Abstract: A seashore wave energy converting facility (10), comprising: an ascending ramp (12), being a sloped ramp installed at seashore line such that a lowered end thereof (12a) is immersed in the sea while an elevated end thereof (12b) is located above the sea level; a descending ramp (14), being a sloped ramp having a opposite slope with regard to the ascending ramp (12), the descending ramp being connected continuously by an elevated end thereof to the elevated end (12b) of the ascending ramp (12); a turbine (20) located under a lower edge of the at least one additional descending ramp (14); and a construction (18) for placing the facility (10) at seashore line; thereby enabling installation of the wave energy converting facility (10) at a seashore. The sea water may be directed to a spiral ditch, wherein the turbine is disposed, thereby increasing the power generation efficiency.

Abstract: A method and tool for facilitating data and commercial transactions over a public network enable a user to maintain full control of personal data. Information, including payment information, is provided by a supplier to a user requesting provision of a service or product. In order to facilitate a transaction, the user arranges, via a bank, credit card institution or other fiduciary organization, for payment directly to the account of the supplier together with an identification of the goods or service required. Thereafter, the bank, credit card institution or other fiduciary organization arranges for payment directly to the account of the supplier and identifies the required goods or service to the supplier. The goods or service are then delivered to the user. Such transactions may be optionally performed by use of a single step on the part of the user.
