It's electric, it's Ecycle

We ride a bicycle powered by a generator, which claims to generate more output than input.

The popularity of electric cycles is on the rise. The ability to pedal or go faster and further while being propelled by electric power seems to be gathering customer interest. Hero Electric sells a few electric cycles and so do a few start-ups like Spero. Among these start-ups is Punit Patel, a young engineer from Dahanu (a small village in Gujarat), who left his day job and spent three years developing an electric generator that can power a bicycle and maybe even motorbikes and cars among other devices in the future. To demonstrate the functioning of the generator he developed the Ecycle.

Two details make this mode of transport interesting. One, his bike has two battery packs. While one powers the cycle via the motor, the other gets charged via the generator. Two, the generator is claimed to be so efficient that it can fully charge the second battery well before the first battery drains. And this is without pedalling, also a means of charging. Theoretically, this means after the first grid charge you never need to plug in. In reality though, you will need to, as the batteries get hotter each time they are charged and their capacity keeps diminishing. But Punit expects the riding range to be far greater than what any electric bike is capable of today, before you finally need to plug in. The secret, Punit claims, is that the generator’s energy output is more than its intake. Yes, it goes against the laws of thermodynamics and this is what the inventor is struggling to prove.

The idea came to Punit around three years ago, when he was convinced that generators should be far more efficient than they were. He opened up a 5kW diesel generator powering a windmill on realising that it provided 4,000W, whereas technically it was capable of 6,714W. He started his research and while tinkering with the generator, noticed an inexplicable ‘spike’ when he changed various configurations of wires and magnets around. He fiddled around with few other bits which he prefers to keep a secret until he can sell this idea for mass production.

His efforts culminated in a ‘Self-Charging Generator’ (SCG) as he calls it, which creates more output than input. Punit then applied the same formula to a 48V system, which is at the core of the cycle.

Italian madness on 4 and 2 wheels

Despite the difference in wheel count, could the MV Agusta F4 and the Lamborghini Huracán share the same incensed Italian soul?

Driver’s seat or rider’s saddle, you are assured of grin-inducing thrills.

The F4 will scream to 14,000rpm, and the Huracán will thunder past 8,000rpm. Both subject a crushing force to those closest to them as the rev counter leaps towards the limiter.

Taking a peek at the heart of the madness is easier on the Lamborghini.
