Green Energy from the rise and fall of tides Printer Friendly Version
Background: Every object that floats in tidal areas (harbours, the sea, etc.) moves up and down with the tides. The energy that is required to lift the object and the energy disipated as the object descends is all wasted. (Imagine the energy required to lift a relatively small 2000 tonne barge.)
Practical Application 1: This energy can be harvested by connecting the object to a harbour wall or seabed. The relative movement between the fixed harbour wall etc. and moving object can be made to pressurise hydraulic fluid, this can operate an hydraulic 'wobble pump' which turns a generator.
Practical Application 2: In its simplest form this electrical energy would be cyclical, in line with 'still' high and low tides. In this simple form the energy could be sold to a national grid.
Practical Application 3: There are approx. 1500 harbours around UK. Most of them have underutilised harbour walls (built prior to the shrinking of our fishing industry). The oil industry alone discards many barges as 'unseaworthy' and sells them for scrap. A 'nodding donkey(s)' based on a harbour wall, one arm attached to a rising and falling barge and the other to a hydraulic piston(s) would produce the pressurised fluid necessary.
Practical Notes:
- Most forms of 'green' energy are complex and expensive. This one is DIY in its basic form and should provide money from selling power to the grid (in UK).
- The floating body should be relatively wide and long (not deep draught). Hence the 'barge' suggestion.
- To stabalise the electrical output - generator output could be passed to the windings of a bank of alternator/flywheels. Ideally, these would be rotating in a vacuum and suspended by magnetism (giving zero mechanical friction).
Reward: That if this idea is put to use and developed, that process in no way limits other users from using and developing this idea.

World Academy Printer Friendly Version
I want to see an international orphanage/boarding/university established that will take in thousands of poverty-stricken children from around the world and educate and provide for them with the best the world has to offer. Upon graduation from the university, these children will be equipped to return to their native lands and use their skills for the greatest possible good of their peoples.

Political candidate background information database Printer Friendly Version
We need a website that lists all registered candidates for upcoming elections and that provides potential voters with as much information on each candidate as possible, such as their:
-voting history, if already a politician
-education
-affiliations and associations
-criminal record
-stance on issues (major and minor)
-articles written about them
-awards, commendations, etc.
-criticisms of their actions and policies
-ideology
-biography
-achievements
-any controversy involving them or their actions or those of their associates

This website must meet the following criteria:
-not-for-profit
-does not recieve corporate or political funding/contributions
-non-partisan, and as unbiased as possible
-moderated and cross-referenced for accuracy
-easily accessible to anyone
-free
-easy to navigate
-well 'advertised' via public service announcements to maximize awareness of the service
The idea here is to educate and thoroughly inform voters so that they know all about who they are voting for, so as to not get screwed by greedy or flip-flopping politicians. We need third-party information that is more trustworthy (fact-based) than what the politicians speak of themselves, because they will often say anything to get voted into office. Once they are in, they can do whatever they want even without the approval of the people who voted for them; so being able to estimate a candidate's pros and cons can be an invaluable tool in ensuring true democracy and representation.
I hate voting because I never know anything about 95% of the people on the ballot and therefore vote for the most familiar name (which is almost always the candidate with the biggest campaign budget) or based on party affiliation. I always feel like I'm giving my car keys to someone I just met...not a good idea; And it is way too hard and time consuming to research all the given candidates.
Reward: informed votes = more accurate representation = better politics!
