BETE - The engine

Blue Energy Thermal Engine (BETE) is the heart of Blue Energy innovation. BETE is a versatile heat engine that can be used in all applications which require thermal energy extraction. A prototype will be built for off-grid electricity generation, of which household of averaged family will enjoy the benefit. Of course, to put this engine in other applications would need some accessories change. For example, in order to make flying car, we need to combined BETE with buoyancy engine. That is another topic of discussion.

There are well established business around the world in transport. This invention would be a good news to them due to potential energy saving. There is potential outcome that low energy efficiency heat engine, from traditional reciprocation engine such as ICE, to turbine style jet engine, or steam turbine, will lost their value. Though we might also face unwilling attitude from these corporate giants. Blue Energy is not only planning disruption in transport, electricity and energy production, it is also prepared for the tough business venture.

At the moment, car makers don't have to worry about directly facilitate fuel production and emission sequestration after the sales of vehicles. Blue Energy will change that. Future cars will not have mufflers. Instead, with BETE inherently pure oxygen combustion solution, and cryogenic expansion, fume will be locally stored for renewable energy fuel production

Transport solution

for land and sea:

There are many web pages in this site have described BETE features. Because land vehicles and sea vessels are working with the same principles, we will combine both categories into one section. We will have following table to further compare what could be different when using a BETE for a car or a truck
