摘要:
Extremely fast dynamic control is allowed for hybrid PV/T (photovoltaic/thermal) distributed power production using concentrated solar power by manipulating the transmissive or reflective state of a capture element or mirror or lens that can pass highly concentrated solar light from one energy conversion device to another, such as a thermal collector and a photovoltaic receiver, such as a vertical multijunction cell array. This allows superior quality electrical backfeed into an electric utility, enhanced plant electrical production revenue, and responsiveness to a multitude of conditions to meet new stringent engineering requirements for distributed power plants. The mirror or lens can be physically articulated using fast changing of a spatial variable, or can be a fixed smart material that changes state. A mechanical jitter or variable state jitter can be applied to the capture element, including at utility electric grid line frequency.

Thermal, electrical and/or optical interfacing for three-dimensional optoelectronic devices, such as semiconductor device billets, allows high intensity operation, such as for receiving and transducing extremely high intensity light shined onto a small surface semiconductor optoelectronic device such as a photovoltaic receiver or cell, transducer, waveguide or splitter. This allows high intensity energy transfer for beam receiving, signal acquisition, and beam or signal generation for high intensity power beaming and wireless power transmission. Preferred embodiments include three-dimensional photovoltaic receiver billets capable of receiving thousands of suns intensity or high intensity laser light for power conversion, such as by using edge-illuminated vertical multijunction photovoltaic receivers. Heat sink holding structures assist in thermal and electromagnetic communication with opposing billet surfaces.
摘要:
New high energy operating regimes for high intensity energy transfer for beam receiving, signal acquisition, and beam or signal generation for power beaming and wireless power transmission are made possible by new direct thermal pathways for heat sinking, where an energy conversion device comprises a plurality of fins [1] originating from inside the energy conversion device; [2] formed from an energy conversion device component; and where those fins [3] individually support traffic in energy carriers essential to the function of the energy conversion device. This allows high energy thermal interfacing and high intensity energy conversion, such as for receiving and transducing extremely high intensity light shined onto a small surface semiconductor device such as a vertical multijunction photovoltaic receiver. This allows high intensity energy transfer for beam receiving, signal acquisition, and beam or signal generation for high intensity power beaming and wireless power transmission.
摘要:
Rapid pulse programming of a seed, to obtain improved germination probability, and increased root mass, and crop yield, by illuminating the seed with radiation of a wavelength distribution from 300 nm to 20 microns, with a minimum average irradiance of 0.2 Watts/cm2 and a maximum average irradiance of 7 Watts/cm2, and having a narrow specific range of cumulative illumination energy from ½ Joules/cm2 to 3 Joules/cm2 or a higher transition point cumulative illumination energy, so as to specifically engage an irradiance-sensitive and energy-sensitive hidden stimulative exposure response in the seed and so as to avoid illumination of higher cumulative illumination energy that would cause a different and destructive exposure response in the seed. Preferred wavelengths include one or both of Medium Wavelength Infrared (MWIR) radiation and an Indigo Region Illumination Distribution (IRID), which may be applied to an illuminated agricultural planter.

摘要:
We use permanent magnets to levitate and transport heavy loads. A bed of permanent magnets is selectively actuated to levitate an array of magnets positioned above the bed, such that the magnets in the levitated array are opposed to the actuated magnets, and of the same magnetic pole, thereby creating a repulsive force. The actuated magnets are offset from magnets in the bed of permanent magnets that have not been actuated, thereby imparting maximum levitation forces to the magnets in the levitated array. Our systems use magnetic repulsive force for levitating and transporting goods across a warehouse, simulating walking or running such as on a treadmill or in a virtual gaming platform, and for transporting people such as on a moving sidewalk. Our systems are electrical machines for holding or levitating devices using magnetic levitation, and also use permanent magnets to transmit power wirelessly.
