Pendulum clock driven by three weights as "gravity battery". An old and simple application is the pendulum clock driven by a weight, which at 1 kg and 1 m travel can store nearly 10 Newton-meter [Nm], Joule [J] or Watt-second [Ws], thus 1/3600 of a Watt-hour [Wh], while a typical Lithium-ion battery 18650 cell [2] can hold about 7 Wh, thus 2500 times more at 1/20 of the weight.
Signs and symptoms are not mutually exclusive, for example a subjective feeling of fever can be noted as sign by using a thermometer that registers a high reading.

With millions of abandoned mines worldwide, a new study provides a compelling argument for their inclusion in a green energy future.
Prostate cancer is a form of cancer that is typically slow-growing and originates in or on the prostate, a male reproductive gland that surrounds the urethra in proximity of the bladder and rectum. This is a result of malignant cells forming and multiplying at the prostate, which can then spread or metastasize to other organs in the body. [1]
Some notable people who have been claimed to be suppressed, harassed, or killed for their research are Stanley Meyer, [17] Eugene Mallove, [18] and Nikola Tesla. [19] Free energy proponents claim that Tesla developed a system (the Wardenclyffe Tower ) that could generate unlimited energy for free.
