Jet-engined Jaguar supercar

Well, I didn't see that coming. Personally, I prefer the sound of a massive V10 but maybe that's just me...

[oldpink]

seen something on this a while back
something to do with being able to make the jet rotors small enough but strong enough
and the way they have to make them

When is this technology going to be on bikes then

there are electric powered bikes
but the battery problem is the issue, enough batterys to give it range makes it too heavy
light enough to go fast you get 20 mins then you need an hour recharge

they have a race catagory for what they call Zero emission bikes

Erm, none of these vehicals have a jet engine in them...

THAT'S a jet engine. The car and the bike both have gas turbine's in them, which isn't a new idea at all.

Even tanks are powered by them.

I really like the idea of gas turbine engines for power, and electric motors for power delivery.

The problem with gas turbine engines in cars (or motorbikes) where its connected directly, is that spin up speed is slow, gas turbine engines only work well at their running speed, not like piston engines that work well at a range of speeds.

The problem with electric motors, is that running on battery power alone, the batteries are big and heavy and use expensive materials, with limited energy storage.

Obviously at the moment, a standard hybrid car, isnt really that cost effective, so the gas turbine one is a bit silly, but in time the technology could develop to be sensible.

I think its a great idea, as the gas turbines weakness is made up for by the electric motors strength.

If the whole idea of investing in electric/hydrogen powered vehicles is to make the switch from fossil fuels. Powering it with turbines that run on gas/parrafin ect is a backward step.

The russians used to use them in combination with radioactive isotopes to power things.

The americans use them to power space probes and rovers as solar panels get even worse as you get further from the sun.

I stand corrected on the bike
I assume the shaft used to turn the props is connected to the sprocket

when I seen this on a TV show Leno said he had to be careful as if cars got too close
the exaust melted there bumpers

as to Jet or not I always assumed that gas turbines were jet engines using air rather than a Fluid

The problem with all these designs is that they are limited in fuel type. Yeah turbines aren't so bad as petrol engines in that they can run on anything flammable, but if wind or solar power becomes better they are useless. Electric vechicles are the way to go as they can be powered any way needed.

The other problem is that all current engines carry around with them not only their way of generating energy, but also their fuel. This is dangerous as well as inefficient. Due to the size and weight constraints power generation suffers. You can get diesel engines at 50% efficiency, but they are house size and bloody heavy. Again an electric vehicle wouldn't have this problem as your power generation would be separate from your vehicle.

This brings up a new problem though of power transmission and storage. People want to be able to go far in a car, so capacity must be high. This increases weight and decreases efficiency creating a real barrier. People also don't want to have to wait 12 hours for it to charge. Hydrogen can be created from water using electricity, then turned back to water releasing electricity. Hydrogen could also be refilled quickly. But then we are back to the problem of carrying fuel around combined with an engine again.

The best solution i think it magnetic strips under the roads to charge vehicles as we use them / park them. Yeah digging up the roads would be expensive as shit, but we seem to do it often enough already!

If the thought of powerful magnets in the roads sounds stupid as it will get covered in coke cans / children's bodies, worry not! The electric will need to be paid for. You will have a sensor under your car that identifies it, and activates the magnets to charge it, billing your account also.

Hi

Afraid I think pure electric is a dead duck, until someone gets wireless power transmission to work efficiently and able to carry high currents.

Only other way it will work is if a single battery pack design is used, and you fill up by stopping at a refueling point and the flat battery is unloaded and the fresh one loaded within a few seconds. This is probably the best solution, but also removes the quite hideous cost of replacing the batteries from the driver (otherwise a car that isn't that old is scrap when the batteries are worn out). Doesn't solve the weight issues with batteries though.

Current proposals for pur electric vehicles are pretty much useless due to range and refueling issues. Might work as a town car, but still leaves you needing another vehicle for the rest of your driving.

All the best

even battery cars are not good for the enviroment
nasty Acid / chemical mixes you need to dispose of eventually
and the more batterys a car needs more batterys the greater the waste problem
