System and method of hydraulic gravitational energy generation
The invention is a system and method of generating hydraulic gravitational energy. Specifically, traditional gravitational electricity systems use a weight as a battery. However, the weight must be pulled upwards after it is dropped, which expends the created energy. In contrast, the disclosed arrangement employs a hydraulic system to lift the weight from a lower height to an upper height. Notably, hydraulics create more energy than is exerted. Thus, using hydraulics to lift the weight multiplies the energy produced each time the weight is dropped from a first height to a second, lower height. As a result, gravitational solutions can extend beyond non-traditional batteries, and can be used to generate electricity instead. |

Sound attenuator apparatus and method
Sound waves of an amplitude having a waveform (first value as a function of time and a first maximum) pass into a manifold, which subdivides flow and sound into multiple paths of differing length, yielding transit times offsetting the arrival of each instance of the waveform at an outlet or exit. This minimizes the addition of energy (sound volume, amplitude) arriving at the exit or terminus from each path. Amplitude is thereby reduced (although the waveform shape remains), repeated and offset by the transit time delays of paths discharging at the terminus. One may select the number of paths based on a desired reduction in the sound amplitude. That number is approximately inversely proportional to the ratio of the reduction. For example, six unique paths in an experiment reduced original amplitude (sound volume) to a sixth at an exit. |

Methods of making anion exchange membrane via simultaneous post-functionalization and crosslinking of epoxidized SBS
An anion exchange membrane is provided by converting carbon-carbon double bonds in the backbone of polystyrene-block-polybutadiene-block-polystyrene (SBS) into epoxide groups. Unmodified SBS is first partially hydrogenated to remove about 65% to about 90% of carbon-carbon double bonds. The remaining double bonds are then converted to epoxide groups to form an epoxidized SBS. UV-initiated ring opening reactions between the epoxidized SBS and haloalkyloxiranes are then employed to simultaneously functionalize and crosslink the epoxidized SBS. The halide groups in the crosslinked polymer network can be replaced via nucleophilic substitution to offer anion conductivity, e.g., via reaction with trimethylamine. Further ion exchange reactions can then be performed to make the membrane hydroxide conductive. The crosslinked membranes described herein exhibit a mechanical strength improvement of 200% compared to unmodified SBS, while maintaining high hydroxide conductivity. This synthetic platform is advantageous to provide mechanically robust anion exchange membranes for fuel cell applications. |
