New York gym rats can now not only build muscle power, but electric power as they pedal on fitness bikes designed to light up their own health clubs.
“Electrify your workout! Later this month you will be able to shrink your waistline and your carbon footprint all at the same time,” a motivational poster says at New York Sports Club, urging clients to use “pedaling power to help create a healthier planet.”
About 20 clients pedaled furiously under the poster on stationary bicycles turning sweat equity into sweat electricity.

“It’s a great idea, really fun. It allows students to monitor themselves, the monitor tells you how many watts you’re creating. It’s a win-win situation,” gym instructor Rick Meadows said.
The mechanism is simple, using dynamos on the bicycles to transfer 12 volts of electricity produced by the cyclists’ pedaling to a generator that creates alternating current of 110 volts.
From there, the current helps power the gym building and reduces its bills — although not the subscriptions for members.
“I invented the system in early 2007 in Connecticut, where I live,” said Jay Whelan, 46, CEO of the Green Revolution.
The commercial debut was made last year in California.
“We began in Washington two weeks ago and here in New York,” Whelan said, adding that there are 40 customers — so far only using spin bikes.
It takes 20 people to create about 3 kilowatts in a one-hour session.
In other words, with four sessions a day, the gym creates 300 kilowatts a month, which is the same as the power needed to light a typical home for half a year.
Over a year, the gymnasts can power the equivalent of 72 homes for one month, the company said.
A small gym might even be able to run its lights entirely on human power, Whelan added.
Green Revolution employs 45 people already and is looking to expand by putting the technology into other machines, including ellipticals, cross-trainers, stepping machines and recumbent bikes, the company says.
Each individual bike generator costs US$1,300.
The dual-purpose gym session appeared to have won over clients at New York Sports Club.
“You are burning energy and at the same time you use it for something positive,” architect Richard Kronick said.
“It’s fun, challenging and efficient,” said Felicia Rubin, a housewife.
Meadows shouted encouragements while green lights indicated how many watts were being generated, so that each client can see just how much electricity his legs can create.
“I created 69 watts, but I have to stop, to change the music,” Meadows said. “Somebody created 105 watts. Competitiveness in the class encourages people to do better. And people love the fact that they are creating energy.”
“All my members want to come back to see how many watts they create,” said Jennifer Carswell, fitness service manager.
Green Revolution has several dozen clients in the US and Canada, including at schools, universities and a homeless shelter.
National Taiwan University (NTU) yesterday said it disqualified a person from an entrance examination for using AI smart glasses to cheat, along with two others for making untruthful statements in their curriculum vitae. The three applicants were given null scores, Taiwan’s highest-ranked university said, calling on prospective students to be honest in the admissions process. NTU registrar Lee Hung-sen (李宏森) said that the cheating applicant wore a hat and thick-rimmed glasses to the second written exam for medical school, claiming that they felt cold. Suspicions were aroused when the applicant stared oddly at the test for long stretches while steadily bringing the paper
A magnitude 7.8 earthquake struck off the southern coast of Mindanao in the Philippines at 7:38am today, prompting the US Tsunami Warning System to issue an alert for neighboring countries, including Taiwan. The system issued a purple alert indicating a "tsunami threat." The potential threat zone includes Taiwan, the Philippines, Papua New Guinea, Yap and Palau. Philippine authorities were assessing the damage from the quake, with the office of civil defense seeking to verifying initial reports that 15 people had been killed and 129 injured in the region, mostly from falling debris. Arlene Hollero, disaster chief of Maasim town in the Philippines' Sarangani Province,
‘GRAY ZONE’ PRESSURE: Beijing’s activities are intended to create the deceitful impression that China has jurisdiction over the area around Taiwan, the CGA said Taiwan’s rights over its territorial waters and exclusive economic zone must not be violated by any country, the Mainland Affairs Council said yesterday, adding that it will not accept any unprovoked actions. The council issued the remarks in response to the China Coast Guard conducting maritime enforcement drills near eastern Taiwan and claiming to fully exercise China’s maritime administrative law enforcement authority. The Coast Guard Administration (CGA) has been closely monitoring the situation and is taking concrete steps to defend the nation’s sovereignty and secure its waters, the council said. China has no sovereign rights over the waters off eastern
Heavy rain is expected to affect parts of Taiwan this week, the Central Weather Administration (CWA) said yesterday as a meteorologist said the active part of the annual plum rain season has started. A stationary plum rain front and southwesterly winds would bring unstable weather and abundant moisture to Taiwan from today for about a week, with the heaviest rainfall forecast for tomorrow and Wednesday, the CWA said. The agency said western and northeastern Taiwan, and mountainous areas in the east and southeast, could expect showers or thunderstorms on those two days, with localized heavy rain possible.
