Automatic Road barricades!

Like most congested cities in the world, we in bangalore also have huge traffic problems, especially during peak hours. On many roads, the traffic is usually one-sided, meaning, it overflows on one-side, while the other side enjoys a very thin or no traffic situation. This is usually caused by concentration of large-scale companies on a particular location. During the day you will see huge traffic going towards this location and the other way in the evening.

Now, for the whacko thought - how about designing an automatic road barricades system that moves to widen the road on one side during day and do the opposite in the evening? For example, if we have two lanes of traffic on each side of the road, In the morning - the traffic-intensive side of the road will enjoy three lanes now while the other side would have only one (which is good enuf for that moment). What say?!

Using energy exerted in Gyms

All over the world, millions of people spend huge sum of money to exercise in gyms. How about some way by which we (humans) can make effective use of that energy? For example, people do treadmill, cycling etc in the gym. May be we could find some way to convert that rotational movement(energy) into some other useful form of energy (like electricity) and may be use the same for powering the gym itself?! Think about it...
