The spectrum of LOTEM data from receiver ST-01 (top), and ST-04 (bottom) are p We recognized periodic noise sources at 23 Hz and 60 Hz. Both noises likely come from the generator We recognized periodic noise sources at 23 Hz and 60 Hz. Both noises likely come from t and the power lines. ator and the power lines. The notch filter removes a narrow frequency band and keeps the remaining spectrum unchanged [44]. In our case, standard recursive filters have been modified for LOTEM to Since the receivers’ records contain both active and passive EM measureme avoid signal amplitude attenuation [45]. However, a different filter, such as a lock-in filter, different frequency rates, these must be separated by cropping and merging be is required, because in some cases, the transient cannot be recovered from the signal by quality control processing. During a data merge, the receiver and transmitter’s tim applying the notch filter. Specifically, the lock-in filter adapts to the phase changes of the periodic noise and subtracts the results from the acquired data [45]. In contrast to periodic synchronization, a time shift correction, the component’s polarity flip, and a re-s frequency, if required, should be applied. Once the merge has been completed, noise, sporadic noise from natural sources is difficult to recognize and, consequently, cannot be removed by filters. This kind of noise can be removed using mainly stacking techniques orded time series for both electric and magnetic components at each receiver an (Figure 8).

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com (Standard Web Page)
