The build of the KERS bicycle
mechanical kinetic energy recovery bicycle, flywheel This is a second video for demostrating how the Kers bike was build due to the large volume of questions received. The main video shows how the bike actually moves the bike. Main video link of the bike using mechanical KERS is shown here :https://www.youtube.com/watch?v=5FJcEvijjks
Grid Energy Storage: Beyond Batteries
nvestment in renewable energy infrastructure was higher than in fossil fuel infrastructure. With grid-scale energy storage, intermittent sources of renewable energy, such as wind and solar, become viable for the grid. VLAB will examine the technology and economics to make this transformation possible. The global market for energy storage services could be worth as much as $31.5 billion in 2017, according to Lux Research. Additionally, Pike Research forecasts that $122 billion will be invested in energy storage projects between 2011 and 2021. Today, 99% of the global energy storage is pumped hydro, which is geographically constrained. Now entrepreneurs free us from this constraint with fundamentally new technology challenging conventional expectations of capacity, efficiency and product life. Where are the best business opportunities for these start-ups -- at green energy farms? on the grid? or at the consumer's home or business? What are key metrics to make this economically viable, without subsidies? Efficiency, life-time costs, Capex? Will advances in traditional pumped hydro and compressed air prevail over battery/chemical technologies? Which countries are leading in Energy Storage on/off the grid? When will these new technologies become profitable? How and when will US utility companies get on-board? Join us to Learn More.

New York Engineering Grad Brings Hybrid Technology to Bike Design

He uses a fly-wheel to store energy generated by the brakes for use when the riding gets tough. Feeling the need for speed? If you're riding Maxwell von Stein's bicycle, you can get to your destination in a flash, without having to work up a sweat. The engineering student's fly-wheel bicycle employs the same energy alternating principles as a hybrid car. But rather than a battery, it uses a fly-wheel to transfer and store kinetic energy, which gives the bike a Boost in speed. To build the technology, he began with a 15 pound, cast iron fly-wheel taken from a car engine. He mounted the fly-wheel in the center of the bike frame, and attached it to the rear wheel through a continuously variable transmission. [Maxwell von Stein, Inventor of the Fly-wheel Bicycle]: "That transmission controls how energy is distributed between the bike and the fly-wheel. When you want to slow down you twist the transmission, it's a twist shift on the right handle bar. ... By shifting that ratio, you increase the speed of the flywheel and decrease the speed of the bike. Now the flywheel is spinning really quickly, you've got energy stored there and when you need to accelerate you shift the transmission in the opposite direction for a Boost in speed." Von Stein says he likes to think of the process as charging the flywheel and Boosting the bike. While his self-described "contraption" has made biking easier, von Stein says his goal isn't to re-invent the bicycle. He is hoping to use the two-wheel experiment as a basis for developing a fly-wheel kinetic energy system for cars. He believes the system is a good alternative to battery-operated hybrid systems because it is lighter and can be packaged more easily. [Maxwell von Stein, Inventor of the Fly-wheel Bicycle]: "Hybrids are really heavy. In order to get a battery with the capacity to store enough energy to move the car it's got to be pretty heavy. Takes up a lot of room also." Several European car companies are already experimenting with fly-wheel technology, and von Stein estimates that cars with regenerative braking systems could hit the market by 2013.
