 Priuses and just my Insight

Yes. If governments really wanted to ease our dependence on oil, we would be directing all our efforts at Tractor trailers, not hybrid passenger vehicles.

Not really, because there's not all that much to gain there, since a long-haul truck spends long hours at steady highway cruise, and (unlike most passenger vehicles) is not massively over-powered for that cruise mode. But if you keep up with news, you'll see quite a bit being done for stop & go applications, like UPS delivery trucks, garbage trucks, &c.

Also Hitachi has had a hybrid shovel out for a few years, Cat is making a quasi-hybrid dozer...

I think that I have mentioned that my friend talks about her hybrid Escape that gets the same mileage as Bacon, which is rated the same as my sister's much-newer Traverse.

Okay, so you insist on having an overly-expensive and large vehicle, and now you want to make it more complicated and expensive so that it gets the mileage of a slightly smaller and much cheaper vehicle? Genius!

Although a hybrid system delivers more percentual gain in stop and go traffic, it does help on the highway too.
Most of my driving is on the highway in one of the flattest countries in the world, yet even if you try to keep a constant speed the conditions (traffic, on/off ramps, bridges and tunnels, etc) bring lots of opportunities to store energy and reuse that.
Most vehicle types would benefit from having a hybrid system in most conditions.

You can win some for the idea of buying something smaller and more economical, but not all. Anyone would like a better economy, but not if they have to give up what they like.

Don't try to make people drive hybrid cars. Try making the cars people drive hybrid.
Who cares what the best hybrid is, as long as it is better than what it replaces.
