  7. Need advice - hybrid conversion

    All EV Conversions and Builds
    Hi there I am at the beginning stages of converting a Hyundai accent to a hybrid vehicle. I have reasons why I chose to go with a hybrid instead of a full electric vehicle. My plan is simple - power the AC motor with a generator. I calculated that I'll need an 11hp motor at minimum (I used the...
  8. Question about supplemental power generation

    Technical Discussion
    I was just thinking about different ways you could utilize an outside (or rather, inside) power source to generate energy as you go. This is not a free energy post. I saw a concept car they were making in Thailand that was basically a pneumatic car. The point here is that they were using two...
