15-Pound, Retro-Tech Flywheel Helps You Pedal Your Bike To Tomorrow

Later, you can take that spinning energy and use it for something else. But you normally think of flywheels as enormous steel monstrosities spinning in factories. But 22-year-old inventor Maxwell von Stein's new bike employs a small flywheel to boost his speed and take a load off his legs while pedaling: When braking, the biker simply shifts gears and allows the energy to transfer from the back wheel to the flywheel (instead of transferring uselessly to the brake pads). Once the rider wants to accelerate again, he simply shifts the gear and the flywheel transfers that power back to the bike, sending the cyclist on his merry way.

The wheel weighs 15 pounds, so you certainly need the extra help it provides to keep moving. . / 10 Pin / 29 Plus / 50 Tweet / 602 Like / 13 Share. Attacking Shark Gagged by Slime. CIGUATOXIN.

Latitude/Longitude Distance Calculation My home page is here. I got the formula for this calculation from the math forum at Drexel University. If your are interested in the math behind this calculation then you can read their explanation here. Here is a page showing the important sections of the code that performs this calculation. If you are looking for a way to determine your latitude and longitude go to the find location page. Valid formats for Latitudes and Longitudes are:

10 Strange Things About The Universe - StumbleUpon

While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ? 273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below.

One of the properties of a negative-energy vacuum is that light actually travels faster in it than it does in a normal vacuum, something that may one day allow people to travel faster than the speed of light in a kind of negative-energy vacuum bubble.

Feature Article: Measuring Water Movement in Your Reef Aquarium for Less Than $100 — Advanced Aquarist's Online Magazine

Indeed, the ability of aggressive water to dissolve copper 'coupons' has been a standard for estimating the corrosiveness of potable water for a number of years. These coupons have also been deployed on natural coral reefs for study of long-term water motion). Obviously, dissolving copper in a small body of water (such as an aquarium) is a poor choice when long-term maintenance of invertebrates is the goal. Other materials, such as salt tablets and even candy (LifeSavers™), have been used.
