This page is intended to give informations about the energy consumption of vehicles in general and the human and solar powered SUNDEM® in details:

Background Information: e-Vehicles

The old oriental dream of flying carpets has never become reality - at least not in our century. Even the best oriental carpets do not fly nowadays. The oil is the  thing we supply from there for our mobility demands and our replacement devices - the oil wich is used to fire our mobility dreams. We are all aware of the huge disadvantages of these solutions. This is the main reason why mankind focusses so much on e-mobility solutions based on renewable sources of energy now in order to ensure a good future to our children.

Remaining Problems: e-Vehicles

Cars are much too heavy and hungry for energy to be solar powered. New kind of battery technologies are in focus of the automotive industry now to keep the solution: move 1.5 Tons at average speeds of 60 km/h to transport in average 1.2 persons with small luggage - equals less than 150 kg net cargo. Result: A car moves in average 1/10 of its own weight and therefore consumes 10 times more energy than necessary. No chance for a solar generator on the cars roof to generate this huge amount of energy.
Bicycles are a great invention of mankind but sometimes too slow or too exhausting and they do not shelter rain and uv. Their weight is 10 kg only and they transport easily 100 kg net cargo with a average speed of around 20 km/h.
Electric power assistance to the bicycles on a e-bike is a great solution for short traveling distances around a charging infrastructure.

By the way: The necessary amount of energy for a e-bike could be generated by 1.5 square meters of solar modules if there is full sun.

We from VeloSolAir, as everyone else, cannot propose a Vehicle with all the advantages of a car leaving all the disadvantages aside. We propose, pursuing these arguments, optimizing in all main factors and parts and focussing on the major use case touristic travels a

New Kind of Product to Overcome the Energy Problem

A hybrid human and solar powered electric vehicle designed for up to 2, optimized in weight and aerodynamics and perfected to live the great freedom travelling on your own mind and your double power, pushed by the tail wind of the free solar energy wherever you go or travel - The SUNDEM®.

The Problem

ExhaustFlying carpets no longer exist, planes and cars consume more oil than Aladins lamp. They are not green in consumption. Bicycles are a great invention of mankind but sometimes too slow or too exhausting and they do not shelter rain and uv.

The Vision

fliegendestandem side onlyTravel with zero carbon footprint for free at friendly speed, enjoy the earth without regret and cost - something like the old oriental flying carpet - directly powered by the sun - no oriental oil anymore - pedals and a sun & rain shelter for every passenger to keep sane and get even fitter during the 'flight'.
