Electric Kart

Looks like bags of fun

132.9mph off and walked away. Gear is good, gear is good, gear is very very good

Seems like a regular kart, but excessively heavy. Alright, 128HP is a bit more than what you'd expect from something like this.

It's also bullshit. Uh-huh-huh-huh aside, the motor might be rated to 400A x 250V but they're not using that. Or if they are, it's all going on squealing and raping the rubber.

Electric delivers torque. Power is a different consideration. I don't consider it proven on the basis of that video.

Power is how hard you hit the wall . . .

Torque is how far you take the wall with you!

saw this a while back, boring video of some guy just destroying go kart tyres.

Luddites.

Like it or lump it leccy power IS the/our future.

IC engines are almost ready for museum use only (in evolutionary terms).

IOM Leccy bikes were sneered at but no one is laughing as much now.

[Rogerborg]

Yes, they will be the future, but they won't be the present until we have energy storage that's:

High density or very fast charge and with a DC grid and big local energy storage points at 'filling stations'.
and
Light, i.e. not lead based.
and
Cheap, i.e. made of common, easily worked materials.

We can currently manage at most two out of three. That doesn't mean that we're 2/3rds of the way there.

Yamaha's PES-1/PED-1 project seems to have gone a bit quiet, pun intended.

Currently over 3/4 of the electricity we generate in the UK comes from fossil fuels.

The perecentage of electricty generated by 'renewable' sources seems to be exactly the same as the percentage of pump-diesel which comes from renewable sources - both are at 7%.

The difference making up electricity is nuclear power, of course... all existing plants I believe have ten years or less life left.

Storage of energy can take many forms. One is to make an 'artificial' fuel which can be used in internal combustion engines, as has worked well in Brazil for some time, never mind those running their vans from the back of a chippy.

The electronics in bikes and finding a decent electrical-energy storage medium are massively different. The former is very specific to motorcycles and often is technology that has been found in cars for many years. The latter is a problem which spans many industries that is a lot more complex, has a lot of people working on it, but no obvious solutions that are THAT close.

By that logic it's probably all a moot point because we'll be using personal teleporters soon anyway.

105 years ago 'A trip to mars' imagined a bit more than the moon.

Even if we had amazing battery technology, teleporters are more likely than us being able to solve the energy transfer issues to get a full tank at the same speed as an ICE vehicle can.

Unless you go with fuel cells.
In which case, might as well go ICE anyway, which is, for the moment considerably better at releasing the energy.

[Rogerborg]

I hear that any sufficiently advanced technology is indistinguishable from magic.

We need a carbon, iron, silicon or aluminium based high-capacity, quick charge battery technology. Cometh the hour, cometh the... wizard.

Oh and while we're at it... where's all this extra power going to come from anyway?

We're already importing about 5% of our electricity from France, but their needs are growing and they export to other countries too.

If you want everyone to also be using electricity for vehicles, you've got a lot more demand.

If we go back to 'changing the way we approach the issue' - light weight bikes that don't go that fast with low power requirements used for short regular journeys - it's not a big thing as they can be charged using relatively low power and overnight when power demands are low.

Replacing a current car or motorcycle in all forms isn't going to work so well, however.
