Three Useful Inventions for the Environment

Now this is nice to see. Someone posting something other than a homework question.

I have had a look.

patent # 2005100020 - I am not a mechanical engineer and have not fully read the patent, but from what I can see it shows some promise.

BUT

Patent #2006100565 - Interesting idea but will use up far more resources than it will save, compared to other fixed transport means (ie- trains). For example - the cost of copper at the moment is so high it requires a telescope to see! The infrastructure required is going to be the biggest problem. Requiring it to be powered from roller tracks on the ground is just not viable at all. I have included an example dirigible under development which does show promise below.

Patent # 2006100615 - Cannot see any way of getting this to work. The heating effect of the sun is negligible (for a start), and the huge mass of the engine is going to further weigh down any (if any) performance. Analysis of resources used compared to other transport means is abysmal. Miniaturization of the process is not possible to counter this. This effectively boils down to a free energy device. Enough said.

These two show major problems that would clearly present themselves when you tried to build a prototype or model the system.

Someone more experienced in wave energy theory and hydraulics may want to comment on patent # 2005100020.

The numbers indicate patent applications, not patents. #2005100020 is useless, and "guest's" lawyers are ripping him off if they're being paid even to file this nonsense. The sole advantage over more direct means to convert wave, current, or wind energy to electricity is use of a storage tank to permit a time difference between harvesting mechanical energy, and generating electrical. RESERVOIRS for this purpose already exist, and are far larger and cheaper (cost per volume stored). Unfunny Rube Goldberg design elements dominate the pictures and descriptions. Example #8: float on sea surface operates lever, driving first hydraulic sytem, which pushes connecting rod to turn first pulley. It drives a scond pulley via a rope, and that drives a third the same way; the third moves another connecting rod to drive a second hydraulic system (!), the output of which is yet another connecting rod / pulley / belt ("rope") / pulley / connecting rod sytem to move the piston in the cylidrical storage tank "like the syringe" to suck in water through pipes which are thin "like needles" so as to take advantage of capillary action, but with one-way valves. Water released from the tank makes a waterfall [sic] which drives the electric generator. Despite the use of seawater, most components are to be made of aluminum or steel. No, no, no.
