Search MVTG and Mantra Energy Technologies for the 9 year SGSIF history on the company. The new part of SGSIF, the revenue part was a private firm MVTG bought in April called AWS. Alcoa Wireless Solutions. Yes, Alcoa Aluminum once owned owned them. So the history, PR wise, issued patents wise, partner wise over the years must be searched for as MVTG and mostly as Mantra Energy Alternatives!!!
