Those crafty engineers over at the University of Western Australia have designed Australia's first electric jet ski, and invited folks along over the weekend to see in in action.
It might be not too far off for you to vacation on a lake and not feel guilty about ruining said lake when you have some jet ski fun on it. In fact, whether you feel guilty or not, many protected bodies of water around the world have put a ban on petrol-guzzling water vehicles. You might just want to avoid giving the park ranger a heart attack and tell them beforehand.
Built by a group of students, the project also had a fair amount of outside support -- including an exclusively designed motor from Submersible Motor Engineering, technical support from Total Marine Technology, and donations from the Australian Medical Association and Altronics. According to UWA, the jet ski can go for around 30 minutes in its current form, though more batteries can be fitted.
