What are some energy effiecient inventions?

Question

I need a few energy efficient invetions for a science project and I'm stuck! An example (the only thing I can think of) of one is a fluerescent (sp?) lightbulb. Thanks!

Answer 1

A hybrid car.

A programmable thermostat.

Insulation in your home.

Ground-source heat pumps that recover heat from the earth rather than burning fuel to make heat.

A solar panel or wind mill.

Heat recovery boilers, that make hot water or steam from waste industrial heat.

CO2 sensors in office buildings that only bring in cold outside air when the air needs ventilation.

The gizmo that shuts off your computer monitor when you haven't used your computer in a few minutes.

Motion detectors that turn off the lights when no one is in the room.

Sparking pilot lights, that make a spark to light your boiler instead of having a pilot light that is lit all the time.

Photocopiers that shut down when no one is using them.

Heck, anything that shuts itself off when no one is using it.

Variable-speed drives that power down fans or pumps when only a little bit of air needs to blown across something or only a little bit of water needs to be pumped.

Fine-bubble aeration systems in wastewater treatment plants that disperse the oxygen through the sludge instead of using huge blowers that make big bubbles.

Great question.

Answer 2

Nanodetonators . Believe it or not there real . I put in for a dealership. We will be selling them this summer . Forget about gas it will be obsolete .Use all the energy you need clean and cheap

Answer 3

There are numerous energy efficient improvements today. The one you are thinking of is the CF or compact flourescent, which is not as new but has been greatly improved. Also available are LED lights which use even less energy. Many appliances that meet energy efficiency standards have an Energy Star rating to signify this. In the vehicle department my favorite fuel efficient type is the gas-electric hybrid. For the home there is solar panels and wind generators.

I hope this helps some!

Answer 4

there are these really cool light bulbs which you can get that you can programme to how dim or light you want them to be.
