Hello everyone, Here is the concept of a small electro-solar vehicle presented in a more general way http://www.hkw-aero.fr/pdf/Michel_Kieffer_auto_%C3%A9lectro-solaire.pdf The problem of bodywork is developed in particular page 13, transport of loads page 31, a profiled variant page ...

Hello everyone, A lot of fun to find you on this good old forum :)! Here are some topics to complete your last posts: - small electro solar vehicle: the main ideas are the reduction and the adaptation of the autonomy to the real needs, especially not more. The huge mistake being to ...

… “The more complex the solution, the more its reliability becomes problematic (and expensive)”. As for the TWIZIE, its electric version is excellent in town for its lightness, but its improbable thermal version would also be excellent… quite simply because it would consume me considerably ...

Ahhh calculation data: | ! Consumption is systematically different depending on "who" publishes it ... Moreover, too often, the conditions for obtaining the drinks are not displayed. This means that x liters per hundred in “city road” use for example does not mean anything by rappo ...

In the series "we wonder ..." We marvel (but not us: cheesy :) in front of a 2-ton monster that consumes 6 liters, maybe 5 helping marketing, or even 4 helping rigging² liters ... while it should aim for 2 or even 1,5 liters and certainly a little less driving: http: //www.enviro2b ....
