Global OTEC has designed a floating platform capable of converting solar heat energy stored in the oceans into renewable baseload power. Fossil fuels dominate across tropical islands, driving GHG emissions and socio-economic weaknesses. They lack the space - or resource - for conventional renewables such as solar, wind and hydro to provide baseload power. Their reliance on imported fuels creates volatility, trade imbalances, FX shortages and macroeconomic weakness. Small Island EEZs represent 30% of all ocean & seas; 28 times greater than their land space. Tropical oceans absorb the solar energy-equivalent to 170bn barrels of oil per day. This can be harnessed using a well-known thermodynamic cycle. The cycle uses the temperature difference between warm surface seawater and cold deep seawater to repeatedly evaporate and condense a working fluid. The vapour produced runs a turbine which produces electricity. GOR has designed the first cost-effective system to supply to a market with an urgent need for alternative renewables. The power plant is contained in an innovative floating system, capable of conveying the cold and warm water, whilst also maintaining stability in the marine environment.

Around 800,000 UK higher rate taxpayers are owed money by HMRC and dont know it. We find it and help them get it back. If you pay into a workplace or personal pension on a "relief at source" scheme, your provider automatically claims 20% tax relief on your behalf. But if youre a higher or additional rate taxpayer, the extra 20–25% isnt automatic — you have to claim it yourself. Most people never do, usually because nobody told them the rule exists, and its fiddly to do. HMRCs own figures put the average unclaimed at roughly £1,756 a year, and you can go back four tax years. TEKKA works out whether youre affected, gets the contribution history from your pension provider, and files the claim for you. No recovery, no fee. If we do recover money, we take 10%. You can do all of this yourself, free, directly with HMRC — and plenty of people should. Were for everyone who wont: because they dont know the rule exists, dont know which scheme theyre on, or dont want to reopen four years of Self Assessment. Or just dont want the hassle.
