Best friend, 18, of student Richard Okorogheye, 19, reveals trolls prank called her during the two weeks he was missing to claim they had seen him or his body. before he was found dead in Epping Forest
Hala Mohamad, 18, was friends with student, 19, who went missing from home in West London on March 22
Richard Okorogheye was found dead on other side of the capital in Epping Forest two weeks later on April 5
Miss Mohamad received really stupid prank calls of people saying I ve seen Richard, or I ve found his body
She told her friends at the time that she was struggling to handle it because in a stupid way it gave me hope

Windfarms with turbines that rotate on an upright axis could transform the wind sector, a new study has found.

Based on over 11,500 hours of computer simulation, the research from Oxford Brookes University found that Vertical Axis Wind Turbines (VAWTs) boost each other’s performance when clustered together, with grouped pairs seeing a 15 per cent rise in output. This is in contrast to the more traditional Horizontal Axis Wind Turbines (HAWTs), which produce turbulence that affects the performance of other HAWTs downwind.
“Modern wind farms are one of the most efficient ways to generate green energy, however, they have one major flaw: as the wind approaches the front row of turbines, turbulence will be generated downstream,” said lead author of the study, Joachim Toftegaard Hansen, and engineering graduate at Oxford Brookes.

The now-familiar sight of traditional propeller wind turbines could be replaced in the future with wind farms containing more compact and efficient vertical turbines. New research from Oxford Brookes University has found that the vertical turbine design is far more efficient than traditional turbines in large scale wind farms, and when set in pairs the vertical turbines increase each other s performance by up to 15%.
A research team from the School of Engineering, Computing and Mathematics (ECM) at Oxford Brookes led by Professor Iakovos Tzanakis conducted an in-depth study using more than 11,500 hours of computer simulation to show that wind farms can perform more efficiently by substituting the traditional propeller type Horizontal Axis Wind Turbines (HAWTs), for compact Vertical Axis Wind Turbines (VAWTs).
