2 To protect against loss of power to a nuclear power plant, use a water tower. Gravity can force cool water through the reactor until power is restored. E-mail
 
3 An ionic exchange converter for removing carbon dioxide from car exhaust to prevent climate change. (automotive, CO2, emissions) E-mail
 
4 2 satellites collided, spewing debris that threaten other satellites. To prevent crashes, a UN agency should track all orbiting objects and program a computer to predict their orbits and potential collisions. Satellites could then maneuver out of danger. E-mail
 
5 Divert carbon dioxide from power plants or other sources to greenhouses or fields to increase crop yields. Legumes may benefit most. E-mail
 
6 To better predict the magnitude of technological improvement, such as increases in oil reserves, use a top-down approach (extrapolating overall statistics), rather than bottom-up (trying to predict technology). Moore's Law is an example. E-mail
 
7 Put a water jacket on air conditioning condensing coils/pipes so that hot water can be created for free (and make the a/c more efficient!). E-mail
 
8 Focus solar energy (mirrors) to run a Stirling (heat) engine for pumping water or AC power, esp. in remote places. Use ambient air or nearby water for cold sink. Focus sunlight on water or molten salt reservoir for an even heat source (thermal inertia). E-mail
 
9 Instead of very heavy cast/fabricated steel supports/stands for equipment, try to design lighter (may be wider) open box type fabricated supports filled with concrete. Thus save on material, manufacturing, & erection costs of these items. E-mail

16 Design elevator button panels as a single surface (like on microwave ovens) that can be easily wiped clean for regular disinfection to prevent spread of disease via the hand-surface-hand route. Panel must have Braille for the visually impaired. E-mail
 
17 With universal, cheap cell phone service, a wide range of real-time, health monitoring equipment could be deployed. With 2-way communication, patients can be directed to take action before a crisis occurs. The cost of such capability will decrease. E-mail
 
18 The train average speed falls due to stopping at stations. Increase average speed by not stopping. Passengers enter and exit by a pilot box which will add to the front or detach from the back of the non-stop train near each station. E-mail
 
19 Spectacles / head-band with a small but focused lamp (battery / solar-charged) mounted in one corner (adjustable angle), especially for reading on bed / train / aeroplane. (eyeglasses, light) E-mail
 
20 Braking distance lights on the back of cars to let the person behind you know if they are following too closely. Could use a tacho to measure speed and use a laser for distance measurement. Weather conditions could be measured too. E-mail
 
21 Ceiling painting flying robot based on quadcopter technology. E-mail
 
22 Use the same technology to dissolve gallstones (ultra shock) to dissolve roots of teeth that need to be extracted (especially wisdom teeth). That way, the tooth is removed easily and the near liquified roots will drain out with the blood. E-mail
 
23 If I have a card where all my personal data is stored, and can be carried anywhere such as banks, then when I need to fill a form, I will just insert this in a card reader. It will fill in the form automatically. E-mail
 
24 A small sensor in the door which can detect the darkness and switches on the door step light whenever you open the door in the night to go out. E-mail
 
25 Instead of having your computer find drivers for a specific piece of hardware, have the driver itself stored on a chip within the hardware. That way you wouldn't have to go to the trouble of finding drivers for unknown hardware. E-mail
 
26 Design a plate, bowl, cup which will indicate the percentage of sugar and/or salt content. Like thermometer. To help diabetic and hypertensive patients. E-mail
 
27 To prevent tornadoes or hurricanes/typhoons from blowing out windows and roofs due to their low pressure, design buildings with vents allowing rapid outflow of air. E-mail
 
28 Place giant magnifying glasses over solar panels to concentrate the sun's rays and make solar energy more efficient. E-mail
 
29 A bluetooth device to insert into wall socket to measure electric usage and transmit to computer. Similar device to attach to wired devices like electric heater. Computer collects and produces usage graphics. Possible rental.
 
30 To allow blind individuals to use computers or graphing calculators, an adapter could be developed that represents the data on the screen in a tactile format. E-mail
 
31 An electric motor for a bicycle that is charged using a brake system that instead of transferring kinetic energy to heat, creates electric current (while reducing wheel speed), like hybrid-electric cars. E-mail
 
32 Walking chair for invalids: uses 8 identical electromechanised legs like a spider. It could be used for overcoming many of the obstacles faced by physically handicapped people such as staircases (including spiral staircases) and rough terrain. E-mail
 
33 Car companies should adopt frosted glass technology. When you park your car outside, you press a button and the windows become opaque. This keeps out the sun and hides the contents of your car from would be thieves.
 
34 Provide electric utilities without a grounded node. Isolation eliminates the most serious shock hazard situations. The traditional ground wire can still be used. However, grounded node might be needed to protect from lightning electrical pulses. E-mail
