That can't be right.
2300 kg * sqr(410000/3600) * 0.5 = 14893006.000 Joules
14893006J * 0.000277778 = 4136.9 watt hours
Edit: out of curiousity, in order to have a kinetic energy of 50GWh, it would need a speed of 1424260 km/h (884994 mph)
- redox99 3y agoYeah, it's quite clearly wrong when you realize that the batteries would never be able to deliver 50GWh in the first place.
- smcameron 3y agoAnd if they could, in order to charge it up, the battery would have to consume the entire output of the world's largest power station, the Three Gorges Dam, for more than two hours. (Three Gorges Dam outputs 22.5GW
- dsr_ 3y agoAnd would need about 750,000 of the best Level 3 DC fast chargers connected simultaneously. And 0.01% inefficiency in transfer would melt the car (and the road, and...)
- adrianN 3y agoThe video shows max power of around 1.3MW for like 10s. That's enough to get the right ballpark for the kinetic energy.
- shric 3y agoMaybe the GP assumed 410km/sec instead of 410kph.

- bombcar 3y agoI did based on 88 gigawatts being enough to send the vehicle backwards through time.
- kcplate 3y agoGreat Scott!
