Oh wow, i had no idea about the ICE pusher concept, thanks for the input.
I've just googled it now, and that's an interesting idea. Interesting, but after analysed the cons, I think ICE pusher is far from cost effective and far from environmental friendly though...
Here is why:
- All the hassles that Christ mentioned above
- The money to purchse used or scrapped car with a running engine, $500?
- Time and money to make the pusher, DIY will be cheaper, paying someone to do it would be expensive
- Ugly, dragging such a weird thing at the back is not visually appealing
- Not aerodynamic, extra wheel drag
- Dead weight, the pusher itself weight more than a 5kW generator
- Pollution, the ICE pusher, I'm sure it won't be a 2010 < 1.5L small displacement engine, and most likely off some scraped 2000 car... and the displacement will most likely 1.8L+
Even if i buy 2x brand new Honda EU2000i, it will only be
200cc (2x98cc),
1.1 gal/ 4 hrs = 0.25 gal/hr x 2 = 0.5 gal / hr max, and it will give me 4kW, and will cost me 2500$.
Building an ICE, will most likely cost you 1500$ minimum.
