A group of students at the prestigious Massachusetts Institute of Technology (MIT) are developing a fuel cell-powered motorcycle using an old Ducati as the mechanical basis for the project.

  • The project uses a Doosan DM15 model fuel cell, which offers an environmentally friendly alternative to combustion engines.
  • The module itself weighs only 2.9 kilograms.

What makes the project particularly interesting is the use of an old Ducati with a Desmo-Due engine, which was previously used in the first Monsters and medium SS models. The iconic tubular frame is also being used as part of the concept. 

Only the engine casing and gearbox are being retained from the original V2 engine. Instead of a crankshaft, the electric motor is housed in the engine casing while the existing gearbox is being kept in its original form and function. However, the power output of the motor and the storage and refueling of the hopefully “green” hydrogen is not yet known.

The MIT EVT project is using the Doosan DM15 model fuel cell, which has a peak output of 9 kilowatts or 12 horsepower. The nominal output is just under 2 horsepower, which gives an indication of the power output of the motor. 

The module itself weighs only 2.9 kilograms and can be supplied with hydrogen via a changeable tank. Two 10,000 mAh LiPo batteries are being used as a buffer storage for the drive system. The buffer is necessary to compensate for the delay in the fuel cell when no power is being drawn, as the fuel cell only produces electricity when “gas is being given”. Doosan uses this cell to power drones.

The team hopes that their project will inspire other developers to consider the use of fuel cells in transportation. Fuel cells offer an environmentally friendly alternative to combustion engines, producing only water as a byproduct. With the popularity of electric vehicles on the rise, fuel cell-powered transportation could be the next big thing. The team also hopes to raise awareness about the potential of renewable energy and sustainable transportation solutions.

Jurutera dari Massachusetts Institute of Technology (MIT) berjaya menghasilkan pembesar suara senipis kertas yang berupaya menukar sebarang permukaan kepada sumber audio aktif.

Pembesar suara nipis itu menghasilkan bunyi dengan gangguan minima dengan menggunakan sedikit sahaja tenaga berbanding pembesar suara konvensional.

Berdasarkan video yang dikongsikan, pembesar suara yang dipamerkan itu hanyalah sebesar tapak tangan dan lebih ringan daripada syiling satu sen.

Bagaimanapun, filem nipis itu boleh menghasilkan bunyi berkualiti tinggi tidak kira dengan bahan apa yang digabungkan. 

Ini secara tidak langsung memungkinkan teknologi baharu itu diaplikasikan pada sektor lain terutamanya automotif. 

Untuk rekod, filem yang digunakan bagi menghasilkan bunyi tersebut bergantung pada bulatan kecil yang terdapat pada lapisan ‘piezoelectric’. Bulatan kecil itu akan bergetar secara individu ketika aliran elektrik disalurkan sekaligus menghasilkan bunyi. 

Sementara itu, projek pembangunan oleh MIT ini sebahagiannya ditaja oleh Ford Motor Company sekaligus memberi bayangan bahawa teknologi pembesar suara baharu ini akan diguna pakai pada kenderaan pada masa akan datang.
