zaidi. 00:06:11.150 --> 00:06:14.700 Ni vyema zaidi kuwa na mojawapo ya baiskeli hizi. 00:06:18.860 --> 00:06:20.625 Jina langu ni AJ Lawarence. 00:06:20.650 --> 00:06:23.000 Naishi Kaswa katika eneo la kati la Ghana. 00:06:23.075 --> 00:06:25.934 Akiwa na miaka 11, wakati Lawrence aligundua talanta yake, 00:06:25.946 --> 00:06:31.000 alijifunza kucheza na vifaa vya kielektroniki kama vile kompyuta. 00:06:31.425 --> 00:06:34.170 Mwaka mmoja baada ya mvuto wake kukua katika nyanya hiyo, 00:06:34.182 --> 00:06:37.000 alichukua kasi ya kurekebisha baiskeli. 00:06:37.001 --> 00:06:40.000 Hadi leo, bado anarekebisha baiskeli kadhaa. 00:06:40.100 --> 00:06:44.000 Kufikia sasa, Lawrence ametengeneza na kuuza baiskeli nne za umeme mwenyewe. 00:06:44.125 --> 00:06:49.810 Baiskeli ya sasa ina vitu vilivyoboreshwa ikilinganishwa na alizotengeneza zamani. 00:06:49.810 --> 00:06:51.831 Profesa Jaya anatazamia kuwasiliana na 00:06:51.831 --> 00:06:54.220 vyuo kwa ajili ya ushirikiano 00:06:54.250 --> 00:06:59.000 ili kuboresha mawazo yake ya ubunifu. 00:06:59.001 --> 00:07:04.000 Ana ndoto ya kutumia sola kuendesha baiskeli zake baadaye, lakini anahitaji 00:07:04.001 --> 00:07:06.927 ushirikiano na vyumo na taasisi za 00:07:06.939 --> 00:07:10.000 kiufundi ili kuboresha utengenzaji kutoka sampuli 00:07:10.450 --> 00:07:12.000 hadi kuwa biashara. 00:07:12.150 --> 00:07:15.005 Katika ushirikiano huo, anatafuta kuwafunza 00:07:15.017 --> 00:07:18.000 wanafunzi wa kiufundi kuboresha ufahamu wao kuhusu elektroniki. 00:07:21.900 --> 00:07:23.761 Nina swali.
