Hi Cor and All,  Fact is as much as I like SC leasing is very expensive compared to owning.  SC makes almost ALL the money though makes clean power which isn't bad. But the low cost high profit way owning is far better with paybacks in many places

Re: [EVDL] EV Boat

  Hi George and All,    That is a lot of boat drag to either go fast or far.   Just not a great choice for solar power.   Next since it can only go max 5mph on E and few miles depending on your battery pack hard to justify it.  And no need of expensive controllers, E cycle

Re: [EVDL] Temperature rating (Was: ENERDEL Battery Experiences)

Re: [EVDL] EVLN: 18 wing-motor NASA electric aircraft concept r:200mi

   Hi Peter and All,   While interesting it has a fatal flaw as small props are far less eff than say 6 larger ones in thrust/kw. Large props and low rpms is the key to range.   In an EV such large unneeded losses just don't fly as kills

Re: [EVDL] EV range needs, future best options

Hi Peri and All,  With some accessories you can cut that way down by a transport system approach.   I need most of what you say  my solution is a 2-4 seat EV with 60-120 mile range that tows a convertible lightweight aero trailer making it into a van, camper, flatbed, pickup.   

[EVDL] EV range needs, future best options

    EV range is interesting as so many new factors.  While long range is nice for those that actually need 100+ miles/day, most just don't need over 120 miles I see as a sweet spot for most.    For many just a 60 mile range EV can work as many in Fla seniors only use Golfcarts and

Re: [EVDL] Help! - Double motor failure!

  Hi Dan and All, Likely overloading it by not enough gearing without any other details is the best guess.  Also you need to run in new brushes for an hr or so no load on 12vdc or what happened could happen.I'm doing that now with my D+D ES31,the big brother to yours getting my Ewoody

Re: [EVDL] What is needed to build a successful practical solar vehicle.

  Hi Dale and All,    With panels so cheap why not use enough to cruise at least 6mph. sunelec , others have them $.50-.80/wt.      Or put a full 2-3kw on it and connect it to your home powering it when not motoring would be useful, cool.  A new

Re: [EVDL] EV/Hybrid-to-home emergency power

    Hi Robert and All,  I've found the monthly utility fee covers the battery, generator cost to go offgrid in most places.  Some charge $50/month just to stay ongrid.       As the generator is set up for heat production cogen saves even more.
