Can a machine multiply input energy or work?
No. The machine can multiply input force if it's built to do that. But when it does,it divides the distance by the same amount. So the product of (force x distance)comes out the same as what went in. The product of (force x distance) is the inputwork, or energy, so that doesn't change.(In fact, some of it is always lost going through the machine, so what comes outis always a little less than what went it.)

How can a machine be useful if the output work is less than the input work?
Whatever we do, energy will be wasted. This can't be avoided; it's a fact of nature. Ideally, machines should be built to keep this waste energy as low as possible (although other criteria may also be important when building machines). Machines are useful for what they do for us. If, for example, we were to use our muscles to move things, some energy is wasted as well. In any case, we prefer to use a machine to do the moving, because of the convenience.
How much energy does a solar panel get from the sun?
It depends on the size of the solar panel and how well built the product is and the energy holding capacity of the battery.
What are the negatives of wave power?
some negatives of wave power is that the devices built to harness the energy of the waves are not adiquite enough to do so. So lots of energy is lost and some is gained. some negatives of wave power is that the devices built to harness the energy of the waves are not adiquite enough to do so.
