In the iMT's 3rd exhibition on batteries and their future possibilities, MIT researcher Barmak Heshmat shows a concept that allows you jump for few meters without breaking your legs!
Barmak Predicts that in less than 10 years the high power density of specific types of super capacitor-battery hybrids (MWh>kg) will enable mesoscale fast robotics (cm/ms). He calls these types of batteries "Surge batteries" which he has explained in his other posters.
He further adds: Such fast robotic systems are just recently emerging with other power sources (Ishikawa Watanabe’s ICRA 2009). This power density is still much less than motors with jet fuels which recently enabled hoverboards (Franky Zapata, France). One of the major problem of jetpacks and hoverboards is landing safely as in low altitudes (<100m); the normal parachute is not fast enough to operate. A surge battery which is an advanced supercapacitor can enable short bursts of electric power for a few bursts. This can be used to enable conventional parachutes. It can also be used to quickly accelerate and decelerate compact electric motors or enable fast memory alloy meshes. All these technologies will enable jumping and landing safely with a device that we are schematically presenting here. This fully electric jumper jet enables the user to jump high (<10 meters) and land safely no matter in what direction. The top gimballed blades accelerate when jumping up and the two lower sets work with a surge battery to decelerate when landing. This is not the simplest engineering design and we may see a combination of electric and fuel jets sooner (2020) than this design
Barmak's design is beautifully illustrated by Elliot De Vries, a concept artist that is the member of Imaginarium of Technology.
