What Do You Think?

Now a days smart phones sucks battery within minute, I have an idea that the battery can be charged by inserting a small SOLAR MODULE on the phone.

I have designed a Solar Collector, which can receive Solar Short Wave Radiation with Conventional Parabolic Solar Trough. The Solar Collector is made of clear silica Glass( 6mm thick). The Cross Section Glass is partly parabolic & its focus point is common with the main parabolic reflector. The axis of the Glass parabola makes 45 degree of angle with the latus rectum & axis of parabolic reflector. Solar radiation enters through the calculated opening of the glass. The Glass Screen is surrounded by the water tubes covered with Platinum black with 0.98 emissivity. The Glass Screen allow only short wave radiation wave length below 2500 nm. Total Solar collector system is covered with heat insulating materials. The shape of the glass is so designed that no reflected & radiated cant escape the system, and thus more than 90% of radiation will be absorbed.

Solar paint can help world by a lot.......if we can make a paint which has the ability like a solar cell then we can creat so much electricity......

i have an idea to run car without any type fuel. that car energize the power during the running condition . i think that car only initial investment there is no fuel cost.this is FUTURE CAR.

I'm a second language English teacher. I wasn't a science major, let alone an engineering major, so forgive my lack of technical elaboration. One of my youngest (and brightest) students has been brainstorming ways to generate or capture and recycle energy.

Today, he proposed capturing the waste heat energy produced by the friction between car tires and the road surface. Does that sound technologically feasible or potentially worthwhile, economically?

I am not an engineer by any means. Just someone with a few ideas. This idea is to generate electricity without using any non-renewable resources with no environmental impact. this simple idea uses the two most abundant renewable resources we have on this planet. Also without either one of them we wouldn't be able to survive anyway. The simple idea I have is just using water(salt or fresh but preferably salt) and pressurize it just using the sun. No coal,no gas,no fossil fuels at all. If we can concentrate the suns energy on the water such as a large magnifying glass or multiple magnifying glasses we could boil the water to steam in a pressure vessel. It then can turn a generator. Like I said before,I'm no engineer but you get the simple gist of it and can take it from here. Thanks

If you fit debris filtered turbines into major sewers can we generate reliable and strong sources of electricity?
Similarly on a smaller scale could homes achieve this at a local level (feeding their own power supply) by adding turbines to their own water outlet pipes?
The flow of water generates a constant energy fed by gravity we seem not to tap today.

This leads to...

Gravity is a force and therefore an energy you could harness to overturn the principle that perpetual motion is impossible. Without energy it is impossible, but gravity is an energy source.

Can it give sufficient energy to overcome friction? I don't know, but with engineering I think it can.

Take the principle of a simple child's swing on which the child can power their own motion simply by shifting their weight forwards on the forwards motion and vice versa backwards.

By engineering and use of low friction materials I believe it is possible to start a swing at one side with the seated weight loaded to carry it through to the other side extreme. Then, via engineering the seated weight trips (using a levered switch and gravity) to slide to the opposite side of the seat, putting the weight in the correct position for the return journey and replicating the weight shift pattern of the child. Possibly this release needs some electrical or magnetic energy input but hopefully less than generated.

Through engineering and the design of joints / levers / weight distrubution (shifts with gravity) and switches / magnets it should be possible to efficiently replicate the efficient action of a child to create the illusion of perpetual motion using gravity in an efficient machine to perpetually generate energy.

The energy is extracted via the axis point and by tapping into the movement of the seat - the same way a steam turbine would work today.

Challenge. Make it work!

Make a lightning hydrogen generator.

Plants as source to trap solar energy and then its use to human needs

I can increase to effiency of an ingine near about 99.8%
